Privacy

Your tasks never leave this Mac.
There is no server to send them to.

  • No account, no sign-up — nothing to create and nothing to leak
  • No analytics and no tracking code, in any build
  • The AI assistant runs on your machine through Ollama
  • Export to JSON or CSV whenever you want to leave
Habits — weekly checks and streaks
Habits — weekly checks and streaks

And the rest

  • Pomodoro sessions and habit streaks, tied to the tasks they belong to
  • Publish dated tasks to iCloud or Google Calendar and read them on your phone. Off by default
  • Korean and English throughout — tomorrow 3pm and 내일 오후 3시 both parse
  • Recurring tasks, reminders, subtasks, tags, priorities, and markdown notes
