Zarbdar Privacy Policy

Effective 3 October 2026 · Updated 3 October 2026

Zarbdar is a word game: a crossword you build as you play. This policy explains what happens to information when you use the Zarbdar app on Android or play it in a web browser.

The short version

Zarbdar has no ads, no analytics and no tracking, and never sells or shares your data. You can play without an account: your progress then stays on your device. On zarbdar.app you can choose to sign in with Google to keep your progress online; only then is anything stored on our servers, and you can delete it at any time.

What stays on your device

To keep your progress between games, Zarbdar saves the following on your own device:

• your level, scores, badge and best board;
• the words you played recently (so new boards feel fresh) and a record of finished boards;
• an estimate of your skill, used only to set the difficulty of the next crossings;
• your settings: light or dark mode, and music on or off.

Uninstalling the app (or clearing the browser's site data) deletes it. On Android, the system's own device backup may include it if you have turned backup on; that backup is handled by Google under your Google account settings, not by Zarbdar.

If you sign in with Google (zarbdar.app only)

Signing in is optional and only available on the website; the Android app has no sign-in. When you sign in with Google, Google tells us your Google account ID, your name and your email address. We store, on Cloudflare's servers:

• your Google account ID, name and email address, and when you signed up and last signed in;
• your progress, the same items listed above (level, points, best board, badge, skill estimate and recent words), so it follows you to other browsers and devices;
• a sign-in session for each browser you use, held in a cookie (only a scrambled copy of it is stored), which expires after 180 days.

We use this only to sign you in and keep your progress. We never use it for advertising, never send you marketing email, and never share or sell it. We do not receive your Google password or anything else from your Google account.

Deleting it: open the About page from the (i) button on the start screen and choose Delete my account. Your account, saved progress and sessions are deleted at once. You can also email us to have them deleted. Signing out removes the session from that browser.

Cookies

zarbdar.app sets one cookie, and only after you sign in: zb_session, which keeps you signed in. It is necessary for sign-in and is not used for tracking. Google's sign-in button may set its own cookies when you use it, under Google's privacy policy.

Service providers

• Cloudflare hosts zarbdar.app and stores the account data above.
• Google provides the sign-in (Google Identity Services).

Permissions

• Vibration: small taps of feedback when you type and when you score.
• Internet (Android app): part of the standard Android app shell. The app loads everything from inside itself and makes no network requests.

Children

Zarbdar is not directed at children under 13, and we do not knowingly store information about children under 13. If you believe a child has signed in, email us and we will delete the account.

Changes

If this policy changes, the new version will be posted on this page with a new effective date.
