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.
If you're referring to the submitted pictures then yes, your files and submissions are private and secured. And they can be accessed by you and the person that you grant access to do so.
However, if you want to enable secure submissions (to encrypt the connection between your form and your submitters), then you need to use the secure version of your form. Please refer to this guide: http://www.jotform.com/help/63-How-can-I-receive-SSL-Submissions.
Also, please note that FREE accounts are allowed to receive up to 10 SSL submissions per month.
Let us know if you have further questions.
