GAMMON / PRIVACY

Your game stays yours.

Gammon: Play & Learn works without a Gammon account. You can play, learn, and use the on-device coach without sending your game to us.

Information saved on your device

The app saves matches and move history, your player name, One Roll attempts, Learn to play progress, and preferences such as haptics and point numbers. This keeps your games resumable and your progress available after you close the app. Computer play and analysis use an engine bundled with the app.

iCloud sync

iCloud sync is on by default when an iCloud account is available. With sync on, Gammon sends saved matches, practice attempts and progress, learning progress, your player name, and selected preferences through Apple's CloudKit private database and iCloud key-value storage so they can appear on your other devices. The app uses your existing Apple account; there is no separate Gammon sign-in.

We do not operate a game server or have access to the contents of your private CloudKit database. You can turn off iCloud sync in Gammon Settings at any time. The device keeps its local copy, and data already in iCloud remains there unless you remove it from your iCloud storage.

Analytics, ads, and tracking

The Gammon app has no advertising SDK, third-party analytics SDK, or cross-app tracking. It does not sell your data. If you choose to email support, we receive the email address and information you send so we can reply; please avoid sending private match details unless they are needed to explain an issue.

Retention and deletion

Local game data remains on your device until you delete it in the app where that option is available or remove the app. Turning off sync stops future iCloud synchronization but does not erase data already stored in iCloud. Removing the app removes its local data; your iCloud copy may remain available for another device or a later reinstall. You can manage stored app data through your Apple account's iCloud storage controls. If you need help finding those controls, contact us using the address below. We cannot directly read or erase records in your private iCloud database.
