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 do not explicitly set someone to be able to change your jotform, no one would be able to do that for you, unless they are logging into your account directly.
If that is not what you have meant, do give us a bit more details in regards to this and welcome to JotForm :)
