Global Privacy Control (GPC)

The Global Privacy Control (GPC) is a formal specification of the "opt-out preference signal" referenced in CCPA regulations and CPRA.

The Attorney General of California has declared support for the Global Privacy Control (GPC) signal, and has already begun enforcing non-compliance with it.

Transcend Consent automatically detects the Global Privacy Control signal and opts users out of the sale and sharing of their personal information.

When a user has the GPC signal enabled, the Consent Manager interface will also confirm to the user that their signal has been detected, and they have been automatically opted out.
