The Privacy Sandbox on Android aims to develop new technologies that improve user privacy and enable effective, personalized advertising experiences for mobile apps. We welcome industry feedback on the design proposals, and encourage testing as both Developer Preview and Beta releases become available.

People should be able to enjoy their app experience without worrying what personal information is collected, and by whom. The Privacy Sandbox on Android aims to build solutions that do not rely upon current tracking mechanisms, and block covert tracking techniques, such as fingerprinting.

Enable publishers and developers to keep online content free

Publishers and developers need innovative, privacy-preserving alternatives for their key business needs, including serving relevant ads, in order to continue providing free experiences for billions of people around the world.
Android has a long history of open source collaboration. We invite the entire ecosystem to be involved and contribute to the development of better user privacy standards for apps.
Privacy Sandbox on Android offers two programs to help ad tech platforms and app developers design, test, and prepare for future production rollouts to users.
Get started
Developer programs
Use the Developer Preview program to conduct initial testing of proposed APIs, evaluate how to integrate them with your solutions, and provide feedback. We’ll introduce new APIs and features in this program over time and promote stabilized APIs to the Beta program.
Developer programs
Use the Beta program to integrate your solutions with stable APIs for production testing on a limited number of Android 13 devices, which will increase over time. The Beta release is delivered via the Ad Services Extensions 4 release, a new mechanism for delivering production ready features between major Android releases.

Proposed Solutions

Android will introduce new platform features that support mobile advertising while enhancing user privacy. You can review the current proposals for each of these features and provide feedback to help improve them.
