Global Privacy Control (GPC)
A browser and extension signal that communicates a user's intent to opt out of the sale or sharing of their personal information.
Full definition
Global Privacy Control is an open standard browser signal that conveys opt-out preferences under CCPA and compliant state laws. Supported by Firefox, Brave, DuckDuckGo, and extensions for Chrome and Safari. Several states (CA, CO, CT, OR, NH, NJ) legally require businesses to honor GPC. Enabling GPC provides a passive, always-on opt-out layer that complements manual deletion requests.
