Deleting a project is permanent and cannot be undone. Make sure to back up any important data before proceeding. Once deleted, you will no longer be billed for that project.
To stop being billed for any further usage, you can simply delete your projects. Follow these steps:
Go to your project's settings.
Scroll down to the bottom of the page.
Click on "Delete your project."
This will ensure that you are not charged for any future usage.
