Privacy

Quatre Duo uses Apple’s public simultaneous-display feature to show one shared game on iPhone Duo’s inner and outer displays. On hardware, this feature requires an active rear-camera session. The app requests camera permission for this purpose.

Quatre Duo does not show a camera preview, record, save, analyze or transmit camera frames, photos or video. It does not request microphone access. The camera session stops while the main scene is inactive.

You can revoke camera access in Settings. Without that permission, the two-display game cannot run. Your saved game remains on your device.

The board, scores and sound preference are stored locally in the app. Quatre Duo does not send them to Arctic Studios and has no cloud game service. New match clears the board and scores. Deleting the app removes its local data, subject to your device’s normal backup and restore behavior.

Quatre Duo has no account, advertising, analytics SDK, tracking, in-app purchase or game network service. Arctic Studios does not collect personal data through the app.

If you email the studio, the information you choose to send is used to respond to your request. Avoid sending passwords or private camera images. Website hosting is separate from the game; see the studio website privacy policy for website visits.
