Privacy Policy

Last updated: June 2026

This policy describes how tringMUSIC handles personal data. It is provided for transparency and is not legal advice. We review it with qualified counsel for the markets we operate in.

1. Who we are

tringMUSIC ("tringMUSIC", "we", "us") is a piano practice-intelligence service. A player records a performance, our engine measures it, and we return a report and practice guidance. This policy covers our website, web app, and the people whose data we process: account holders (teachers, parents, and schools), the students whose performances are analyzed, and site visitors.

Registered address: 139 F, EA, Metropolitan Co-op Housing Society, Canal South Road, Kolkata 700105, India.

2. The accounts model

The person who signs up is the account holder and must be an adult (18 or older): a parent or guardian, a teacher, or a school. Students are managed profiles created under an account holder. A student may be a child. Students do not sign up directly and never authenticate through a social network. The account holder is responsible for the student profiles they create, including any consent required for a child's data.

3. Information we collect

Account data (via single sign-on): you sign in with Google, Microsoft, Facebook, or Apple. We never see or store your password for those services. We receive your name, email, a unique provider identifier, and where available a profile picture. Email is the key that identifies your account.
Student profile data: a name or nickname and age, provided by the account holder. This is strictly private, never public, never indexed, never shared with any third party.
Performance data: the MIDI files you upload and the metrics our engine derives from them (timing, dynamics, key fit, hand sync, phrasing, tempo, scores, reports). MIDI captures musical events only. It contains no audio recording of you, your voice, or your surroundings.
Technical and abuse-prevention data: device and browser information, app version, log data, and approximate location from IP address. To limit free-trial abuse we cap free-trial sign-ups to a small number per network per 24 hours. We store the IP in a hashed (pseudonymized) form for a short period and then delete it. This control applies to free-trial sign-ups only; paid users are not subject to it.
Payment data (paid plans only): payment is processed by our payment provider. We do not store card numbers or bank details.

We do not use advertising trackers, and the site does not load third-party fonts or analytics.

4. How we use your data

To analyze uploaded performances and produce reports and practice guidance.
To create and manage your account and student profiles.
To process payments and manage subscriptions.
To keep the Service secure and prevent abuse.

5. Who we share data with

We share data only with the service providers we need to run the Service, and only to the extent necessary:

Cloud infrastructure: our database and file storage provider (Supabase). Subject to their own privacy terms.
Payment processor: for subscription payments. Subject to their own privacy terms.
Authentication provider: the single sign-on provider you choose confirms your identity. We receive only your name and email.
Form delivery: contact and waitlist form submissions (your name, email, and message) are delivered to our inbox by our email provider (Resend), used only to send us your message. Subject to their own privacy terms.

6. Retention and deletion

You can request deletion of your account from your account settings or by contacting us. On a verified request, the account is deactivated immediately and all personal data (profile, students, sessions, MIDI files, analyses, and reports) is deleted and purged from our systems and backups within 30 to 40 days. Hashed IP records used for abuse prevention are kept only briefly and then deleted.

7. Your rights

Subject to applicable law, you may request access to, correction of, or deletion of your personal data, and you may withdraw consent for processing. To exercise any right, contact us using the details below. If you are in the EEA or UK, the GDPR gives you additional rights, including the right to lodge a complaint with a supervisory authority.

8. Cookies

We use only the session cookies necessary to keep you logged in. We do not use advertising cookies or third-party tracking cookies.

9. Children

We deliberately avoid creating accounts directly for children. A child participates only as a student profile managed by an adult account holder, who confirms they have the right to provide that child's data.

10. Grievance officer and contact

In accordance with the Information Technology (Reasonable Security Practices and Procedures and Sensitive Personal Data or Information) Rules, 2011 and the Digital Personal Data Protection Act, 2023, we have designated a Grievance Officer. To raise a privacy request or grievance, email [email protected]. We respond within the timelines required by applicable law.
