The group says Google parent Alphabet Inc unlawfully collected personal information of iPhone users by bypassing the default privacy settings.

Bloomberg reports that Google plans to challenge the lawsuit and has said there is no merit in the case. The group says Google breached privacy of 5.4 million iPhone users and each of these users stand to get several hundred pounds in damages if they successfully prove the case. Richard Lloyd, a consumer advocate leading the case said the lawsuit is intended to send a strong message to Silicon Valley tech giants that they are willing to fight back in case laws are broken.

The group says Google used an algorithm to trick iPhones into giving away personal data from the Safari browser between 2011 and 2012. Lloyd added that Google's actions were against the law and has affected millions of users. The group adds that affected customers are part of the claim and can opt out if they want. In order to succeed in court, the group will have to show that customers are concerned about Google's use of their personal data.
