Organize, Track & Discover Books
When your library turns into a pile
You love books, but your collection has slipped out of your hands. You’re in a used bookstore holding The Night Circus, unsure if you own it so you buy it just in case, only to find another copy waiting at home. Your books are scattered across rooms and boxes, some lent out and never returned, others you know you have but can’t find. You can’t remember what you’ve read, when you read it, or the lines that once stayed with you. Recommendations don’t understand your tastes, so you keep returning to old favorites. And every time you move, you pack hundreds of books with no record of what’s missing or what your collection is worth.
Your books, within reach
Your library becomes something you can reach again. In a bookstore you check your phone and see you already own The Night Circus. No duplicates, no second-guessing. You photograph your shelves once and your collection organizes itself, each book tied to the place it rests so you can actually find it. Lending feels safe because you know who has what. Over time your reading life takes shape. Recommendations finally reflect your taste, and when you finish a book, the next one is waiting. Organizing stops feeling like maintenance and starts feeling like your personal own library - your own oasis.
How Shelfmark™ handles accounts, data, and responsibility
Our apps are designed for private use within families and trusted groups.
Below you can find clear explanations of how accounts work, how content is handled, and how your data is protected.
How this app works and protects you
Accounts & Sharing
Accounts & Access
An account is required to build, organize, and access your personal library in Shelfmark, including your books, notes, and reading history.
Private by Default
Your library is private by default and only visible to you and the people you choose to share it with. Shelfmark is not a public social network and does not display your collection to strangers.
Sharing & Collaboration
You may choose to share parts of your library with others. You control who has access and can update or remove permissions at any time.
Control & Deletion
You can leave shared spaces, remove collaborators, or delete your account at any time. Account deletion is available within the app, and your data will be removed in accordance with our data retention practices, except where required for legal or security purposes.
Content & AI
You Stay in Control
You can add books, notes, and personal entries to your library. AI tools may assist with cataloging, organizing, and generating recommendations, but you decide what is saved.
Your Library, Your Voice
You remain the owner of your content, including your notes, collections, and personal organization.
AI as a Guide
Shelfmark’s AI helps you discover, organize, and reconnect with your reading. It does not publish or share your content without your permission.
Your Data Is Not Used to Train AI
We do not use your private library, notes, or personal content to train generative AI models. Your data stays yours.
A Thoughtful Space
We provide tools to report misuse and maintain a respectful environment for all users.
