Wont leave my phone...

The app, when left unchecked, seems to constantly grow in size taking up more storage space!
When I delete the app to redownload, some data remained on my phone and now it wont let me re-install the app because it left 160MB of its data on my phone (which it doesnt allow me to delete!)! Fix it fb. This is beyond frustrating and seems rather shady...
