What this page shows
Every website you open can read a lot about your browser without asking: its user agent and client hints, your languages and time zone, your screen and hardware, your connection type and sometimes your battery. It can also see your privacy signals, such as Do Not Track and Global Privacy Control, and whether an ad blocker seems to be on. This page reads all of that in your browser and shows it in one place. Your exact location is only shown if you press the button and your browser allows it. Nothing is sent to us.
Frequently asked questions
What is my user agent?
It's the first line on this page. Support teams sometimes ask for it to find out which browser and system you use; you can copy it from here.
What is Global Privacy Control?
A signal your browser sends to say you don't want your personal data sold or shared. Brave and DuckDuckGo send it by default, and Firefox can turn it on in its privacy settings.
Why does it say an ad blocker is probably on?
The page adds an invisible box with names that ad blockers hide. If the box disappears, a blocker is likely running. Some blockers don't hide boxes like this, so "not detected" doesn't prove there is none.
