ALTOSPIN is a private music vault. Your masters, releases, and account data are not public. Only you (and platform administrators for support and abuse prevention) can access your content while you have an account.
We store account information through third-party authentication and database services and audio files through cloud storage providers. Email for sign-in and notifications is sent through a transactional email provider. These providers process data on our behalf to run the service.
We do not sell your personal data. We use your email to authenticate you and send account-related messages (confirmations, password resets, security notices). If you opt in as a member, we may also email you about new comments or releases in your collection.
You can delete your account from Account settings (Danger Zone). Artist accounts lose tracks, releases, and associated files; member accounts lose their profile, collection, and preferences. Brief backup retention by infrastructure providers may apply.
