The short version
Our diagnostic tools run entirely inside your web browser. Tests that use your camera, microphone, or other devices process the data live on your screen and discard it immediately. We do not upload, record, or store your test results on our servers.
Device permissions
Some tools ask your browser for permission to use hardware such as your camera (webcam test), microphone (mic and fan-noise tests), or location/network details. You are always prompted by your browser first, and you can decline. When granted, the live stream is shown only to you in the page and is never transmitted to us or anyone else. Closing or leaving the page ends the stream.
Information we collect
We do not require you to create an account or give us personal information to use the tools. We may collect standard, anonymous analytics (such as which pages are visited and general device type) to understand how the site is used and improve it.
