Access to the calendar is controlled by three permissions, grouped under Calendar on a crew member's permissions screen. They are checked only for the Crew role: a captain can always view, add, edit and delete events, and a viewer can always look at the calendar but never change it.
| Permission | What it allows |
|---|---|
| View | Opens the Calendar entry in the vessel sidebar and the calendar page itself, including event details and attached files. |
| Edit Events | Adds the Add Event button, allows dragging on the grid to start a new event, and enables editing an existing event and its attachments. |
| Delete Events | Shows the bin button on a calendar event's details window and allows the event — and its files — to be deleted. |
The permissions are independent: someone can be given View alone, or View and Edit Events without Delete Events, so that events can be created and corrected but not removed.
The calendar belongs to one vessel, so it is reached from that vessel's sidebar rather than from a company-level screen. The sidebar entry is shown to captains, crew members holding View, and viewers.
Read-only roles never get more than viewing. Even where the calendar permissions are granted, a viewer sees the grid and the event details but no Add Event button, no Edit button and no bin button, and cannot upload or remove attachments.
These permissions govern the calendar page itself. They say nothing about the records reflected onto it: whether you see a document expiry, a task due date or a crew document expiry — and whether its Open link is active — is decided by your permissions in those areas. A crew member with full calendar permissions but no access to tasks still sees no task due dates on the grid.
