Qubun does not collect, store or transmit any personal data. No accounts, no analytics, no advertising, no third-party SDKs.
Qubun saves a little information locally, in standard iOS storage:
All of it is removed when you delete the app.
When you are signed into iCloud, Qubun mirrors your name, your last-used settings and your best scores into Apple's key-value store, so they follow you across devices and reinstalls. Your language choice stays on the device and is never synced.
That store is an Apple service governed by Apple's privacy policy. The data is visible only to you, across your own signed-in devices. The developer cannot see it.
If you are not signed into iCloud, the sync is skipped and the app works entirely from local storage.
Qubun submits scores to Apple's Game Center leaderboards, split by session length. Game Center is an Apple service governed by Apple's privacy policy.
Signing in is optional and deferred: it happens only when you open the global ranking, never on launch.
The bundled privacy manifest declares UserDefaults (CA92.1) for the local data above, and File Timestamp (C617.1), used indirectly when the game loads its assets.
The manifest declares no tracking and an empty list of collected data types.
