If the Change Story Privacy field is included within the survey used to create a story, colleagues can use it to change the story’s privacy level while they are creating or editing the story.
You can prevent colleagues (i.e. Project Reporters) from changing a story’s privacy level whilst still allowing Project Managers and Organisation Admins to change it a story’s privacy when they need to.
You must be a Project Manager or Organisation Admin to do this.
Steps
Go to the Project Preferences page of the project that the stories are created within
Scroll down to the Prevent project reporters from changing a story’s privacy section
Tick that box
Scroll to the bottom and press Save
