NonFreeDep: The application depends on a non-free application (e.g. Google Maps) - i.e. it requires it to be installed on the device, but does not include it.
NonFreeNet: This application promotes or entirely depends a non-Free network service.
Tracking: The application tracks and reports your activity to somewhere – usually either without your consent, or by default (i.e. you’d have to actively disable it). It’s commonly used for when developers obtain crash logs without the user’s consent, or when an app is useless without some kind of authentication.
