561021 Joomla Form Data security problem

I have an extension called CK Forms on the website dynamicsecuritygroup.com. I have just been informed that all of the contact data from the form is accessible and searchable by Google, even though the admins needed a password to access this data. I need to secure this data, and make it no longer Google searchable. If you Google this phone # 2126710770 you will see that Living Social Forms is the 2nd hit.
