Background data continues when app is closed.

I use xiialive when I work out, which is about 60 minutes, twice a week, then exit app. At some point in the last week it's gone hay wire. It says I've used almost 60 gigs since June 3rd (5 days). The app does not so up on m "open apps" (long press home button) list or on the running apps list in the system settings. It seems the background data is running no matter what. I have a widget on my home screen. Also, a shortcut to the app on my lock screen. But that's it.

I'm on a rooted droid razr maxx. Cm10.1 Jelly bean 4.2.

Help.
