Collector Pro Monthly and Annual memberships are auto-renewable subscriptions on the App Store. Payment will be charged to your Apple ID account at confirmation of purchase.
Your subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period, and the renewal cost will be identified by Apple.
You can manage or cancel your subscription in iOS Settings > Apple ID > Subscriptions, or open the App Store subscription management page from the membership page within this app. After cancellation, you will continue to have access to benefits until the end of the current paid period.
The actual price is shown on the purchase confirmation screen and in the App Store. Subscription benefits include private library features for NAS/WebDAV/SMB, OPDS, and Calibre, as well as Private WebDAV Sync. The scope of benefits is subject to the purchase page description and the Membership Service Agreement.
If Apple provides a trial or promotional offer, eligibility, pricing, and duration are determined by Apple and displayed in the App Store. Refunds are handled by Apple. Membership benefits will end if a refund is granted or a transaction is revoked.
