We only collect data that is necessary for the service to work:

• User-generated content — drum patterns you save, your preferences (BPM, theme, note division), and beats you mark as favorites.
• Analytics data — page views, session duration, and general interactions collected by Google Analytics via browser cookies. This is only activated after you give consent.

We do not collect payment information, precise location, or any sensitive personal data.

• To provide and operate the drum sequencer and your account.
• To save and retrieve your patterns, preferences, and favorites across devices.

We do not sell your data, run advertising, or use your data for any purpose beyond operating this service.
