Deep Mahjong ("we", "our", or "this app") is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use this app.
We do not collect, store, or transmit any personal data. This app does not require a user account. The hand data you enter for analysis, and the images captured by the photo recognition feature, are processed only on your device and are never uploaded to our servers.
All app data (hand analysis results, favorites, history, etc.) is stored locally on your device. Images captured by photo recognition are processed in memory only during analysis and are not saved or uploaded. We cannot access any information on your device.
This app does not integrate any third-party analytics, advertising, or tracking services. Subscription payments are handled by Apple StoreKit, and we do not collect or store your payment card information.
Because we do not collect any personal data, this app is suitable for users of all ages.
We may update this Privacy Policy from time to time. Any changes will be reflected on this page and the revision date will be updated.
