Privacy Policy - Booklio
Booklio respects your privacy. This Policy explains what information may be processed, how it is used, and your rights when you use the mobile application on iOS and Android.
1. Data Processing Overview
Booklio is designed to keep core app data on your device where possible. We do not sell personal data and we only use third-party services where they are needed for the features described below.
2. Locally Stored Data
The app may store data related to book discovery, barcode scanning, personal library management, reading progress, notes, quotes, ratings, goals and statistics locally on your device. This data is used to provide app features, remember preferences and support offline usage where available.
3. Processing Purposes
- Provide core app functionality
- Remember user preferences
- Support offline usage where available
- Process purchases or premium access where applicable
- Improve stability and prevent abuse
4. Third-Party Services
The app may use the following third-party services or providers: Google Books API, Open Library API, OpenAlex, Crossref, openBD, NDL Search, Rakuten Books API, Kakao Book Search API, German National Library (DNB) SRU, Bibliotheque nationale de France (BnF) SRU, Inventaire.io, BrasilAPI, Biblioteca Nacional de Portugal (PORBASE), K10plus (GBV), Sudoc (ABES), FantLab, OPAC SBN (ICCU), Cloudflare Workers, Google AdMob, Apple App Store and Google Play. These services operate under their own privacy policies.
When you scan a barcode or search by ISBN, title, author or DOI, the relevant search term may be sent to book metadata providers to retrieve title, author, publisher, cover image, description and similar book information. Some regional book lookups are routed through our Cloudflare Worker metadata proxy so the app can access provider APIs reliably. Your personal library content, notes, ratings and reading progress are not sent to book metadata providers for this purpose.
5. Advertising and Tracking
The free version uses Google AdMob to display banner and interstitial ads. The Google Mobile Ads SDK may automatically collect and share IP address (which may be used to estimate general location), app and ad interactions such as app launches, taps and ad views, diagnostic and performance information, and device or account identifiers such as advertising identifiers. Google may use this information for advertising, analytics and fraud prevention.
Depending on your region, consent choices and device permissions, ads may be personalized or non-personalized/limited. We use Google’s User Messaging Platform (UMP) to request and store applicable advertising privacy choices. If consent information cannot be obtained, a required permission is not granted, or the consent flow fails, the app defaults to requesting non-personalized ads.
On iOS, the app uses Apple App Tracking Transparency (ATT) before allowing personalized advertising or access to the advertising identifier. You can change this permission in iOS Settings. Where available, free users can review or change Google advertising choices in Settings > Privacy & Legal > Ad Privacy Options. Availability depends on region and legal requirements. Pro removes banner and interstitial ads.
For more information, see Google’s Privacy Policy and your device’s advertising and privacy settings.
6. Purchases and Premium Features
Optional purchases, subscriptions or premium access may be processed by Apple App Store or Google Play. We do not receive or store credit card details. Purchase status may be stored locally or verified through the relevant store.
7. Data Sharing
We do not sell personal data. Locally stored app content is not shared with CAREO LIMITED servers. Limited data may be processed by third-party providers only as described in this Policy, including book lookup identifiers such as ISBN, title, author or DOI when you use metadata lookup features.
8. Data Retention and Deletion
Local data remains on your device until you delete it, reset the app, or uninstall the app. Store payment records, advertising data and analytics data are retained by the relevant providers according to their own policies.
9. User Rights
Depending on your region, you may have rights to access, correct, delete, restrict, or object to processing. Because most app data is stored locally, you can usually manage or remove it directly through the app or your device settings.
10. Data Security
We use HTTPS for external communications where applicable, route some provider API requests through a server-side metadata proxy where needed, and design our apps to minimize data collection. No software or device environment can guarantee absolute security.
11. Children’s Privacy
The app is not directed to children under 13. We do not knowingly collect personal data from children under 13. If you believe a child has provided personal data, contact us.
12. International Data Transfers
Third-party providers may process limited data in countries outside your own. Appropriate safeguards apply where required by law.

We may update this Policy if app features, third-party services or legal requirements change. Updates will be reflected with a new Last updated date. Continued use of the app implies acceptance of the updated Policy.
