Account and personal state
The studio stores a username, password hash and chosen display name. Player preferences, learning state, favourites and activity are associated with your account. Passwords are not stored as plain text.
Cookies and browser storage
Session and CSRF cookies support sign-in and request security. Language, theme and some playback preferences may also be stored in the browser. Application files and piano samples are cached for offline use.
Activity statistics
Statistics count time while the site is visible or the player is playing. Active visits of at least five minutes are included. This is not an automatic assessment of your physical piano performance.
Hosting and public pages
Cloudflare delivers the site. The server keeps standard request logs for security and troubleshooting. Google Search Console measures the visibility of public pages in search; private studio records are not included in the sitemap.
