Data stored on your device
Game data (high score, best WPM, settings, local leaderboard, cookie-consent
choice) is kept in your browser's localStorage. It never reaches a
server; clearing site data removes it entirely.
Voice input
The optional voice mode uses your browser's built-in speech recognition (the Web Speech API). While it is active, audio from your microphone is processed by your browser vendor's speech service (e.g. Google for Chrome, Apple for Safari) to produce text; see your browser's privacy policy for details. This site never records, stores or transmits your audio or transcripts — recognized text is matched against the on-screen words in your browser and discarded. Voice mode only runs after you grant microphone permission and can be left off entirely.
Analytics
If you accept the cookie banner, Google Analytics (GA4) is loaded to measure aggregate usage with IP anonymisation enabled. If you decline, it is never loaded.
Advertising
This site can display Google AdSense advertising. Declining consent requests non-personalised ads only. Google's use of advertising cookies is described in Google's own policies.
