Frequently asked questions

Are these tests free?

Yes. Every test on CheckMyGadget is free, with no signup and no download.

Is my camera, microphone or keyboard input recorded?

No. All tests run inside your browser. Audio, video and key presses are never uploaded, recorded or stored.

Which browsers work?

Current versions of Chrome, Edge, Firefox and Safari. Camera and microphone tests need a secure (https) connection and your permission.

Why can't the site see some keys, like brightness or volume?

Operating systems handle those special keys before the browser sees them, so no website can detect them.
