Allow me to draw your attention to this Windows Phone application certification requirement:
Requirement 2.7.2 the privacy policy of your application must inform users about how location data from the location service API is used and disclosed and the controls that users have over the use and sharing of location data. this can be hosted within or directly linked from the application.
Shocould you submit an application that uses location service API and do not provide a privacy policy you will get a friendly response from the certification something like this:
Fail: it appears the application uses location services but does not include a Privacy Policy describing how the application uses the location service API and what control users have over the usage and sharing of information obtained through that usage.

When setting this setting, you must have a privacy statement, I want to explain to the user the purpose of obtaining the location and promise not to disclose the location data to a third party. My privacy statement is:
