What is a cookie?
"Cookie" is geek-speak for a tiny text file left on your computer by websites you visit.
If you know where to look, you'll find hundreds, perhaps thousands of cookies stored on your computer's hard disk. Each one is unique, and relates to a specific website.
Cookies are useful. When you do an online shop with your favourite supermarket and it greets you by name, that's because it detected the cookie stored on your computer from your last visit.
When you click the "Like this on Facebook" button on another website, and your Facebook account automatically opens up showing your profile, that's because of the Facebook cookies on your computer.
Cookies are used all over the place, for all sorts of reasons. They're used routinely by web developers everywhere (including us).
We use the following cookies on this website:
|__utma||1st party cookie. This cookie is typically written to the browser upon the first visit to your site from that web browser. If the cookie has been deleted by the browser operator, and the browser subsequently visits your site, a new __utma cookie is written with a different unique ID. This cookie is used to determine unique visitors to your site and it is updated with each page view. Additionally, this cookie is provided with a unique ID that Google Analytics uses to ensure both the validity and accessibility of the cookie as an extra security measure.||2 years from set/update.|
|__utmb||1st party cookie. This cookie is used to establish and continue a user session with your site. When a user views a page on your site, the Google Analytics code attempts to update this cookie. If it does not find the cookie, a new one is written and a new session is established. Each time a user visits a different page on your site, this cookie is updated to expire in 30 minutes, thus continuing a single session for as long as user activity continues within 30-minute intervals. This cookie expires when a user pauses on a page on your site for longer than 30 minutes. You can modify the default length of a user session with the _setSessionCookieTimeout() method.||30 minutes from set/update.|
|__utmc||1st party cookie. This cookie is no longer used by the ga.js tracking code to determine session status. Historically, this cookie operated in conjunction with the __utmb cookie to determine whether or not to establish a new session for the user. For backwards compatibility purposes with sites still using the urchin.js tracking code, this cookie will continue to be written and will expire when the user exits the browser. However, if you are debugging your site tracking and you use the ga.js tracking code, you should not interpret the existence of this cookie in relation to a new or expired session.||Not set.|
|__utmz||1st party cookie. This cookie stores the type of referral used by the visitor to reach your site, whether via a direct method, a referring link, a website search, or a campaign such as an ad or an email link. It is used to calculate search engine traffic, ad campaigns and page navigation within your own site. The cookie is updated with each page view to your site.||6 months from set/update.|
|api.twitter.com||3rd party cookies. We use several cookies on the homepage of the website to display our latest tweets.||2 years from set/update.|
None of the cookies used on our website collect personally identifiable information about you.
Session cookies allow websites to link the actions of a user during a browser session. They may be used for a variety of purposes such as remembering what a user has put in their shopping basket as they browse around a site. These session cookies expire after a browser session so will not be stored longer term. For this reason session cookies may sometimes be considered less privacy intrusive than persistent cookies.
Persistent cookies are stored on a visitors computer in between browser sessions which allows the preferences or actions of the visitor across a website site to be remembered. Persistent cookies may be used for a variety of purposes including remembering visitors preferences and choices when using a website or to target advertising.
First and third party cookies
Whether a cookie is 'first' or 'third' party refers to the website or domain placing the cookie. First party cookies are cookies set the particular website that the user has chosen to visit. Third party cookies are cookies that are set by a domain other than the one being visited by the user.
