MaestrPlay privacy policy

Information we collect

Account information

Your email address, the display name you choose, and your password. Passwords are handled by our authentication provider and stored only in hashed form; we cannot read them.

What you tell Mai

The messages you send in conversations with Mai and the replies she gives.

Your learning profile

Your instrument, skill level, goals, preferences, and notes Mai keeps so she can remember you between sessions — for example what you are working on and how recent practice has felt.

Practice activity

Practice sessions, streaks, skill progress, badges, and your reminder time.

Push notification token

If you allow notifications, a token that lets us send practice reminders to your device.

Usage data

Events such as starting a session, sending a message, or extending a streak, together with basic device information (device model, operating system version, app version). These are tied to a scrambled (hashed) version of your account ID rather than your email or name.

Crash and error reports

Technical details of crashes and errors, tied to the same hashed ID. Your email address is removed from these reports.

Microphone and audio

MaestrPlay asks for microphone access once, during setup, to show a sound-level meter. The sound is measured on your device only. Audio never leaves your device: we do not upload it, and we cannot access it.

If a future version processes audio in any other way, we will update this policy and ask for your consent in the app first.

How we use information

• To run the app: sign you in, save your progress, and send the reminders you ask for.
• To generate Mai’s replies and tailor her coaching to you.
• To understand how the app is used and to find and fix problems.

We do not sell your information, show you advertising, or track you across other companies’ apps and websites.

AI processing

Mai’s replies are generated by AI. When you send a message, that message, relevant earlier conversation, and your learning profile are sent to Dawn, an AI gateway we operate, which passes them to a third-party AI model provider to produce the reply. We send this content only to generate Mai’s responses and to keep her memory of you up to date.

Mai is a practice coach, not a person, and her replies can be wrong. Please do not share information in conversations that you would not want processed this way.

Sending account emails such as password resets

We may also disclose information if the law requires it. These providers may process information in countries other than the one you live in, including the United States.

Retention and deletion

We keep your information for as long as you have an account. To delete your account and the information associated with it, email support@burgundysoft.io from the email address on your account; we will delete it within 30 days. Analytics and crash data tied to a hashed ID may remain in aggregated form that no longer identifies you.

Your choices

• You can turn practice reminders and notifications off in Settings or in your device settings.
• You can withdraw microphone access at any time in your device settings.
• You can ask us for a copy of your information, or to correct or delete it, by emailing us.

Children

MaestrPlay is not directed to children under 13, and we do not knowingly collect information from them. If you believe a child has given us information, contact us and we will delete it.

Security

Information is encrypted in transit. Sign-in tokens are kept in your device’s secure storage. No system is perfectly secure, and we cannot guarantee absolute security.

Changes to this policy

We will post any changes here and update the effective date. If a change is significant, we will tell you in the app.
