The web pages here do not include content from other web sites that may set a cookie of their own; ie you should not get third party cookies, these are cookies from other sites that may be used to track you as you move around the Internet. It was concerns about these that led to the EU passing 2002/58/EC and revised as 2009/136/EC; the purpose was to protect individuals' privacy, in particular protection from cross site tracking ‐ eg: search for a sofa on one site and be shown good deals of sofas when you first arrive at another web site.
This site does not ask for permission before setting a session cookie since: these do not provide long term memory of your visit or what you were doing; neither is the cookie available to any other web site.

Apache, and other, log files will usually be kept for about a month. If a problem is being investigated they (or parts of) may be kept for longer.
These Apache log records are analysed by AWStats to provide aggregate statistics about topics such as: web site performance; the most popular pages & busy times of day.
More permanent information may be kept as a result of you filling in a form (eg enquiry) or sending an email. This information will only be shared with our staff and, on a needs to know basis, web site maintainers. We will, reluctantly, share records with law enforcement, or others, as required by UK law.
In addition to Apache (web access) logs, other sub-systems will record activity. As with web logs these are kept for similar durations & reasons: performance and problem analysis. Often IP addresses will be logged.
