1. Do you have any privacy settings?
Yes, we have two different privacy settings. You can control the overall privacy settings from the settings panel and also control privacy based on each project.
2. Can I assign a task privately to a user?
Yes, you can mark a task as private while creating. Only the person(s) assigned to the task will be able to see that.
3. Can I make the projects public?
No, only the people assigned to a project can see that. And obviously the administrator and the people who have permission to create and manage projects can see too. But the people who are not assigned to a project can not see them.
