Global Privacy Control

Tip
Global Privacy Control (GPC) has been implemented by several browsers and extensions. GPC is a valid do-not-sell-my-personal-information signal that businesses, as of November 2025, are legally required to respect by the legislation of four U.S. states (California, Colorado, Connecticut, and New Jersey).
  • Proposed by Ashkan Soltani (Georgetown Law) and Sebastian Zimmeck (Wesleyan University) in collaboration with The New York Times, The Washington Post, Financial Times, Automattic (Wordpress.com & Tumblr), Glitch, DuckDuckGo, Brave, Mozilla, Disconnect, Abine, Digital Content Next (DCN), Consumer Reports, and the Electronic Frontier Foundation (EFF).
