Specifically, the ICO found three main areas of concern. First, the group says Google needs to provide more information about how it processes users' personal data. Google also needs to inform users specifically what their personal data is being used for so they fully understand the implications of using Google's services; and lastly it must inform users when retention of personal data might exceed service users' reasonable expectations.
The warning follows similar complaints from the equivalent organization France last month, which put a legal order in place on its recommendations, giving Google three months to respond or face court action. Other European nations running investigations into Google's policy include Spain, Germany, Italy, and the Netherlands.
