Self-fingerprint inspector other environment
The signals a tracker could read to identify your browser, shown only to you and computed only here.
What 'other' means here
This tool lives in the green room because its input is your BROWSER AND DEVICE — the output legitimately differs for every visitor, so there is no fixed correct answer for golden vectors to assert. It is the privacy thesis made visible.
Click below and this page computes, in your browser, the signals a fingerprinting script would read. Nothing is sent anywhere — the result is shown only to you.
Every signal is computed in your browser and displayed here only. Nothing is uploaded, stored, or compared against anyone else.
Fingerprinting does not need cookies. A script can combine your user agent, screen geometry, installed fonts, and the exact way your GPU renders a hidden canvas into an identifier that follows you across sites without any stored ID. This tool computes those same signals so you can see the surface for yourself.
Everything here runs locally and is shown only to you; nothing is uploaded or retained. It is a companion to the passive-fingerprint work on the main site, made concrete: the clearest way to understand a tracking surface is to look at your own.
