However, the Information Commissioner's Office (ICO) told Out-Law.com that a regulator in France is currently assessing whether the changes comply with EU law on behalf of it and the other data protection authorities in the trading bloc.
“The impact of Google’s new policy cannot be understated, but the public are in the dark about what the changes actually mean," Nick Pickles, BBW director, said in a statement.
"Companies should not be allowed to bury in legal jargon and vague statements how they may monitor what we do online, where we use our phones and even listen to what we say in calls. This change isn’t about Google collecting more data, it’s about letting the company combine what’s in your emails with the videos you watch and the things you search for," Pickles said.
"If people don’t understand what is happening to their personal information, how can they make an informed choice about using a service? Google is putting advertiser’s interests before user privacy and should not be rushing ahead before the public understand what the changes will mean,” he said
However, in response Google's global privacy lawyer Peter Fleischer defended the changes and said they would result in a simpler and easier to understand explanation of how it uses user data. He also said it would enable the company to offer more personalised services to those individuals.
"Most of our privacy policies have traditionally allowed us to combine information gathered in connection with one service with information from other services when users are signed into their Google Accounts. By combining information within a user's account we can improve their experience across Google ... However, our privacy policies have restricted our ability to combine information within an account for two services: Web History, which is search history for signed-in users, and YouTube, the video-sharing service we acquired in 2007," Fleischer said.
Fleischer also suggested at that stage that Google did not intend to postpone the introduction of its new policy on 1 March.
"As you will know, we had extensively pre-briefed data protection authorities across the EU prior to the launch of our notification to users on 24 January 2012. At no stage did any EU regulator suggest that any sort of pause would be appropriate," he said. "Since we finished these extensive briefings, we have notified 350 million Google account holders, as well as providing highly visible notices to all our non-authenticated users."
In a statement an ICO spokesperson told Out-Law.com: “Any organisation that processes peoples’ personal data must be open and upfront about how this information will be used and for what purpose".
"It is nevertheless important that people read the information organisations provide them with before agreeing to any changes related to the processing of their personal information,” the spokesperson said.
