A little care, behind the magic.

Chapter One privacy policy · Updated September 4, 2026

Chapter One is made by Gazzini Ventures for families to create and read personalized storybooks together. A parent or guardian manages creation, optional photos, purchases, sign-in, and sharing.

What stays on your device

Your local library, reading settings, and saved cast are stored on your device. Account credentials use the device’s secure storage. Speech recognition for reading runs on the device; that reading audio is not sent to our generation server. Microphone access can be changed in your device settings.

Making a story

Creating a book sends the story idea, chosen world, and cast details you provide to our server. We use external providers to write the story, produce illustrations, and generate narration. Current provider integrations include Google, OpenAI, Replicate, and ElevenLabs. A provider receives the inputs needed for the requested stage; its own processing and retention terms apply.

Photos are optional. If you add one, it is transmitted to our server and the image provider to create an illustrated character. Our server holds the original photo only as temporary generation data: it is deleted after the character stage, when a job ends, or by a 24-hour cleanup backstop. Original child photos are never saved to our asset storage. Finished book records exclude original photos and appearance descriptions.

The server keeps job status and generated story assets so the app can finish or resume downloading a book. Completed generation jobs and their temporary assets are cleaned up after seven days. Books deliberately uploaded for sharing stay until deleted. Server-stored books and account-linked generation data can be removed through Delete online account. We do not log story prompts, request bodies, photo content, or narration text. Operational logs contain request paths and status, or task identifiers, status, and timing.

Accounts and purchases

Reading the free stories needs no account. To buy book credits, a parent signs in with Apple, Google, or an email address and password. We store the sign-in identifier the provider gives us, your email address when it is shared with us, and a hash of your password; we never ask for a child’s name, email, or age at sign-in. Sign-in links your devices to one account so credits and shared books follow you. Apple processes App Store purchases. RevenueCat manages the purchase customer identity and book-credit balance; we do not receive your full payment-card details. RevenueCat processes verified App Store purchases and adds the associated book credits to your account.

Password-reset emails are sent from chapterone.fun through Amazon Web Services. Apple handles offer-code redemption. We download aggregate sales reports containing offer codes, quantities, countries, currencies, and proceeds to calculate affiliate commissions. These reports do not identify individual buyers. Affiliate code ownership may be linked to the affiliate’s account.

Sharing is a grown-up choice

Sharing a link uploads a finished, scrubbed book and its illustrations and audio. Anyone with that link can read the book, including the names and illustrated characters it contains. Links are unlisted and marked to stay out of search results; they are not password-protected. Share them with people you trust.

Stop sharing turns off the public book link. Previously issued media links may remain accessible until they expire, normally within one hour. We cannot recall files or pictures another person has already saved. Exporting a book file shares a separate copy that you manage yourself.

Your controls

For grown-ups includes sign in and sign out, book backups, sharing controls, and Delete account. Deletion removes the account and its sign-in identifiers, unused credits, associated server books, and generation data across every device signed in to it. Stories and cast photos already saved on your device stay there; you can remove them from your collection and cast. Apple or RevenueCat may retain purchase records under their own obligations. Deletion does not cancel or refund a completed consumable purchase. You can request an eligible purchase refund through Apple.

We do not sell personal information or use advertising trackers. If you contact support, we receive the information you choose to send. Please do not email child photos, passwords, or payment details.
