Break down complex work
Start with one task, then add the steps underneath it when the work needs more structure.
Professional task planning for focused work
Turn personal work into clear, scheduled next steps.
duun is a professional productivity app for capturing tasks, breaking down complex work, keeping context close, and planning time without losing sight of what matters next.
Built for professionals who run on tasks
duun keeps the model simple: every item is a task. A task can stand alone, carry notes, be scheduled, be shared, or expand into the detailed steps needed to finish it well.
Keep context attached
Store decisions, references, and working notes directly on the task they support.
Share only what is relevant
Bring another person into a specific task so collaboration stays focused and unrelated work stays private.
Plan time from the task
Assign time to important tasks in duun, then optionally sync selected scheduled tasks to Google Calendar.
Controlled AI assistance
Connect AI clients through MCP with scoped permissions for actions such as reading, creating, editing, scheduling, or completing tasks.
Designed for private work
Task titles, notes, comments, and schedules are encrypted before storage, and optional integrations stay under user control.
Privacy and connected services
Your tasks stay private. Integrations stay optional.
duun encrypts task content before storage and only uses third-party services when they are needed for account access, billing, support, or an integration you choose to enable.
Google sign-in
If you choose to sign in with Google, duun receives basic account details such as your email address, name, avatar, and Google account identifier so it can create your account, sign you in, and protect account access.
Optional Google Calendar sync
If you connect Google Calendar, duun uses the granted calendar access to show selectable calendars, sync scheduled tasks you choose, remove synced events when sync is turned off, and check free/busy availability when enabled.
duun does not use Google Calendar data for advertising, and connected calendars can be disconnected from settings.
