Gambit · Chess openings made simple
Privacy Policy
Gambit: Chess Openings ("Gambit", "the app") is made by Muleila Technology Inc. This page says what data the app uses, and why. The short version: there is no account, no advertising, no analytics and no tracking. Your lesson progress stays on your phone.
What stays on your phone
Your lesson progress and your settings (theme, pieces, sound, voice, language) are stored only on your device. We cannot see them. Deleting the app deletes them. You can also clear your progress at any time in Settings → Clear progress.
Purchases
Three lessons are free. The others unlock with one in-app purchase. Payment is handled entirely by Apple (App Store) or Google (Google Play); we never see your payment details.
To know whether you have unlocked the lessons, and to let you restore the purchase on a new phone, the app uses RevenueCat, a purchase service. RevenueCat keeps your purchase history (what was bought and when) with an anonymous app user id created on your device. This id is not linked to your name, email or Apple or Google account by us, and it is not used for advertising or tracking.
Lesson narration
The narration for the free lessons is inside the app. For a paid lesson, the narration downloads the first time you open that lesson, from our file storage on Cloudflare, and is then kept on your phone. Like any web server, Cloudflare receives the technical details of each download (such as your IP address) to deliver the files. From version 1.2, a paid lesson's narration download also carries the anonymous app user id described above, so that our server can check with RevenueCat that the lesson is unlocked. We do not use these details to identify you.
Reporting a problem
"Report a problem" in Settings opens your own email app with a message to us. We only receive what you choose to send, and we use it only to answer you and fix the problem.
What we do not do
- No account or sign-in.
- No advertising and no advertising ids.
- No analytics, no tracking across apps or websites.
- No selling or sharing of personal data.
- No access to your contacts, photos, location, camera or microphone.
Children
Gambit is suitable for all ages and is not directed at children under 13. Because the app collects no personal data from anyone, it collects none from children.
Your rights
Depending on where you live (for example under the GDPR in the EU or the UK, or the CCPA in California), you may have the right to ask what data is held about you and to have it deleted. The only data tied to your use of the app is the anonymous purchase record at RevenueCat. Write to us and we will help, including deleting it (a deleted record means a purchase can no longer be restored).
Changes
If this policy changes, we will update this page and its date.
