None of the information you provide to Code Koala, either directly or indirectly, will be surrendered to any party unless required by law. Information gathered includes data you provide when submitting content to Code Koala, as well as data transmitted by your Web browser as an integral part of your browsing experience.
These data are transmitted to each site you visit in order to ensure that you receive the information you are looking for, and they are required to differentiate between visitors. Most of these data cannot be used to determine your identity, though your Internet Protocol (IP) address can. I cannot stop your computer from sending its IP address to my host, and attempting to do so could very well break the Internet :)
