What Tack Does
Colour-Coded Notes
Assign colours to your sticky notes to visually organise by project, priority, or category.
Keyboard-Driven
Create, navigate, and manage notes entirely from the keyboard. Arrow keys, shortcuts, and quick entry keep you in flow.
Subtasks
Break tasks down into subtasks with checkboxes. Nest work inside each note without switching apps.
Progress Tracking
Each note shows a progress indicator based on completed subtasks so you can see status at a glance.
Avoid Zones
Configure areas of your screen that Tack won't place notes into, keeping desktop widgets and other tools clear.
Fully Local
No account, no cloud, no telemetry. All notes are stored as a JSON file on your Mac. Nothing ever leaves your device.
Your Data Stays on Your Mac
Tack does not collect any data. There is no account creation, no analytics, no crash reporting, and no network requests. All notes are stored locally on your Mac in a single JSON file under ~/Library/Application Support/Tack.
Deleting the app removes everything. There is nothing to unsubscribe from and no data to request deletion of.
