FAQ

What can this tab see without a click?

The screen size, the browser name, the user-agent string, the language, the time zone, and the color scheme. The IP address waits for the button.

What does this column refuse to read?

No city, no WebRTC connection, no canvas, fonts, GPU, or battery, and no fingerprint hash.

Is anything saved?

No. The readings stay in this tab. The IP response is not written to a database.

Why does the IP address wait for a click?

The address is requested only when you ask, and it is not stored.

How do the pages differ?
