Cookie Policy

This site, like many others, uses small files called cookies to help us customise your experience.

What are 'cookies'?

'Cookies' are small text files that are stored by the browser (for example, Internet Explorer or Safari) on your computer or mobile phone. They allow websites to store things like user preferences. You can think of cookies as providing a 'memory' for the website, so that it can recognise you when you come back and respond appropriately.

How does the CTA website use cookies?

A visit to a page on the CTA’s website may generate the following types of cookie:

Site performance cookies

This type of cookie remembers your preferences for tools found on the CTA’s website, so you don't have to re-set them each time you visit. These cookies aim to enhance the performance of the website.

Anonymous analytics cookies

Every time someone visits our website, software provided by another organisation generates an 'anonymous analytics cookie'. These cookies can tell us whether or not you have visited the site before. Your browser will tell us if you have these cookies and, if you don't, we generate new ones. This allows us to track how many individual users we have, and how often they visit the site. We cannot use these cookies to identify individuals. We use them to gather statistics, for example, the number of visits to a page.

Geotargetting cookies

These cookies are used by software which tries to work out what country you are in from the information supplied by your browser when you click on a web page. This cookie is completely anonymous, and we only use it to help target our content.

Registration cookies

When you register for a particular service or subscribe to a CTA newsletter, we generate cookies that let us know whether you are signed in or not.
Our servers use these cookies to work out which account you are signed in with, and if you are allowed access to a particular service. It also allows us to associate any comments you post with your username. If you have not selected 'keep me signed in', your cookies get deleted when you either close your browser or shut down your computer. While you are signed into a CTA site, we combine information from your registration cookies with analytics cookies, which we could use to identify which pages you have seen on the CTA web sites.

Other third party cookies

On some pages of our website, other organisations may also set their own anonymous cookies. They do this to track the success of their application, or to customise the application for you. Because of how cookies work, our website cannot access these cookies, nor can the other organisation access the data in cookies we use on our website.

For example, when you share an article using a social-media sharing button (for example, Facebook) on the CTA web site, the social network that has created the button will record that you have done this.

How to control cookies

You can control and/or delete cookies as you wish – for details, see You can delete all cookies that are already on your computer and you can set most browsers to prevent them from being placed. If you do this, however, you may have to manually adjust some preferences every time you visit a site and some services and functionalities may not work.
