Chris Hoofnagle, a privacy law professor at UC Berkeley’s Center for Law and Technology, said Google shouldn’t treat users in different countries the same. In the U.S., where there’s no requirement like Europe’s, he said, Google should keep the records only long enough to provide more targeted results and track clicks on ads.
It would be “easier than ever” for Google to sort searches by country and keep only the minimum amount of data required by law, he said.
