About the Global Privacy Platform

The Global Privacy Platform (GPP) is part of a portfolio of solutions developed by IAB Tech Lab, as part of the Project Rearc initiative, to help the industry solve for the challenges that come with the need to address differing and evolving privacy regulations worldwide.  

The GPP is a protocol designed to streamline the transmission of privacy, consent, and consumer choice signals from sites and apps to ad tech providers; it enables advertisers, publishers and technology vendors in the digital advertising industry to adapt to regulatory demands across markets. The GPP currently supports the following privacy strings: the IAB Europe TCF, the IAB Canada TCF, the MSPA’s US National string, US states-specific privacy strings for California, Virginia, Utah, Colorado, and Connecticut. The Global Privacy Platform will continue to be expanded to support additional jurisdictions with data privacy regulations. For the most up-to-date information on supported privacy strings, see Section Information in the Global Privacy Platform github repository.
