What we collect
Account data (username, email, optional country), practice and pitch session metrics (counts, accuracy, duration—not audio), subscription status via Stripe, and optional approximate location if you consent at signup.
Microphone audio
Pitch detection runs in your browser. Microphone audio is not uploaded or stored on our servers. Only numeric accuracy stats may be saved when you are logged in.
How we use data
To provide training features, sync progress across devices, process payments, improve the product with aggregate analytics, and secure accounts (login protection, audit events).
Payments
Payments are processed by Stripe. We store subscription status and Stripe customer/subscription IDs—not full card numbers.
Retention and your rights
You may request account deletion or a progress export from the app where available. Contact the operator of this deployment for privacy requests. Keep passwords private; we never ask for them by email.
