Privacy Policy
Chess GM Champion

Effective date: 9 July 2026 · Published by MaxLeaf

In short: we collect no personal data. Chess GM Champion runs entirely on your device. There are no accounts, no ads, no analytics, and the app makes no network requests. Nothing you do in the app is ever sent to us or to anyone else.

Who we are

Chess GM Champion is a single-player chess app published by MaxLeaf. If you have any questions about this policy, contact us at support@maxleaf.in.

Information we collect

None. We do not collect, transmit, sell, or share any personal information. The app has no sign-up or login, requests no permissions to identify you, and includes no advertising or analytics software.

Information stored on your device

To make the app useful across sessions, the following is saved only on your device using your browser/app local storage (localStorage):

This data never leaves your device. We have no servers and cannot access it. It is not backed up to us and is not synchronized to any cloud service by the app.

No network requests

Everything the app needs is bundled inside it. The chess engine (Stockfish) runs locally on your device, and the fonts and chess-piece graphics are packaged with the app. The app does not connect to the internet to function, so it works fully offline.

No cookies or tracking

The app does not use cookies, advertising identifiers, tracking pixels, or any third-party software development kits (SDKs).

Children's privacy

Chess GM Champion is suitable for all ages. Because the app collects no personal data from anyone, it collects no data from children. It contains no ads, no purchases, and no communication features.

How to delete your data

Because all data is stored locally on your device, you are in full control of it. To erase everything, clear the app's storage/data in your device settings, or simply uninstall the app. There is no account to close and nothing for us to delete on our side.

Changes to this policy

If this policy changes, we will update the effective date at the top of this page and publish the revised version at the same location. Continued use of the app after an update means you accept the revised policy.
