Camera and photos

• The camera is used only to scan a printed sudoku. The photo is processed on the phone and is never sent anywhere.
• The app opens a photo from your library only when you choose it yourself.
• The app saves to Photos only an image that you share and save yourself.

Digit recognition

• Digits are recognized on the device (Apple Vision on iPhone, Google ML Kit on Android) without an internet connection.

Data storage

• Saved sudoku, games in progress, statistics and settings are stored only on this device.
• You can delete everything in Settings → Delete all data, or by uninstalling the app.

Sharing

• Sharing happens only at your request through the phone’s system share sheet; the app itself sends nothing.

Children
