Global Privacy Control (GPC) is a specification that enables users to express their preference to opt out of data tracking and sharing across websites via a browser setting or an extension. It’s designed to enhance user privacy by automatically communicating this preference to websites in compliance with data protection regulations like GDPR and CCPA. For more details, visit official GPC website.
Tip
To better understand data privacy regulations, see Adform Academy course Understand Evolving Privacy Regulations.
Once a user enables the GPC setting in their browser (or uses an extension), the GPC signal is included in each request sent to Adform on websites that have implemented GPC. This setting communicates the user’s choice to opt out of data tracking and sharing.
Adform receives a GPC signal through an HTTP request in the form of an HTTP header. This preference is represented by a value of 1
or true
, depending on the context. For more information, see GPC specification. Upon receiving the signal, Adform processes it as if the user has opted out, ensuring their privacy preferences are respected.
If you're using server-side tracking, make sure your setup is configured to detect a GPC signal that the GPC HTTP headers are forwarded within your server-side tracking request.
