Quarterly reports

Q4 2024

31 January 2025: the CMA published Googles progress report on its compliance with the binding commitments accepted by the CMA. The report covers the period from 1 October 2024 to 31 December 2024.

Under the commitments, Google is required to report on the progress of the Privacy Sandbox proposals, its interactions with the CMA and third parties, as well as the approach taken to address concerns raised. We published the full report to inform third parties of developments on the Privacy Sandbox.

We have a role in supervising Google to ensure that the Privacy Sandbox is developed in a way that benefits consumers. As part of this role, we have continued to engage with Google on the design and development of the proposals.

The?ICO?has been closely involved in this process, given that the aim is to ensure that both competition and privacy are protected.

We have also received the Monitoring Trustees assessment of Googles compliance with the relevant provisions of the current commitments (paragraphs 25 to 27, 30 to 31 and 33). The Monitoring Trustee has not informed the CMA of any instances of Google being non-compliant with its obligations under those provisions of the commitments.

As discussions with Google on changes to the commitments are ongoing, the CMA will not publish an update report for this quarter. We expect to provide a further update soon.
