Google’s Privacy Sandbox aims to improve web privacy for people around the world, while also giving publishers, creators and other developers the tools they need to build thriving businesses. Since announcing the Privacy Sandbox we have been in open dialogue with the industry, consumer advocates and regulators to gather feedback on this initiative.
The Privacy Sandbox is an industry-wide effort to develop new technology that will improve people’s privacy across the Web and apps on Android. The proposed solutions will limit tracking of individuals and provide safer alternatives to existing technology on these platforms while keeping them open and accessible to everyone.
The Privacy Sandbox: Technology for a More Private Web.

Respecting user privacy while maintaining a well functioning ad-funded web
Google’s objectives in developing the Privacy Sandbox proposals are to make the web more private and secure for people, while:
- Supporting the ability of publishers to generate revenue from advertising inventory and the ability of advertisers to secure value for money from advertising spend;
- Supporting a good user experience when navigating the web, including in relation to digital advertising;
- Providing users with substantial transparency and control in relation to their data as they browse the web; and
- Not distorting competition between Google’s own advertising products and services and those of other market participants.
Developing the Privacy Sandbox
To achieve the objectives above, Google is committing to designing, developing and implementing the Privacy Sandbox proposals taking into account specific criteria agreed with the CMA:
- The impact on privacy outcomes and compliance with privacy laws;
- The impact on competition in digital advertising between Google and other market participants, and, in particular, the risk of distortion to competition;
- The effect on publishers (including their ability to generate revenue from ad inventory) and advertisers;
- The impact on user experience (e.g. relevance of advertising and transparency over the use of personal data); and
- The technical feasibility, complexity and cost involved for Google.
