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.
No, there is no way to avoid storing the Uploaded files in Jotform. You can delete them, but that would imply to delete the whole submission of the uploaded file.
If you do not feel comfortable having your submission data and especially the uploaded files in Jotofrm and you prefer to store it in Dropbox, then you may consider to use our Auto Delete Submissions app: http://apps.jotform.com/app/auto_delete_submissions
That will delete your submissions from your Jotform account as soon as they arrived, but you need to make sure to connect the Dropbox integration first, otherwise your submissions will be delete and they cannot be retrieved.
