May I have acces to the app but not the data base?
For example, I share the app and the data base to another Google Drive account, but I need to keep acces to the app in order to make updates and upgrades.
It’s worth noting that refusing to share the data source may not be the privacy win one expects. The developer of the app has access to all data available to the app even if they don’t have direct access to the data source directly.
