Sometimes you send documents out that contain sensitive information you may not want others on your team to have access to. When a document is marked as private other users will get the error message "Could not find document" when they try to open it.
A private document will not appear in any statistics and in contract management.
An admin can always see all user's documents. Even if they are marked as private.
