Backups & Sync

Your library is yours — back it up like it.

What's in a backup

A backup includes essentially everything you've done in the app:

• Library entries, categories (including per-category update schedules and locks), and reading progress
• Chapter read states, bookmarks, and your chapter notes
• All your customizations — edited titles/authors/descriptions/genres, per-manga reader settings (direction, mode, color filters, preload), completed/dropped flags
• Tracker links — your MyAnimeList, AniList, Kitsu, MangaUpdates and Shikimori entries, with their scores, statuses and progress — plus reading history and settings

The one deliberate exception: custom cover image files are device-local (the paths wouldn't exist on a new phone), so re-pick covers after restoring to a different device.

Tracker links needed backup format v5

Backups written before format v5 did not contain tracker links at all, so restoring one leaves your library untracked and the tracker chips empty. That was a real bug, not a limitation — it is fixed, but a backup file made by an older build cannot have data in it that the older build never wrote. If you have an old backup you rely on, take a fresh one.

Local backup & restore

Settings → Backup creates a backup file wherever you point it (SAF — so SD cards and USB drives work). Restore from the same screen.

You can also pick exactly which sections go into a backup, or get applied from one, on both the backup and restore dialogs — library entries, chapters, categories, tracking, preferences, OPDS servers, feed, and tracker sync settings.

Backups are plain versioned JSON (currently v5), which is also why they are the app's data-portability story: anything that wants to read your library outside this app reads a backup, not the internal database. Newer app versions restore older backups cleanly.

Scheduled cloud backup (WebDAV)

Point the app at any WebDAV server — Nextcloud, ownCloud, a NAS — and it uploads backups on a schedule. Credentials are stored encrypted. This is the recommended way to survive a lost phone.

Coming from Tachiyomi?

The app imports Tachiyomi/Mihon backup files directly — library, categories, progress, and tracking links carry over. Combined with the shared extension ecosystem, switching takes minutes.

One thing to expect: an imported backup names Tachiyomi's sources. Entries whose source you haven't installed here will show as unavailable until you install the matching extension, or point them somewhere else with Migration.

Reading-position sync

Mid-chapter positions queue locally and ride along with backups, so picking up on another device puts you close to where you left off.

An honest note on privacy

Backups contain your full library and reading history. They're your data and they only go where you send them — but treat a backup file with the same care as the library itself.
