What this page can tell about your browser

A test page. Everything it works out about your device is listed below — nothing is collected that you cannot see here.

What this is. This page runs analytics code that identifies your device from its browser and hardware characteristics, then stores what it finds. It is being tested, and you were sent this link deliberately. Everything it collects is shown to you on this page in full. Close the tab to stop it; nothing runs afterwards.

How you are identified

waiting for the first beacon…

What your connection reveals

asking the server…

These are not read by the code running in your browser — a page cannot see its own IP address. They come from the network connection itself and are added by the server on arrival, which is why they are listed separately from everything above.
The visitor id is stored in a cookie this page cannot read, only the server can. It is the value that persists longest: if you come back next week and the device id above has changed while this one has not, your browser cleared its storage and the cookie survived.

Reloading is worth doing: it shows which values stay the same, which is what makes a device recognisable on a later visit.
