Google releases Privacy Sandbox timeline for Chrome
Last month, Google announced that it would delay Chrome’s plan to phase out support for third-party cookies. As part of this, the company provided more details on Privacy Sandbox and today released a rollout schedule.
As promised, the company now has a detailed schedule. Google originally planned to phase out third-party cookies within two years of its announcement in 2020. This is now expected to take place over a three-month period, starting in mid-2023 and ending in late 2023.
Google divides the Privacy Sandbox timeline into four components, with the relevant APIs listed below:
Fight web spam and fraud
Show relevant content and ads
Measure digital ads
Strengthen confidentiality boundaries between sites
Most are currently in the “Discussion” phase, with the exception of the fight against spam / fraud. The next steps are âTestâ and âReady for Adoption,â with Google tagging when original testing (OT) for individual APIs has started in the browser.
Google wants to put APIs in these four areas in place before the transition period and will not begin large-scale deployment until these technologies are “ready for large-scale adoption.” If all goes according to plan, Stage 1 of the transition will begin in the fourth quarter of 2022 and continue through the second quarter of next year. Meanwhile, Google will be monitoring adoption as publishers and the advertising industry migrate. The phasing out of third-party cookies in Chrome will take place during Stage 2 in the third quarter of 2023.
The Privacy Sandbox is also intended to deal with covert tracking techniques, but this does not fall into the four categories. SameSite cookies, User-Agent Client Hints API, and HTTP cache partitioning have all been launched at scale. Wide-scale DNS-over-HTTPS availability is expected (at the earliest) for the second half of this year, while the second half of 2022 will begin to see WebID API, user agent reduction, Gnatcatcher, and cookies. related to the origin. Finally, a Privacy Budget targets 2023.
The Privacy Sandbox timeline will be updated monthly by Google, while there is also an FAQ at the bottom of this page. Meanwhile, Chrome 92 is deploying a FLoC setting to the existing Privacy Sandbox preference page.
