Automatically detect and honor Global Privacy Control (GPC) signals and Do Not Sell or Share opt-out preferences.
Global Privacy Control (GPC) is a browser-based privacy signal that communicates a user's opt-out preference for the sale or sharing of personal information. ConsentX detects GPC signals and automatically applies the appropriate opt-out preference.
ConsentX checks the GPC header and JS signal on every visit.
Matching categories are set to opted-out without the visitor lifting a finger.
The opt-out is logged as evidence, the same as any other choice.
ConsentX checks both the GPC request header and the navigator.globalPrivacyControl signal on every visit. When present, it pre-applies the opt-out to the relevant categories before any tag that would sell or share data can run.
Honoring the signal silently is not enough; you have to be able to show you did. ConsentX records each GPC-driven opt-out as a tamper-evident event, so you can demonstrate compliance in an audit or a regulator inquiry.
California treats GPC as a valid Do Not Sell or Share request, and Colorado, Connecticut, Texas and others recognize universal opt-out mechanisms. Because GPC handling is built into the engine, you are covered as more states adopt the requirement without new work.
GPC works alongside the banner: you can still present choices, but a visitor who arrives with the signal set has their preference respected immediately, no clicks required.
