We use three things already built into your phone to understand your driving and determine your driving score. Your phone’s GPS shows your location and your speed. The accelerometer and gyroscope show how you hit the gas, the brakes, and go around corners. This data together tells us how much and how well you're driving, so we can translate it into estimated carbon emissions data. We also may use the driving data to send targeted marketing to certain drivers about HiRoad auto insurance. Other data is collected by the app that does not impact your driving score. For more detail on the data we collect and how we use it, please see our Privacy Policy on hiroad.com.
