Does the form just send an email or will it save data in a database?

That depends on how it is setup but it can do both.

When the form is submitted the submissions will be stored in your Submissions page.

If the Notifications were set up, then you will receive an email as well.

But you can choose not to create Notifications and then only view submissions in Submissions page.

If you have any further questions please let us know.

Thank you!
