New in 2026: your CMP must now confirm opt-outs visibly<\/b><\/p>\n

California’s updated CCPA regulations, effective January 1, 2026, require businesses to provide visible confirmation when a user’s opt-out is processed \u2014 including when it arrives via a GPC browser signal. The California Privacy Protection Agency explicitly cites displaying “<\/span>Opt-Out Request Honored<\/b>” as a compliant method.<\/span><\/p>\n

Usercentrics CMP does this automatically. When a visitor arrives with GPC enabled, the banner is suppressed and the user sees confirmation their preference has been respected \u2014 no additional configuration needed.<\/span><\/p>\n Book a demo<\/span><\/a> <\/div>\n<\/div>\n\n\n\n\n\n

The Global Privacy Control (GPC) is both an initiative and a technical specification. Developed by a diverse group of privacy advocates, GPC promotes online privacy by creating a universal opt-out signal. <\/p>\n\n\n\n

This signal, also known as GPC, is a browser-based standard supported by organizations like the Electronic Frontier Foundation and Mozilla. Some browsers, like Firefox, Brave, and DuckDuckGo, have built-in GPC functionality. Other browsers, like Chrome, can support GPC through browser extensions.<\/p>\n\n\n\n

Usercentrics CMP supports the GPC signal for a number of regulatory frameworks and helps automate consent signaling.<\/p>\n\n\n\n

How does Global Privacy Control work?<\/h2>\n\n\n\n

Global Privacy Control<\/a> is a browser setting or extension\/plugin that enables users to communicate their privacy preferences for the collection, sharing, sale, or other uses of their personal data (like targeted advertising or profiling) to third parties. <\/p>\n\n\n\n

GPC can function as a one-stop solution for end users to manage their privacy settings, eliminating the need to repeatedly adjust preferences on different websites or online services, as is often required with cookie banners and similar tools.<\/p>\n\n\n\n

Users can set their preferences to opt in or opt out of data sharing, cookie usage, and targeted advertising. When consent is needed, and for what, varies among data privacy regulations. <\/p>\n\n\n\n

These consent preferences can be broad \u2014 full acceptance of data access and use, or basic refusal of all data access \u2014 to granular permissions for specific uses, e.g. yes to analytics cookie use, no to marketing cookies and data sales. <\/p>\n\n\n\n

While not legally binding in all jurisdictions, GPC is enforceable in regions with relevant data privacy laws, such as California and Connecticut. In other areas, GPC relies on voluntary compliance from websites and online services.<\/p>\n\n\n\n

However, GPC faces certain limitations. Not all browsers have built-in GPC functionality, some websites and apps may not be compatible with it, and compliance requirements are not the same in all jurisdictions.<\/p>\n\n\n\n

What does Global Privacy Control mean for businesses?<\/h2>\n\n\n\n

The GPC universal opt-out mechanism signifies a shift in online data privacy, even if it\u2019s not yet  required globally. <\/p>\n\n\n\n

It impacts standards and user expectations, influencing trust, brand reputation, and competitive differentiation. Businesses that collect and use personal data online should be mindful of the GPC and user preferences, not only for compliance with privacy regulations but also as a sign of respect for users\u2019 rights and personal data.<\/p>\n\n\n\n

Acknowledging the GPC signal fosters transparency and accountability, leading to stronger customer relationships and streamlined privacy operations. <\/p>\n\n\n\n

The universal GPC aligns with best practices and requirements of a number of data privacy laws, with the potential to become an international standard. Recognizing it can aid legal compliance efforts and demonstrate a commitment to best practices.<\/p>\n\n\n\n

Moreover, using the GPC contributes to a broader global standard for privacy protection, simplifying adoption and accelerating innovation. <\/p>\n\n\n\n

Respecting user privacy and data usage through clear information and user-friendly tools is a competitive advantage for growing companies, helping to enhance brand reputation to boost user engagement and long-term customer relationships.<\/p>\n\n\n\n

How Usercentrics supports the Global Privacy Control signal<\/h2>\n\n\n\n

The GPC signal is recognized by default when any of these US regulatory frameworks is in use:<\/p>\n\n\n\n

California (CCPA\/CPRA<\/a>)<\/p>\n\n\n\n

Virginia (VCDPA<\/a>)<\/p>\n\n\n\n

Colorado (CPA<\/a>)<\/p>\n\n\n\n

Connecticut (CTDPA<\/a>)<\/p>\n\n\n\n

Utah (UCPA<\/a>)<\/p>\n\n\n\n

When Usercentrics CMP receives a browser signal that GPC is in use, this logic is followed:<\/p>\n\n\n\n
