Cookies & Local Storage

Flipudoku uses browser storage so the game can remember your progress and settings. Optional anonymous analytics are activated only after your permission.

What is stored?

The website may store current and completed games, achievements, streaks, challenge progress, theme, colour palette, language, sound, animation and reminder preferences, onboarding state, and your acknowledgement of legal information. If you allow analytics, it also stores your choice, a random installation identifier and a short event delivery queue.

Anonymous analytics

With your permission, limited usage events are sent to Flipudoku's first-party analytics endpoint. These events are described in the Privacy Policy. Flipudoku does not use advertising cookies on the website.

Hosting data

Our hosting/security provider may use strictly necessary technology and technical logs to deliver and protect the website. See the Privacy Policy.

Your controls

Use the Anonymous analytics switch in Settings to give or withdraw permission. Turning it off removes the local analytics identifier and pending events. You can also reset all game data or clear this site's storage in your browser.

Mobile app

The mobile app uses local app storage and may use Google AdMob. Advertising consent and privacy choices are handled separately in the app where required.
