IOS 9 how to get places, even if the application is completed

Question

I understand how to retrieve locations in the background. And I understand that there is a chance to get the location even if it is completed Continuous location updates, even if the application is completed in iOS

But. I have a Moves and Foursquare app. If this application does not even work (I quit all applications and the applications are not running), and then I go to "Privacy" and change the application for these places to disable (Never), I see that the arrow in the status bar has disappeared. But when I turn on location updates (Always), the arrow reappears in the status bar, and the applications are not working at that moment. Thus, these applications begin to receive information about places. How? Even if you do not run MOves for several days, this application shows me the correct route for the past days. How do they get the location information of past days, even the application does not start?
