Where Does the JW Library App Store Data?
JW Library keeps downloaded publications, videos and study progress in private storage on Android and iOS.
Last updated
Jehovah's Witnesses Library app uses the jwlibrary package on Android with a matching iOS build. Private storage holds downloaded publications, videos and study progress. Publications come from the library catalog and stay on the device for offline reading. Study progress stays with the local install.
Media files account for most disk use. The app library manager is the place to add or remove downloads. Folder poking is not needed and does not help. The iOS bundle is unverified, so quote App Store ID 672417831 when asking support for help.
