What is Privacy?
This tool shows whether your browser is sending a Do Not Track (DNT) request, which asks websites not to track your activity. It also reports your Global Privacy Control (GPC) signal, a newer privacy preference that carries legal weight in some regions.
How Privacy works
It reads navigator.doNotTrack (and the older window.doNotTrack / navigator.msDoNotTrack). A value of 1 means DNT is on, 0 means off, and null means no preference is set. GPC is read from navigator.globalPrivacyControl.
Honouring DNT is voluntary, so many sites ignore it; GPC is enforced by law in some places.
Common uses
- Check if Do Not Track is turned on
- Confirm your Global Privacy Control (GPC) signal
- Verify a privacy setting after changing it
- Understand what tracking preference sites receive from you
Frequently asked questions
Is Do Not Track enabled?
The status at the top shows ON, OFF or Not set, read directly from your browser.
Does Do Not Track actually stop tracking?
Not on its own — it's a request that sites can ignore. For stronger control use GPC, privacy extensions or browser tracking protection.
What is Global Privacy Control (GPC)?
A newer 'do not sell or share my data' signal that, unlike DNT, is legally enforceable in some regions such as parts of the US.
