The Competition and Markets Authority's (CMA) purpose is to help people, businesses and the UK economy by promoting competition and tackling unfair behaviour.


About this consultation

The CMA consulted on a proposal to release the Commitments previously offered by Google in relation to its Privacy Sandbox proposals.

We originally accepted the Commitments in the context of our investigation concerning Google’s suspected abuse of a dominant position in the market for the supply of web browsers.

The CMA’s concerns were about Google’s proposals to replace third-party cookies and other functionalities in Chrome with its proposed ‘Privacy Sandbox’ tools.

Since the CMA Decision to accept Commitments, Google has announced that it no longer plans to restrict third party cookies in Chrome, or to prompt users to decide if they want to do this.


This consultation is now closed

This consultation closed at 23:55 on 4 July 2025.


Detail of outcome

The CMA has carefully considered the responses to the consultation and it remains of the view that it has reasonable grounds for believing that its competition concerns no longer arise and that it is appropriate to release the Commitments.

Therefore, the CMA has decided to release the Privacy Sandbox Commitments.
