Files and folders

kknow keeps data in two places: in each vault and in the app config directory.

In each vault

<vault>/
  *.md                  your notes
  attachments/          pasted and dropped images
  .kknow/
    sync.json           the snapshot of the last sync
    remote.json         the storage address, the conflict policy, the interval
    bookmarks.json      bookmarks
    themes/*.json       themes of this vault
    trash/<entry>/…     deleted notes and folders

kknow skips all hidden folders, for example .git and .obsidian. Sync does not copy .kknow/. Add .kknow/ to .gitignore if you keep the vault in git.

remote.json has no secret key. The window keeps the key in the system keychain.

App config directory

Platform	Path
macOS	~/Library/Application Support/dev.kknow.desktop/
Windows	%APPDATA%\kknow\
Linux	$XDG_CONFIG_HOME/kknow/, or ~/.config/kknow/

The window and the CLI share this directory.

File	Content
vaults.json	the vault list: names, paths, colors, labels
settings.json	language, theme, editor settings
keybindings.json	your changed shortcuts
commands.json	custom commands
files.json	standalone files
mcp.json	MCP server: on or off, the port, the token
themes/*.json	shared themes

Remove kknow completely

1. Remove the app.
2. Remove the app config directory.
3. Optional: remove the .kknow/ folder from each vault.

Your notes stay as they are.

With Homebrew, brew uninstall --zap --cask kknow also removes the config directory and the caches.
