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.
We have a feature called auto-fill that helps you to meet this requirement. If the user has closed or refreshed the window accidentally while filling your JotForm, the data is stored locally on the system by enabling this auto-fill feature.
Please refer to the following guide that can assist you in enabling auto-fill feature.
Please get back to us if you need any further help. We will be happy to help.
