The app automatically cancels 'high-risk' orders, send a cancellation confirmation to the customer (optional), restocks the inventory, and refunds/voids the customer's payment (if any). While Shopify automatically flags high-risk orders for you, it doesn't cancel them - you still have to go through your list of orders manually. Whenever you receive a new order, we check it based on Shopify's fraud analysis - if it's a high risk-order, we automatically cancel/refund, preventing any chargebacks.
