Book Dragon Terms of Use
Nobody opens a book inventory app hoping the evening ends in legal terms, so this page is going to do the useful thing and explain the rules in language meant to be read by a person. Book Dragon is developed and provided by Brandon Yaniz under the Archive Nine name, and these terms cover the parts of using Book Dragon that are specific to the app, including what the app is meant to do, what it cannot promise, how outside book-information services fit into the picture, what happens when you share a collection, and what we mean when we say Free Forever.
The license for Book Dragon itself is governed by Apple's Standard Licensed Application End User License Agreement unless a different license is expressly provided with the app. If something on this page conflicts with Apple's applicable license, or with rights you have under the law where you live, those controlling terms and rights take precedence.
Book Dragon is a tool, not a promise that memory has been defeated
Book Dragon is built to help you keep track of books, editions, copies, collections, and related information. You decide what goes into your collection, what gets changed, what gets removed, and what gets shared. The app can make it much easier to answer questions like whether you already own a title, whether the copy at home is hardcover or paperback, or whether somebody else in the family already bought the book you are holding, but it is still software, and software has its own ways of being inconvenient.
Information can be incomplete, duplicated, outdated, incorrect, or lost because of software errors, device failures, synchronization problems, changes to Apple services, failures in outside book-information services, or other circumstances Archive Nine does not control. If a particular record is important enough that losing it would become a real problem, keep whatever additional backup or documentation makes sense to you. Book Dragon is supposed to reduce uncertainty around your library. It cannot eliminate every possible way technology can misbehave.
Your collection does not live on an Archive Nine server
Book Dragon does not require an Archive Nine account, and Archive Nine does not operate a central database that stores your collection. Your library stays within Apple's ecosystem, and Apple's own systems handle the storage and sharing Book Dragon depends on. That means your ability to store, synchronize, recover, or share information may also depend on your Apple account, your devices, your settings, network availability, and Apple services that Archive Nine does not control.
This architecture is intentional. It keeps Book Dragon simpler, keeps your collection closer to you, and avoids building another account system whose main purpose would be remembering information you already own. The Book Dragon Privacy page explains this in more detail, including what information may be exchanged with outside services when the app looks up book details.
Shared collections are genuinely shared
Books move around in families even when nobody planned for them to. A copy that started in one room spends six months in another, somebody borrows a book without formally declaring it borrowed, and eventually the household library becomes a little more collective than anyone intended. Book Dragon supports shared collections so the app can reflect that reality. When you choose to share a collection, information in that collection can become visible to the people you share it with, and changes made through shared access can affect the shared collection.
Only share with people you intend to give that access to. Archive Nine does not control the people you invite, their Apple accounts, their devices, or what they may learn from information you choose to share.
Some book information comes from somewhere else
Typing every title, author, ISBN, publisher, cover, and edition detail by hand would get old very quickly, so Book Dragon can use outside services to look up publicly available information about books. Those services are not operated by Archive Nine, and their information is not guaranteed to be complete or correct. A title may be wrong, a cover may belong to another edition, an ISBN may have incomplete metadata, a publisher field may be missing, or a service may stop responding, change what it provides, change its rules, or disappear entirely.
Book Dragon may allow you to correct or replace information in your own collection, but Archive Nine does not guarantee the accuracy of information supplied by an outside source. The Book Data Sources page identifies the services Book Dragon uses and includes any acknowledgments or attribution they require.
Free Forever means what it sounds like, with one important limit
Book Dragon was designed around a simple promise: the core app should remain free. There is no subscription required to use Book Dragon's core library-management functionality, no paid tier required to unlock your collection, no paid collection-size limit, and no required in-app purchase hiding the useful version of the app somewhere behind a button.
Archive Nine may eventually earn money around Book Dragon through optional services, such as affiliate links to places where books can be purchased. If you decide you want another edition, the next book in a series, or something on a wishlist, we may someday help connect you with somewhere to buy it and receive a commission if you choose to make that purchase. That purchase remains optional, and your library does not become less useful because you never make one.
Free Forever is a pricing commitment. It is not a promise that Book Dragon, every individual feature, every outside service, or compatibility with every future Apple device or operating system will exist forever. Software changes, platforms change, outside services change, and sometimes features have to be modified, replaced, or removed. If Book Dragon continues to be offered, the intention is that its core library-management functionality remains free rather than slowly becoming a subscription after you have spent years building your collection inside it.
Book Dragon will change
Book Dragon is not finished simply because a version number reaches 1.0. Features may be added, changed, reorganized, replaced, or removed as the app develops, as Apple changes its platforms, or as outside services change around us. We will try to make those changes without creating unnecessary disruption, especially when existing collections are involved, but we cannot promise that every feature, integration, interface, or outside service will remain exactly as it is today.
When a change is substantial enough to affect how people use Book Dragon, we will try to document it in the release notes.
Use the app lawfully and do not make things weird
Book Dragon is meant for normal personal and household library management and for other lawful uses permitted by Apple's applicable license. Do not use Book Dragon or its connections to outside services to violate applicable law, infringe intellectual property rights, interfere with another person's systems or information, abuse an outside data service, or attempt to get around technical restrictions imposed by Book Dragon, Apple, or a third-party provider.
Nothing in these terms gives you ownership of Book Dragon, its source code, Archive Nine branding, or third-party content that appears through the app.
Outside services have their own rules
Apple services, book-information providers, retailers, websites, and other outside services used or linked through Book Dragon may have their own terms, privacy practices, restrictions, and availability. Archive Nine does not control those services. They may change, become unavailable, or impose their own requirements without asking us first, and your use of those services may also be governed by their own agreements.
Book Dragon is built to use those services where they are useful, but they remain somebody else's systems.
We want it to work, but we cannot promise perfection
The entire point of Book Dragon is that it should be useful enough to trust with the boring details of your library, so we take reliability seriously. That does not mean we can promise that the app will always be uninterrupted, error-free, compatible with every device, or able to recover every piece of information after every possible failure. Book Dragon is provided subject to Apple's Standard EULA, including its warranty and liability provisions, and to any rights that cannot legally be excluded where you live.
Nothing on this page is intended to take away consumer rights that applicable law says cannot be waived.
These terms may change too
As Book Dragon changes, this page may need to change with it. We may update these terms when the app, the services around it, applicable law, or the way Archive Nine operates changes. When we make a meaningful revision, we will update the effective date at the top of the page. Continued use of Book Dragon remains subject to Apple's applicable license and any legal rights that apply to you.
