Privacy Policy

Last updated: June 2026

Jam Jam is built to respect you. The app works entirely on your device and does not require an account. This policy explains the limited data involved when you choose to use the optional online features.

Your songs stay on your device

Your songbook, chords, lyrics and melodies are stored locally on your phone. They are not sent to our servers — keep your own backups.

What we store (only with an account)

Email — used only to sign you back in and prevent fake accounts. We never email you marketing without your explicit opt-in.
Profile — your chosen username and, optionally, an avatar (moderated for safety). Others can see your username, avatar and any songs you make public — never your email.
Activity — a “last active” date, to support optional newsletter preferences, and a device identifier to enforce one active session.

No tracking, no ads SDK on this site

This website uses no third-party trackers, analytics scripts or advertising SDKs. The app shows no ads to signed-out users on this version.

Where data is stored

Account data is hosted on Supabase (EU region) with row-level security so you can only access your own data. Avatar moderation uses Google Vision SafeSearch on the uploaded image only.

Your rights (GDPR)

You can access, export and delete your data at any time from the app (Profile → Export my data / Delete my account). Deletion is permanent and removes your profile, avatar and account.

Retention

We keep account data while your account exists. When you delete your account, the associated server-side data is removed.

Children

The Service is not directed to children under 13 (or the minimum age in your country). Do not create an account if you are under that age.

Changes & contact

We may update this policy; changes appear here with a new date. Questions or requests: privacy@jam-jam.org.
