What happens in your browser
The practice player runs on your device. Note playback uses browser audio after you interact with the player. PDF, MIDI, and MusicXML exports are created locally; your practice notes are not sent to an upload server.
Your selected playback speed and light or dark appearance may be stored as small preferences on your device. These are not account identifiers. You can remove them by clearing this site’s browser storage. Difficulty, format, speed, and transposition may also appear in the page URL when you share a practice link.
Hosting and third parties
Fonts and illustrations are served with the site. No analytics or advertising scripts are configured in this preview. A hosting provider may process routine connection information such as IP addresses and request logs to serve and protect the website; the final hosting configuration needs Owner review.
If you follow a link to a retailer, IMSLP, Mutopia, or another external website, that service’s privacy terms apply. Clipboard access is requested only by your copy action. The player does not request microphone, camera, or location access.
Contact and future changes
A public privacy contact is not yet available. Contact details must be added before launch. This preview does not collect messages through a contact form.
The Owner must update this policy if analytics, advertising, subscriptions, or other data collection is introduced. No such features are implied by this development build.
