My Lesson Studio holds records about music lessons, and some of those lessons are taught to children. This says what is kept, who can see it, and how to have it removed.
Who holds the information
Each studio belongs to the teacher who created it. The teacher decides who is in it and what is written down; My Lesson Studio provides the software and stores the records on the teacher's behalf.
In data-protection terms the teacher is the controller of their studio's records, and My Lesson Studio is a processor acting on their instructions.
What is stored
Accounts
- Email address and password. Passwords are stored only as a hash — nobody, including us, can read them.
- Name, and phone number if given.
- Whether the account is a teacher, a student or a guardian.
Studio records, written by the teacher
- Student name, instrument, email address, lesson day and time, lesson length, where the lesson happens.
- Guardian name, relationship, email address and phone number.
- Lessons, cancellations, studio closures.
- Homework, the piece being worked on, and lesson notes.
- Practice logged by the student.
- Tuition rate, invoices, and payments recorded against them.
- Messages and announcements between the teacher and the family.
Files
- Short audio clips recorded during a lesson, or by a student practicing. Sound only — the app has no camera.
- Photographs of sheet music.
- Photographs of payment receipts.
Technical
- A notification token for the device, if notifications are turned on. It is used to deliver reminders and nothing else.
- Reminder and notification preferences.
There is no analytics, no advertising, and no tracking of any kind. Nothing is sold, and nothing is used to train machine-learning models.
Who can see it
Access is enforced by the database itself, not only by the app. Every request is checked against the account making it.
- A teacher sees only their own studio.
- A student sees only their own record — their lessons, homework, practice and invoices.
- A guardian sees only the students they are attached to.
- No studio can see another studio. Nobody browses the app to find a teacher; joining requires a code from that teacher, and the teacher approves the request.
Students under 18
Plenty of private teaching is adults, and an adult student's record works like anyone else's. Where a student is under 18, a guardian can be attached to their record, and the guardian sees what that student sees.
A guardian can ask, at any time, to see everything held about the student, to have it corrected, or to have it deleted. Ask the teacher first — it is their studio and they can do all three from inside the app. If that does not resolve it, write to the address at the bottom of this page.
Recordings deserve saying twice: the app can record a student playing. Sound only — it does not use the camera and holds no pictures of anyone. Clips are stored privately, are readable only inside that student's own studio, and are deleted when the record they belong to is deleted.
Where it is kept
Records and files are stored with Supabase Inc., which provides the database, file storage and sign-in. Email is delivered by Resend. Push notifications are delivered through Expo and the device maker's own service — Apple or Google.
These companies process the information on our instructions to run the service, and for nothing else.
How long it is kept
Recordings are deleted automatically. Each studio sets how long it keeps them — thirty days unless the teacher changes it — and past that the app removes the clip and the file behind it. A recording of a child is the one thing here worth not keeping.
A studio's other records are kept while the studio exists. Deleting a student deletes their lessons, homework, practice, invoices and files with them.
Deleting an account is available inside the app, under Settings. It removes the account and everything it owns, and it cannot be undone.
Your rights
Depending on where you live, you may have the right to see what is held about you, to correct it, to have it deleted, to receive a copy, or to object to how it is used. Ask the teacher whose studio holds the record — they can act on all of these directly. If you cannot reach them, or are not satisfied, write to the address below.
Changes
If this notice changes in a way that matters, the date at the top changes and the app says so.
