Privacy policy

Last updated: November 10, 2026.

This policy explains what information Letter Keep (“we”, the game at letterkeep.app) collects and how it is used.

Playing without an account

If you play without signing in, your progress (the words you found, your castles, your name and coat of arms if you chose them, and your settings) is stored only in your browser’s local storage. It never leaves your device. Clearing your browser data deletes it.

Signing in with Google

If you choose to sign in with Google, we receive your Google account identifier, your email address and your name from Google. We store them together with your game progress (the words you found each day and your results) so you can play on other devices. We do not get your Google password and we don’t post anything to your Google account.

Analytics

We use Google Analytics to understand how the game is used (for example, how many people finish the tutorial or reach the 80% mark). It uses cookies or similar technologies and collects information such as pages visited, approximate location and device type. In the European Economic Area, the United Kingdom and Switzerland, analytics cookies are off by default. You can learn more at How Google uses information from sites that use its services.

Advertising

Letter Keep may show ads served by Google and its partners. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the internet. You can opt out of personalized advertising at Google Ads Settings, or opt out of some third-party vendors’ use of cookies at aboutads.info. Where required by law, we will ask for your consent before using cookies for advertising.

How long we keep data

Account data is kept while your account exists. You can ask us to delete your account and all its data at any time.

Children

Letter Keep is a general-audience game and is not directed at children under 13. We do not knowingly collect personal information from children under 13.
