Cookie Policy

In order to make our website work properly, and to service our visitors with the the most relevant products and services to our site visitors, we place small data files called cookies on your device. This policy provides you with information about cookies and how to control them for this website.

What is a cookie?

A cookie is a small amount of data, often containing a unique identifier, that is sent to the browser of your computer, tablet or mobile phone (here referred to as a "device") by a website and stored on your device's hard drive. Each website can send its own cookies to your browser if your browser settings allow it, and your browser allows the originating website to access cookies it has already sent to you to record online traffic flows and develop records of user activity.

Users can set their device to accept all cookies, send them a notification when a cookie is issued, or never to receive cookies. In the latter case, the user will not be able to set some customized features and therefore will not be able to take full advantage of all the features of the website. Each browser is different, so check the "Help" menu of your browser to learn how to change the cookie settings.

Cookies help us enhance your experience when using the website, for example they help us to ensure that you are served content in your own language. They also help us understand how people use our site, such as which pages are most popular, so that we can better serve our site users and members.

Types of cookies

First party cookies
First party cookies are set by the website you are visiting and can only be read by that site. Later in this policy we will provide a comprehensive list of all first party cookies set by GTT.

Third-party cookies
Third-party cookies are set by a company other than the owner of the website you are visiting for purposes such as collecting information on user behaviour, demographics, or personalized marketing. When using our website, you may encounter embedded content, such as Vimeo or YouTube videos, or you may be directed to other websites for such activities as event and webinar registrations, surveys, or for job applications. These websites and embedded content may use their own cookies. We do not have control over the placement of cookies by other websites, even if you are directed to them from our website. 

Session cookies
Session cookies are only temporarily stored during a browsing session and are deleted by the user's device when the browser is closed. 

Persistent cookies
This type of cookie is saved on the computer for a fixed period and is not deleted when the browser is closed. Persistent cookies are used when it is necessary to know who you are for more than one browsing session. For example, we use this type of cookie to store your settings, so that they are stored for the next visit.

How does GTT use cookies?

The cookies set by the GTT websites (first party cookies) are used for a variety of reasons which we’ve categorised as essential, analytics and marketing.

The information provided by cookies can help us analyse the profile of our visitors and offer you a better use of the site. For example, if you are contacting us through the online contact form, we can see how you went through the site and what pages you visited before making the contact.

We use three categories of cookies as follows:

  1. Essential cookies: ensure the website works properly for our visitors + safeguards the security of the site and by extension our visitors
  2. Analytics cookies: non-personalised, used for analysis, helping us to understand how visitors use the site and thereby how we can improve it
  3. Marketing cookies: to enable us to understand how users are interacting with our Marketing comms (landing pages, emails, online advertising using search engines & 3rd party vendors)

We use Google Tag Manager, a script (tool) that facilitates the installation of non-essential analytics Cookies (see below) and marketing cookies. It is not a cookie, it is essential to the proper functioning our site, and it does not have an expiration date.

Below you can see the list of cookies set by the GTT websites (first party cookies), the function for which each one is used, along with the time period that each cookie will remain active for.

Essential cookies

These cookies are essential for enabling user movement around our website, providing access to regional and language specific content, in addition to maintaining the security of our site to best protect our visitors.

Analytics cookies

We use Analytics cookies to collect information about how visitors use our website. These cookies collect information in the aggregate to give us insight into how our website is being used. We anonymise IP addresses in Google Analytics, and the anonymised data is transmitted to and stored by Google on servers in the United States. Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google's behalf. Google will not associate your IP address with any other data held by Google.
