Yes. I collect only your name and email address, and I do not distribute that to anyone else. I do not collect your credit card information, or any other financial information. I use a trusted vendor, PayPal, for payment functions so that I never have to see your credit card or other financial information. Since I don't collect your financial information, I can't expose it to anyone else.
For additional security, all of my sites now use a secure protocol that encrypts all information that flows over the net. (https:// for those who want detail)
