Depending on your settings, we may share information such as the ad identifier for your mobile device, or “hashed” versions of your email address or phone number. Hashing is a one-way process that converts your data into a string of letters and numbers, which Uber uses to secure (and avoid sharing) original data values with partners while allowing them to match to your data. We may also share information regarding your usage of Uber’s apps and websites, such as your trip, order and search history, and your current trip information.
