Privacy policy
Last updated: November 13, 2026. This page explains what Muvamu Games stores and what it does not.
Data kept in your browser
Your best scores, recent games, favorite games, and chosen language are saved in your browser's local storage on your device. Guest records are not sent to us. Signing in uses a separate account cache on this device. Guest records are imported only when you choose to import them.
You can delete them at any time by clearing this site's data in your browser settings.
Accounts and personal information
You may sign in with Google or an email address and password using Firebase Authentication. Firebase manages your account identity and email; Google may supply a profile name. In Cloudflare D1 we store your Firebase uid, a nickname, a friend code, your favorite games, the friends you added, and your best result for each game in each hour of the last two days, in the current week and month, and of all time. Individual plays are not stored. Your nickname and best results are public: they appear on rankings and on record links you share. Your email address is never shown. Game answers stay in your browser. You can delete your account at any time under Your account: the account and everything stored for it on the server are removed, and Google sign-in is disconnected.
Hosting
The site is delivered through Cloudflare. As with any website, Cloudflare processes technical request data such as your IP address and browser type in order to deliver pages and protect the service.
Cookies and advertising
We show ads through Google AdSense, which keeps the games free. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and other sites on the Internet.
You can turn off personalized advertising in Google's My Ad Center, opt out of some third-party vendors' cookies at aboutads.info or, in Europe, youronlinechoices.eu, and block or delete cookies in your browser settings. Ads will still appear but may be less relevant.
If you are in the European Economic Area, the United Kingdom, or Switzerland, Google's EU user consent policy applies, and personalized ads are shown only with your consent.
Children
This site is not directed at children under 13, and we do not knowingly collect personal information from them.

This policy may change as the site changes. The date at the top of this page shows when it was last updated.
