Please note that when your location is enabled through settings/charms page, this app does not actually collect or use your current location (neither it stores nor it transmits anywhere).
Instead - the Bing Maps control (provided by Microsoft) may access your location while it is rendering maps.
As such each time this app displays a venue map - Microsoft may collect information about your location to provide and improve its location service. This information is not used to identify or contact you.
Please note that if you disable the location services from settings page then you will not be able to locate yourself in Maps.
