Looking at the changes:
1. **New files**:
- `app/(app)/(tabs)/profile/account-deletion.tsx` - account deletion screen
- `app/(app)/(tabs)/profile/privacy-settings.tsx` - privacy settings screen
- `src/screens/profile/AccountDeletionScreen.tsx` - account deletion implementation
- `src/screens/profile/PrivacySettingsScreen.tsx` - privacy settings implementation
2. **Modified files**:
- Database changes: `LocalDataSource.ts`, `DatabaseManager.ts`, `DatabaseConfig.ts`, `MigrationManager.ts` - refactoring database layer (removing LockManager, simplified initialization, added retry logic)
- Auth store: `authStore.ts` - changed `initDatabase` to `switchDatabase`
- Auth service: `authService.ts` - added privacy settings and account deletion methods
- DTOs: `dto.ts` - added PrivacySettingsDTO, DeletionStatusDTO, VoteOptionDTO, VoteResultDTO types
- Navigation: `hrefs.ts` - added new href functions for privacy settings and account deletion
- Profile screens: `SettingsScreen.tsx`, `index.ts`, `_layout.tsx` - added new menu items and routes
- Various message screens - added keyboard handling props
- `app/_layout.tsx` - added CSS for mobile touch handling
- `CreatePostScreen.tsx` - fixed vote_options format
- `PostDetailScreen.tsx` - added type annotations for vote handling
- `MediaCacheManager.ts` - updated to use new expo-file-system API
- `VerificationSettingsScreen.tsx` - fixed type safety
- `AccountSecurityScreen.tsx` - styling refactoring
This is a multi-faceted change involving:
Database refactoring, new privacy/account deletion features, bug fixes, and UI improvements. The database changes appear to be refactoring without new functionality. The most significant changes are the privacy settings and account deletion features, plus bug fixes like the vote options format and mobile touch handling.
