Privacy settings for sensitive information

Hello, I am about to launch my bubble site that will include users entering sensitive information (address, phone number, etc). Are there any extra steps I have to take under the Privacy tab to protect this sensitive information? If so, what do I need to do, as I am confused by the roles you can create under the privacy tab. Thank you in advance!

You could try creating a field type ‘‘user’’ under current user and in the privacy role under "when’in put in "Current user’s’ 'user ’ ‘is’ Current user.

Thank you. Can you elaborate on what would doing this do?
