Why do we need to store Goefence data in android app? -

my question self descriptive,i've read lot how utilize geofence api in android app. follow many tutorials , links so.i'm developing application uses geofencing.but still there's 1 question i'm not clear why need store geofence circle in persistent storage. official developers site says that:

define geofence storage

a geofencing app needs read , write geofence info persistent storage.you shouldn't utilize geofence objects this; instead, utilize storage techniques such databases can store groups of related data.

as understanding locationclient used register geofence , same removing it,also triggers notification based on location not accessing storage trigger notification events.so why need store it?

apart in documentation, there no hard requirement persisting geofences. if you're okay loosing geofences after device reboot or creating fences on fly, you're go without persisting them.
