Your privacy and security is our top priority at Billeo.
We believe that you should own your personal information, not us. Other than your e-mail address and zip code, we ask for no personally identifiable information.
Passwords and credit card/bank account details are kept on your own PC as encrypted data. Saved pages are encrypted and kept on the Billeo servers. We constantly monitor the latest in security to ensure that your data is never at risk.
