Boom 21 Privacy Policy
Effective date: July 4, 2026
Who we are
Boom 21 is a mobile card puzzle game developed by Hakan Özmen, an independent developer, and published under TadaApp. You can reach us anytime through the contact form.
The short version
Boom 21 does not collect, store, or share any personal data. There are no analytics, no ads, no tracking, and no account system. Everything the game knows about you stays on your device.
What Boom 21 collects
Nothing. The game contains no third-party analytics or tracking SDKs, no advertising networks or advertising identifiers, and no sign-up or account system. It does not access your contacts, location, camera, microphone, or any other personal information, and it never transmits data off your device.
Data stored on your device
Your progress — scores, run history, and settings — is stored locally on your device only. It is never uploaded or synced anywhere. Deleting the app deletes this data with it; because we never receive it, we cannot recover it for you.
Ads and purchases
Version 1.0 of Boom 21 contains no advertising of any kind. If a future version ever introduces features that involve data collection — such as ads or optional cloud sync — this policy will be updated first, and the change will be disclosed in the app before the feature is active.
Children's privacy
Boom 21 is intended for a general audience. Because the game collects no personal information from anyone, it also collects none from children.
Your rights & data requests
Since Boom 21 collects no personal data, there is nothing for us to export, correct, or delete. If you have any question about your data, contact us through the contact form and we'll answer directly.
Changes to this policy
If this policy changes in any meaningful way, we'll update the effective date above and, where appropriate, surface the change in the game or on this site.
