Privacy policy
Last updated 25 September 2026.
Tsuna does not collect personal data. There are no accounts, no ads, no analytics and no tracking.
What is stored on your iPhone
Your progress, settings and the board you are playing are saved on your device only. Deleting the app deletes them.
Game Center
If you are signed in to Game Center, Tsuna reports your achievements and leaderboard scores to Apple. Apple handles that data under its own privacy policy. Tsuna does not receive your Game Center identity for any other purpose.
Sharing
Share creates a picture of a solved board and hands it to the iOS share sheet. Nothing is sent anywhere unless you choose to share it.
Children
Tsuna collects no data from anyone, including children.
