Privacy and browser limits
Most readings come directly from browser APIs and stay on your device. Operating systems, browser permissions, scaling, drivers, and hardware can affect what a page can observe.
For the cleanest result, use an up-to-date browser, keep the tab visible, and close apps that may already be using the device.
Questions about the webcam test
Is my test data uploaded?
No. This test runs locally in your browser. RatedTechTools does not receive or store the device data shown by the tool.
Does RatedTechTools record my camera?
No. The preview is rendered locally. A snapshot exists only in your browser unless you choose to download it.
Why is my camera name hidden?
Browsers commonly hide device labels until camera permission has been granted.
