The announcement of the new policy prompted an investigation by the Article 29 Working Party, a group made up of national privacy regulators. Their initial findings have found that "Google's new policy does not meet the requirements of the European Directive on Data Protection, especially regarding the information provided to data subjects".
European Data protection authorities "are deeply concerned about the combination of personal data cross services", according to Isabelle Falque-Pierrotin of the French Data Protection Authority, which is leading the investigation.
Responding to the allegations, Google said that it had fully engaged with the investigation:
“Over the past month we have offered to meet with the [French data protection authority] on several occasions to answer any questions they might have, and that offer remains open. We believe we’ve found a reasonable balance between the Working Party’s recommendations: to ‘streamline and simplify’ our policies while providing ‘comprehensive information’ to users.
