What is the Global Privacy Platform?

The GPP is designed to address a major challenge in the digital advertising industry: managing the complexities of user privacy regulations across different jurisdictions.

Here's a breakdown of what the GPP is:

  • Technical Framework: Think of it as a set of tools and protocols that websites, apps, and ad tech companies can use to communicate with each other about user privacy preferences.
  • Standardization: Instead of each company using their own method, the GPP creates a single, unified format for transmitting user consent signals. This eliminates confusion and simplifies the process for everyone involved.
  • Centralized Hub: The GPP acts as a central translator, collecting user privacy signals based on relevant regulations and converting them into a standardized format. This format is called the GPP string.
  • Collaborative Effort: The GPP wasn't built in a silo. It's the result of years of collaboration between technical and legal experts across the globe, ensuring it can handle the nuances of various privacy regulations.

In simpler terms, the GPP is like a universal language for user privacy in the digital advertising world. It allows for clear and consistent communication between different players, making compliance with regulations much easier.

The GPP simplifies compliance by acting as a central hub for user consent signals. Imagine a universal translator – companies can use any CMP (Consent Management Platform) to capture user consent based on local regulations. The GPP then transforms these signals into a single, standardized format – the GPP string. This streamlines communication across the entire digital ad supply chain.

But the GPP goes beyond just standardization. It's built with flexibility in mind. The platform supports existing mechanisms like the US Privacy and IAB Europe TCF consent strings, and can readily incorporate new regulations as they emerge.

Additionally, the GPP integrates with the Global Privacy Control (GPC), a browser-level setting that allows users to opt-out of data sharing altogether.

How is the GPP different from the IAB EU’s TCF?

The IAB Tech Lab's Global Privacy Platform (GPP) and the IAB Europe's Transparency and Consent Framework (TCF) v2.0 share some similarities, but there are also key differences that impact how they are used:


  • GPP: Global in reach. The GPP is designed to handle user consent signals from a wide range of jurisdictions, including the US (CCPA, state-specific laws), Europe (GDPR), and potentially future regulations from other regions.
  • TCF v2.0: Primarily European Focus. The TCF v2.0 was specifically developed to address the nuances of the European Union's General Data Protection Regulation (GDPR).


  • GPP: Standardization and Flexibility. The GPP's primary focus is providing a standardized format (GPP string) for transmitting user consent signals across different jurisdictions. It's also built to be adaptable, allowing for easy integration of new privacy regulations as they emerge.
  • TCF v2.0: Granular Consent Management. The TCF v2.0 goes beyond just standardization. It offers a more granular approach to consent management, allowing users to express specific preferences about how their data is used (e.g., for personalization, location tracking).

Future Outlook

  • GPP: Evolving Standard. The GPP is a relatively new initiative, and its future development will depend on industry adoption. However, its broader scope and adaptability position it as a potential future standard for global user consent communication.
  • TCF v2.0: Continued Relevance in Europe. The TCF v2.0 is expected to remain relevant within the European market, especially for companies that need to comply with the specific requirements of GDPR.

In essence, the GPP acts as a broader umbrella that can accommodate the TCF v2.0 framework within its structure. While the TCF v2.0 will likely remain relevant in specific contexts, the GPP is expected to become the preferred solution for companies navigating the complexities of global privacy regulations.

How does the GPP affect the TCF v2.0 framework?

The GPP is designed to be the future of user consent communication, and while it won't eliminate the TCF v2.0 framework entirely, it will likely have a significant impact in a few ways:

  • Reduced Reliance on TCF v2.0: The GPP offers a broader scope, encompassing not just the IAB Europe's TCF v2.0 but also US-specific regulations like CCPA and potentially future frameworks from other regions. This means companies that need to consider user consent signals across multiple jurisdictions will likely favor the GPP for its all-encompassing approach.
  • Continued Support: Despite the rise of GPP, the TCF v2.0 is still expected to be available and supported by the IAB Europe. This is because the TCF v2.0 specifically addresses the nuances of European privacy regulations like GDPR. Companies solely operating within the European market may find the TCF v2.0 sufficient for their needs.
  • Future-Proofing with GPP: The GPP is designed with flexibility in mind. It can be easily updated to incorporate new privacy signals and regulations as they emerge. This makes the GPP a more future-proof solution compared to the TCF v2.0, which may require more specific updates to adapt to evolving regulations.
  • TCF v2.0 Integration: The IAB Tech Lab has indicated that the GPP will continue to reflect changes made to the TCF v2.0 framework. This ensures that companies already familiar with the TCF v2.0 won't be completely lost when transitioning to the GPP.

In essence, the GPP is like a broader umbrella that can accommodate the TCF v2.0 framework within its structure. While the TCF v2.0 will likely remain relevant within the European market, the GPP is expected to become the preferred solution for companies navigating the complexities of global privacy regulations.

How does GPP affect the Global Privacy Control?

The IAB Tech Lab's GPP and the Global Privacy Control (GPC) work hand-in-hand to empower user control and streamline privacy compliance in the digital advertising industry. While the GPC itself isn't a legal requirement, it offers a powerful user-driven mechanism for opting out of data sales for advertising purposes. The GPP plays a crucial role in amplifying the effectiveness of the GPC.

Imagine a user who activates the GPC in their browser settings. This essentially sets a "Do Not Sell" flag on their data. Previously, this signal might not have been understood or interpreted consistently across different ad tech platforms. The GPP acts as a bridge, seamlessly integrating with the GPC. When a user activates the GPC, the GPP framework captures this signal.

Here's where standardization comes into play. The GPP translates the GPC opt-out signal into a common language – the GPP string. This standardized format ensures that all participants in the digital advertising ecosystem, from publishers and advertisers to ad tech vendors, can clearly understand the user's privacy preference.

This clear communication benefits everyone involved. Users gain confidence knowing their opt-out choice is transmitted effectively. Publishers and advertisers can easily identify users who have opted out via GPC, ensuring they comply with user preferences and avoid potential legal ramifications. Ad tech vendors also benefit from the streamlined process. The GPP string provides a clear understanding of user consent signals, allowing them to deliver targeted advertising while respecting user choices.

The GPP acts as a translator and facilitator, strengthening the impact of the GPC. While the GPC empowers users to control their data, the GPP ensures this control is effectively communicated and respected throughout the complex web of the digital advertising landscape.

What is the Multi-State Privacy Agreement (MSPA)?

The Multi-State Privacy Agreement (MSPA) is an industry agreement, not a legal document, designed to help companies comply with several new state privacy laws in the United States. It works in conjunction with the GPP. Here's a breakdown of the key points:

  • Purpose: The MSPA simplifies compliance with a growing number of US state privacy laws, particularly those enacted in 2023 (California, Virginia, Colorado, Connecticut, and Utah).
  • Focus: It establishes a set of standardized contractual terms related to privacy that apply when personal information is shared for online advertising purposes. These terms are designed to align with the requirements of the aforementioned state privacy laws.
  • Function: Think of it as a pre-written contract that automatically applies when companies involved in the digital ad supply chain (advertisers, publishers, agencies, technology vendors) are signatories of the MSPA. For companies that don't have separate commercial agreements, the MSPA provides a baseline for privacy compliance.
  • Benefits: The MSPA aims to streamline compliance by offering a standardized approach across multiple state laws. This reduces the need for companies to create custom solutions for each individual state, saving time and resources.
  • Relationship with GPP: The MSPA works hand-in-hand with the GPP. The GPP provides the technical framework for transmitting user consent signals in a standardized format across different jurisdictions. The MSPA ensures these signals are used appropriately and companies comply with relevant privacy laws.
