五大 Godai (“the app”) is a two-player card game. This policy explains what happens to your data when you play it.
Game Play: Local gameplay does not collect, store, or transmit any personal data. Game state lives only in memory on your device and is never sent to our servers.
Optional Account Features: You may optionally create an account to access leaderboards and track your match history. If you choose to create an account, we collect:
Your email is used only for authentication and sending account-related messages (verification, password reset). We do not use it for marketing or share it with third parties.
All account data is stored securely and encrypted. You may delete your account at any time by contacting us.
We use MongoDB Atlas for database hosting and Postmark for sending transactional emails (verification and password reset). These services process data only as necessary to provide their specific functions.
The app does not use analytics services or display advertising of any kind.
The app does not request access to your camera, contacts, location, photos, or any other device data beyond what is required for basic app functionality.
Our account features are not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe we have collected such information, please contact us to have it removed.
If this policy changes, this page will be updated with a new “Last updated” date. Continued use of the app after changes constitutes acceptance of the updated policy.
