The very small amount of data collected from this website (your name, email address and anything else you choose to add) is sent directly to Wufoo whose privacy documentation you can inspect here. They will never contact you directly and they will never pass on your details to anyone else.
Both this website and theirs is "Secure" meaning that your data is sent encrypted and this you can see from the "https" label at the beginning of the website name. (Unsecured websites only have "http" at the beginning but the additional "s" stands for "Secure")
Should you have any questions about the security of your data feel free to contact the Webmaster.
