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.
If I understood you correctly, you want that your users are able to see data they have submitted. You can achieve that by creating a form Autoresponder. When you create Autoresponder, your users will receive email with data they have submitted. Inside of this guide you can find how to create a form Autoresponder: https://www.jotform.com/help/26-Creating-a-Form-Autoresponder
In case that you also want to allow your users to update their form submissions at a later date, please check this guide: https://www.jotform.com/help/40-How-to-Let-Users-Update-Their-Form-Submissions-at-a-Later-Date
Hope this will help. Let us know if you need further assistance.
