Privacy

No account. No tracking cookies. Nothing captured from your camera, microphone, screen, location or sensors ever leaves your device.

What the tests do with your data

Every test runs in your browser. Camera and screen frames are rendered in your own tab and discarded when you stop. Microphone audio is fed to a Web Audio analyser to draw a waveform; a recording you make is held in memory and dropped when you leave the page. Location, motion and Bluetooth readings are displayed and never transmitted. There is no server-side code that receives any of it, which you can verify in the repository.

What is stored on your device

Local storage holds your colour theme, your keyboard layout choice, and your own scores for the click, scroll and reaction tests. You can clear it from within each test or by clearing site data. It is never sent anywhere.

What the server sees

Ordinary web server request logs: the page requested, a timestamp, and the request headers your browser sends. The network test additionally transfers a block of random bytes in each direction so it has something to measure; the contents are generated on the spot and discarded.

Third parties

None. No analytics, no advertising, no fonts or scripts loaded from anyone else’s server.

The desktop app

The desktop build makes no network request at all unless you run the network test. It does not check for updates in the background and it has no telemetry.
