If I delete the form does it delete all the stored applications?

alternately can i retain the form and just delete the applications?

Are you referring to the submissions of the form? If yes, you can delete the submissions and not the form. Please keep in mind that when you delete a submissions there's no way to recover it. You can download the submissions before deleting it. Here's a guide: How-to-Download-Form-Submissions-as-Excel-CSV-PDF
