Cancellation Policy Helper
Cancellation Policy Helper analyses the cancellation policy details from the booking page and provides a clear summary of the refund status (e.g., refundable, partial refund, or non-refundable). It automatically extracts the cancellation policy text from the booking details, calculates the refund type based on the terms, and displays the result directly on the page for quick reference. This extension does not collect, store, or share any data. It simply reads the visible content of the booking page to help you understand the cancellation terms at a glance.
