# Tasks and subtasks

Subtasks nest one level deep. A task has one assignee and any number of labels.

## Details

- A concept in Stackly maps to one thing you can see on a board, so the words here match the labels in the app.
- Permissions follow the container: a person who can see a project sees every task in it.
- Archived items stay searchable and can be restored by an Admin.
- Names are not unique, so two tasks or two projects can share a title without clashing.
- Automations can read these concepts, and they appear in the API under the same names.
- Changing a concept for one project does not change it for the others in the workspace.
- The activity history records who changed what, and keeps entries for as long as the plan allows.
- The Free plan keeps the default behaviour; paid plans unlock the settings that change it.

Every plan includes the Stackly API, so the steps on this page work on Free, Pro and Business.
