There has been a lot of confusion about Google’s Privacy Sandbox lately, with some reports saying that the project is dead. The truth is more complicated. Google has officially given up on its long-term plan to eliminate third-party cookies in its Chrome browser, but the broader Privacy Sandbox project is still moving forward. This is a big change in how Google thinks about web privacy. Instead of forcing people to change their technology, they are now focusing on giving users more choices.
The decision, made public in April 2025, came after almost five years of delays and extensive review. Google was caught between industry viewpoints, pressure from regulators such as the UK’s Competition and Markets Authority (CMA), and technical problems with the replacements it proposed. The company ultimately chose to keep things the way they are. Chrome’s current Privacy and Security Settings still let users control third-party cookie settings. They don’t have to get a new prompt or stop using the old one.
The Current Status of the Privacy Sandbox
So, what does this mean for the different technologies developed under the “Privacy Sandbox” name? The project is still going on. Google says in its most recent messages that it is “evaluating the role the Privacy Sandbox APIs can play going forward” because of the new strategy.
The Topics API (for interest-based advertising), the Protected Audience API (for remarketing), and the Attribution Reporting API (for campaign measurement) are still working. Still, their future development plans are under review. The advertising industry has provided feedback that these APIs have problems, including being too complicated, costing too much to run, and not performing as well as traditional third-party cookies.
Google has heard this feedback and is thinking about what to do next. The company is also investing in other privacy-protecting technologies for Chrome, such as IP Protection, which is set to launch in Incognito mode in the third quarter of 2025. Several factors led Google to change its mind about deprecating cookies. Regulators were worried that eliminating third-party cookies while pushing Google’s Privacy Sandbox alternatives could make the company even more powerful in digital advertising.
At the same time, the replacement APIs had technical problems. They didn’t get much use in the advertising industry, which questioned their effectiveness and called them “apathetic” because the timelines kept changing. Early tests showed that removing third-party cookies without strong replacements could have led to a significant drop in ad revenue for publishers using Google’s platforms, and possibly even for Google itself. Due to these problems in the industry, with the law, and with technology, the best way to move forward was to switch to a user-choice model.
In conclusion, it is inaccurate to assert that the Privacy Sandbox is defunct. With third-party cookies still available in Chrome for the foreseeable future, the project is in transition. The focus has changed from a quick change to a slow progression. Google is still working on privacy technologies while engaging with the ecosystem to determine its final role.
