Profiles and your data

Backups and storage

Katari keeps automatic backups, your own comics and downloads in one folder you choose.

The storage folder #

Setup asks for it, and Settings › Data and storage › Storage location changes it. Give Katari a folder of its own; it fills it like this: 

Katari/
  autobackup/                      automatic backups
  downloads/                       downloads
    Pepper&Carrot (EN)/            comics, one folder per source
    Blender Studio (EN) [anime]/   video
    Project Gutenberg [book]/      books
  local/                           your own comics

Inside downloads/, each title has a folder of its own. After moving or deleting files there yourself, select Settings › Advanced › Reindex downloads so Katari notices.

Back up #

  1. Open Settings › Data and storage and select Create backup.
  2. Tick what to keep: library entries, chapters, history, categories, all read entries, app settings, extension stores and source settings.
  3. Include sensitive settings (e.g., login tokens) adds logins and other private settings. Keep a backup with them somewhere only you can reach.

With more than one profile, the screen also lists them, all ticked. Untick the ones to leave out. Locked ones ask to be unlocked when you select Create.

Create backup

Automatic backups #

Katari backs up every profile by itself every 12 hours and keeps the last four in autobackup/. Change how often under Automatic backup frequency.

Android

Backups run in the background, also while Katari is closed.

Linux

Backups run while Katari is open. One missed while it was closed runs when Katari next starts.

Each app names its backups after itself, so they can share one folder: katari_2026-10-13_09-30.tachibk from Katari, katari.foss_… from Katari FOSS and katari.desktop_… from Katari for Linux.

What a backup leaves out #

Left out After a restore
Downloads Keep the storage folder, or download again
Extensions and their trust Install them again. Ones that didn't come from a restored extension store need trusting again
Translation servers and API keys Enter them again
Text recognition models Katari offers to download them again when a page needs them
Sensitive settings, unless ticked Log in to sources again

Restore #

  1. Select Restore backup in Settings › Data and storage, or I have a backup in setup, and pick the .tachibk file.
  2. Choose what to bring back: library, categories, app settings, extension stores, source settings.
  3. If the backup holds several profiles, untick the ones to skip. Each one is either added as a new profile or merges into the profile it came from, and locked ones ask to be unlocked first.
  4. Katari lists the extensions the backup's titles need, and after the restore the Library offers to install them.

Restoring doesn't switch the profile you're using. Backups from Mihon and Tachiyomi restore the same way. Old JSON backups don't.

Move from Mihon #

Backups from Mihon restore like Katari's own. Coming from Mihon covers the whole move, extensions included, and on Android downloads too.
