Common questions
How do I add a book?
Tap + on the Library tab. You can scan the barcode on the back cover, search by title, author, or ISBN, or enter the details by hand.
The scanner won't open.
Tesoroteca needs camera access to scan barcodes. Turn it on in the iPhone Settings app under Tesoroteca → Camera. The camera image never leaves your phone.
My book wasn't found, or it has no cover.
Some books, especially newer releases, aren't in the book databases yet. Tesoroteca still saves the book with its ISBN. Later, open the book and tap Find a Match to search again.
Can I use it offline?
Yes. Everything works without a connection, including adding a book by its ISBN. Missing details and covers fill in, and your changes sync, once you're back online.
My books aren't showing up on my other iPhone.
Make sure both devices are signed in with the same Apple Account, then open Tesoroteca and go to Settings → Sync Now. The Settings tab shows when your library last synced and any error.
What's the difference between Library and TBR?
Library has two pages: Read holds the books you've finished or set aside, and TBR (Por leer) is your to-be-read pile, with the books you're reading at the top. Swipe between them, and sort or filter either one.
What happens when I sign out?
Signing out removes your library from that device. It stays safe in your account and comes back when you sign in again.
How do I delete my account?
Go to Settings → Delete Account and confirm with Sign in with Apple. Your account and every book in it are permanently deleted from our servers and all your devices. This can't be undone. See the Privacy Policy for details.
