+    "Unlimited access" means the app can access the device location even when it's not being used
+    (on background), while "limited" means the app can only access the device location when the user
+    is using it (foreground only).
+
+    Please note that the distinction between singular and plural of this sentence only depends on
+    the quantity of "background_location_app_count" ("has" vs "have"). The quantity of
+    "total_location_app_count" is almost always greater than 1, so "apps" is always in plural form.
