Overview
Solfege PRO has no account registration. The app does not collect personal information such as your name or email address.
Information We Collect
Usage Data
To improve the app, we collect anonymous usage events via Google Firebase Analytics: which screens and trainings are used, practice statistics such as accuracy, plus device model, OS version, app version, and language. This data does not identify you personally.
Crash Reports
To fix defects, we collect crash reports via Firebase Crashlytics.
Microphone
The microphone is used only to detect claps and taps in rhythm trainings. Audio is processed on your device — it is never stored as a recording or sent to any server.
Purchases
Payments are processed by Apple. We never have access to your payment details, such as credit card numbers.
Contact Form
Anything you submit through the contact form (including any contact details you choose to provide) is used only to respond to your inquiry.
Data Deletion & Questions
For data-deletion requests or questions, please use the contact form below. Deleting the app erases the data stored on your device. Firebase identifiers are reset when the app is reinstalled.
