Privacy Policy

• Account: your email and authentication identity (via our sign-in provider), and a display name.

• Practice data: your progress, scores, streaks, achievements, settings, saved projects and any content you create in the DAW/tools.

• Audio: live audio from your microphone or instrument (amp/tuner/training) is processed in your browser and is not uploaded or stored unless you explicitly save a project.

• Billing: handled by Stripe — we store a customer reference and plan status, never your card details.

• First-party usage counts: anonymous aggregates to understand the product. No third-party analytics SDK.

No advertising. No selling or renting of personal data. No third-party behavioural trackers. We don't listen to or retain your live audio.

We rely on a small set of infrastructure providers:

• Vercel — application hosting and delivery.

• Neon — managed PostgreSQL database (account + practice data).

• Stripe — payments and subscription management.

• Resend — transactional and support email.

• Mux — video lesson hosting and playback (where used).

Data may be processed in the United States by these providers. We keep this list current.

Request a full export or permanent deletion of your account and practice data at any time. Email privacy@instrument.ninja.

For EDU/classroom use, the teacher or institution is responsible for any consent their policies require. We show no ads to any user, including students. See Security.
