Your inputs never leave your device. Keystrokes, mouse events, microphone audio, camera video and controller state are processed in your browser to draw the instruments and are never transmitted, recorded or stored by us. Close the tab and they are gone.

What we do measure: anonymous page analytics (Google Analytics with IP anonymization plus our own first-party page counter): pages visited, country, device type, and anonymous events such as "a keyboard test was completed". None of it identifies you or contains your test data.

Advertising: if ads appear, ad partners may use cookies subject to their own policies; ads will never sit inside the test surfaces.

To remove everything this site knows: clear this site's data in your browser settings.
