Game progress. Your level, score history and identified languages are stored in your browser's local storage on this device. You can clear them at any time by clearing site data.
Leaderboard. When a level ends, your display name, total session score, level and best streak are sent to our backend so they can appear on the public leaderboard. Playing as a guest submits the name "Guest".
Accounts. Accounts are optional — the whole game works without one. If you create an account we store your email address (for sign-in and password resets) and the display name you choose, which is shown publicly on the leaderboard. You can change your display name or delete your account at any time from your account page. Deleting your account removes your profile and detaches your past leaderboard entries from it.
Analytics. We record anonymous gameplay events (such as run started, answer submitted, clip failed to load) to balance difficulty and fix audio problems, and we use Google Analytics 4 to count visits and page views. These events carry no names, emails or other personal identifiers.
Cookies. Google Analytics sets its own cookies. Every storage key the game uses is listed in our cookie policy, and clearing site data removes all of them.
Advertising. The site shows ads served by Google AdSense, which may set its own cookies or device identifiers to measure and personalise advertising. You can manage this through Google's Ad Center and your browser settings. See our cookie policy for details.
