01Information we collect
Flash Books does not collect any information about you. There is no account, and the app includes no analytics or advertising.
02How books are handled
The books you add are stored inside the app on your device. Imported source files are never changed. When you share a book, the app makes a temporary copy inside the app to hand to the destination you choose.
03iCloud sync
Sync runs only when you turn it on in Settings. Then book details, original files, collections, bookmarks and reading positions are stored in your own iCloud (your private area of Apple's CloudKit) and synced with your devices signed in with the same Apple Account. The developer cannot see the contents of this area.
You can delete this data with Erase iCloud Data in Settings. Deleting the app does not delete its iCloud data; you can also delete it from iCloud storage in iOS Settings.
04Network
The app uses the network only to sync with iCloud when you turn sync on, and to load external images and other resources a book refers to when you allow external content for that book. It never sends your books or reading history to the developer's servers or to anyone else.
05Children's privacy
Because the app collects no information from anyone, it collects none from children under 13.
