Cookie Policy

What are cookies?

Cookies are small text files which are downloaded to your computer, tablet or mobile phone when you visit a website or application. The website or application may retrieve these cookies from your web browser (eg Google Chrome, Mozilla Firefox or Safari) each time you visit, so they can recognise you, remember your preferences and provide you with a more secure online experience.

Generally, cookies are very useful and are a common method used by almost every website you visit because they help to make your online experience as smooth as possible. For security reasons, many websites will not function at all without the use of cookies (or other similar technologies, such as "web beacons" or "tags").

Cookies generally do not hold any information to identify an individual person, but are instead used to identify a browser on an individual machine.

If you prefer, you can restrict, block or delete cookies by changing your browser settings but that may mean that the website won't work properly

Managing cookies

Most internet browsers allow you to erase cookies from your computer hard drive, block all cookies (or just third-party cookies) or warn you before a cookie is stored on your device.

Please note, if you choose to block all cookies, our site will not function as intended and you will not be able to log in to your dashboard. If you have blocked all cookies and wish to make full use of the features and services we offer, you will need to enable your cookies. You can do this in your browser (see below).

Rather than blocking all cookies, you can choose to only block third-party cookies which will still allow our website to function as intended.
