App Store purchases, subscriptions, free trials, renewals, cancellations and refunds are managed by Apple under the App Store terms shown at purchase.
A paid plan is attached to the Wedding Jukebox account used at purchase or restore. Signed-in planning devices are unlimited, but commercial live-event capacity is limited by plan: Plus supports one, Premium five and Pro fifteen simultaneous live events and current published events. Each live event can be run from one device at a time, and a device can run one event.
If a subscription ends or is downgraded, existing event data is preserved. New live events and publication beyond the active allowance may be blocked, and excess current events may become read-only until the owner chooses which events remain active.
Deleting a Wedding Jukebox account does not cancel an App Store subscription. The owner must cancel billing separately through Apple Subscriptions.
