Privacy
How this site handles files, saves preferences and uses optional analytics.
HomeFiles stay in your browser
Selected images are processed on your device. This site does not send selected files, their contents or musical input to analytics. Working data leaves page memory when you close it.
Preferences on your device
Your browser can store theme, text size, effects, appearance and physics-display preferences. Practice scores exist only on the open page. You can remove saved preferences through your browser's site-data settings.
Optional analytics
Yandex Metrica is disabled in this version: its external script is not loaded and no analytics events are sent. Preferences and tools work independently.
Music sections
Analytics is completely disabled throughout the music sections, including when adult appearance is selected. This restriction follows the purpose of a section, not its interface appearance.
How to withdraw
When analytics is available, select Do not allow in the settings below. Your choice stays in this browser until changed or site data is cleared, and applies only to the specified counter. Withdrawal stops further sending, including from other open tabs of this site. It does not delete previously sent data or Yandex cookies; you can delete cookies in your browser settings.
Yandex also offers a Metrica browser blocker.Loading this site
Your browser contacts Yandex Cloud hosting to load the site. The hosting service receives technical HTTP-request information, including IP address. Disabling Metrica does not remove these network data.
