What we collect
We collect your account email and name (via your login provider), your membership and billing status, and the metadata of masters you choose to save — title, artist, loudness figures and target platforms.
Your audio
Mastering runs entirely in your browser. Your audio file is never uploaded unless you explicitly press "Save to Library", in which case the mastered WAV is stored in private storage that only your account can access.
Payments
Subscriptions are processed by Stripe. We never see or store your card details — we only store the Stripe customer and subscription identifiers needed to manage your plan.
Deleting your data
You can delete your account at any time from Settings. This permanently removes your account record and every saved master associated with it.
