Files and data

Kimochi keeps everything on your computer, in its data folder, under the app id dev.kimochi.app:

System Data folder
macOS ~/Library/Application Support/dev.kimochi.app/
Linux ~/.local/share/dev.kimochi.app/, plus ~/.config/dev.kimochi.app/ and ~/.cache/dev.kimochi.app/
Windows See the note below
What Where
Settings (including your DeepL key and window positions) settings.json
The Log, sessions, stats and Notebook (no account) The data folder itself: sessions.json, sessions/, stats.json and friends
The same, per signed-in account profiles/<server>-<account>/
Downloaded dictionary engines extensions/<engine>/<version>/
Downloaded OCR models models/<engine>/
The sync log sync-log.jsonl
Dictionaries you import The app’s web storage (IndexedDB), managed in the engine’s settings

Captured images are held in memory while Kimochi reads them and aren’t saved to disk (images you add to the Notebook are). Deleting the data folder removes all of it.

  • With an account, Sync keeps a copy on the server, and Settings → Account → Export your data saves it as a ZIP. See Sync and backup.
  • Without one, copy the data folder while Kimochi is closed.
  • Yomitan dictionaries and settings can be exported from Yomitan’s own settings (its Backup section).
