Privacy Notice

This website is designed to test as many browser features as possible. This includes features that access sensitive information, such as microphone, camera, geolocation, etc. No audio/video, geocoordinates, browser history, or other personal info is recorded, stored or transmitted. Only two pieces of information that identify your browser configuration are recorded: your browser's user agent string, which includes data about your operating system and browser version; and installed extensions from a set list of extensions known to cause compatibility testing issues.

Cookies are used for session tracking, so that test results can be stored on the server and then optionally exported. Cached test results are cleared regularly.
