NaviGator and its developer take your privacy very seriously. Beyond the information Apple provides to developers (which you can opt out of), NaviGator also uses Firebase Services (Firebase's Privacy Policy can be found here – note that NaviGator only uses a small subset of Firebase's many services). These services help to identify crashes and stability issues (Crashlytics and Performance Monitoring) and why they're caused (e.g. a condition that is crashing a lot of devices), which greatly speeds up and eases the ability to fix them. Firebase Analytics is also used to better understand user demographics. NaviGator does not sell or rent your data, and the information collected is solely used to help make the app better. All collected data is tied only to a unique device identifier – it is otherwise completely anonymous.
By using NaviGator, you are additionally subject to the privacy policy of the Regional Transport System.
