Windows Phone also tracks users’ location data and sends it to Microsoft

On Monday CNET reported that the mobile operating system of Microsoft also tracks users’ location data and sends it back to the company’s servers. Unlike the Apple’s iPhone and Google’s Android, Windows Phone does not store location details on the device.

Microsoft has said in the Help and how-to subsection under the Windows Phone paragraph that when location services for Windows phones are switched on, the devices transmit a unique ID along with nearby wireless networks, their signal strength, and GPS-extracted location to the company's servers.

iPhone 4 stores locations in an easy-to-read file that can store months, and potentially years, worth of data. Android indexes locations of cellphone towers and Wi-Fi networks the handset has connected to, but limits entries to 200 and 50 respectively.
