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.
The difference is that secure / SSL subscription will use HTTPS protocol to show the form and capture the data through the encrypted channel.
This way no one can see what you are submitting nor what was asked from you.
What I would suggest is to always use secure submissions if you are collecting sensitive data such as patient records and similar.
The regular submissions that allow you up to 100 submissions per month, are opened like most websites do over HTTP protocol.
This means that if someone was to record the data being submitted by someone, they could see, but if the data submitted is not something sensitive, you can use the regular submissions.
Do let us know if you have any further questions in regards to this and we would be happy to answer them.
