Go to Settings → Restore Purchases in the app. Make sure you're signed in to the Apple ID you used to purchase. If you used Family Sharing, the family organizer's Apple ID must be active.

Subscriptions are managed by Apple, not by us: open Settings on your iPhone → tap your name → Subscriptions → Spine → Cancel. Cancel at least 24 hours before your renewal date to avoid the next charge. If you bought Spine+ Forever, there's nothing to cancel — it's a one-time purchase.

Refunds are handled by Apple. Go to reportaproblem.apple.com, find the purchase, and request a refund. Apple's refund policy applies. We don't see your payment information and can't refund directly.

Try the ISBN from the back cover or the copyright page — it's more precise than a title search. Covers come from Open Library and Google Books, and older printings or special editions are sometimes missing; for those, tap “Photograph the cover” and use your own photo.

Wipe the camera lens, add more light, and hold the phone about 15 cm from the barcode. If the book predates barcodes (pre-1980s, roughly), search by title or add the cover as a photo instead.

Uninstall the app to delete all on-device data — your library lives on your phone. Email us at help@getspine.app to delete the anonymous purchase-verification account.

No. We don't share data with advertisers, analytics companies, or third parties beyond the minimum needed for purchase verification (RevenueCat) and crash diagnostics. Book searches go to Open Library and Google Books and contain only the search text or ISBN. See our Privacy Policy.
