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, once the submission is deleted, it can no longer be retrieved.
However, there are ways to back-up your data so that next time, you will have a backed-up data. Here are some ways:
1) Download your data to Excel.
2) Integrate your form to Google Spreadsheets.
3) If you want a back-up or copy of file upload submissions, you can try integration with Dropbox, or integration with Google Drive.
If you have questions, please do let us know.
