FoldBook privacy policy
Updated 12 November 2026. Publisher: CREVAL COMMERCE PTE. LTD. (Creval Digital Studio). This policy covers FoldBook on Google Play, package ai.foldbook.reader. The advertising and purchase sections describe version 0.2.0 and later. Earlier offline releases, including 0.1.17, contain no advertising or purchase SDK and do not request internet access.
Your PDFs and reading activity
FoldBook reads PDFs you choose through Android’s file picker or open from another app. Document locations, cover images, bookmarks, reading positions and preferences are stored on your device. FoldBook does not upload your PDFs or reading activity.
Advertising between books
FoldBook requires no reader account. In version 0.2.0 and later, free users may see a Google AdMob interstitial only when deliberately opening a different book from the library after a reading session. Ads are never inserted into a document, page turn, search or reading session. Reading works offline; if no ad is ready, FoldBook opens the book without waiting for one.
Google's advertising and consent services may collect and share IP addresses (which can indicate approximate location), device and advertising identifiers, app/ad interactions and diagnostics for advertising, analytics and fraud prevention. SDK communications use encryption in transit. FoldBook does not supply PDF contents, titles, file locations, bookmarks, search terms or reading positions to these services. The app does not request precise-location access.
Google's User Messaging Platform checks whether advertising consent is needed. Where applicable, users can accept, refuse or manage optional consent and reopen Advertising privacy choices in Settings. Ads are requested only when the consent service permits. Refusing optional consent may result in limited ads or no ads; reading tools remain available. See Google's privacy policy and Google's advertising controls for its processing, retention and international transfers.
One-time ad removal
When available in Google Play, Remove ads is a one-time, non-consumable purchase, not a subscription. The app displays the local price supplied by Google Play before checkout. Google processes payments; FoldBook does not receive payment card or bank details. The app verifies the signed purchase receipt and stores the receipt, purchase token, acknowledgement and entitlement locally to apply and restore ad removal. Pending or cancelled payments do not grant ad removal. Use Restore purchase with the same Google Play account after reinstalling or changing devices. Online checks reconcile entitlement, including refunds; a previously verified entitlement remains available offline.
Ad removal prevents FoldBook ad requests and displays. Google Play may still process purchase and transaction information to provide billing, restoration, security and fraud prevention. See Google's privacy policy. All PDF reading features remain free.
Storage and removal
Removing a document from the library removes the app’s library entry and leaves your original file in place. You can clear FoldBook’s local app storage or uninstall the app to remove its private data. Files stored in other apps or document providers remain under those providers’ controls. FoldBook excludes its private data from Android app backup and device-transfer rules.
Clearing FoldBook storage does not delete Google's advertising or purchase records. Use Google's privacy and purchase controls for those records; we cannot promise deletion of information retained by Google. Your Play purchase can be restored after local app data is removed.
