Privacy Policy

Two types of information are covered by this policy:

  • Data saved on our server when you visit our site, or submit a form (such as the contact form)
  • Pieces of information we may store in your browser (known as "cookies")

Data Recorded on Our Server


Every request for a page, image, or any other file or data, from our site is logged. The information in the log may include your internet address, the type of browser and operating system you are using, the URI you are accessing and the page containing the link to it (if any), the date and time of the request, and in the case of any part of our site which requires a login, the username you used. In the event of an error, additional anonymous technical information may be logged.

Logs may be used by us to help us understand technical aspects of our site, for example performance and causes of errors, to analyse the ways users navigate our pages, for example which links are clicked most often, and to detect abuse of our site. This information is not used for advertising or similar commercial purposes.


If you use our contact form to send us a message, the text you type, together with some of the logging information described above, is both sent to us as an email and stored for a period on the server. The email copy may be kept indefinitely.


We use cookies on this web site to maintain the appearance that your page accesses belong to a single session. This is required for security as well as helping to improve the presentation. One cookie, called "_SESSION", is always used, and by using this site you accept our use of this cookie. Another, called "_COOKIES", is optional and enables you to control the banner message about cookies.

The details of the way these cookies are used are as follows:

  • _SESSION contains short term information to link your page accesses together into a single session. This cookie has a short lifetime (currently two hours) but it is renewed every time you access a page on the site. The information contained in this cookie is meaningless except to our server, and the contents are never passed to any third party, unless for legal or investigative purposes as described above. For normal site visitors, it never contains personally identifying information, although it may contain enough information to identify the machine from which the site is being accessed.

  • _COOKIES is a long-term cookie which is set only if you click on the button to accept cookie use in the banner message about cookies. If you do this, and if your browser keeps cookies for a sufficiently long time, the cookie banner message will not appear again until this cookie expires (currently one year). This cookie contains nothing other than a word indicating your acceptance (currently just "ok").
