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.
Since you have subscribed over Stripe, you can simply go to your Account -> Billing and then click on Free plan and you will be downgraded from your current plan.

Please do note that your subscription will no longer be grandfathered if you cancel it so if you decide to upgrade in the future, the new pricing will be applied.
If you happen to have any difficulties downgrading to free, please do let us know and we would be happy to assist you with the same.
