Chess Defense is built to respect your privacy. We collect as little as possible, we do not sell anything to anyone, and there are no advertising trackers or third-party cookies.
Your game progress (levels, best scores, settings, mute preference) is stored locally on your device. It is not sent to us. The app does not require an account to play.
During the TestFlight beta, the app sends anonymous diagnostics so we can find and fix problems like performance drops. Each report contains a random device identifier (not linked to you or your Apple ID), your device model and iOS version, the app version, and gameplay/performance numbers such as frame rate, whether sound was on, which mode you played, and how far you got. It contains no personal information and is never sold or used for advertising. Apple also provides us with standard crash reports and performance metrics from TestFlight, as it does for any beta.
We use privacy-first, anonymous analytics to count page views and understand which pages are useful. It uses no cookies, collects no personal data, and does not track you across other sites. We cannot identify you from it.
If you email us to request TestFlight beta access, we receive your email address and whatever you write. We use it only to reply and to add you to the beta. We do not add you to any mailing list.
When the daily leaderboard is live, submitting a score stores a randomly generated device ID, the display name you choose, and your score for that day. This is not linked to your email or any personal information, and the display name is whatever you decide to enter.
The app is suitable for general audiences and does not knowingly collect personal information from children.
If this policy changes, the updated date above will change with it.
