|
|

|
|
- Mobile analytics calls are now no-ops
|

|
|
|
|
**3. Analytics Index** (`features/analytics/index.ts`)
|
|

|
|

|
|
|

|
|
- Kept for backward compatibility
|
|
|
|
**5. Config** (`config.ts`)
|

|
|

|
|
|

**6. Layout** (`app/_layout.tsx`)

|
|
|
|
## Current State
|
|
|
|
### Mobile (iOS/Android)
|
|
- ✅ **No analytics tracking**
|
|
- ✅ All `useAnalytics()` calls are no-ops
|
|
- ✅ All feature flag checks return false
|
|
- ✅ No data sent to analytics services
|
|
- ✅ RevenueCat still works (B2B disable logic intact)
|
|
|
|
### Web
|
|
- ✅ **Umami analytics only**
|
|
- ✅ All analytics tracking functional
|
|
- ✅ No changes to web analytics behavior
|
|
|
|
## Backward Compatibility
|
|
|
|
All analytics hooks remain functional:
|
|
```typescript
|
|
// These still work but do nothing on mobile
|
|
const { track, identify, screen, reset } = useAnalytics();
|
|
track('event'); // No-op on mobile, works on web
|
|
identify('userId'); // No-op on mobile, works on web
|
|
|
|
// Feature flags always return false/empty
|
|
const isEnabled = useFeatureFlag('my-flag'); // Always false
|
|
const flags = useFeatureFlags(); // Always {}
|
|
```
|
|
|
|
## Next Steps
|
|
|
|
### If you want to re-enable analytics:
|
|
|
|
1. **Choose a new analytics provider** (e.g., Amplitude, Mixpanel, etc.)
|
|
2. **Install the package:**
|
|
```bash
|
|
npm install [new-analytics-package]
|
|
```
|
|
3. **Create new service file:**
|
|
- `features/analytics/services/analyticsService.ts`
|
|
4. **Update `multiPlatformAnalytics.ts`** to use new service
|
|
5. **Add initialization** to AuthContext (optional, if needed)
|
|
|
|
### If you want to keep analytics disabled:
|
|
|
|
- ✅ No action needed - current state is stable
|
|
- ✅ App continues to function normally
|
|
- ✅ All code is backward compatible
|
|
|
|
## Cleanup
|
|
|
|
To clean up your environment:
|
|
|
|
1. **Remove node_modules and reinstall:**
|
|
```bash
|
|
rm -rf node_modules package-lock.json
|
|
npm install
|
|
```
|
|
|
|
2. **Remove PostHog from environment files** (optional):
|
|
- `.env.dev`
|
|
- `.env.prod`
|
|
- `.env.example`
|
|
|
|
Remove these lines:
|
|
```bash
|
|
EXPO_PUBLIC_POSTHOG_KEY=...
|
|
EXPO_PUBLIC_POSTHOG_HOST=...
|
|
```
|
|
|
|
## Testing
|
|
|
|
Verify PostHog is completely removed:
|
|
|
|
```bash
|
|
# Search for any remaining PostHog references
|
|
git grep -i posthog
|
|
|
|
# Should only show this file and maybe some comments/docs
|
|
```
|
|
|
|
## Migration Notes
|
|
|
|
- **No breaking changes** - all analytics hooks still exist
|
|
- **No data loss** - RevenueCat and other services unaffected
|
|
- **No user impact** - app functionality unchanged
|
|
- **Web analytics** - continues to work with Umami
