Project Deletion

Per our data retention policy, depending on your plan, we retain build data for the following periods :

• Free Plans: 90 days
• Performance and Custom Plans: 180 days
• Scale Plans: 2 years

You can also set custom data retention periods for artifacts, workspaces and cache items by navigating to the Usage Controls in the Plan portal:

https://app.circleci.com/settings/plan/vcs/organisation/usage-controls

If you need a project deleted sooner than our policy outlines, please follow this guide. Deleting a project will remove the complete build history.

You can delete your project in Project Settings by scrolling to the bottom of the page and clicking "Delete Project"
