See exactly which privacy signals your browser is sending right now — the legally enforceable Global Privacy Control and the dead Do-Not-Track flag — with a plain-English verdict and instructions for turning GPC on.

Why GPC matters: Global Privacy Control tells every site you visit "do not sell or share my personal data." Unlike Do-Not-Track, it is legally enforceable: under California's CPRA, a business must treat GPC as a valid opt-out of sale/sharing, and the Colorado and Connecticut privacy laws (among others) recognize it similarly. Sites subject to those laws are required to honor it.
GPC covers "sale" and "sharing" — which, under these laws, includes most cross-context advertising. It does not, by itself, stop first-party analytics or processing you've otherwise consented to. Full background: GPC, Do-Not-Track, and consent banners.
DNT is effectively dead. It was the original "please don't track me" header, and it failed: there was never a legal requirement to honor it, almost no sites did, and major browsers have removed the setting. Whatever your browser reports above changes close to nothing in practice. GPC replaced it by fixing the fatal flaw — it attached a legal obligation to the signal instead of a polite request. Spend your effort on GPC.
Enable it, then reload this page to re-test. Settings below match our consent-signals guide.
Settings → Privacy & Security → check "Tell websites not to sell or share my data."
That single checkbox turns on both the Sec-GPC header and the JS property. Reload this page afterwards — the verdict at the top should flip to green.
Brave sends GPC by default — there is nothing to configure. If this page shows GPC off in Brave, check that Shields are enabled in Settings → Shields.
The DuckDuckGo browser and its browser extension send GPC by default.
Neither Chrome nor Edge ships a native GPC toggle. Install an extension that sends the signal — the Privacy Badger extension sends GPC, and some consent-management extensions do too.
After installing, reload this page: a GPC extension sets both the header and navigator.globalPrivacyControl, so the verdict here will reflect it.
Safari has no built-in GPC setting, and the mainstream GPC extensions target Chromium and Firefox. On Apple platforms the practical route is to use a browser that ships GPC — Firefox, Brave, or DuckDuckGo — for the browsing you want covered by the opt-out.
A few more privacy-relevant flags your browser exposes to every page. This tool deliberately does not fingerprint you: it reads only the handful of coarse flags below, renders them locally, and stores and transmits nothing.

This page proves what you're broadcasting. It can't tell you whether the sites you visit actually honor it — that requires auditing what a site collects and where it sends it. That's what ad.rip does.
