Browser Privacy Check

A single-file, dependency-free tool that shows the signals your browser exposes to every website: user agent, languages, time zone, screen, hardware hints, Do Not Track / Global Privacy Control, and more.

Honesty by design

• 100% client-side. Nothing is uploaded, stored or shared. Open the network tab and check.
• No fake uniqueness score. Telling you how unique your fingerprint is requires comparing it against a large server-side dataset. This tool doesn't have one, so it doesn't pretend to.
• DOM-safe rendering. No innerHTML; all output is rendered with createElement/textContent.

What it reads

Only standard APIs available to any page: navigator.*, screen.*, Intl.DateTimeFormat().resolvedOptions(), and matchMedia preference queries. No canvas hashing, no WebGL probing, no font enumeration.

Usage

Open index.html in a browser. That's it - no build, no dependencies.
