These are the terms under which Chapbook is made available. By downloading or using the app you accept them. They are written to be readable; they are not less binding for being plain.
What Chapbook is
Chapbook is a native iOS reading app published by Solocosmo Studios. It bundles thirty-one nursery rhymes, fairy tales, myths, and storybook classics — none of them the Brothers Grimm, whose tales live in the companion app, Hausmärchen — in a clear modern reading text, with gentle Junior editions for younger readers and a parent-locked Children's Mode. The illustrations are by Jessica von Braun and Jasmine Becket-Griffith. The corpus is finite and self-contained. The app does not stream, fetch, or update content over the network.
Personal, non-commercial use
We grant you a personal, non-exclusive, non-transferable, revocable license to use the app on iOS devices you own or control, for your private enjoyment and for reading aloud in non-commercial settings (your home, a classroom, a library hour). You may not redistribute the app, the bundled tale texts, the Junior editions, or any portion of the illustration set as a separate product. You may not extract, scrape, mirror, or sell the contents.
The bundled texts and images

Billing
The app is a free download. The optional "Studio Support Edition" unlock opens the complete library — every tale (the free edition opens about half of them), the full Children's Mode Junior library, and the complete gallery with every plate and the artist biographies. It is a one-time, non-consumable In-App Purchase for $9.99 USD (or its App Store local equivalent). There is no subscription. The purchase is processed entirely by Apple. We do not see your payment details.
The Restore Purchases option in Settings re-reads your StoreKit entitlement and unlocks the same content on any device signed into the same Apple ID. Refunds are handled by Apple under its standard policy.
No account, no server
There is no Chapbook account. There is no Chapbook server. Your favorites, last-read position, parent PIN hash, and unlock entitlement live on the device. We have nothing to lose, breach, sell, or hand over because we hold nothing.
Children's Mode and parental responsibility
Children's Mode is a feature provided in good faith for parents and guardians who want to share the gentler tales with a child unattended. It is parent-locked behind a four-digit PIN with an escalating cooldown after three wrong tries. We make no guarantee that any technical filter is perfect; you remain the responsible adult. The Junior editions are written to remove graphic, on-page violence — but they do not remove sorrow or danger. These are old tales: some end sadly, and a bloodless, sung, or off-page death may remain where it belongs to the tale.
Provided as-is
Chapbook is provided on an as-is basis, without warranty of any kind, express or implied — including the implied warranties of merchantability, fitness for a particular purpose, and non-infringement. To the maximum extent permitted by law, Solocosmo Studios and its principals will not be liable for incidental, consequential, special, indirect, exemplary, or punitive damages arising out of or relating to the app, the bundled texts, or these terms.
Some jurisdictions do not allow the disclaimer of certain warranties; in those places this limitation applies only to the extent permitted.
Termination
You may stop using Chapbook at any time by deleting it from your device. The personal-use license granted by these terms ends when you do. We may end the license if you redistribute the app, mirror its contents, or violate Apple's terms of service in a way that affects the app.
Governing law
These terms are governed by the laws of the United States and the State of New York, without regard to conflict-of-laws principles. Any dispute that cannot be resolved by writing to us must be brought in the state or federal courts located in the State of New York.
If the terms change
If we update these terms, the new version will appear at this URL with a new "Last updated" date. Substantive changes will be summarized in the App Store release notes for the build that introduces them. Continued use of the app after a change indicates acceptance of the revised terms.
