The only thing we log is the request from you're browser (so you're public IP and what you request from the server) in our webserver logs. We use that to generate statistics for my personal usage to see how often pages are request and which pages are the most interested by the viewers (assuming the number of requests per page says something about the interest value of the page).
What about the cookies?
The only cookie which is used for this website is a small session cookie and one I use to edit this website. The session cookie is stored on you're computer and can be deleted without a problem.
What about the contact form?
Why no https?
We don't have https at the moment because our hosting package doesn't support it at the moment. But we are working on a migration.
