What Websites Know

What this list actually is
Every page you open can read language, timezone, screen size, a GPU name, and how this machine draws a few pixels. That bundle is often called a browser fingerprint. You do not click “allow.” Incognito and a VPN do not change most of these values. They still report the same screen, GPU, and canvas print.
This tool does not guess your name or pull data-broker profiles. It only prints what JavaScript in this tab can see right now. Your IP is missing on purpose: scripts cannot read it, but the web server already has it. The scan stays here. We do not upload the dump or send it to a fingerprint service.
What is not on this list
Camera and microphone are not automatic leaks — those need a click. Test your webcam and mic before a call. A QR is another hidden string — read it before you tap. Photos leak a different kind of location. See the pin, then strip the GPS.
Longer versions: what websites can see about you without asking, does Incognito or a VPN hide this.
Browser leak FAQ
What can websites see about me?
Any site you visit can read your IP from the connection, plus JavaScript signals such as language, timezone, screen size, GPU model, hardware hints, and a canvas print. You are not asked for permission.
What does my browser know about me?
Your browser already has device and preference data so pages can render. This page dumps those same navigator, screen, and WebGL values into a terminal. It cannot see your name, email, or files.
Is this a browser fingerprint test?
It is a leak check, not a uniqueness score. The canvas line is a short hash of how this device draws text. Combined with GPU, screen, and timezone, that is the start of a fingerprint.
Does Incognito hide this?
No. Private windows clear cookies when you close them. They still report the same timezone, screen, GPU, and canvas print.
Do you store this dump?
No. The scan runs in this tab. We do not upload the report or send it to a fingerprint service.
Does this work offline?
Yes, after you have opened this tool once. That tool stays cached on this device. Other tools download when you open them.
