Global Privacy Control

Global Privacy Control (GPC) is a set of web technologies that can be used to inform websites of the user's wish to have their information not be sold or used by ad trackers. Unlike the now-deprecated Do Not Track header, which was unsuccessful as it was ignored by third parties, GPC is intended to have legal force under privacy laws.

GPC was developed in 2020 by privacy technology researchers including Wesleyan University professor Sebastian Zimmeck and former Chief Technologist of the Federal Trade Commission Ashkan Soltani, as well as a group of privacy-focused companies including the Electronic Frontier Foundation, Automattic (owner of Tumblr and WordPress), and more.
