2. Summary

Chess Tactics does not collect, store or transmit any personal data. The app requires no user account, works entirely offline and contains no advertising, analytics or tracking.

3. Data processed by the app

Everything created while training — solved puzzles, rating, accuracy, solving times — is stored locally on your device only. This data never leaves your device. We have no access to it and never receive it. The app requests no permissions for location, contacts, camera, microphone or photos.

4. No network connection during use

Training works completely without an internet connection. The puzzle collection and the chess engine are part of the app and run locally on your device.

5. In-app purchase

The full version can be unlocked with a one-time in-app purchase. Payment is handled entirely by Apple (StoreKit). We receive no payment details, no address data and no Apple Account information — only aggregated, non-personal sales reports from Apple.

Apple's privacy policy applies to the payment process: https://www.apple.com/legal/privacy/

The purchase state is stored locally on your device so that the full version remains available without an internet connection.

6. No advertising, no analytics

The app contains no advertising, no ad networks, no analytics tools and no third-party libraries that transmit data.

7. Deleting your data

Since all data is stored locally, deleting the app from your device removes everything. No separate deletion request is necessary, as we hold no data.

8. Your rights

Under the GDPR you have the rights of access, rectification, erasure, restriction of processing, data portability and objection. As we process no personal data, these rights have no subject matter with regard to us. You may nevertheless contact us at the address above at any time. You also have the right to lodge a complaint with a data protection supervisory authority.

9. Changes to this policy

If the scope of the app changes, this policy will be updated accordingly. The version published on this page is the applicable one.
