What happens if I delete my Application

I want to delete the logic, components, files and data of one of my applications. I would like to use the instance on the Springboard plan for another idea to play around. If I use the Delete App command will my instance named founderadvisor remain on the Springboard plan for further use?

When you delete your app, the database, files, logic - everything associated with your app (including the subscription it is on, such as Springboard) is deleted. If you would like to maintain your Springboard subscription, do not delete the app. Instead, clear the database, API services, UI, etc. and start over with your new idea.
