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.
My understanding is that you are asking how to know if the form is encrypted or not. You can find out by opening the direct form wherein you'll see a lock icon beside the Submit button.
You can turn on or turn off the Form Encryption in the "Preferences > Advanced" tab.
Hope that helps. Thank you.
