what information does jotform collect automatically from respondents to my form?

Hello,

The basic information collected by JotForm from respondents, aside from the filled-up form submissions, are the date and time when the form was submitted and the IP address of the one who made the submission. There likewise is a submission ID for reference of the submission but this is automatically generated by the system, rather than collected.

You can get these information when you check your form's submissions page. If you need to know how to view the submissions page, please refer to this guide: https://www.jotform.com/help/269-How-to-View-Form-Submissions

Thanks.
