The Competition and Markets Authority (CMA) said the commitments were a result of action it launched against the US company in January following concerns that its proposals could restrict competition in digital advertising.

Google had said its new technology - called the Privacy Sandbox - would allow users to receive relevant advertising without being tracked on an individual level.

The company said it had welcomed the opportunity to work with a regulator on its initiative with the aim of reconciling privacy and competition concerns.

"Today we are offering a set of commitments — the result of many hours of discussions with the CMA and more generally with the broader web community — about how we'll design and implement the Privacy Sandbox proposals and treat user data in Google's systems in the years ahead", the company said in a blog post.

It said there would be no data advantage for Google advertising products under its proposals, and its advertising products or own sites would not have preferential treatment.
