Questions
Are books or filenames uploaded?
No. The ZIP, package, chapters and images are read locally. Embedded scripts, CSS, fonts and external resources are blocked.
How are bookmarks saved?
Chapter/scroll position, bookmarks and preferences use the existing local IndexedDB state manager, keyed by a SHA-256 digest. The book itself is not saved; reopen it after refresh. State expires after 24 hours of inactivity and can be lost if browser storage is cleared.
Which EPUB features work?
Reflowable EPUB 2/3 with OPF spine and EPUB 3 navigation or NCX contents. DRM, fixed-layout fidelity, publisher CSS/fonts, audio/video and interactive content are unsupported. Raster images are bounded; SVG images are omitted.
