Relevant permissions
Permissions based on spaces and users/groups
Default permissions
Read/view permissions
All events are visible for all users.
Write/edit permission
Events can be edited/deleted by the event creator or any Confluence administrator.
Limit read/view permissions
You can limit read/view permissions of an event to specific spaces. Only users with access to these spaces will see the event.
Add write/edit permissions
You can add write permissions to an event. To do so, add users or user groups as editors to the event. These event editors have full write/edit permissions for the this event.
Add anonymous permissions

In order to make events visible to anonymous users, the user profiles must be made public (right-hand checkbox) in addition to the general access (left-hand checkbox) in the administration area under Global Permissions -> Anonymous Access.
Without both ticks, anonymous users cannot see any events.
Safety Guidelines
We strongly recommend the following Confluence configuration settings to avoid potential security risks:
Make sure people are not allowed to register their own accounts, especially without restriction to your domain.
If you allow anonymous access, make sure anonymous users don’t have permission to create or edit anything anywhere (pages, blogposts, comments, attachments etc. in any space).
If you configure your instance differently, you do so at your own risk.
