Current formats
The published release supports EPUB and PDF. Files must be valid and readable; damaged or unsupported packages may be rejected.
Import from Files
From the library, choose Add and select a file. Sharon creates an app-local copy so the book can remain available offline.
The file appears under My Files. Library search can find its title or author when that metadata is available.
Privacy and deletion
Sharon never uploads your whole personal file to any external service. When you use cloud reading, only the image of the requested page is sent, after your consent, as the privacy page explains. Removing a file from Sharon deletes the app copy and related local reading data.
Keep your original file when it matters. Sharon is a reader, not a backup service.
