Files on disk

Everything Splitkick knows is a file on your disk. There is no database, no account and no telemetry. Back it up, read it, move it.

App data folder

The app data folder is ~/Library/Application Support/app.splitkick.desktop/ on macOS, named after the app's bundle identifier. Jean's folder (com.jean.desktop) is separate; the first-start import copies from it and never writes to it.

Path	Content
projects.json	All projects, folders and worktrees, with their labels and settings
sessions/index/<worktree id>.json	The list of sessions in a worktree
sessions/data/<session id>/	One folder per session: metadata.json plus the conversation and run history
pasted-images/, pasted-texts/	Attachments you pasted into a session
session-context/, combined-contexts/	Saved contexts
schedules.json	All scheduled jobs, one-off and repeating

Writes are atomic (temporary file, then rename), so a crash never leaves a half-written file.

Worktrees

Worktrees exist only in git projects; a plain project has none. They are git worktrees under ~/splitkick/<project name>/ by default. Each project can use a different base folder (project settings). The project's own checkout is never moved. Worktrees imported from Jean stay where they are (~/jean/<project name>/).

Agent data

Each agent CLI keeps its own login and history in its own place (for example ~/.claude, ~/.codex). Splitkick reads what it needs from there and does not copy it.

Retention

Splitkick keeps sessions and their history until you archive or delete them. There is an archive setting for old sessions; its default keeps everything. See Archived items.

To keep a copy of your sessions on other devices, set up a session backup into a synced folder. The backup never deletes.
