Yes, you can control project access through user roles and sharing settings in Densy.
In Account Settings, you assign roles to team members. This allows you to grant access only to specific projects they are working on. In that case, they will only see the projects they are assigned to.
When sharing a project with a client, you can also define exactly what information the client can see. Additionally, within each project you can decide whether individual rooms are visible to the client or not.
If you export a room or project to PDF or XLSX, you can also choose which information should be included in the exported file and which should remain hidden.
