Fendoku privacy policy
Updated September 28, 2026. Developer: Nathan Fennel.
Progress, settings and themes
Fendoku stores puzzle progress, completion times, unlocks, hint counts, settings, custom themes and puzzle caches on your device. When available, the app synchronizes progress through your private iCloud database. That progress can include saved Game Center rivalry standings with player identifiers, display names, scores and ranks. Settings and custom themes are stored locally and are not synchronized by this progress feature. The developer does not receive your private iCloud progress through a developer-operated server.
Game Center
If you use Game Center, the app uses Apple's sign-in interface, submits scores and achievements, and requests friend leaderboard standings. Apple processes this information under its Game Center privacy notice. Scores, nicknames and other activity may be visible to other Game Center users according to Apple's controls. Manage Game Center sign-in, activity sharing and friend-list access in your device's settings.
Diagnostics, links and sharing
The app keeps up to 20 local MetricKit diagnostic files to help investigate performance and errors. No diagnostic uploader, developer-operated analytics service, advertising SDK or payment service is included in this version. Choosing the Wikipedia link opens that website in your browser, where its own privacy practices apply. Sharing an image or animation uses the system sharing destination you choose.
Retention and deletion
Progress and preferences remain until removed through the relevant device or storage controls. Deleting the app does not necessarily remove private iCloud progress, Game Center records, shared exports or device backups. Apple controls retention for its services. A failed save is shown in the app so you can retry; unreadable saved files are preserved rather than replaced with empty progress. Contact the developer if you need help locating app data. Information you send in a support request is used to respond.
