Common questions
How do I add my books?
Drop an EPUB or PDF anywhere on your library and it appears on the shelf. On iPhone, iPad, and Mac you can also use the + button, share a file into Bibliotheca from another app, or add a physical book by scanning its barcode.
Where is my library stored?
On your device. Bibliotheca is local-first: you can use it fully without an account, and your books never leave your device unless you turn on syncing. See the privacy policy for the detail.
My books are not appearing on my other device.
Syncing is part of a membership. Check that both devices are signed in to the same account and set to the same sync option in Settings, and that Settings shows the sync status as up to date. Large EPUB and PDF files download on demand the first time you open a book on a new device, so a book can appear on the shelf before its file has arrived.
I paid, but the app still shows the free tier.
Open Settings and use Restore Purchases, then quit and reopen the app. If it still has not appeared, email us with the date of purchase and we will sort it out directly.
How do I cancel a membership?
Memberships bought on iPhone, iPad, or Mac are managed by Apple: open the Settings app, tap your name, then Subscriptions. We cannot cancel or refund an Apple subscription on your behalf, but Apple can.
How do I delete my account?
In the app, open Settings and choose Delete Account. This removes your account and the data synced to it. Books stored only on your device are not affected, and deleting the app removes those.
Something looks broken or a book will not open.
Tell us the book's format and, if you can, send the file — most rendering problems come down to an unusual EPUB and we would like to fix them properly rather than guess.
