- Theme, language, note-naming, sound and practice preferences.
This information is used only to provide app features. It is not uploaded to SynoriTech. The app keeps no trial or purchase records.
Microphone
Answering on your own piano is optional. The app asks for microphone access only when you switch that input on, and it analyses the sound in real time on your device to identify the note you played. Audio is never recorded, saved or transmitted. You can revoke the permission in iOS Settings at any time; the on-screen keyboard keeps working without it.
Purchase
This is a one-time paid download. Apple processes the App Store purchase, eligible re-downloads and refunds under its own terms. SynoriTech does not receive payment-card details. There are no in-app purchases, subscriptions or trials.
Export, homework codes and sharing
When you export your practice data, the app creates a JSON backup and hands it to the iOS share sheet; it leaves the app only after you choose a destination, and the temporary file is deleted when sharing ends. Homework codes use the system clipboard only when you choose to copy or paste them. The privacy practices of the destination you choose then apply.
What we do not do
No account creation, analytics or crash-reporting SDK, advertising identifier, advertising, tracking, data broker sharing, or cloud storage operated by SynoriTech.
Retention and deletion
Settings → Your data → Reset progress erases every practice attempt, session result, star and streak after a double confirmation; theme, language and practice preferences are kept. Homework assignments are deleted one by one from their own screen. Quiz high scores and preferences are removed when you delete the app. Backups you exported and text you copied are under your control. Because there is no account or server copy, SynoriTech cannot recover deleted information.
Website hosting
This page is hosted by GitHub Pages. GitHub may process basic technical information when you visit it under the GitHub Privacy Statement. SynoriTech does not add analytics or advertising to this page.
Changes and contact
We may update this policy when the app changes; the effective date above is the current version. Questions can be sent to support@synoritech.com.
