JotForm Support won't give 2 cents about your data safety. They won't even care if you make a phishing form. Because guess what, they will send your social security number, full date of birth, physical address, phone number, and any given number of data fields to email addresses you provide without even checking that you own the email address unless "form owner use/add in the form".
I pointed this security flaw to their support, BECAUSE I received such an email without any prior knowledge, solicitation, use of the site, etc. And their support staff response? "Please contact the form creator directly, since JotForm is not responsible for the content of that form. The form creator may have their own privacy policy."
Right, sensitive data is coming from their website and they won't take responsibility for what people are doing on it. Well, here's my take on that: go use the website at your own risk, your identity, your livelihood. If you want your Social Security Number known by a random stranger, go ahead.
