Privacy Sandbox for the Web aims to reduce cross-site tracking while helping to
keep online content and services free for all.
Privacy Sandbox also helps to limit other forms of tracking, like
fingerprinting,
by restricting the amount of information sites can access so that your
information stays private, safe, and secure.
The Privacy Sandbox proposals are in various stages of the development process. This timeline reflects when we expect new privacy-preserving APIs and other technologies to be ready in support of key use cases, so that Chrome can responsibly phase out third-party cookies. Information may change and will be updated monthly.
The proposals are being developed in public forums, in collaboration with members of the industry. We also continue to work with the UK's Competition and Markets Authority in line with the commitments we offered for Privacy Sandbox for the web. We encourage participation through the many public feedback channels that inform development of the proposals. Stakeholders can also use this form to share feedback directly with Chrome.
