Introduction

This website makes use of cookies. These are text files containing small amounts of information which are downloaded to your device when you visit a website. Cookies are then sent back to the originating website on each subsequent visit, or to another website that recognises that cookie. Cookies are useful because they allow a website to recognise a user’s device. You can find more information about cookies at: All about Cookies and Your Online Choices.  For a video about cookies visit Cookies.

Cookies do lots of different jobs, like letting you navigate between pages efficiently, remembering your preferences, and generally improve the user experience. They can also help to ensure that adverts you see online are more relevant to you and your interests.  A list of the cookies used on this website is set out below.

Cookies for improving service by measuring traffic

We use Google Analytics, a web analytics service provided by Google, in order to find out how visitors interact with our website so we can improve it. Information is collected anonymously and website trends are reported without identifying individual visitors.

Cookie name  and Purpose

__utma

Keeps track of the number of times a visitor has been to the site, when their first visit was, and when their last visit occurred. It expires after two years.

__utmb and __utmc

The B and C cookies work together to calculate how long a visit takes.

__utmb takes a timestamp of the exact moment in time when a visitor enters a site, while __utmc takes a timestamp of the exact moment in time when a visitor leaves a site.

__utmb expires at the end of the session. __utmc waits 30 minutes, and then it expires.

__utmc has no way of knowing when a user closes their browser or leaves a website, so it waits 30 minutes for another pageview to happen, and if it doesn't, it expires.

__utmz keeps track of where the visitor came from, what search engine was used, what link was clicked on, what keyword was used, and where they were in the world when the website was accessed. It expires after six months.

Squarespace websites drop a single tracking cookie called "ss_lastvisit" to allow its statistics module to determine if a website visitor is unique. This expires after seven days. See What is a unique visitor? for more information.
