1. Who is responsible and how to contact us
Effective November 12, 2026. Capitu Clubs operates the Capitu app and this website and is responsible for the processing described in this policy. In this policy, ‘we’ means Capitu Clubs.
For privacy questions, requests about your information or concerns about someone’s safety, email hello@capituclubs.com. You can also open a support request in the app. Please do not send passwords, sign-in codes or payment-card details.
2. Local use and account synchronization
You can keep a reading library on your device without creating an account. In local mode, your library records do not use Capitu account synchronization. Removing the app or its local data can remove that library; an operating-system backup may be managed separately by you and Apple.
Local mode does not mean that every feature is offline. Catalog searches, book information and cover requests use network services. The entitlement integration described below can also connect without a signed-in account.
When you sign in, library records and saved companion conversations synchronize with Capitu so they can be available on your connected devices. Social features, clubs and support tickets also use our servers. Signing out or turning off AI does not itself delete records already synchronized.
3. Information we process
The information involved depends on the features you use:
- Account and profile: name, email, username, account identifier, authentication records and optional profile information or images. Sign in with Apple supplies the information you authorize Apple to share, which can include a relay email address.
- Reading activity: books, shelves, wishlist, reviews, ratings, notes, quotations, progress, reading sessions, goals, preferences, achievements and catalog contributions.
- Community activity: follows, invitations and referral attribution, club membership, messages, suggestions, votes, meetings and attendance choices, reports and blocking choices.
- Companion and support: saved AI conversation messages and replies, support requests, replies and information you choose to include.
- Search and technical information: catalog search terms and query caches, request metadata such as IP addresses and server logs used to deliver and protect network services. An optional KOReader connection sends document/progress identifiers and can send its device identifier.
- Entitlement information: the account or anonymous identifier and customer or purchase-history information handled by the RevenueCat integration. The current release has no paid plan to purchase, and Capitu does not collect payment-card numbers.
4. Why we use information
We use this information to provide accounts and synchronization, organize reading records, find books, personalize reading features, enable conversations and clubs, deliver account emails, answer support requests, and prevent abuse or unauthorized access. Reports may include a snapshot of the reported content for review.
Where data-protection law requires a legal basis, processing needed to provide requested account and service features supports our relationship with you; optional permissions and AI choices use your consent where required; service security and support can involve legitimate interests subject to your rights; and some processing may be necessary to meet a legal obligation. We do not treat acceptance of this policy as blanket consent to every use of data.
5. What other readers can see
Your profile settings, shelf visibility, review settings and club membership determine what you share with other readers. Club messages, meeting details and contributions to group activities are visible to the relevant participants. Information you publish publicly can be viewed by other readers; invitations and shared links can reveal the information the feature is designed to share.
Check the audience before posting, and do not include private information about yourself or another person that you do not want that audience to receive. Other people can copy information they see. Changing visibility cannot retrieve copies already made outside the service.
6. Apple Intelligence and saved conversations
Personal AI features are optional and use Apple Intelligence on a supported device in this release. Generating companion replies, book summaries and personal recommendations happens on the device; Capitu does not send those generation requests to an external AI provider in this release. Device and language availability determine whether these features can run.
Generation and storage are separate. If you use an account, saved companion messages and replies can synchronize with Capitu, along with your library. Resolving a suggested book can also request information from the network catalog. Turning off AI stops use of that feature; it does not erase existing conversations. Contact us or use the available deletion controls to request removal.
7. Imports and device permissions
Imports read the library information you select from a file, supported service or Safari extension. Matching books can send titles, authors and ISBNs to Capitu and catalog providers. Imported records then follow the same local-storage, synchronization and visibility rules as other library records.
The temporary import browser is used to sign in to the source service. Capitu does not upload your Amazon password or Skoob sign-in link to its own server as part of that flow. The temporary browsing session is cleared when the import flow ends; the source service remains responsible for its own account and website practices.
- Camera access is used to scan ISBN barcodes. You can type the ISBN instead.
- Photo permissions support saving reading cards; images you choose to submit are handled according to the feature and its visibility.
- Notification permission supports reading and meeting reminders. You can change permissions in your device settings.
- The Safari extension processes supported pages when you use its import features. You control its website access in Safari settings.
8. Service providers and outside services
We use infrastructure and integrations to perform particular service functions. Their involvement depends on the feature and active configuration. Our responsibilities under applicable data-protection law remain when we use a provider.
- Apple supplies App Store distribution, optional Sign in with Apple, device permissions and on-device Apple Intelligence. Apple also applies its own policies to its services.
- Vercel hosts this website. Cloudflare provides network delivery/security infrastructure and storage for contributed catalog images. These services can process connection and request information needed to deliver content.
- Resend delivers account emails when email delivery is configured, processing the recipient and message information needed for delivery.
- RevenueCat handles entitlement/customer information when its integration is configured, including an anonymous identifier or Capitu account ID and available purchase information. Disabled billing does not necessarily disable this integration.
- Book lookups use sources such as Open Library and Inventaire; enabled catalog integrations can also include Google Books, Hardcover, ISBNdb, Amazon, Wikidata and BrasilAPI. They receive lookup information such as search terms, book identifiers and language rather than a request to access your entire Capitu account. External cover-image hosts receive the requests necessary to load their images.
- When you open an external link or import from another service, that service’s own terms and privacy practices apply to your interaction with it.
9. Where processing happens
Capitu’s servers and the infrastructure of service providers can process information in countries other than where you live. Available protections and legal rights can differ between countries. Any international transfer must follow the requirements that apply to that processing. Contact hello@capituclubs.com for information about the providers, locations and safeguards relevant to your request.
10. Website preferences and tracking
This website does not include advertising trackers or audience-analytics scripts. Its help search runs in your browser. Search text and category choices can appear in the page URL, so avoid entering sensitive information and remember that sharing a URL can share that text. Network requests for a page can appear in hosting or security logs.
Your language and appearance choices are saved in your browser to remember your preferences, using the local storage keys capitu-language and capitu-theme. The site does not require advertising cookies. The app does not use an advertising identifier or cross-company advertising tracking in this release. We do not sell your personal information or share it for cross-context behavioral advertising.
11. Retention and deletion
We keep account information while it is needed to provide the service and handle requests, security issues and applicable legal obligations. The appropriate period depends on the kind of record and its purpose; reading records, short-lived authentication tokens, search caches and operational logs do not all have the same lifecycle.
You can request account deletion in Settings → Account → Delete account. Deletion is scheduled 30 days after the request, and the app shows the scheduled date. You can restore the account during that period to cancel deletion. After the period, the scheduled cleanup removes the account and dependent personal records, including the personal library, reviews, notes and saved companion conversations. Leaving a club can transfer administration to another member.
Some shared club messages, posts, content warnings and shared catalog or club records currently remain after account deletion with the account association removed. Their text can still contain information you supplied; removing the association is not a guarantee of anonymity. Contact us to request removal of remaining personal content.
Account cleanup does not mean every backup, operational copy or provider record disappears at the same instant. Retention in those systems depends on their purpose, applicable legal duties and the relevant deletion process. Contact us for details or to exercise a deletion right. We do not promise a fixed backup-expiry period in this policy.
In local mode, use the local-data controls or remove the app to erase its local library. Manage any separate device backups through your operating-system settings. Uninstalling the app does not delete a synchronized account.
12. Your choices and rights
You can change profile and sharing settings, manage permissions, disable optional AI, export available reading records as CSV, and request account deletion. A CSV export is not a complete export of every account record.
Depending on the law that applies, you may request confirmation of processing, access, correction, deletion, portability, information about sharing, restriction or objection to processing, and withdrawal of consent. This can include anonymization or blocking of unnecessary or unlawfully processed information and review of solely automated decisions that affect your interests. You may also contact the competent data-protection authority. Withdrawal does not change the lawfulness of processing already performed.
Send requests to hello@capituclubs.com. We may ask for information reasonably necessary to verify that the request concerns your account and protect it from unauthorized access. We will address requests under the applicable legal requirements and explain any lawful limits on fulfilling them.
13. Security and younger readers
We use access controls, authenticated account requests and other measures intended to protect information. No device or online service can guarantee absolute security. Protect your device and account credentials, and tell us if you suspect unauthorized access.
The service is not designed specifically for children. Check the age rating shown in your App Store region and applicable requirements for a young person’s use. The app includes social features and literature that may discuss mature topics; content warnings and spoiler controls are not parental controls or age verification. If you believe a child supplied personal information without authorization required by law, contact us so we can investigate and address it.
14. Changes to this policy
We may update this policy as the service or its data practices change. The date above identifies the current version. We will provide additional notice or seek consent when required for a material change. Questions about this policy can be sent to hello@capituclubs.com.
