The Privacy Sandbox Timeline for the Web
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. Last Update: January 2023
The technologies and their prototypes are discussed in forums such as GitHub or W3C groups. Some limited testing of solutions might happen at this stage to facilitate discussions.
The technologies for the use case are available for testing via Chrome origin trials or other pre-launch methods. Changes may be made based on testing results and ecosystem feedback.
The technologies for the use case are launched and available for 100% of Chrome traffic. Chrome expects refinements and optimizations as more companies test and use the APIs over time.
Chrome will phase out support for third-party cookies over a two-month period.
