**Developer response:** Hello! You can choose whether to subscribe to membership based on your own needs after a 3-day free trial. When you authorized the trial, you were informed of the expiration date of the free trial, which is not mandatory consumption. To avoid being charged, please make sure to cancel one day before the free trial ends. You can cancel at any time in "Settings">"Apple ID">"Subscription". If the subscription is not cancelled after this date, the system will automatically deduct the fee.
