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.
You have to enable autofill: http://www.jotform.com/help/227-How-to-Enable-Auto-Fill-Feature.
Or, use our session URL method: http://www.jotform.com/help/97-How-to-Save-Forms-to-Continue-Later.
Autofill will only work on the same computer and browser where the form is initially filled so if you want to give the users the option to continue later using any device and browser, please use the session URL method instead.
