Privacy
Chord Roulette works without an account, and then everything you make stays in this browser.
Your email
If you sign in, your email address is your account. It is used only to sign you in. It is never sold.
What your account keeps
Your saved progressions, beats, rhythms, kits and settings are stored in your account, so they follow you when you sign in on another browser. A rhythm keeps the notes taken from your MIDI file, not the file itself. For sounds you add, only the file name, size, length, type and a fingerprint of the file are stored, so the app can match it. What you made before signing in moves to your account only if you choose to move it.
What stays in this browser
The audio files themselves never leave this browser. They are kept in its storage. It also remembers folders you pick, so you can open them again. Signing in keeps a session token in this browser's storage too.
Who handles your data
- Supabase stores your account and library, in the United States (California).
- Resend delivers the sign-in emails.
- Cloudflare hosts the site and counts visits with Cloudflare Web Analytics.
Supabase and Cloudflare see your IP address when this browser connects to them, as any website's servers do.
Analytics and cookies
Cloudflare Web Analytics counts page visits without cookies and does not track you across sites. There is no advertising. Chord Roulette sets no cookies.
Deleting your account
Open Settings, then Account, then Delete account. Your account is removed right away, and with it your progressions, beats, rhythms, kits and settings. You can also remove the audio stored in this browser at the same time. Your original files on your computer are not touched. Signing out alone leaves your audio in place.
Backups and logs
The database is backed up daily, and each backup is kept for 7 days. Deleted data may remain in backups for up to 7 days. Service logs, such as sign-in records, may be kept for a limited time.
