What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Unfortunately, when you delete a submission, it will not be recovered anymore. This is because we let our users to have full ownership of their data, we do not do backups when the user deletes a submission. If it's deleted, it will be deleted in our servers permanently.
However, if you have setup email notification, you can use that as a reference for the missing submission instead.
I would also like to suggest that you integrate any one of our file sharing and storage services that we support (Dropbox, Google Drive, Box.net) to your form/s, this will let you have copies or backups uploaded directly to them in real time.
