The plugin keeps two things in sync between your devices and the BookFusion cloud: your **reading position** and your **highlights**. Once a book is downloaded on more than one device, you can pick up exactly where you left off, and your highlights travel with you.

## What Syncs[​](#what-syncs "Direct link to What Syncs")

-   **Reading position** — resumes where you left off, regardless of which device you last read on.
-   **Highlights** — pushed to and pulled from BookFusion, and visible across all your connected devices and the BookFusion apps.

Bookmarks are not synced

Only reading position and highlights sync today. See [Troubleshooting & FAQ](https://docs.bookfusion.com/docs/KOReader/koreader-troubleshooting#whats-supported) for the full scope.

## Manual Sync[​](#manual-sync "Direct link to Manual Sync")

From **Tools → BookFusion** you can sync on demand:

-   **Push reading position** — sends your current position from this device up to BookFusion.
-   **Fetch reading position** — pulls the latest position from BookFusion onto this device.
-   **Sync highlights now** — pushes and pulls highlights for the open book.

Manual sync is handy before you switch devices, or any time you want to be certain a change has been saved.

## Auto-sync[​](#auto-sync "Direct link to Auto-sync")

Turn on **Auto-sync** in the BookFusion menu to sync automatically in the background. With auto-sync enabled, the plugin will also fetch updates when you resume or unlock your device, so a book is up to date by the time you open it.

Switching devices

Let one device finish syncing before you open the same book on another. Opening a book on a second device while the first is still syncing can occasionally cause the position to jump. See [Troubleshooting & FAQ](https://docs.bookfusion.com/docs/KOReader/koreader-troubleshooting).
