U.S. Congressional Rep. Ed Markey (D-Mass.) has sent a formal letter to Google’s CEO Larry Page following the company’s announced changes to their privacy policy. The letter is signed by eight lawmakers, all but one of which is a member of the House Energy and Commerce Committee.

“We believe that consumers should have the ability to opt out of data collection when they are not comfortable with a company’s terms of service and that the ability to exercise that choice should be simple and straightforward,” wrote the lawmakers.

Google has until February 16 to respond to questions put forth by Congress about how it will use the information it collects, who has access to it, whether it will be sold, how long the company will keep the data, whether there are specific provisions to protect children and teens, and how Android users will be affected.
