What you leak

Everything below is read live, in your browser, the moment this page loads. It's the same information any website you visit can see about you — shown back to you, with what each item means and how to reduce it.

Nothing here is stored or logged. The one piece that needs a server — your IP and network location — is answered by a function that reflects it back and immediately forgets, with caching disabled. Don't trust that? Open your browser's network panel and watch: this page makes zero third-party requests.

JavaScript is off — and honestly, good for you.

Most of the checks on this page need JavaScript to run, so they can't show you anything right now. That's the point: with scripts disabled, you've already shut off canvas fingerprinting, WebRTC leaks, and most of the browser probes advertisers rely on. Plenty of privacy-minded people browse exactly like this.

Your network-level exposure (IP address and the rough location derived from it) is visible to every site regardless of JavaScript — turn scripts on briefly if you want to see it, or read the browser hardening guide to lock things down further.
