As you can see, this web site is open to the public. There is no registration for users here on the main site. We don't have a policy for use of personal data you provide on the site since you don't provide it. We don't set cookies. This site runs on a web server. When you browse to our site, our web server has to use your IP address so that it can send web pages to you. It is normal for web servers to log their activity, which means that your IP address will be stored for a period in the logs. An IP address usually isn't personally identifiable data and we make no use of it to try and identify callers.
We have a wiki with security set up on it, so users who want to contribute information may ask us to register them for user accounts. Once this situation arises, we'll add a data policy to cover it.
