FastTrack and its developer take your privacy very seriously. Beyond the information Apple provides to developers (which you can opt out of), FastTrack also uses Firebase Services (Firebase's Privacy Policy can be found here – note that FastTrack 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. FastTrack 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.
When signing into FastTrack, it automatically accesses your school's learning management system. Beyond this, FastTrack never performs any actions without you clearly requesting it to (such as by tapping a class or assignment).
Planner notifications are handled entirely by your device – no data related to a planner item is ever uploaded to any server. When you delete or mark a task as complete, the notification is canceled locally.
By using FastTrack, you may be additionally subject to the privacy policy of your school's learning management system.
