Ex Libris Pro subscriptions are billed by Apple. To manage, cancel, or restore a subscription, use Restore Purchases in the app's Settings, or manage the subscription in your Apple Account settings (Settings → your name → Subscriptions on your device). Refund requests are handled by Apple at reportaproblem.apple.com.
Your library is stored on your device — use Backup & Transfer in Settings to move it to a new device. Barcode scanning requires camera permission, which you can grant in your device Settings. Book data comes from Open Library and Google Books; if a title is missing or incorrect there, it may appear that way in the app.
You can also contact us through the app's App Store listing. We aim to respond to all support requests promptly.
