Privacy policy
Read, listen and keep learning.
Your library
Imported books, audio, reading progress, bookmarks, notes and preferences are stored locally. No Knowledge Companion online account or automatic cross-device sync is provided. Chosen library credentials are stored in Apple Keychain. We do not upload your books to an operator-controlled library.
Connections and backups
Your chosen OPDS/Kavita servers and podcast/news publishers receive network requests, including IP address and requested resources. Downloads and news excerpts may be cached. Full articles open at their publisher. Manual backups go to the folder or cloud provider you select; that provider’s terms apply. Device backups follow your Apple settings.
Advertising and choices
Google AdMob supplies banners. The app requests non-personalized ads. Google may process IP-derived general location, device identifiers, ad interactions, crash and performance data for advertising, measurement and fraud prevention. Non-personalized ads still process data. Google UMP handles applicable consent; reopen Advertising privacy in Settings when available. The app does not request precise location or Apple tracking permission, and does not intentionally send books or reading history for ad targeting. Verified Remove Ads purchases hide app banners.
Purchases
Apple processes optional purchases. The app checks verified transactions and entitlements; the developer does not receive your payment-card details. Restore Purchases restores eligible permanent purchases. Tips are optional repeatable purchases, not subscriptions, and do not remove ads.
Support and website data
Support is optional. In-app email sends only the message, reply details and attachments you choose; optional diagnostics include build, iOS and language. The website form sends your message, category, app and optional reply email through Cloudflare and Resend to our private support inbox. Request references, hashed IP addresses and delivery status support anti-spam and retries. Hosting providers process normal request/security logs. These pages add no advertising or analytics scripts.
Retention, deletion and contact
Local data stays until removed or the app is deleted; exported backups and Keychain entries may remain. Delete exports separately and remove saved library credentials using the available connection controls. Support messages and service metadata remain until manually deleted; no automatic expiry is promised. Use the support form to request access, correction or deletion of support data, with your reference and reply email. Providers apply their own retention rules. Do not send passwords or sensitive documents.
Children and changes
This is a general reading app, not a service designed for children under 13. A parent should contact support about a child’s submitted personal data. Features and providers may change; this page will be updated. Local voice availability depends on Apple and downloaded voices. Widgets show titles only when you add them.
Sharing and offline articles
Sharing sends the selected book file, book details or article link to the app you choose. Full B2D articles and included images can be downloaded for offline reading, removed in the reader, and included in manual backups. Interactive tools need internet. Other publishers open at their websites.
