What happens during a test
Every test on this site runs inside your web browser. When a test uses your microphone, camera, motion sensors, controller, keyboard, mouse or screen, that information is processed on your device and shown back to you. It is not uploaded, recorded or stored by us.
- Microphone and camera are only switched on after you press a start button and your browser asks for permission. They switch off when you stop the test or leave the page.
- Voice recordings and snapshots stay in your browser's memory until you download them or close the page. We never receive them.
- Permissions you grant are managed by your browser, and you can remove them at any time from the site settings (usually the icon next to the address).
What is saved on your device
A few tools remember small settings in your browser's local storage, so they're still there next time. This data never leaves your device:
- Your best scores on the click speed test, spacebar counter and reaction time test.
- The calibration setting on the noise meter.
You can delete it at any time by clearing this site's data in your browser settings. We don't use cookies.
What our web server sees
Like any website, the server that delivers these pages receives basic technical information whenever a page loads, such as your IP address, browser type and the page requested. Hosting providers typically keep this in short-term logs for security and to keep the site running. We don't use it to identify you.
The connection test also requests a tiny image from this site once a second while it runs, to time the reply. Those requests carry no personal information beyond the technical details above.
What we don't do
- No accounts or sign-ups.
- No selling or sharing of personal information.
- No analytics, advertising or tracking scripts at present. If that changes, this page will be updated first.
Children
The site doesn't knowingly collect personal information from anyone, including children.
Changes to this policy
If the way the site handles data changes, this page will be updated and the date at the top will change.
