Q4 2022: Update from CMA & Google on Privacy Sandbox

Posted on Wednesday 01 February 2023 | IAB UK

The Competition & Markets Authority (CMA) has shared Google’s latest quarterly report, updating on its compliance with binding commitments made in relation to Privacy Sandbox


Google’s report provides a progress update of the Privacy Sandbox proposals, timing expectations, Google’s interactions with the CMA and third parties, including on the testing of proposals. It also sets out the approach Google has taken to address any concerns raised by the CMA or other third parties.

In addition, the CMA has published its latest update report on the implementation of Google’s commitments, which aims to explain the progress made to date and highlight areas of focus where potential concerns have been raised - including through feedback from wider industry - and how they have been addressed.

A key point to note is that the CMA is continuing to encourage the industry to engage with Privacy Sandbox via testing and provide feedback: “We are continuing to encourage those who plan to eventually adopt and use the Privacy Sandbox technologies to engage early with any testing they have the capability to carry out. 

“We also encourage market participants who have concerns about the design and implementation of the Privacy Sandbox to continue providing feedback to us. We would welcome views from members of the online advertising ecosystem on this report, as well as on any other relevant publications (e.g. Google’s own quarterly reports).” 

It adds: “We would encourage participants to raise substantive concerns through existing channels including W3C. Google is required under the Commitments to respond to reasonable views and suggestions, as summarised in Google’s quarterly report which is published alongside this document.”
