Privacy policy
Gambit reviews your chess games. Here’s exactly what that involves, in plain language.
The short version
- No account: Gambit only needs your Chess.com username.
- No ads, no analytics SDKs and no tracking. We never sell your data.
- To review your games, Gambit sends them to its server and to Anthropic’s Claude, which writes the coaching.
- Your history and preferences sync to Gambit’s server so they follow you between devices.
Who we are
Gambit is made by Jack Cornet Paterson, an independent developer based in Spain, who is responsible for your data under this policy. You can reach us at support@get-gambit.app.
What Gambit uses, and why
Your Chess.com username and public games. Gambit uses the username you enter to fetch your public profile, avatar and recent games from Chess.com’s public API. It can only see what Chess.com already shows publicly.
Game reviews. When you analyze a game, its moves (PGN), the players’ names and ratings, and your language are sent through Gambit’s server (hosted on Supabase) to Anthropic’s Claude API, which writes the review and pattern insights. Anthropic processes this to return the result and doesn’t use it to train its models. See Anthropic’s privacy policy.
Sync. To keep your coaching consistent, Gambit stores the following on its server, linked to your Chess.com username: your reviewed games and their reviews, pattern insights, and app preferences (notation, board theme, language, sync and notification settings).
Notifications. If you turn on import alerts, Gambit stores your device’s push token, your Chess.com username, language and the time of your last notified game, and uses Apple Push Notification service to tell you when a new game is ready.
On your device. Saved reviews, imported games, cached coaching and settings are also kept on your iPhone or iPad.
You can turn notifications off at any time in the iPhone Settings app.
Purchases
Gambit Pro is sold through Apple, which handles payment. We never see your card details. Gambit uses RevenueCat to check which features you’ve unlocked and to restore purchases; RevenueCat receives an app user ID, your purchase history and basic device information. See RevenueCat’s privacy policy.
If you email us
If you write to support@get-gambit.app, we use your email address and what you send only to reply. We don’t add you to a mailing list.
This website
get-gambit.app has no cookies, analytics or trackers. It’s hosted on Cloudflare, which processes basic technical data such as IP addresses to deliver and protect the site.
How long we keep data
Data on your device stays until you delete it or remove Gambit. Logging out in Gambit clears your username and imported games from the device and unregisters notifications. Data synced to Gambit’s server is kept while it supports a feature; to have it deleted, email us with your Chess.com username. Purchase records are kept by Apple and RevenueCat under their own policies.
Your rights
Under the GDPR and similar laws, you can ask to access, correct or delete your personal data, object to its use, or receive a copy. Email support@get-gambit.app and we’ll reply within 30 days. You can also complain to your data protection authority. In Spain, that’s the Agencia Española de Protección de Datos (aepd.es).
Children
Gambit isn’t aimed at children under 13, and we don’t knowingly collect personal data from them.
Changes
If this policy changes, we’ll update this page and the date at the top. If a change affects how your data is handled, we’ll tell you in the app first.
