Privacy Sandbox
An initiative to develop technologies that protect privacy and provide tools to build thriving digital businesses:
- Develop new features to keep your information private.
- Enable publishers and developers to keep online content free.
- Collaborate with the industry to build new internet privacy standards.
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.
