A Windows Phone 7 user in the US has sued Microsoft for collecting and transmitting location data without her consent.

The new lawsuit alleges that Microsoft ignores user requests to turn off the location tracking feature in phones using Windows Phone operating system (OS), according to Reuters.

The lawsuit filed on behalf of Rebecca Cousineau claims that activating the camera application on phones running on Windows Phone 7 OS transmits transmits data including latitude and longitude coordinates of the user’s device without user consent.

The proposed class action, filed in a Seattle federal court, accuses Microsoft intentionally designed camera software to ignore user requests that they not be tracked.

The lawsuit seeks an injunction and other punitive action.

Microsoft has not commented on the matter so far.

Mobile phone location tracking, a tool sought after my marketers, raised privacy concerns in April this year, after two British scientists said that almost all major smartphone OS including Android and Apple iOS collected data without user’s knowledge.

Apple refuted the claim, but soon issued a patch to fix the problem. Microsoft and Google claimed that they collected data with user consent.
