I'm working on a mobile app in which users can log off themselves manually. However inside our app users can subscribe or unsubscribe for push-notifications. We're discussing internally if users should receive push-notifications in case they log off, even though being subscribed for push-notifications. The logout exists mainly because of IT-security reasons. From a data protection point of view we clarified that sending push notifications are feasible as long as a user is subscribed to it.
Do users expect push notifications to be send after logging off a mobile app? Is there any best practice or research on what mobile users expect from logging off a mobile app in general?
During my research I came across the point of "device sharing", which is an argument for deleting all personal data and not sending personal push notifications after a logout. However I feel this use case might be outdated for mobile apps and might / should be handled a layer above on OS level (comparable to a computer with several personal accounts). Any thoughts are appreciated!
