Global Privacy Control (GPC): Honor Opt-Out Signals Automatically
A growing list of US state laws require you to honor GPC. ConsentPixel detects and respects it automatically — and logs every signal.
Global Privacy Control (GPC) is a browser-level signal that lets people broadcast a "do not sell or share my data" preference to every site they visit. A growing number of US state privacy laws require businesses to honor it. ConsentPixel — Privacy · Verified detects and respects GPC automatically — and logs every one — so your site meets universal opt-out obligations without manual work.
What is Global Privacy Control?
Global Privacy Control is a technical specification that sends a standardized opt-out signal from a visitor's browser or extension to the websites they visit. Instead of clicking "do not sell my personal information" on every site, a person enables GPC once and their preference travels with them.
GPC is not itself a law — it's the mechanism that several laws point to as a valid "universal opt-out mechanism." Under the CCPA/CPRA in California, and under laws in Colorado, Connecticut, Texas, Montana, Oregon, and others, businesses must treat a GPC signal as a legally valid opt-out of the sale or sharing of personal data and of targeted advertising. Ignoring GPC where it's required is a direct compliance failure.
Where honoring GPC is required
- California (CCPA/CPRA): Businesses must treat GPC as a valid opt-out of sale/sharing; enforcement actions have specifically cited failure to honor it.
- Colorado, Connecticut, Texas, Montana, Oregon, and more: These laws require recognition of universal opt-out signals, with GPC the de facto standard.
- Growing list: Newer state laws increasingly mandate universal opt-out recognition, often on a defined effective date.

Frequently asked questions
Does ConsentPixel honor GPC signals automatically?
Yes. ConsentPixel detects the GPC signal on page load and applies it as a valid opt-out of sale/sharing and targeted advertising wherever state law requires recognition of universal opt-out mechanisms.
Is honoring GPC legally required?
In several states, yes. California's CCPA/CPRA and laws in Colorado, Connecticut, Texas, Montana, Oregon, and others require businesses to treat a recognized universal opt-out signal as a valid opt-out. GPC is the prevailing standard.
What happens to my ad tags when a visitor sends GPC?
ConsentPixel suppresses or signals your advertising and analytics tags so they don't sell or share that visitor's data or serve targeted advertising, consistent with the opt-out.
Does GPC replace my consent banner?
No. GPC handles opt-out automatically for visitors who enable it, while your banner still governs consent for everyone else and for opt-in jurisdictions. ConsentPixel keeps the two consistent.
Can I prove I honored a GPC opt-out?
Yes. ConsentPixel records every GPC signal received and the action taken in immutable, tamper-evident, audit-ready logs.
