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.
As I've mentioned in one of the threads, we can't integrate directly JotForm to your database unless you purchase the licensing for self hosted form builder. But, all submission data of forms are saved to our servers, which are secure. We got very powerful cloud of servers whose storage is encrypted which provides security protection.
If you use SSL/secure form URL to accept submission, the data transferred from your browser to our server will also be secure. We support high-grade 256-bit encryption.
You have option where you can select if you want the form data to be secured. You can use the secure / SSL form URL or embed script.
Here is a guide on how to receive SSL submissions: http://www.jotform.com/help/63-How-can-I-receive-SSL-Submissions
If you want your form user to know that their data will be sent securely, you can add enable security certificate seal in your form. Here is a guide which you can refer: http://www.jotform.com/help/131-Enabling-Security-Certificate-Seal-on-Secure-Forms
I hope this helps. Let us know if you need more information on this.
