Purchases and restoration

Use Restore Purchases in the app with the Apple Account used for the original purchase. Connect to the internet while membership is verified. Restoration restores verified subscription access; it does not synchronize favorites or downloaded files.

Downloads and offline access

Download scenes while online, then play them locally. If membership expires while offline, connect to refresh its verified expiry. Downloaded member files remain on the device but require an active membership to use. Remove scenes in the app to free space.

Billing

Manage or cancel App Store subscriptions through Apple Settings. Apple handles refund requests. Use the Apple links below.
