Let me analyze the changes:
1. PrivacyPolicyScreen.tsx:
- Updated LAST_UPDATED date from '2026年4月4日' to '2026年4月28日'
- Added detailed third-party SDK disclosure section:
- Added JPush (极光推送) with provider details, purpose, collected data, and privacy policy link
- Added Expo推送服务 with provider details, purpose, and collected data
2. TermsOfServiceScreen.tsx:
- Updated LAST_UPDATED date from '2026年4月4日' to '2026年4月28日'
- Added section 6.4 about third-party SDKs (JPush) and reference to privacy policy
These changes are:
- Documentation/legal text updates
- Related to privacy and terms screens
- Adding third-party SDK disclosure (JPush)
The primary type should be: docs (documentation changes)
Scope could be: profile or privacy/terms related
Description should focus on the third-party SDK disclosure update
This is different from the previous commit which was about notification integration. This commit is about updating legal/policy documents to disclose third-party SDKs.
Let me craft a conventional commit message:
type: docs
scope: profile or privacy
description: update privacy policy and terms to disclose third-party SDKs
Body could explain:
- Added JPush SDK disclosure with provider info, data collected, privacy policy link
- Added Expo push service disclosure
- Updated terms of service to reference third-party SDKs
- Updated last update dates
Breaking changes: None
Footer: Could reference related issue if any, but none provided.
Let me write the commit message:
```
docs(privacy): update privacy policy and terms to disclose third-party SDKs
- Add JPush SDK disclosure with provider details, data collection purposes, and privacy policy link
- Add Expo push service disclosure with provider and collected data information
- Update terms of service to reference third-party SDK usage
- Update document dates to April 28, 2026
```
I need to verify this is sufficiently distinct from the previous commit. The last one was "feat(notification): integrate expo-notifications..." so using "docs(privacy)" with this specific focus on third-party SDK disclosure makes sense and clearly differs from the prior notification feature work.
</think>

- `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`

The most significant changes are the privacy settings and account deletion features, plus bug fixes like the vote options format and mobile touch handling.
</think>
