EPIC reports: “Google will cut the period that it retains user data from a maximum of 24 months to a maximum of 18 months, the company said in a letter (pdf) to the Article 29 Data Protection Working Party. Last month, the Working Party began to investigate (pdf) Google’s privacy practices and asked whether the company has “fulfilled all the necessary requirements” to abide by EU privacy rules. In its letter, Google did not adequately explain why it needed to retain user data for 18 or 24 months, except to vaguely say that the data would help Google build new services, possibly help prevent fraud and abuse, and that the U.S. and EU member states might impose a 24-month retention requirement.”
