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.
Jotform has a very powerful cloud of secure servers and provides a very high-security level through out our hosting provider's servers for stored data. JotForm provides the form URLs with SSL by default and our SSL certificates support high-grade 256-bit encryption.
The submissions received for your forms cannot be viewed unless you are logged into your account or by the other account that has been shared by you using sub-account users.
For additional security, you may also consider using the Form encryption that encrypts the form submissions. These encrypted submissions can only be viewed when the private key is supplied that is generated while enabling the form encryption. You may consider that the form submission is lost if the generated private key is lost. More information on the encrypted forms is available at the following guide:
Hope this information helps!
