Privacy Policy

Effective date: October 26, 2026

This policy explains how the current version of Ear Maestro and this support website handle information. Ear Maestro is an ear-training and instrument-practice app. No account is required.

Microphone and audio

The live tuner requests microphone access to detect the pitch of your instrument. Sound is processed in temporary memory on your device. The app does not save audio recordings or upload microphone audio to the developer or a server. You can allow or revoke access in your device Settings. Listening exercises and simulated tuning use sounds generated by the app and do not require microphone access.

Training progress and preferences

Training results, stars, XP, streaks, listening-skill history, tuning errors, settings and custom tunings are stored locally on your device. They are not sent to a developer server. Reset Training Progress in Settings clears the training records. Deleting the app removes its local app data; operating-system backups, if enabled, are controlled by your Apple settings.

Purchases

Optional Pro subscriptions are processed by Apple through StoreKit. The app checks Apple-verified transaction information and subscription status to unlock features and restore purchases. Payment details are handled by Apple; the developer does not receive your card details. Apple processes information under its own privacy policy.

Advertising, tracking and analytics

The current app does not include advertising, third-party analytics SDKs, tracking across apps or websites, or a developer-operated user database. It does not request tracking permission. Registering the app in Firebase does not add Firebase Analytics or another Firebase SDK to the app.

Support and this website

If you contact the developer, the information you choose to share is used to respond to your request. Please do not send payment credentials or audio recordings containing personal information. The public website is hosted on Google Firebase Hosting. When you visit it, the hosting provider may process standard connection information, such as IP address, browser information and request logs, to deliver and protect the website. The site does not embed analytics, advertising scripts, tracking pixels or third-party fonts. Opening an external support link is subject to that service’s privacy practices.

Children and information rights

The app is for music practice and does not ask for a name, email address, age or account. The developer does not knowingly collect children’s personal information through the app. You can manage microphone permission and local records on your device. If you have shared information in a support request, contact the developer to request access, correction or deletion, subject to applicable legal requirements.

Changes and contact

Material changes to these practices will be reflected on this page with a new effective date. For privacy questions or information requests, email huanghe066@gmail.com. You can also visit the Ear Maestro support page.
