Manage or cancel the subscription in Apple Account settings. Lifetime Full Access: NT$599 in Taiwan or US$19.99 in the United States, charged once with no time limit. Apple-localized prices are shown before purchase. The 3-day free trial applies only to eligible annual subscriptions, not the one-time purchase.
