Privacy policy

Sudoception is private by design. The app has no account system, no analytics, no advertising SDKs and no servers of ours.

What we collect: nothing. Your puzzles, solve history and settings live on your devices and sync through your own iCloud account. Leaderboards and achievements go through Apple's Game Center under Apple's own privacy policy. We cannot see your times, your streak, or you.

Export and deletion. Your history can be exported as JSON at any time from the app. Deleting the app removes nothing from your iCloud until you choose to remove it.
