Not to upstage the illustrious Early the Pearly, who is correct, I would say the more nuanced answer is that yes, apps *kinda* do have permissions when not in use.

I say this because apps can be "woken up" at almost any time and the user does not necessarily know when an app is running or not. Oftentimes also, apps will appear to be running when they are not, and the OS doesn't really show this too well to the user.

So while it's true that apps dont really have permissions while not running, they have a dozen or more ways to be "woken up" and be running silently in the background. Also, it's important to note that a lot of apps are held in a sort of "stand-by" mode where they aren't really using memory or CPU, but they are listening for events or have "background-timers" running.

One good thing though: when you install an app it cannot wake itself up and has no permissions until it is run for the first time.
