Account information, such as your email address and the profile name, avatar, avatar border, and color you choose.

Book club activity, including clubs you create or join, club membership, books added to club shelves, reading progress, chapter notes, excerpts, replies, reactions, and favorite club preference.

Book search information, such as search terms and normalized book details returned by book data providers so Chapters can display and cache book results.

Purchase information if you buy a Library Card or Founder’s Edition, such as the product, store, purchase and expiration dates, and subscription status. This information is linked to your account. Chapters does not receive your full payment card details.

Notification information if you enable notifications, such as your push token, device identifier, platform, and notification preferences, plus the notifications we send you.

Anonymized device and app information used to keep Chapters reliable, such as app version, platform, diagnostics, crash reports, and similar technical data. Analytics and crash reports are not tied to your identity.

We use your information to provide Chapters: authentication, profile display, clubs, shared shelves, reading progress, spoiler-gated chapter notes, replies, reactions, invitations, and account preferences.

We use purchase information to provide, restore, and manage your access to paid features.

We use notification information to send the notifications you’ve enabled, such as activity on notes.

We use anonymized technical and diagnostic information to troubleshoot issues and improve app performance. We use operational security records, such as failed join attempts, to protect the service and prevent abuse.

We do not sell your personal information and we do not use your private notes or reading activity for third-party advertising.

Your profile name, avatar, avatar border, dot color, club membership, reading progress, notes, excerpts, replies, and reactions may be visible to members of the clubs where you participate.

Chapter notes are spoiler-gated: other members should not see the full text of a note until they have reached that chapter, though an excerpt you choose may be shown before then.

Club invitation codes can be used by people who receive them to request access to a public club. Private clubs do not have an active join code.

Chapters uses Supabase for authentication, database, storage, realtime services, and edge functions.

Chapters may use book data providers, such as Hardcover, to return book search results.

Chapters uses RevenueCat to manage purchases and subscriptions, using an identifier linked to your account. Apple, Google, or Stripe processes your payment, depending on where you buy, and handles your payment details under its own privacy policy.

Chapters uses Expo’s push notification service, along with Apple and Google, to deliver notifications. These services receive your push token and the notification’s content.

Chapters may use Sentry or similar diagnostics providers to collect anonymized crash reports and app health information. We take steps to avoid sending personal information or sensitive user-generated content in diagnostics.

If you choose a profile picture or custom book cover, Chapters asks for photo library access so you can select and upload that image. The app does not access your photo library unless you initiate that action.

If you scan a quote from a physical book, Chapters asks for camera access. Scanned images are processed on your device and are not uploaded. The recognized text is only shared if you post it in a note.

Profile photos and custom book covers are stored in the app’s image storage and may be publicly accessible by URL so they can be displayed in the app.

We use reasonable technical measures, including Supabase authentication and row-level access controls, to protect account and club data.

We keep information for as long as needed to provide Chapters, comply with obligations, resolve disputes, and maintain backups or security records. Some content may remain visible to club members until deleted or until your account or data is removed.

You can update your profile photo, avatar border, dot color, theme preference, club participation, book status, reading progress, notes, replies, and reactions through the app where those controls are available.

You can sign out from the You tab. To request account deletion, visit readchapters.app/data-deletion. For data access or correction not available in the app, contact Chapters support at readchapters.app/support.

You can change or turn off notifications in the You tab or in your device settings.

You can manage or cancel a subscription from the You tab or through the store where you bought it.

Chapters is not directed to children under 13, and we do not knowingly collect personal information from children under 13.

We may update this Privacy Policy as Chapters changes. If changes are material, we will provide notice in the app or by another appropriate method.
