Privacy policy

Effective November 14, 2026. Bookibis is a personal home-library app provided by Pars Kunt, Muğla, Türkiye. Contact the controller using the support email below.

On your device

Your library is stored on your device: your books and editions, shelves and rooms, collections, wishlist, reading status and dates, ratings, notes, purchase details and lending records. Search runs on the device. The photos you take and the cover images prepared from them are kept in the app’s own storage. Browsing your library, adding books by hand and checking whether you own a book all work offline and without an account. Device backups follow your own iCloud or system settings.

Optional accounts and cloud backup

An account is optional. If you sign in with email, your address is used to send a sign-in code. If you sign in with Apple or Google, we receive the identity details those services share with us, such as your email address and, from Apple, your name if you choose to share it. Accounts and backups are hosted by Supabase. When you are signed in, your library is backed up and kept in sync across your devices, including notes, collections, locations, wishlist, reading and purchase details and lending names and dates. Only record other people’s details, such as a borrower’s name, when you are entitled to. Cover images prepared from your photos are backed up; the original photos you take are not. Your backup can only be accessed by your account.

Where data is processed

Cloud data is stored with Supabase in Amazon Web Services’ Tokyo region (ap-northeast-1), Japan. Anthropic, Apple, Google and RevenueCat may process requests in other countries under their own terms. The app uses your device’s language, region and currency settings on the phone for formatting and defaults and does not upload them as a profile. App Store services process your storefront country and currency. Any online request reveals your IP address and ordinary network information to the service that receives it.

AI photo reading

Reading a book from photos is optional. It needs an account and an internet connection, and the app asks for your permission before the first photo is sent. When you use it, your cover and copyright-page photos are sent through our server to Anthropic, which provides the Claude AI model, so that it can read the text in them. We do not store the photos on our servers. The text that was read is kept with your account and is deleted with it; we also count successful readings to apply the monthly free allowance. Anthropic processes the photos under its own commercial terms and privacy policy. Photograph only the book and avoid including personal material. To find edition details, the title, authors and language read from a book may also be sent to Anthropic. Always check results before saving.

Book lookups and cover downloads

To identify a book, Bookibis checks your own library first, then the Bookibis editions catalogue and public book catalogues such as Google Books and Open Library. These services receive the ISBN or the title and author being looked up, not your library. Cover images are downloaded from the addresses those catalogues return. When you are signed in and save a book with an ISBN, its bibliographic facts may be added to the shared Bookibis catalogue so other readers can find the edition: title, authors, publisher, translator, language, year, printing, pages, genre and a public cover link. Your notes, shelves, copy details, account and photos are never part of this, and the contribution is not linked to you.

Purchases

Apple’s App Store processes payment. We do not receive your payment-card details. RevenueCat manages Pro entitlements and restoration using transaction and purchase history, app user identifiers, and SDK device and request information. Signed-in Supabase user IDs are linked to RevenueCat; purchases without sign-in can use its anonymous app user ID. RevenueCat may also receive basic device information needed to verify purchases. Our server can check RevenueCat and receives purchase webhooks to maintain Pro status. Storefront country and currency can be processed by purchase services. These uses support purchases, restoration and entitlement checks, not advertising.

No advertising or cross-app tracking

Bookibis has no ads, advertising integrations, third-party analytics SDK, or app behaviour analytics events. We do not sell personal data or use it to track you across other companies’ apps and websites. Purchase management, account authentication, AI quota counts and normal service operation still process the data described above. This website uses Google Fonts, which receives ordinary font-request metadata, but no analytics, cookies, contact-form backend or advertising scripts. Your browser may cache fonts and static files.

Retention, export and deletion

Local data remains until you delete it or remove the app, subject to your device backups. Cloud library rows, uploaded covers, account data, quota records and cached extraction results are retained while your account exists; sync deletion markers can remain to propagate changes. In You, Delete account calls our delete-account function: it removes private uploaded covers, deletes the Supabase auth user and cascades private cloud records. Local library books are deliberately retained. Delete them separately if desired. Public shared bibliographic contributions do not identify you and can remain. App Store and RevenueCat transaction records are handled under their applicable retention obligations; deleting a Bookibis account does not cancel a store subscription. All users can export library details as a UTF-8 CSV from You using the system share sheet. The CSV contains no image files. You can also contact us about access, correction, deletion or a data copy; rights requests are not conditional on buying Pro.

Permissions, support and your choices

Camera access is used for book scanning and photos. Photo-library selection, where used, is limited to the images you choose through the operating system. Denying camera permission leaves manual entry available. You choose whether to sign in, request AI extraction, buy Pro, export a file or email support. Support email contains the information you send, plus editable version and device details in the draft; we use it to answer your request. Contact Pars Kunt at the email below for privacy questions or to exercise applicable data rights. We may update this policy and will change its effective date when we do.
