Microphone

Timing feedback is on by default, but microphone access is optional. When you press Play, your browser asks permission before access starts; you can turn timing feedback off before playing or deny permission and still play. Audio is processed in your browser to estimate when you start speaking and calculate a timing score. We do not record, save or upload microphone audio.

Your own audio files

Audio files you select are decoded and played locally in your browser. They are not uploaded to our servers. A shared challenge link never includes a local audio file.

Linked music

When you paste a YouTube or SoundCloud link, its preview and player connect directly to that provider. Their own privacy terms and cookies may apply. We do not upload the link or save it on our server, and linked beats are not included in challenge links.

Practice data

Your selected settings and practice totals may be stored in your browser's local storage. You can remove them by clearing this site's data in your browser. Challenge links contain only game settings and a random seed, not your voice or results.

Hosting

Like other websites, the hosting provider may process basic connection data to deliver the site. Its details will be added before public launch. No third-party analytics or advertising scripts are included in this first version.
