Where should I display the short and long versions?
Place the short notice near the booking action, where customers decide whether to reserve. Put the full wording on a policy page or in the confirmation, with a clear way to request a change.
What is the difference between a 24-hour cutoff and the previous calendar day?
A 24-hour cutoff is measured back from the appointment time. A previous-day rule may use a fixed time such as 17:00. Choose the wording that matches the rule you actually apply.
Should cancellation and rescheduling have different rules?
They can. State whether a deposit carries over to a new appointment, how much notice is required to move a booking and what happens if the new date costs more.
What if several services have different notice periods?
Create a separate version for each materially different rule. A short haircut and a full-day private event may need different lead times to refill the space.
Will the generated policy apply charges or issue refunds?
The output is a text draft. Configure the actual booking deadline, payment collection and refund workflow separately, then test a cancellation as a customer.
Does this produce jurisdiction-specific legal advice?
The draft reflects the choices you enter. Local requirements, consumer rights and the terms of your particular offer can affect what you may publish and apply.
