Thank you for using BaZi ("the App"), developed by Parse Studio 9. We are deeply committed to your privacy. This Privacy Policy explains how we handle your information.

• Birth data (date, time, location) for BaZi and Zi Wei charts
• Saved destiny charts and analysis history
• Marriage compatibility records
• Name analysis results
• Auspicious date preferences
• Interpretation and reading history
• Theme, language, and app preferences
• Subscription / Pro entitlement status (returned by Google Play Billing, cached locally)
• Free-tier usage counters — stored locally, reset daily

• Personal identifying information (name, email, phone number, etc.)
• Device identifiers or advertising IDs
• Usage analytics, behavioral data, or telemetry
• Location data
• Birth data, destiny charts, or any user-generated content

The App contains no advertising SDKs and no behavioral tracking SDKs.

3. Permissions Explained

4. Third-Party Services

5. Data Security

All user data resides on your device, protected by Android's built-in security mechanisms (file-based encryption, app sandboxing). We do not operate any servers, so there is zero risk of server-side data breaches. If you uninstall the App, all local data is permanently deleted.
