The short version
Playing is anonymous. Your songs, scores, settings and pad maps live in your browser and are never sent to us.
An account is needed only for Pro. It stores the minimum needed to recognise you and to know whether a subscription is active.
Payments are handled by Polar, our merchant of record. We never see card numbers.
No analytics cookies, no advertising, no third-party scripts on this site.
What the account stores
Your email address and display name, as provided by the sign-in method you chose.
The identifiers of the sign-in providers linked to the account (Google, Discord, or email link).
Your subscription status: plan, period and whether it is active, as reported by Polar.
The browsers you are signed in on, so that the account page can list them and sign them out. Up to five are kept; the oldest is signed out when a sixth signs in.
Why
To sign you in, to turn Pro on in any browser you sign in on, and to answer support requests about your subscription.
Retention
Account data is kept while the account exists. Deleting the account removes it within 30 days. Invoices are kept by Polar for as long as tax law requires.
Export and delete
The account page has Export data, which downloads everything stored about you as a JSON file, and Delete account, which removes it. You can also write to [email protected].
Billing data
Polar Software Inc. is the merchant of record. Polar collects the payment details, billing address and tax information needed to process the purchase, issues the invoice and handles refunds. Polar's privacy policy applies to that data.
Cookies and storage
The marketing site sets no cookies. The app keeps your library index, scores and settings in the browser's own storage, plus a signed-in session cookie when you have an account. A dismissed language banner is remembered in local storage.
