JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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.
I'm not quite sure if I fully understand your question.
Are you asking if your form will retain all its data if you don't renew your jotform subscription?
Or are you asking if there is a way to stop the form from being used further and keep its data?
I want to make sure I’m not getting charged for this form as long as its disabled. How do I make sure of this?

Seems like you want to cancel the subscription since you are not using the form (it looks disabled) so, I went ahead and cancelled. You should not be charged any more.
