Privacy policy

In short

TONIC is a learning app for audio production and music theory. Your teacher creates your account. We keep what is needed to run your account and your progress, we show no ads, we use no tracking or analytics tools, and we do not sell anything about you.

What we keep

• Your account: your name, your email address and your password. The password is stored only as a one-way scrambled value, so nobody can read it, not even us.
• Sign-in records: when you last signed in, and the kind of browser or phone of each device you are signed in on, so that you can be signed out of it.
• Your progress: the lessons, quizzes and challenges you have done, your scores, points, streak, daily goal, display name and character. It is saved to your account so it follows you to another device.
• Feedback you send: your message, the page you were on, and the kind of device.
• Questions to REV: when you ask REV something, your question and what you are studying are sent to our server and on to Google's Gemini and Gemma AI service, which writes the answer. Please do not type personal details to REV. We do not keep what you typed; we only keep a copy of general answers that do not depend on you, so the same question is answered faster.

What stays on your phone

Your display and sound settings, your reminder choice, and a saved copy of lessons you have opened (so they work without a connection). Reminders are scheduled by your phone itself. Nothing about them is sent to us.

Who can see it

• Your teacher (the one who made your account) can see your progress, your report and the feedback you send.
• Services that run TONIC for us: web hosting (Vercel), the database that stores accounts and progress (Neon), and Google's AI service for REV's answers. They handle data only to provide those services.
• Nobody else. We do not sell or rent your data, and we do not use it for advertising.

What the Android app asks for

Permission to show notifications (your practice reminders, which you can turn off in Settings) and access to the internet. It does not ask for your location, contacts, files or camera.

Keeping and deleting

Your data is kept while your account exists. If you want your account and everything in it deleted (progress, feedback and sign-in records), ask your teacher or write to us at the address below, and it will be removed.

Age

TONIC is for learners aged 13 and over. It is not meant for younger children, and we do not knowingly keep their data.

Keeping it safe

Everything travels over an encrypted connection. Passwords are never stored in a readable form, sign-in attempts are limited, and a sign-in session ends when you sign out.

Changes

If this policy changes, the date at the top changes with it.

Contact

The contact address is being added before the public release. Until then, ask your teacher.
