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 where the applicable law and provider support it. Some browsers and extensions implement it; check the current implementation and state rules for the service you are visiting. Enabling GPC can provide a passive opt-out signal that complements, but does not replace, a provider-specific deletion request.
