Cookies & Local Storage
Flipudoku uses browser storage so the game can remember your progress and settings. The website does not use advertising or analytics cookies.
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. This information stays in your browser and is needed for the features you request.
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 Flipudoku's Settings to reset game data, or clear this site's storage in your browser. Clearing it removes progress and preferences and cannot normally be undone. Because the website does not use optional advertising or analytics cookies, it does not display a cookie consent banner.
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.
