What You Already Leak
This is an example of what this page, and every other page on the internet, can already see about you the moment it loads. We're not hacking you or pulling anything hidden — this is data you're already leaking to the public on every site you visit. We're just the first one to show it back to you.
This site is static — we don't store what you see below, and we don't need to. But ad networks, data brokers, and the kind of bulk-collection infrastructure covered in the Field Manual (XKeyscore, Palantir) are built entirely on data exactly like this.
What this page can see, right now
Not from hacking anything — this is handed over automatically by your browser and network on every single site you visit, including this one:
Checking…
Location is approximate (city-level, from your IP) — not your address. We don't store this. We don't need to — this loads live, every time, on any site.
Your device fingerprint
Your IP can change. This mostly can't — this is how ad networks and trackers recognize you again even after you clear cookies or switch networks. — data points, just from opening this page.
Reading your device…
All computed locally in your browser, right now — nothing here is sent anywhere or stored by us.
Two more checks — read this first
Below are two separate, unrelated tools — not a login form. We never ask for both together, never combine what you type into them, and never see the two side by side. If you don't trust either one, don't type anything real into it — use a fake email or a password you don't actually use anywhere, both checks work exactly the same either way.
Checked live against a free, public breach-monitoring database — no signup, no cost, nothing stored on our end. This tool never touches the password check below.
Your password is never sent anywhere, full stop. It's hashed in your browser and only the first 5 characters of that hash leave your device (k-anonymity) — nobody, including us, can reconstruct the real value from that. This tool never touches the email check above.
