Jacob Kohnstamm, chairman of the Dutch data protection authority, added in a statement: "Google spins an invisible web of our personal data, without our consent. And that is forbidden by law.”
The Dutch authorities say they will decide whether to “take enforcement measures” after conducting a hearing.
For its part, Google has always said that it wants to use the data in order to target people more precisely. The company also points out that it isn't collecting any more data than in the past, only using it in new ways.
