Simply put, NextStop itself does not store or transmit any personally identifiable information.
We use Google Firebase to track installs, report on usage (launches, screens viewed, etc.) and crashes. The specific services we use are "Google Analytics for Firebase" and "Firebase Crashlytics". We also use Google AdMob for Ads. We refer you to the Google Privacy Policies for specifics on their services.
