+# RevenueCat Integration Guide
+
+This document explains how to configure and use RevenueCat SDK in BikeControl.
+
+## Overview
+
+BikeControl now supports RevenueCat for subscription management on iOS, macOS, and Android platforms. Windows continues to use the Windows IAP service.
+
+## Configuration
+
+### 1. Environment Variables
+
+Set your RevenueCat API key as an environment variable:
+
+```bash
+export REVENUECAT_API_KEY="your_api_key_here"
+```
+
+Or pass it during build:
+
+```bash
+flutter build ios --dart-define=REVENUECAT_API_KEY=your_api_key_here
+```
+
+### 2. RevenueCat Dashboard Setup
+
+1. Go to [RevenueCat Dashboard](https://app.revenuecat.com/)
+2. Create a new project or select existing one
+3. Configure your app:
+   - **iOS**: Add your App Store Connect API key
+   - **Android**: Add your Google Play Service Account credentials
+   - **macOS**: Add your App Store Connect API key
+
+### 3. Product Configuration
+
+Configure the following product in RevenueCat:
+
+#### Product ID: `lifetime`
+- **Type**: Non-consumable / Lifetime
+- **Description**: Lifetime access to BikeControl full version
+
+### 4. Entitlement Configuration
+
+Create an entitlement in RevenueCat:
+
+#### Entitlement ID: `Full Version`
+- **Products**: Link the `lifetime` product to this entitlement
+
+### 5. Offerings Setup
+
+Create an offering with the lifetime product:
+
+1. Go to **Offerings** in RevenueCat Dashboard
+2. Create a new offering (or use the default)
+3. Add the `lifetime` product to the offering
+4. Mark it as current if desired
+
+## Features
+
+### Implemented Features
+
+1. **RevenueCat SDK Integration**
+   - Automatic initialization with API key from environment
+   - Customer info listener for real-time entitlement updates
+   - Graceful fallback to legacy IAP when RevenueCat key is not available
+
+2. **Entitlement Checking**
+   - Checks for "Full Version" entitlement
+   - Automatically grants/revokes access based on entitlement status
+   - Persistent purchase status storage
+
+3. **Paywall**
+   - Native RevenueCat Paywall UI
+   - Automatically displays available offerings
+   - Handles purchase flow end-to-end
+
+4. **Customer Center**
+   - Access to subscription management
+   - Available when user has purchased
+   - Shown as "Manage" button in IAP status widget
+
+5. **Purchase Restoration**
+   - Restore previous purchases across devices
+   - Automatic entitlement validation
+
+6. **Trial & Command Limits**
+   - Existing trial logic preserved
+   - Daily command limits for free tier
+   - Seamless integration with existing app logic
+
+### Platform Support
+
+- ✅ **iOS**: Full RevenueCat support
+- ✅ **macOS**: Full RevenueCat support
+- ✅ **Android**: Full RevenueCat support
+- ✅ **Windows**: Uses existing Windows IAP service (unchanged)
+- ❌ **Web**: Not supported
+
+## Usage
+
+### For Users
+
+1. **First Launch**: Trial period starts automatically (5 days)
+2. **During Trial**: Full access to all features
+3. **After Trial**: Limited to daily command quota
+4. **Purchase**: Click "Unlock Full Version" to see paywall
+5. **Manage Subscription**: Click "Manage" button (visible after purchase)
+
+### For Developers
+
+#### Initialize RevenueCat
+
+RevenueCat is initialized automatically in `Settings.init()`:
+
+```dart
+await IAPManager.instance.initialize();
+```
+
+#### Check Entitlement
+
+```dart
+if (IAPManager.instance.isPurchased.value) {
+  // User has full version
+}
+```
+
+#### Present Paywall
+
+```dart
+await IAPManager.instance.presentPaywall();
+```
+
+#### Present Customer Center
+
+```dart
+await IAPManager.instance.presentCustomerCenter();
+```
+
+#### Restore Purchases
+
+```dart
+await IAPManager.instance.restorePurchases();
+```
+
+## Testing
+
+### Test Mode
+
+RevenueCat automatically detects sandbox environments:
+
+- **iOS**: Use TestFlight or Xcode sandbox accounts
+- **Android**: Use test tracks in Google Play Console
+- **macOS**: Use Xcode sandbox accounts
+
+### Debug Logs
+
+Debug logs are automatically enabled in debug mode. Check console for:
+
+```
+RevenueCat initialized successfully
+Full Version entitlement: true/false
+```
+
+## Troubleshooting
+
+### API Key Not Found
+
+If you see "RevenueCat API key not configured":
+
+1. Ensure `REVENUECAT_API_KEY` environment variable is set
+2. Or pass via `--dart-define` during build
+3. Check that the key is valid in RevenueCat Dashboard
+
+### Entitlement Not Working
+
+1. Verify product ID matches in:
+   - App Store Connect / Google Play Console
+   - RevenueCat Dashboard
+2. Check that product is linked to "Full Version" entitlement
+3. Verify offering is set as current in RevenueCat
+
+### Paywall Not Showing
+
+1. Ensure offerings are properly configured
+2. Check that at least one product is available
+3. Review RevenueCat Dashboard for configuration errors
+
+## Best Practices
+
+1. **Error Handling**: All RevenueCat calls include proper error handling
+2. **Fallback**: Legacy IAP service is used if RevenueCat key is not available
+3. **Customer Info Listener**: Real-time updates ensure immediate access after purchase
+4. **Platform Separation**: Windows maintains its own IAP implementation
+5. **Security**: API key should never be committed to source code

+      
+      - name: Build Windows
+        run: flutter build windows --release
+```
+
+**Don't forget to add `REVENUECAT_API_KEY` to GitHub Secrets:**
+1. Go to repository **Settings** → **Secrets and variables** → **Actions**
+2. Click **New repository secret**
+3. Name: `REVENUECAT_API_KEY`
+4. Value: Your RevenueCat API key
+
+### GitLab CI
+
+```yaml
+stages:
+  - build
+
+build:ios:
+  stage: build
+  tags:
+    - macos
+  script:
+    - flutter build ios --release --dart-define=REVENUECAT_API_KEY=$REVENUECAT_API_KEY --no-codesign
+  only:
+    - main
+
+build:android:
+  stage: build
+  image: cirrusci/flutter:stable
+  script:
+    - flutter build appbundle --release --dart-define=REVENUECAT_API_KEY=$REVENUECAT_API_KEY
+  only:
+    - main
+```
+
+**Add `REVENUECAT_API_KEY` to GitLab CI/CD Variables:**
+1. Go to project **Settings** → **CI/CD** → **Variables**
+2. Click **Add variable**
+3. Key: `REVENUECAT_API_KEY`
+4. Value: Your RevenueCat API key
+5. Check **Mask variable** and **Protect variable**
+
+### Fastlane
+
+Add to your `Fastfile`:
+
+```ruby
+lane :build_ios do
+  flutter_build(
+    platform: :ios,
+    dart_defines: {
+      "REVENUECAT_API_KEY" => ENV["REVENUECAT_API_KEY"]
+    }
+  )
+end
+
+lane :build_android do
+  flutter_build(
+    platform: :android,
+    dart_defines: {
+      "REVENUECAT_API_KEY" => ENV["REVENUECAT_API_KEY"]
+    }
+  )
+end
+```
+
+## Testing Configurations
+
+### Sandbox Testing (iOS/macOS)
+
+Use a different API key for sandbox testing:
+
+```bash
+# Development/Sandbox builds
+flutter run --dart-define=REVENUECAT_API_KEY=appl_YourSandboxKeyHere
+
+# Production builds
+flutter build ios --dart-define=REVENUECAT_API_KEY=appl_YourProductionKeyHere
+```
+
+### Test Without RevenueCat
+
+To test the fallback to legacy IAP:
+
+```bash
+# Simply don't provide the API key
+flutter run
+
+# Or explicitly unset it
+unset REVENUECAT_API_KEY
+flutter run
+```
+
+The app will automatically use the legacy IAP service.
+
+## Security Best Practices
+
+1. **Never commit API keys to source control**
+   - Add `.env` files to `.gitignore`
+   - Use environment variables or CI/CD secrets
+
+2. **Use different keys for different environments**
+   - Sandbox/Development key for testing
+   - Production key for releases
+
+3. **Rotate keys periodically**
+   - RevenueCat allows generating new keys
+   - Update in all CI/CD pipelines
+
+4. **Limit key permissions**
+   - Use read-only keys where possible
+   - Separate keys for different purposes
+
+## Verifying Configuration
+
+After building with RevenueCat configured, check the logs:
+
+```
+✅ Success indicators:
+- "Using RevenueCat service for IAP"
+- "RevenueCat initialized successfully"
+- Paywall displays when clicking "Unlock Full Version"
+
+❌ Fallback indicators (no key):
+- "Using legacy IAP service (no RevenueCat key)"
+- "RevenueCat API key not configured"
+- Standard purchase dialog instead of paywall
+
+❌ Error indicators:
+- "Failed to initialize RevenueCat"
+- Check API key is correct
+- Verify network connectivity
+- Check RevenueCat Dashboard configuration
+```
+
+## Troubleshooting
+
+### "API key not configured" in logs
+
+**Cause**: Environment variable or dart-define not set correctly
+
+**Solution**:
+```bash
+# Verify key is set
+echo $REVENUECAT_API_KEY
+
+# If empty, set it
+export REVENUECAT_API_KEY="your_key_here"
+
+# Or use dart-define
+flutter run --dart-define=REVENUECAT_API_KEY=your_key_here
+```
+
+### Key works locally but not in CI/CD
+
+**Cause**: Secret not configured or not accessible
+
+**Solution**:
+1. Verify secret is added to CI/CD platform
+2. Check secret name matches exactly
+3. Ensure job has permission to access secrets
+4. Check if running on forked repository (secrets may not be available)
+
+### Different behavior in release vs debug
+
+**Cause**: Different API keys or missing configuration in release build
+
+**Solution**:
+- Ensure `--dart-define` is included in release build command
+- Verify production API key is correct
+- Check RevenueCat Dashboard for production vs sandbox configuration

+# RevenueCat Setup Instructions
+
+## Quick Start Guide
+
+### Step 1: Get Your RevenueCat API Key
+
+1. Sign up at [RevenueCat](https://app.revenuecat.com/)
+2. Create a new project
+3. Go to **Settings** → **API Keys**
+4. Copy your API key (starts with `appl_` or similar)
+
+### Step 2: Configure Products in App Store Connect / Google Play Console
+
+#### For iOS/macOS:
+1. Go to [App Store Connect](https://appstoreconnect.apple.com/)
+2. Select your app → **In-App Purchases**
+3. Create a new In-App Purchase:
+   - **Type**: Non-Consumable
+   - **Product ID**: `lifetime`
+   - **Display Name**: BikeControl Lifetime
+   - **Description**: Lifetime access to all BikeControl features
+   - **Price**: Set your desired price
+
+#### For Android:
+1. Go to [Google Play Console](https://play.google.com/console/)
+2. Select your app → **Monetize** → **In-app products**
+3. Create a new product:
+   - **Product ID**: `lifetime`
+   - **Name**: BikeControl Lifetime
+   - **Description**: Lifetime access to all BikeControl features
+   - **Price**: Set your desired price
+
+### Step 3: Configure RevenueCat Dashboard
+
+1. Add your app to RevenueCat:
+   - **iOS/macOS**: Add App Store Connect credentials
+   - **Android**: Add Google Play Service Account JSON
+
+2. Create Products:
+   - Go to **Products**
+   - Click **Add Product**
+   - Enter Product ID: `lifetime`
+   - Link to App Store / Google Play product
+
+3. Create Entitlement:
+   - Go to **Entitlements**
+   - Create new entitlement: `Full Version`
+   - Add the `lifetime` product to this entitlement
+
+4. Create Offering:
+   - Go to **Offerings**
+   - Create or edit the default offering
+   - Add `lifetime` product
+   - Set as current offering
+
+### Step 4: Configure Your Build
+
+Add your RevenueCat API key to your build:
+
+#### Option A: Environment Variable (Development)
+```bash
+export REVENUECAT_API_KEY="your_api_key_here"
+flutter run
+```
+
+#### Option B: Build Command (Production)
+```bash
+flutter build ios --dart-define=REVENUECAT_API_KEY=your_api_key_here
+flutter build apk --dart-define=REVENUECAT_API_KEY=your_api_key_here
+flutter build macos --dart-define=REVENUECAT_API_KEY=your_api_key_here
+```
+
+#### Option C: CI/CD (Recommended)
+Add `REVENUECAT_API_KEY` as a secret in your CI/CD environment:
+
+**GitHub Actions:**
+```yaml
+- name: Build
+  env:
+    REVENUECAT_API_KEY: ${{ secrets.REVENUECAT_API_KEY }}
+  run: flutter build ios --dart-define=REVENUECAT_API_KEY=$REVENUECAT_API_KEY
+```
+
+### Step 5: Test Your Integration
+
+1. **Build and Run**: Build your app with the API key configured
+2. **Check Logs**: Look for "RevenueCat initialized successfully"
+3. **Test Purchase Flow**:
+   - Click "Unlock Full Version"
+   - Should see RevenueCat paywall
+   - Complete test purchase (use sandbox/test account)
+4. **Verify Entitlement**: After purchase, should see "Full Version" status
+5. **Test Customer Center**: Click "Manage" button when purchased
+
+### Step 6: Production Checklist
+
+- [ ] RevenueCat project created and configured
+- [ ] Products created in App Store Connect / Google Play Console
+- [ ] Products imported to RevenueCat
+- [ ] "Full Version" entitlement created and linked to `lifetime` product
+- [ ] Offering created with `lifetime` product
+- [ ] API key added to CI/CD secrets
+- [ ] Test purchase completed successfully
+- [ ] Sandbox testing completed
+- [ ] Production testing completed (TestFlight / Internal Testing)
+
+## Important Notes
+
+1. **Never commit your API key** to source control
+2. **Use sandbox accounts** for testing
+3. **Product IDs must match** across App Store/Google Play and RevenueCat
+4. **Entitlement name** must be exactly `Full Version`
+5. **Windows users** will continue to use Windows Store IAP
+
+## Fallback Behavior
+
+If RevenueCat API key is not configured:
+- App will automatically use legacy IAP service
+- All features will continue to work
+- iOS/macOS will use `in_app_purchase` package
+- Android will use `in_app_purchase` package
+- Windows will use `windows_iap` package
+
+## Support
+
+For issues with:
+- **RevenueCat SDK**: Check [RevenueCat Docs](https://www.revenuecat.com/docs)
+- **Product Setup**: Review platform-specific documentation

+# RevenueCat Integration - Implementation Summary
+
+## Overview
+
+This integration adds RevenueCat SDK support to BikeControl for iOS, macOS, and Android platforms while preserving the existing Windows IAP implementation. The implementation uses a flexible architecture that:
+
+1. **Automatically switches** between RevenueCat and legacy IAP based on API key availability
+2. **Preserves Windows logic** completely (no changes to windows_iap)
+3. **Maintains backward compatibility** with all existing features
+4. **Uses dependency injection** to avoid circular dependencies
+5. **Follows best practices** for error handling and async operations
+
+## What Was Changed
+
+### New Files
+
+1. **`lib/utils/iap/revenuecat_service.dart`** (336 lines)
+   - Complete RevenueCat integration
+   - Entitlement checking for "Full Version"
+   - Customer info management
+   - Paywall presentation
+   - Customer Center presentation
+   - Trial and command limit logic
+   - Uses callbacks to avoid circular dependencies
+
+2. **`REVENUECAT_INTEGRATION.md`** (223 lines)
+   - Technical integration documentation
+   - Feature list
+   - Usage examples
+   - Testing guidelines
+   - Troubleshooting guide
+
+3. **`REVENUECAT_SETUP.md`** (148 lines)
+   - Quick start guide
+   - Step-by-step setup instructions
+   - Product configuration
+   - Dashboard setup
+   - Production checklist
+
+4. **`REVENUECAT_CONFIG_EXAMPLES.md`** (294 lines)
+   - Build configuration examples
+   - CI/CD integration examples
+   - Development environment setup
+   - Testing configurations
+
+### Modified Files
+
+1. **`pubspec.yaml`**
+   - Added `purchases_flutter: ^8.2.2`
+   - Added `purchases_ui_flutter: ^8.2.2`
+
+2. **`lib/utils/iap/iap_manager.dart`**
+   - Added RevenueCatService support
+   - Automatic service selection based on API key
+   - New methods: `presentPaywall()`, `presentCustomerCenter()`, `isUsingRevenueCat`
+   - Updated to use callbacks for RevenueCatService
+   - Made reset() async
+
+3. **`lib/utils/iap/iap_service.dart`**
+   - Made reset() async for consistency
+
+4. **`lib/widgets/iap_status_widget.dart`**
+   - Added "Manage" button for Customer Center (when purchased)
+   - Updated purchase flow to use paywall when RevenueCat is available
+
+## How It Works
+
+### Initialization Flow
+
+```
+1. App starts → Settings.init()
+2. Settings calls IAPManager.instance.initialize()
+3. IAPManager checks platform:
+   - Windows → Use WindowsIAPService
+   - iOS/macOS/Android with REVENUECAT_API_KEY → Use RevenueCatService
+   - iOS/macOS/Android without key → Use legacy IAPService (fallback)
+4. Service initializes and checks entitlements
+5. isPurchased ValueNotifier updated
+6. UI reacts to changes
+```
+
+### Purchase Flow
+
+**With RevenueCat:**
+```
+User clicks "Unlock Full Version"
+  ↓
+IAPManager.presentPaywall()
+  ↓
+RevenueCatUI.presentPaywall()
+  ↓
+Native paywall shows with configured offerings
+  ↓
+User completes purchase
+  ↓
+CustomerInfo listener triggered
+  ↓
+isPurchased updated automatically
+  ↓
+UI updates to show "Full Version"
+```
+
+**Without RevenueCat (Fallback):**
+```
+User clicks "Unlock Full Version"
+  ↓
+IAPManager.purchaseFullVersion()
+  ↓
+Legacy IAP flow (in_app_purchase package)
+  ↓
+Purchase completed
+  ↓
+Manual isPurchased update
+  ↓
+UI updates
+```
+
+### Architecture Highlights
+
+1. **No Circular Dependencies**
+   - RevenueCatService receives callbacks from IAPManager
+   - Uses `isPurchasedNotifier`, `getDailyCommandLimit()`, `setDailyCommandLimit()`
+   - Clean separation of concerns
+
+2. **Graceful Degradation**
+   - If RevenueCat API key not set → Falls back to legacy IAP
+   - If RevenueCat initialization fails → Falls back to legacy IAP
+   - If RevenueCat not available on platform → Uses appropriate service
+
+3. **Platform-Specific Handling**
+   - Windows: Always uses WindowsIAPService (unchanged)
+   - iOS/macOS/Android: Uses RevenueCat when configured, otherwise legacy
+   - Web: No IAP support (as before)
+
+## Configuration Requirements
+
+### Required Environment Variable
+
+```bash
+REVENUECAT_API_KEY=appl_YourKeyHere
+```
+
+Set via:
+- Environment variable: `export REVENUECAT_API_KEY=...`
+- Build flag: `--dart-define=REVENUECAT_API_KEY=...`
+- CI/CD secret: Add to GitHub Actions, GitLab CI, etc.
+
+### RevenueCat Dashboard Setup
+
+1. Create project in RevenueCat
+2. Add app (iOS/Android/macOS)
+3. Configure products:
+   - Product ID: `lifetime` (non-consumable)
+4. Create entitlement:
+   - Entitlement ID: `Full Version`
+   - Link `lifetime` product
+5. Create offering:
+   - Add `lifetime` product
+   - Set as current
+
+### Store Setup
+
+**iOS/macOS (App Store Connect):**
+- Create in-app purchase: `lifetime`
+- Type: Non-Consumable
+- Link to RevenueCat
+
+**Android (Google Play Console):**
+- Create product: `lifetime`
+- Type: One-time purchase
+- Link to RevenueCat
+
+## Testing
+
+### Unit Testing
+
+No new unit tests added as:
+1. Existing test infrastructure is minimal
+2. Integration testing more valuable for IAP
+3. RevenueCat has its own test mode
+
+### Manual Testing Steps
+
+1. **Without API Key (Fallback)**
+   ```bash
+   flutter run
+   # Should see: "Using legacy IAP service (no RevenueCat key)"
+   # Purchase flow uses legacy in_app_purchase
+   ```
+
+2. **With API Key (RevenueCat)**
+   ```bash
+   flutter run --dart-define=REVENUECAT_API_KEY=your_key
+   # Should see: "Using RevenueCat service for IAP"
+   # Should see: "RevenueCat initialized successfully"
+   # Purchase flow uses RevenueCat paywall
+   ```
+
+3. **Windows (Unchanged)**
+   ```bash
+   flutter run -d windows
+   # Should use WindowsIAPService as before
+   # No RevenueCat involved
+   ```
+
+4. **Customer Center**
+   - Purchase full version
+   - Click "Manage" button
+   - Should open Customer Center UI
+
+## Security Considerations
+
+1. **API Key Protection**
+   - Never committed to source control
+   - Passed via environment or build flags
+   - Stored in CI/CD secrets only
+
+2. **Error Messages**
+   - No sensitive information exposed
+   - Generic error messages for users
+   - Detailed logs only in debug mode
+
+3. **Entitlement Validation**
+   - Server-side validation by RevenueCat
+   - Real-time updates via listener
+   - Local caching with periodic checks
+
+## Performance Impact
+
+- **Minimal**: RevenueCat SDK is lightweight
+- **Lazy Loading**: Only initialized when needed
+- **Async Operations**: All I/O operations are async
+- **No Blocking**: UI remains responsive during purchases
+
+## Future Enhancements
+
+Potential improvements for future PRs:
+
+1. **Subscription Support**
+   - Add recurring subscription products
+   - Handle subscription status changes
+   - Show subscription expiry dates
+
+2. **Promotional Offers**
+   - Implement iOS promotional offers
+   - Add Android promo codes support
+
+3. **Analytics Integration**
+   - Track purchase events
+   - Monitor trial conversion rates
+   - A/B test different offerings
+
+4. **Multi-Product Support**
+   - Add more product tiers
+   - Feature-specific purchases
+   - Add-on products
+
+## Migration Guide
+
+For existing users with legacy IAP:
+
+1. **No Action Required**
+   - Existing purchases are preserved
+   - Trial state is maintained
+   - Command limits unchanged
+
+2. **When RevenueCat Enabled**
+   - Previous purchases recognized via receipt validation
+   - Entitlement granted if applicable
+   - Seamless transition for users
+
+## Support
+
+For issues:
+- RevenueCat SDK: https://www.revenuecat.com/docs
+- BikeControl Integration: See REVENUECAT_INTEGRATION.md
+- Setup Help: See REVENUECAT_SETUP.md
+- Configuration Examples: See REVENUECAT_CONFIG_EXAMPLES.md
+
+## Conclusion
+
+This integration provides a modern, flexible subscription management solution while maintaining full backward compatibility. The architecture allows BikeControl to leverage RevenueCat's powerful features when available while gracefully falling back to legacy systems when needed.
+
+Key achievements:
+✅ Zero breaking changes
+✅ Platform-specific optimization (Windows untouched)
+✅ Clean architecture (no circular dependencies)
+✅ Comprehensive documentation
+✅ Production-ready error handling
+✅ Secure API key management
+✅ Full feature parity with legacy system
+✅ Enhanced features (Paywall, Customer Center)

+# Future Improvements for RevenueCat Integration
+
+This document tracks potential improvements for the RevenueCat integration that are not critical but would enhance code quality and maintainability.
+
+## Code Quality Enhancements
+
+### 1. Dependency Injection Consistency
+
+**Current State:** The RevenueCatService uses callbacks for some values but direct access for others.
+
+**Issue:** 
+- Uses `getDailyCommandLimit()` callback ✅
+- Uses `isPurchasedNotifier.value` directly ⚠️
+- Checks `isTrialExpired` and `Platform.isAndroid` directly ⚠️
+
+**Proposed Improvement:**
+```dart
+// Add more callbacks for complete DI pattern
+RevenueCatService(
+  this._prefs, {
+  required this.isPurchasedNotifier,
+  required this.getDailyCommandLimit,
+  required this.setDailyCommandLimit,
+  required this.isAndroid,  // NEW
+});
+```
+
+**Priority:** Low - Current implementation works correctly
+
+**Effort:** Medium - Would require refactoring constructor and call sites
+
+---
+
+### 2. Magic Number for Android Command Limit
+
+**Current State:**
+```dart
+if (!isTrialExpired && Platform.isAndroid) {
+  setDailyCommandLimit(80);  // Hardcoded value
+}
+```
+
+**Issue:** The value `80` is hardcoded without explanation.
+
+**Proposed Improvement:**
+```dart
+// In RevenueCatService
+static const int androidTrialCommandLimit = 80;
+
+// Usage
+if (!isTrialExpired && Platform.isAndroid) {
+  setDailyCommandLimit(androidTrialCommandLimit);
+}
+```
+
+**Priority:** Low - Value is only used once, well-documented in context
+
+**Effort:** Trivial - Just extract to constant
+
+---
+
+### 3. Platform Detection Abstraction
+
+**Current State:**
+```dart
+if (!isTrialExpired && Platform.isAndroid) {
+  // Android-specific logic
+}
+```
+
+**Issue:** Direct platform checks could be abstracted for testability.
+
+**Proposed Improvement:**
+```dart
+// Pass platform info through DI
+final bool isAndroidPlatform;
+
+RevenueCatService(
+  this._prefs, {
+  // ... other params
+  this.isAndroidPlatform = kIsAndroid,  // Can be mocked in tests
+});
+```
+
+**Priority:** Very Low - Current approach is standard for Flutter
+
+**Effort:** Low - Simple parameter addition
+
+---
+
+## Feature Enhancements
+
+### 4. Subscription Support
+
+**Current State:** Only supports lifetime (non-consumable) purchases.
+
+**Proposed Addition:**
+- Monthly subscriptions
+- Annual subscriptions
+- Subscription status tracking
+- Expiration handling
+
+**Priority:** Medium - Depends on business requirements
+
+**Effort:** High - Requires:
+- RevenueCat offering configuration
+- UI updates for subscription display
+- Subscription renewal handling
+- Cancellation support
+
+---
+
+### 5. Analytics Integration
+
+**Current State:** No purchase analytics beyond logs.
+
+**Proposed Addition:**
+- Track purchase attempts
+- Monitor conversion rates
+- A/B test different offerings
+- Revenue analytics
+
+**Priority:** Low - Nice to have for business insights
+
+**Effort:** Medium - Requires analytics SDK integration
+
+---
+
+### 6. Promotional Offers
+
+**Current State:** No promotional offer support.
+
+**Proposed Addition:**
+- iOS promotional offers
+- Android promo codes
+- Limited-time discounts
+- First-purchase incentives
+
+**Priority:** Low - Marketing feature
+
+**Effort:** Medium - RevenueCat SDK supports this
+
+---
+
+## Testing Improvements
+
+### 7. Unit Tests for RevenueCat Service
+
+**Current State:** No unit tests for RevenueCat integration.
+
+**Proposed Addition:**
+```dart
+test('RevenueCatService initializes with valid API key', () async {
+  // Mock RevenueCat SDK
+  // Verify initialization
+});
+
+test('RevenueCatService falls back gracefully without API key', () async {
+  // Verify fallback behavior
+});
+```
+
+**Priority:** Medium - Would improve confidence in changes
+
+**Effort:** High - Requires mocking RevenueCat SDK
+
+---
+
+### 8. Integration Tests
+
+**Current State:** Manual testing only.
+
+**Proposed Addition:**
+- Automated purchase flow tests
+- Entitlement checking tests
+- Paywall presentation tests
+- Customer Center tests
+
+**Priority:** Medium - Would catch regressions
+
+**Effort:** Very High - Requires test environment setup
+
+---
+
+## Documentation Enhancements
+
+### 9. Video Tutorial
+
+**Current State:** Text documentation only.
+
+**Proposed Addition:**
+- Setup walkthrough video
+- RevenueCat dashboard configuration video
+- Build configuration demonstration
+
+**Priority:** Low - Text docs are comprehensive
+
+**Effort:** Medium - Recording and editing
+
+---
+
+### 10. Troubleshooting Flowchart
+
+**Current State:** Text-based troubleshooting.
+
+**Proposed Addition:**
+- Visual decision tree for common issues
+- Error code reference
+- Quick diagnosis guide
+
+**Priority:** Very Low - Current docs are clear
+
+**Effort:** Low - Create diagram
+
+---
+
+## Implementation Priority
+
+### High Priority (Do Soon)
+- None currently - all critical issues resolved
+
+### Medium Priority (Consider for Next Sprint)
+- Unit tests (#7)
+- Subscription support (#4) - if business needs it
+
+### Low Priority (Backlog)
+- Extract magic number (#2) - trivial, do if touching that code
+- Analytics integration (#5) - if product team requests
+- Dependency injection consistency (#1) - only if refactoring for other reasons
+
+### Very Low Priority (Optional)
+- Platform detection abstraction (#3)
+- Promotional offers (#6)
+- Video tutorial (#9)
+- Troubleshooting flowchart (#10)
+- Integration tests (#8) - high effort, moderate value
+
+---
+
+## Notes
+
+- Current implementation is **production-ready** as-is
+- These improvements are **optional enhancements**
+- Prioritize based on actual business/technical needs
+- Don't optimize prematurely - wait for real pain points
+
+## Decision Log
+
+**Why not implement these now?**
+
+1. **Time constraints** - Minimal change requirement
+2. **Working implementation** - No critical issues
+3. **YAGNI principle** - Don't add complexity until needed
+4. **Maintainability** - Simpler code is easier to maintain
+5. **Testing** - Manual testing sufficient for initial release
+
+**When to revisit?**
+
+- If adding subscriptions → Do #4, #5
+- If testing becomes pain point → Do #7, #8  
+- If code becomes hard to maintain → Do #1, #2, #3
+- If users need help → Do #9, #10
+- If new promotional campaigns → Do #6

-# Future Improvements for RevenueCat Integration
-
-This document tracks potential improvements for the RevenueCat integration that are not critical but would enhance code quality and maintainability.
-
-## Code Quality Enhancements
-
-### 1. Dependency Injection Consistency
-
-**Current State:** The RevenueCatService uses callbacks for some values but direct access for others.
-
-**Issue:** 
-- Uses `getDailyCommandLimit()` callback ✅
-- Uses `isPurchasedNotifier.value` directly ⚠️
-- Checks `isTrialExpired` and `Platform.isAndroid` directly ⚠️
-
-**Proposed Improvement:**
-```dart
-// Add more callbacks for complete DI pattern
-RevenueCatService(
-  this._prefs, {
-  required this.isPurchasedNotifier,
-  required this.getDailyCommandLimit,
-  required this.setDailyCommandLimit,
-  required this.isAndroid,  // NEW
-});
-```
-
-**Priority:** Low - Current implementation works correctly
-
-**Effort:** Medium - Would require refactoring constructor and call sites
-
----
-
-### 2. Magic Number for Android Command Limit
-
-**Current State:**
-```dart
-if (!isTrialExpired && Platform.isAndroid) {
-  setDailyCommandLimit(80);  // Hardcoded value
-}
-```
-
-**Issue:** The value `80` is hardcoded without explanation.
-
-**Proposed Improvement:**
-```dart
-// In RevenueCatService
-static const int androidTrialCommandLimit = 80;
-
-// Usage
-if (!isTrialExpired && Platform.isAndroid) {
-  setDailyCommandLimit(androidTrialCommandLimit);
-}
-```
-
-**Priority:** Low - Value is only used once, well-documented in context
-
-**Effort:** Trivial - Just extract to constant
-
----
-
-### 3. Platform Detection Abstraction
-
-**Current State:**
-```dart
-if (!isTrialExpired && Platform.isAndroid) {
-  // Android-specific logic
-}
-```
-
-**Issue:** Direct platform checks could be abstracted for testability.
-
-**Proposed Improvement:**
-```dart
-// Pass platform info through DI
-final bool isAndroidPlatform;
-
-RevenueCatService(
-  this._prefs, {
-  // ... other params
-  this.isAndroidPlatform = kIsAndroid,  // Can be mocked in tests
-});
-```
-
-**Priority:** Very Low - Current approach is standard for Flutter
-
-**Effort:** Low - Simple parameter addition
-
----
-
-## Feature Enhancements
-
-### 4. Subscription Support
-
-**Current State:** Only supports lifetime (non-consumable) purchases.
-
-**Proposed Addition:**
-- Monthly subscriptions
-- Annual subscriptions
-- Subscription status tracking
-- Expiration handling
-
-**Priority:** Medium - Depends on business requirements
-
-**Effort:** High - Requires:
-- RevenueCat offering configuration
-- UI updates for subscription display
-- Subscription renewal handling
-- Cancellation support
-
----
-
-### 5. Analytics Integration
-
-**Current State:** No purchase analytics beyond logs.
-
-**Proposed Addition:**
-- Track purchase attempts
-- Monitor conversion rates
-- A/B test different offerings
-- Revenue analytics
-
-**Priority:** Low - Nice to have for business insights
-
-**Effort:** Medium - Requires analytics SDK integration
-
----
-
-### 6. Promotional Offers
-
-**Current State:** No promotional offer support.
-
-**Proposed Addition:**
-- iOS promotional offers
-- Android promo codes
-- Limited-time discounts
-- First-purchase incentives
-
-**Priority:** Low - Marketing feature
-
-**Effort:** Medium - RevenueCat SDK supports this
-
----
-
-## Testing Improvements
-
-### 7. Unit Tests for RevenueCat Service
-
-**Current State:** No unit tests for RevenueCat integration.
-
-**Proposed Addition:**
-```dart
-test('RevenueCatService initializes with valid API key', () async {
-  // Mock RevenueCat SDK
-  // Verify initialization
-});
-
-test('RevenueCatService falls back gracefully without API key', () async {
-  // Verify fallback behavior
-});
-```
-
-**Priority:** Medium - Would improve confidence in changes
-
-**Effort:** High - Requires mocking RevenueCat SDK
-
----
-
-### 8. Integration Tests
-
-**Current State:** Manual testing only.
-
-**Proposed Addition:**
-- Automated purchase flow tests
-- Entitlement checking tests
-- Paywall presentation tests
-- Customer Center tests
-
-**Priority:** Medium - Would catch regressions
-
-**Effort:** Very High - Requires test environment setup
-
----
-
-## Documentation Enhancements
-
-### 9. Video Tutorial
-
-**Current State:** Text documentation only.
-
-**Proposed Addition:**
-- Setup walkthrough video
-- RevenueCat dashboard configuration video
-- Build configuration demonstration
-
-**Priority:** Low - Text docs are comprehensive
-
-**Effort:** Medium - Recording and editing
-
----
-
-### 10. Troubleshooting Flowchart
-
-**Current State:** Text-based troubleshooting.
-
-**Proposed Addition:**
-- Visual decision tree for common issues
-- Error code reference
-- Quick diagnosis guide
-
-**Priority:** Very Low - Current docs are clear
-
-**Effort:** Low - Create diagram
-
----
-
-## Implementation Priority
-
-### High Priority (Do Soon)
-- None currently - all critical issues resolved
-
-### Medium Priority (Consider for Next Sprint)
-- Unit tests (#7)
-- Subscription support (#4) - if business needs it
-
-### Low Priority (Backlog)
-- Extract magic number (#2) - trivial, do if touching that code
-- Analytics integration (#5) - if product team requests
-- Dependency injection consistency (#1) - only if refactoring for other reasons
-
-### Very Low Priority (Optional)
-- Platform detection abstraction (#3)
-- Promotional offers (#6)
-- Video tutorial (#9)
-- Troubleshooting flowchart (#10)
-- Integration tests (#8) - high effort, moderate value
-
----
-
-## Notes
-
-- Current implementation is **production-ready** as-is
-- These improvements are **optional enhancements**
-- Prioritize based on actual business/technical needs
-- Don't optimize prematurely - wait for real pain points
-
-## Decision Log
-
-**Why not implement these now?**
-
-1. **Time constraints** - Minimal change requirement
-2. **Working implementation** - No critical issues
-3. **YAGNI principle** - Don't add complexity until needed
-4. **Maintainability** - Simpler code is easier to maintain
-5. **Testing** - Manual testing sufficient for initial release
-
-**When to revisit?**
-
-- If adding subscriptions → Do #4, #5
-- If testing becomes pain point → Do #7, #8  
-- If code becomes hard to maintain → Do #1, #2, #3
-- If users need help → Do #9, #10
-- If new promotional campaigns → Do #6

-# RevenueCat Integration - Implementation Summary
-
-## Overview
-
-This integration adds RevenueCat SDK support to BikeControl for iOS, macOS, and Android platforms while preserving the existing Windows IAP implementation. The implementation uses a flexible architecture that:
-
-1. **Automatically switches** between RevenueCat and legacy IAP based on API key availability
-2. **Preserves Windows logic** completely (no changes to windows_iap)
-3. **Maintains backward compatibility** with all existing features
-4. **Uses dependency injection** to avoid circular dependencies
-5. **Follows best practices** for error handling and async operations
-

-
-### Modified Files
-
-1. **`pubspec.yaml`**
-   - Added `purchases_flutter: ^8.2.2`
-   - Added `purchases_ui_flutter: ^8.2.2`
-
-2. **`lib/utils/iap/iap_manager.dart`**
-   - Added RevenueCatService support
-   - Automatic service selection based on API key
-   - New methods: `presentPaywall()`, `presentCustomerCenter()`, `isUsingRevenueCat`
-   - Updated to use callbacks for RevenueCatService
-   - Made reset() async
-
-3. **`lib/utils/iap/iap_service.dart`**
-   - Made reset() async for consistency
-
-4. **`lib/widgets/iap_status_widget.dart`**
-   - Added "Manage" button for Customer Center (when purchased)
-   - Updated purchase flow to use paywall when RevenueCat is available
-
-## How It Works
-
-### Initialization Flow
-
-```
-1. App starts → Settings.init()
-2. Settings calls IAPManager.instance.initialize()
-3. IAPManager checks platform:
-   - Windows → Use WindowsIAPService
-   - iOS/macOS/Android with REVENUECAT_API_KEY → Use RevenueCatService
-   - iOS/macOS/Android without key → Use legacy IAPService (fallback)
-4. Service initializes and checks entitlements
-5. isPurchased ValueNotifier updated
-6. UI reacts to changes
-```
-
-### Purchase Flow
-
-**With RevenueCat:**
-```
-User clicks "Unlock Full Version"
-  ↓
-IAPManager.presentPaywall()
-  ↓
-RevenueCatUI.presentPaywall()
-  ↓
-Native paywall shows with configured offerings
-  ↓
-User completes purchase
-  ↓
-CustomerInfo listener triggered
-  ↓
-isPurchased updated automatically
-  ↓
-UI updates to show "Full Version"
-```
-
-**Without RevenueCat (Fallback):**
-```
-User clicks "Unlock Full Version"
-  ↓
-IAPManager.purchaseFullVersion()
-  ↓
-Legacy IAP flow (in_app_purchase package)
-  ↓
-Purchase completed
-  ↓
-Manual isPurchased update
-  ↓
-UI updates
-```
-
-### Architecture Highlights
-
-1. **No Circular Dependencies**
-   - RevenueCatService receives callbacks from IAPManager
-   - Uses `isPurchasedNotifier`, `getDailyCommandLimit()`, `setDailyCommandLimit()`
-   - Clean separation of concerns
-
-2. **Graceful Degradation**
-   - If RevenueCat API key not set → Falls back to legacy IAP
-   - If RevenueCat initialization fails → Falls back to legacy IAP
-   - If RevenueCat not available on platform → Uses appropriate service
-
-3. **Platform-Specific Handling**
-   - Windows: Always uses WindowsIAPService (unchanged)
-   - iOS/macOS/Android: Uses RevenueCat when configured, otherwise legacy
-   - Web: No IAP support (as before)
-
-## Configuration Requirements
-
-### Required Environment Variable
-
-```bash
-REVENUECAT_API_KEY=appl_YourKeyHere
-```
-
-Set via:
-- Environment variable: `export REVENUECAT_API_KEY=...`
-- Build flag: `--dart-define=REVENUECAT_API_KEY=...`
-- CI/CD secret: Add to GitHub Actions, GitLab CI, etc.
-
-### RevenueCat Dashboard Setup
-
-1. Create project in RevenueCat
-2. Add app (iOS/Android/macOS)
-3. Configure products:
-   - Product ID: `lifetime` (non-consumable)
-4. Create entitlement:
-   - Entitlement ID: `Full Version`
-   - Link `lifetime` product
-5. Create offering:
-   - Add `lifetime` product
-   - Set as current
-
-### Store Setup
-
-**iOS/macOS (App Store Connect):**
-- Create in-app purchase: `lifetime`
-- Type: Non-Consumable
-- Link to RevenueCat
-
-**Android (Google Play Console):**
-- Create product: `lifetime`
-- Type: One-time purchase
-- Link to RevenueCat
-
-## Testing
-
-### Unit Testing
-
-No new unit tests added as:
-1. Existing test infrastructure is minimal
-2. Integration testing more valuable for IAP
-3. RevenueCat has its own test mode
-
-### Manual Testing Steps
-
-1. **Without API Key (Fallback)**
-   ```bash
-   flutter run
-   # Should see: "Using legacy IAP service (no RevenueCat key)"
-   # Purchase flow uses legacy in_app_purchase
-   ```
-
-2. **With API Key (RevenueCat)**
-   ```bash
-   flutter run --dart-define=REVENUECAT_API_KEY=your_key
-   # Should see: "Using RevenueCat service for IAP"
-   # Should see: "RevenueCat initialized successfully"
-   # Purchase flow uses RevenueCat paywall
-   ```
-
-3. **Windows (Unchanged)**
-   ```bash
-   flutter run -d windows
-   # Should use WindowsIAPService as before
-   # No RevenueCat involved
-   ```
-
-4. **Customer Center**
-   - Purchase full version
-   - Click "Manage" button
-   - Should open Customer Center UI
-
-## Security Considerations
-
-1. **API Key Protection**
-   - Never committed to source control
-   - Passed via environment or build flags
-   - Stored in CI/CD secrets only
-
-2. **Error Messages**
-   - No sensitive information exposed
-   - Generic error messages for users
-   - Detailed logs only in debug mode
-
-3. **Entitlement Validation**
-   - Server-side validation by RevenueCat
-   - Real-time updates via listener
-   - Local caching with periodic checks
-
-## Performance Impact
-
-- **Minimal**: RevenueCat SDK is lightweight
-- **Lazy Loading**: Only initialized when needed
-- **Async Operations**: All I/O operations are async
-- **No Blocking**: UI remains responsive during purchases
-
-## Future Enhancements
-
-Potential improvements for future PRs:
-
-1. **Subscription Support**
-   - Add recurring subscription products
-   - Handle subscription status changes
-   - Show subscription expiry dates
-
-2. **Promotional Offers**
-   - Implement iOS promotional offers
-   - Add Android promo codes support
-
-3. **Analytics Integration**
-   - Track purchase events
-   - Monitor trial conversion rates
-   - A/B test different offerings
-
-4. **Multi-Product Support**
-   - Add more product tiers
-   - Feature-specific purchases
-   - Add-on products
-
-## Migration Guide
-
-For existing users with legacy IAP:
-
-1. **No Action Required**
-   - Existing purchases are preserved
-   - Trial state is maintained
-   - Command limits unchanged
-
-2. **When RevenueCat Enabled**
-   - Previous purchases recognized via receipt validation
-   - Entitlement granted if applicable
-   - Seamless transition for users
-

-
-## Conclusion
-
-This integration provides a modern, flexible subscription management solution while maintaining full backward compatibility. The architecture allows BikeControl to leverage RevenueCat's powerful features when available while gracefully falling back to legacy systems when needed.
-

-  image: cirrusci/flutter:stable
-  script:
-    - flutter build appbundle --release --dart-define=REVENUECAT_API_KEY=$REVENUECAT_API_KEY
-  only:
-    - main
-```
-
-**Add `REVENUECAT_API_KEY` to GitLab CI/CD Variables:**
-1. Go to project **Settings** → **CI/CD** → **Variables**
-2. Click **Add variable**
-3. Key: `REVENUECAT_API_KEY`
-4. Value: Your RevenueCat API key
-5. Check **Mask variable** and **Protect variable**
-
-### Fastlane
-
-Add to your `Fastfile`:
-
-```ruby
-lane :build_ios do
-  flutter_build(
-    platform: :ios,
-    dart_defines: {
-      "REVENUECAT_API_KEY" => ENV["REVENUECAT_API_KEY"]
-    }
-  )
-end
-
-lane :build_android do
-  flutter_build(
-    platform: :android,
-    dart_defines: {
-      "REVENUECAT_API_KEY" => ENV["REVENUECAT_API_KEY"]
-    }
-  )
-end
-```
-
-## Testing Configurations
-
-### Sandbox Testing (iOS/macOS)
-
-Use a different API key for sandbox testing:
-
-```bash
-# Development/Sandbox builds
-flutter run --dart-define=REVENUECAT_API_KEY=appl_YourSandboxKeyHere
-
-# Production builds
-flutter build ios --dart-define=REVENUECAT_API_KEY=appl_YourProductionKeyHere
-```
-
-### Test Without RevenueCat
-
-To test the fallback to legacy IAP:
-
-```bash
-# Simply don't provide the API key
-flutter run
-
-# Or explicitly unset it
-unset REVENUECAT_API_KEY
-flutter run
-```
-
-The app will automatically use the legacy IAP service.
-
-## Security Best Practices
-
-1. **Never commit API keys to source control**
-   - Add `.env` files to `.gitignore`
-   - Use environment variables or CI/CD secrets
-
-2. **Use different keys for different environments**
-   - Sandbox/Development key for testing
-   - Production key for releases
-
-3. **Rotate keys periodically**
-   - RevenueCat allows generating new keys
-   - Update in all CI/CD pipelines
-
-4. **Limit key permissions**
-   - Use read-only keys where possible
-   - Separate keys for different purposes
-
-## Verifying Configuration
-
-After building with RevenueCat configured, check the logs:
-
-```
-✅ Success indicators:
-- "Using RevenueCat service for IAP"
-- "RevenueCat initialized successfully"
-- Paywall displays when clicking "Unlock Full Version"
-
-❌ Fallback indicators (no key):
-- "Using legacy IAP service (no RevenueCat key)"
-- "RevenueCat API key not configured"
-- Standard purchase dialog instead of paywall
-
-❌ Error indicators:
-- "Failed to initialize RevenueCat"
-- Check API key is correct
-- Verify network connectivity
-- Check RevenueCat Dashboard configuration
-```
-
-## Troubleshooting
-
-### "API key not configured" in logs
-
-**Cause**: Environment variable or dart-define not set correctly
-
-**Solution**:
-```bash
-# Verify key is set
-echo $REVENUECAT_API_KEY
-
-# If empty, set it
-export REVENUECAT_API_KEY="your_key_here"
-
-# Or use dart-define
-flutter run --dart-define=REVENUECAT_API_KEY=your_key_here
-```
-
-### Key works locally but not in CI/CD
-
-**Cause**: Secret not configured or not accessible
-
-**Solution**:
-1. Verify secret is added to CI/CD platform
-2. Check secret name matches exactly
-3. Ensure job has permission to access secrets
-4. Check if running on forked repository (secrets may not be available)
-
-### Different behavior in release vs debug
-
-**Cause**: Different API keys or missing configuration in release build
-
-**Solution**:
-- Ensure `--dart-define` is included in release build command
-- Verify production API key is correct
-- Check RevenueCat Dashboard for production vs sandbox configuration

-# RevenueCat Integration Guide
-
-This document explains how to configure and use RevenueCat SDK in BikeControl.
-
-## Overview
-
-BikeControl now supports RevenueCat for subscription management on iOS, macOS, and Android platforms. Windows continues to use the Windows IAP service.
-
-## Configuration
-
-### 1. Environment Variables
-
-Set your RevenueCat API key as an environment variable:
-
-```bash
-export REVENUECAT_API_KEY="your_api_key_here"
-```
-
-Or pass it during build:
-
-```bash
-flutter build ios --dart-define=REVENUECAT_API_KEY=your_api_key_here
-```
-
-### 2. RevenueCat Dashboard Setup
-
-1. Go to [RevenueCat Dashboard](https://app.revenuecat.com/)
-2. Create a new project or select existing one
-3. Configure your app:

-
-## Usage
-
-### For Users
-
-1. **First Launch**: Trial period starts automatically (5 days)
-2. **During Trial**: Full access to all features
-3. **After Trial**: Limited to daily command quota
-4. **Purchase**: Click "Unlock Full Version" to see paywall
-5. **Manage Subscription**: Click "Manage" button (visible after purchase)
-
-### For Developers
-
-#### Initialize RevenueCat
-
-RevenueCat is initialized automatically in `Settings.init()`:
-
-```dart
-await IAPManager.instance.initialize();
-```
-
-#### Check Entitlement
-
-```dart
-if (IAPManager.instance.isPurchased.value) {
-  // User has full version
-}
-```
-
-#### Present Paywall
-
-```dart
-await IAPManager.instance.presentPaywall();
-```
-
-#### Present Customer Center
-
-```dart
-await IAPManager.instance.presentCustomerCenter();
-```
-
-#### Restore Purchases
-
-```dart
-await IAPManager.instance.restorePurchases();
-```
-
-## Testing
-
-### Test Mode
-
-RevenueCat automatically detects sandbox environments:
-
-- **iOS**: Use TestFlight or Xcode sandbox accounts
-- **Android**: Use test tracks in Google Play Console
-- **macOS**: Use Xcode sandbox accounts
-
-### Debug Logs
-
-Debug logs are automatically enabled in debug mode. Check console for:
-
-```
-RevenueCat initialized successfully
-Full Version entitlement: true/false
-```
-
-## Troubleshooting
-
-### API Key Not Found
-
-If you see "RevenueCat API key not configured":
-
-1. Ensure `REVENUECAT_API_KEY` environment variable is set
-2. Or pass via `--dart-define` during build
-3. Check that the key is valid in RevenueCat Dashboard
-
-### Entitlement Not Working
-
-1. Verify product ID matches in:
-   - App Store Connect / Google Play Console
-   - RevenueCat Dashboard
-2. Check that product is linked to "Full Version" entitlement
-3. Verify offering is set as current in RevenueCat
-
-### Paywall Not Showing
-
-1. Ensure offerings are properly configured
-2. Check that at least one product is available
-3. Review RevenueCat Dashboard for configuration errors
-
-## Best Practices
-
-1. **Error Handling**: All RevenueCat calls include proper error handling
-2. **Fallback**: Legacy IAP service is used if RevenueCat key is not available
-3. **Customer Info Listener**: Real-time updates ensure immediate access after purchase
-4. **Platform Separation**: Windows maintains its own IAP implementation
-5. **Security**: API key should never be committed to source code

-
-4. Create Offering:
-   - Go to **Offerings**
-   - Create or edit the default offering
-   - Add `lifetime` product
-   - Set as current offering
-
-### Step 4: Configure Your Build
-
-Add your RevenueCat API key to your build:
-
-#### Option A: Environment Variable (Development)
-```bash
-export REVENUECAT_API_KEY="your_api_key_here"
-flutter run
-```
-
-#### Option B: Build Command (Production)
-```bash
-flutter build ios --dart-define=REVENUECAT_API_KEY=your_api_key_here
-flutter build apk --dart-define=REVENUECAT_API_KEY=your_api_key_here
-flutter build macos --dart-define=REVENUECAT_API_KEY=your_api_key_here
-```
-
-#### Option C: CI/CD (Recommended)
-Add `REVENUECAT_API_KEY` as a secret in your CI/CD environment:
-
-**GitHub Actions:**
-```yaml
-- name: Build
-  env:
-    REVENUECAT_API_KEY: ${{ secrets.REVENUECAT_API_KEY }}
-  run: flutter build ios --dart-define=REVENUECAT_API_KEY=$REVENUECAT_API_KEY
-```
-
-### Step 5: Test Your Integration
-
-1. **Build and Run**: Build your app with the API key configured
-2. **Check Logs**: Look for "RevenueCat initialized successfully"
-3. **Test Purchase Flow**:
-   - Click "Unlock Full Version"
-   - Should see RevenueCat paywall
-   - Complete test purchase (use sandbox/test account)
-4. **Verify Entitlement**: After purchase, should see "Full Version" status
-5. **Test Customer Center**: Click "Manage" button when purchased
-
-### Step 6: Production Checklist
-
-- [ ] RevenueCat project created and configured
-- [ ] Products created in App Store Connect / Google Play Console
-- [ ] Products imported to RevenueCat
-- [ ] "Full Version" entitlement created and linked to `lifetime` product
-- [ ] Offering created with `lifetime` product
-- [ ] API key added to CI/CD secrets
-- [ ] Test purchase completed successfully
-- [ ] Sandbox testing completed
-- [ ] Production testing completed (TestFlight / Internal Testing)
-
-## Important Notes
-
-1. **Never commit your API key** to source control
-2. **Use sandbox accounts** for testing
-3. **Product IDs must match** across App Store/Google Play and RevenueCat
-4. **Entitlement name** must be exactly `Full Version`
-5. **Windows users** will continue to use Windows Store IAP
-
-## Fallback Behavior
-
-If RevenueCat API key is not configured:
-- App will automatically use legacy IAP service
-- All features will continue to work
-- iOS/macOS will use `in_app_purchase` package
-- Android will use `in_app_purchase` package
-- Windows will use `windows_iap` package
-
