What is the Privacy Sandbox

The Privacy Sandbox initiative aims to create technologies that both protect people's privacy online and give companies and developers tools to build thriving digital businesses. Privacy Sandbox features are being implemented for both the Web and Android, to reduce cross-site and cross-app tracking while helping to keep online content and services free for all.
