Hello! 
Hi, is it possible for a users data to be hidden so that other users within the same group can’t see or edit the data? The information captured will only be seen by committee members
Hi,
If a project is private, users with a COLLECTOR role have basic access, allowing them to view and upload only their own data via the mobile client or web. This means COLLECTOR A cannot access entries uploaded by COLLECTOR B, and vice versa.
