Protecting privacy online

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 technologies are currently in development. You can learn more about the proposals on Google for Developers. Google welcomes members across the industry to provide feedback or start testing. This site will also be updated monthly as the initiative progresses.

New web and app technologies are needed to improve people's privacy online. In recent years, some browsers and platforms have taken steps to restrict or remove existing mechanisms, such as third-party cookies, without effective alternatives in place. This can negatively impact critical ecosystem functionality and put user privacy at greater risk, by leading to adoption of covert tracking.

We believe that developers and businesses should be able to make money from their sites and apps, as well as reach customers with relevant ads. The Privacy Sandbox initiative is developing new solutions that support key ecosystem needs -- without reliance on online tracking identifiers -- so that publishers and developers can provide free content and grow their business in a privacy-preserving way.

Google invites members from the industry—web browsers, online publishers, ad tech companies, advertisers, and developers—to participate in the development and testing of the proposed new technologies.

For the open web, you can contribute to the public discussions in forums such as the W3C, and if you’re a business, talk to your trade groups and technology vendors about engaging in this process. If you’re a developer, we invite you to join the origin trials.

For Android, feedback on the design proposals can be given via the Google for Developers site. This is also where you can sign up for regular updates as the project progresses.

You can expect to hear more about the progress being made with Privacy Sandbox regularly, including more opportunities for you to test these new technologies on your sites and in your campaigns. For the latest news, follow our News & Updates and the blog on Google for Developers.

Please fill this form if you would like for a Privacy Sandbox representative to speak at an event. Your responses will be reviewed the first week of each month and a decision on attendance will be communicated to you no later than the 15th of each month.

The Chromium blog regularly features progress updates on Privacy Sandbox. Google for Developers offers a good overview of all Privacy Sandbox proposals and refers to explainers and discussions on GitHub.
