Privacy Sandbox on Android Developer Preview is here! Learn how to get started, and continue to provide feedback.
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 testing as previews 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.
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.
