Privacy Policy — Preferans
Effective date: May 20, 2026 · Developer: Boris Rayskiy · Contact: brayskiy@gmail.com
Information we collect
We do not collect any personal information. The app does not register accounts, ask for sign-in, or identify you in any way.
Data stored on your device
The app stores the following on your device only, using Android’s standard local storage (SharedPreferences and a single private file named pref_score):
- Your in-game preferences (table surface, card deck style, sound, vibrate, bidding conventions, etc.)
- Your local high-score table for completed games
This information never leaves your device. It is not transmitted to us, to any server, or to any third party. Uninstalling the app permanently removes it.
Network access
The app makes no network requests. It does not contain analytics, crash-reporting, advertising, or tracking SDKs of any kind. The Android manifest declares no internet permission.
Permissions
The app requests one Android permission:
VIBRATE— used solely to provide haptic feedback when it becomes your turn (if you have enabled the “Vibrate” option in Settings). This permission has no privacy implications.
Children’s privacy
The app is suitable for general audiences and does not knowingly collect any data from anyone, including children under 13. Because no data is collected at all, the app is compliant with COPPA, GDPR, and similar regulations by design.
Third-party services
The app uses no third-party services, SDKs, analytics, advertising, or content-delivery networks. The only third-party code in the app consists of standard Android system libraries (androidx.*, the Material Components library, Kotlin coroutines), none of which transmit data from this app.
Changes to this policy
If this policy is ever updated, the new version will be published at the same URL and the effective date above will change. Material changes will also be noted in the app’s release notes.
