applock using mobile data in the background

[Dhenry2001]

I am on a small data plan and when i got a notification saying i was almost at my limit i noticed that applock was using far more data than any other app, about 200mb in 10 days.

Please note that this is background data usage, i have switched off the use background data option so that it shouldnt use it

Please say why this is as it is a very useful app and i dont want to have to uninstall it.
