Hosted in this repository are the technical specifications for the IAB Global Privacy Protocol (GPP). The relevant specifications:

• Global Privacy Protocol String
• Consent Management API
• Data Activities and Manifests
• Supported Sections

The Global Privacy Protocol (GPP) has the objective to enable all parties in the digital advertising chain to comply with regional privacy regulations more easily. It is a transport layer that communicates user consent and preference signaling throughout the digital supply chain that supports existing consent formats and is flexible enough to support new markets with unique needs. IAB Tech Lab stewards the development of these technical specifications.

Internet users will see incremental predictability in transparency and control over time as privacy and data protection standards converge. Many more users, in countries previously uncovered by powerful digital advertising transparency and control tools, can see into and have a say over data uses for digital advertising.

Businesses will see reduced cost of maintaining privacy and data protection controls for users across the regions they work in. GPP adopters can adapt to regional changes and even gradual convergence in privacy and data protection experiences without technology switching costs.

Guiding Principles

• Reduce fragmented privacy signaling technologies that are costly for implementers
• Accommodate regional and country differences in privacy and data protection standards even if over time there is convergence
• Regions and countries should have support for their jurisdictions without needing to get other regions and countries to agree to adaptations
• Inclusive of existing in-use consent formats, recognizing that there have been a number of disparate efforts that need to be reflected
• The cost associated with adopting new privacy and data protection signaling technologies can be significant therefore we need to both minimizes costs and provide value with new features
• Flexibility is critical to support the needs of users, publishers, advertisers and the advertising technology products they use

The IAB Technology Laboratory (Tech Lab) is a non-profit consortium that engages a member community globally to develop foundational technology and standards that enable growth and trust in the digital media ecosystem. Comprised of digital publishers, ad technology firms, agencies, marketers, and other member companies, IAB Tech Lab focuses on improving the digital advertising supply chain, measurement, and consumer experiences, while promoting responsible use of data. Its work includes the OpenRTB real-time bidding protocol, ads.txt anti-fraud specification, Open Measurement SDK for viewability and verification, VAST video specification, and DigiTrust identity service. Established in 2014, the IAB Tech Lab is headquartered in New York City with staff in San Francisco, Seattle, and London. Learn more at iabtechlab.com.
