Global Privacy Control (GPC) is a privacy setting that allows users to set their browser to automatically signal to websites and online services that they do not want their personal information to be sold or shared with third-party companies. It is a simple and standardized way for users to exercise their privacy rights and opt-out of data-sharing practices.

When users activate GPC, their browser sends a signal to websites and online services they visit, indicating that the user wants their personal information to be kept private. This signal is a header included in the browser's HTTP request, and it can consist of a digital "do not sell" instruction that tells websites not to sell the user's personal data to third-party companies.

GPC Signal and CCPA

As new legislation focused on data privacy and protection becomes law, it is increasingly important for businesses to respect and honor GPC signal. This is essential for CCPA compliance and for demonstrating to site visitors that privacy rights are taken seriously. By adhering to GPC signal guidelines, businesses can show their commitment to respecting and safeguarding each user's privacy while also ensuring that personal data is collected and used ethically and in compliance with applicable laws and regulations.

As CPRA became effective January 1, 2023, the AG of California is stepping up enforcement of this legislation to make sure that every business responsibly handles and respects each user's data privacy. Recent enforcement of CCRA levied massive fines for the online retailer Sephora.

"There are no more excuses. Follow the law, do right by consumers, and process opt-out requests made via user-enabled global privacy controls" - Office of the AG of California
