When purchasing from Wunan Foundation Inc. your financial details are passed through a secure server using the latest 128-bit SSL (security socket layer) encryption technology. 128-bit SSL is the industry standard and used by all reputable e-commerce sites. SSL locks all information provided by you in an encrypted envelope. This makes it almost impossible to be intercepted by an unauthorised party, as long as your browser and local network support the use of encrypted data transmission. Your credit card information is retained by us only until the service you are purchasing has been delivered. It is then automatically deleted. If you have any concerns about our security policy or using your credit card on our web site you can contact us for more information or assistance.
