A web page that tells you what your browser gave away the moment you arrived. No login, no form, no permission. Most pages do this. None of them tell you.
This specific website only shows information that the browser is freely offering. Basically you open the page, and without the website even asking for anything, that’s the information it’s getting. It’s not querying any data points, or trying to tie any of them together. This is just your browser saying “Hi, we just met, so here’s a bunch of stuff you may want to know about me.”
If they want to know more, they can just ask and the browser will give more information. If there’s information the browser doesn’t want to share, the website can infer a bunch more information.
