For analytics, advertising, and consent management, cookies or similar technologies may collect information such as device and browser information, visited pages, referrer, approximate location, and interaction data.

Rhythms, time signatures, tempo, and swing settings that you enter are displayed and played back in your browser. We do not provide an account-based feature that stores this information for you.

When you create a shared link, the rhythm, time signature, tempo, and swing settings are included in the URL query parameters. If you send or publish a shared link, anyone who receives the URL can view the rhythm data contained in it.
