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.
Are you referring to sub-users you created where you share your forms? Or those who fill out the forms?
The owner or the user who created the form is the only one who can view, edit and delete the submissions displayed in the Submissions page, unless you provide the edit_link to your users where they can update their submissions. Other than that, you are the only one who can delete the submissions.
I hope this helps. Let us know if you need more information on this.
