Does the widgets make my form secured?

Apologies - I'm just now circling back on this.
So the widgets to add, the terms and conditions and the esignature - does
that make the form more secure? Or are they just required when collecting
personal information? Are they in addition to what I have, or instead of?

The widgets are for the users. They need to agree that they're sharing sensitive information to your form. Please check our terms of use for more information: https://www.jotform.com/terms/

Is the form secured? Yes, the form is secured by default. For more information, please check this link: https://www.jotform.com/security/
