JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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, the answer is No. It is not possible to recover the deleted submissions of a JotForm. You may retrieve the submission data from the notification emails received if you have a notification set on your JotForm or integrated with Google Spreadsheet or cloud storage like Google Drive or DropBox, etc.
Hope this information helps!
