Overview

The Kobo database is a SQLite database located at /mnt/onboard/.kobo/KoboReader.sqlite. It contains all book metadata, reading progress, and user annotations for books purchased from the Kobo store or synced through Kobo's ecosystem.

The plugin reads from this database to pull reading progress into KOReader, and writes to it to push KOReader's progress back to Kobo.
