Summary

The Competition and Markets Authority (CMA) is consulting on a proposal to release the Commitments previously accepted by the CMA from Google in relation to Google’s Privacy Sandbox.

This consultation is being held on another website.

This consultation closes at
11:55pm on 4 July 2025

Consultation description

The CMA had competition concerns regarding Google’s Privacy Sandbox proposals and previously accepted Commitments offered by Google to address these. Google has since announced that it no longer plans to block third-party cookies in general browsing in Chrome, or prompt users to decide if they want to do this.

The CMA now believes the Commitments are no longer necessary and so is consulting before taking a decision on whether to release them.

All guidance documents included in the scope of this consultation can be found on the separate consultation page.
