About Browser Info Viewer
Browser Info Viewer is a free online tool that lets you check all kinds of information about the browser you are currently using, gathered together on a single screen. It lists your browser type and version, OS, screen and window size, IP address, language, time zone, GPU, network status and more. It is handy for testing, troubleshooting, support work and debugging during development.

About privacy
All browser information is collected and displayed entirely within your own browser and is never sent to or stored on our servers. The camera and microphone are only checked for existence; they are never activated, recorded or captured, and no permission dialog is shown. Only your IP address and estimated region are retrieved by sending a request to an external IP information service (ipapi.co) in order to display them.
