Mobile Device Data. When users download, install and use the Applications on their mobile phone or other wireless telecommunications device, Fitlog automatically gathers information, including without limitation, carrier providers, a unique device identifier, geo-location information (if allowed by the user), the types of mobile devices accessing the Application, and the types of operating systems accessing the Applications (collectively, “Mobile Device Data”). A unique device identifier is a string of alphanumeric characters (similar to a serial number) used to uniquely identify and distinguish each mobile phone or other wireless communications device. Location services can be enabled or disabled at anytime, through the mobile device settings. Fitlog uses Mobile Device Data to understand usage patterns and to improve the Applications. For additional information on Fitlog’s uses of Mobile Device Data, see the section concerning Information Use and Disclosure Practices/Traffic Data and Information Gathered Using Cookies, Web Beacons, and Mobile Device Data, below.
