Sharing your data with Google means it can be combined with other Google data about you, significantly expanding the profile Google holds and the ways your data can be used.
Waze continuously collects your precise location data, driving behavior, search queries, and device identifiers, which may be shared with Google and third-party advertising partners. Your driving patterns and location history can be used to build a profile for targeted advertising even when the app is running in the background. You can request access to, correction of, or deletion of your personal data by contacting Waze at waze-support@waze.com or through the in-app settings.
