Two Michigan women have filed a $50 million lawsuit against Google over how the company deals with location data on its Android phones, the Detroit News reported Thursday.

In the lawsuit, filed Wednesday in the U.S. District Court in Detroit, the women said that they did not approve of allowing location services on their phones. Their lawyer said that Google’s practices puts “users at serious risk of privacy invasions, including stalking.”

A Google spokesman declined to comment on the lawsuit. The company has said previously that it collects location data from consumers who have opted in to its services and that the data can’t be traced to an individual user.

Last week, a report from two researchers revealed that a file on the iPhone and 3G iPad appeared to track a user’s location. Apple has since said that the file is not a tracking file but a small part of a larger database that iPhones use for location-based services.

On Monday, two Apple customers filed a lawsuit federal court in Tampa, Fla., seeking to ban Apple from collecting location data.

Google and Apple officials have agreed to testify at a Senate hearing on mobile privacy next month.
