Set the Cancellation Deadline

We use the online booking system, which allows guests to cancel their bookings by email. How can I configure the cancellation deadline?
How can we configure the system so that guests cannot cancel free of charge the day before arrival? We offer free cancellation up to 5 days before arrival.
Go to the booking settings:

https://w40.cloud-rooms.com/en/settings/bookings

In the Bookings section, under Cancellation Deadline, enter the desired number of days before arrival up to which a booking can be cancelled.

Once the cancellation deadline has passed, guests will see a message stating that the cancellation period has expired and that cancellation is no longer possible when they click the Cancel link in their email.
