At any time you can delete your account at Exceed. Deletion of a project can be done only by the Owner of the project.
In order to delete your account at Exceed kindly go to Settings -> Project Settings or simply click here: https://leads.exceed.ai/#/Settings/project-settings
At the bottom of the page you'll find a Delete Project button:
Once you hit the "Delete project" button, a confirmation page will appear. You'll need to confirm the deletion by typing in "DELETE".
That's all :)
