Is the information shown by this tool sent to a server?

Information such as your browser type, size, language and GPU is collected and displayed entirely within your own browser and is never sent to our servers. Only your IP address is retrieved by sending an HTTP request to an external IP information service (ipapi.co) in order to display it.

What is a User Agent?

A User Agent is a string that a browser sends to a web server to identify its own type, version, operating system and so on. It is used for browser detection and for checking compatibility.

What is the difference between screen size and window size?

Screen size refers to the full resolution of the display, while window size (viewport) refers to the area the browser actually uses for rendering. When you shrink the window, only the latter changes.
