Privacy policy
Last updated: 13 October 2026
This policy covers the website classmgt.com and the mobile app Maestro Class Management (iPhone, iPad and Android). Maestro is a management system for schools — music schools, art studios and other schools with private and group lessons.
Who is responsible for your data
Each school that uses Maestro decides what data it keeps about its students, parents and instructors. The school is responsible for that data. Maestro (operated by Rabeh Mansour) stores and processes the data on the school's behalf, only to run the service.
Data in the app
Accounts are created by the school; there is no public sign-up. The app shows and stores:
- Contact details: name, email address, phone number and address — to sign you in and to let the school contact you.
- Photos and files: a profile photo and documents you choose to upload.
- Messages: messages between you, the instructor and the school office.
- Lesson information: the schedule, attendance, scores, notes and homework, and contracts you sign.
- Financial information: charges, payments and receipts with your school.
- An account identifier and, if you allow it, a device token to send you notifications.
Card numbers are never entered in the app. Online payments happen on the payment provider's secure page. The app does not collect your location, your contacts, health data or browsing history, and it contains no advertising and no analytics or tracking tools.
Data from the website
The "Request a demo" form collects your name, business name, phone, email and message. We use them only to answer your request. The site stores no cookies beyond your language choice.
How the data is used and shared
- Data is used only to provide the service: schedules, attendance, messages, billing and receipts.
- Data is never sold and never used for advertising or tracking.
- It is shared only with the services needed to run the system: cloud hosting (Google Cloud), email and SMS delivery, push notifications (Firebase Cloud Messaging), the school's payment provider, and the school's document (receipt) provider.
- Data is sent over encrypted connections (HTTPS) and kept on secured servers with daily backups.
How long data is kept
Data is kept while your school uses Maestro, and afterwards as long as the law requires (for example receipts and accounting records).
Your rights and deleting your account
You may see and correct your details in the app (Profile), and ask for a copy of your data or for your account and data to be deleted. Send the request to your school, or to us through the contact form or WhatsApp. Records that the law requires us to keep (such as receipts) are kept until that period ends.
Children
Students may be children. Their accounts are created by the school, usually with a parent's consent, and their data is used only for their lessons.
Changes
When this policy changes, the date at the top changes too.
