Restricting the Collection of Location Information

You can restrict our access to and collection of the location of your Device by disabling Location Services on your Device, if that feature is available on your Device.  Some of the Application Services require access to and collection of the location of your Device to function and if you disable sharing of your Device location in your Device settings, some of the Application Services will not function properly.  You can also restrict our access to and collection of location of your Device by logging out of the Application.

Sharing of Information with “My Family” members

By using the Application, other members of your “My Family”, now or in the future, may have access to your account information, phone number, device information, driving status, and the location of your Device, even when your Device is outside of the United States or Canada.  You can restrict the sharing of your information with you “My Family” members by turning off Location Sharing in the Application Settings menu.

GM may use device tracking technologies that allow us to identify you on your Device in a unique manner, such as use of IP address, to gather information about your activity within the Application Services, such as demographic data, browser type, pages visited, activities conducted on the page, and the day and time of your visit. GM uses this information, sometimes across devices, to measure your activity, remember your preferences, maximize and improve the performance of our products and services, and customize your experience.
