Privacy Policy

Doku Duel does not use advertising, third-party analytics, or cross-app tracking, and the developer does not sell your data.

Data on your device

Doku Duel stores puzzle progress, completion history, and preferences on your device so the game can resume and remember your choices.

iCloud and Doku Dailies

When iCloud Daily sync is available, Doku Duel stores Daily puzzle progress and completion history in your private iCloud database. Synced records do not include your name, email address, contacts, or raw iCloud account identifier. In-progress Daily sessions are limited to a rolling 14-day UTC window; completion history may remain to calculate streaks.

Game Center

If you use Game Center, Doku Duel sends scores and achievement progress to Apple. The app uses an Apple-provided player identifier only to bind submissions to the current player and prevent duplicates; it does not place that identifier in Daily iCloud records.

Tracking, advertising, and sharing

The developer does not share personal data with advertisers or data brokers. Apple processes iCloud and Game Center data under Apple’s privacy terms.

Retention and control

Local game data remains until it is reset by the app or removed with the app. You can manage iCloud and Game Center data through your Apple Account settings.

For privacy questions, use the Doku Duel support contact listed on its App Store product page.
