Cookies are small text files placed on your device by websites you visit. They are widely used in order to make websites work, or work more efficiently, as well as to provide information to the owners of the site.

This page describes the types of cookies and how they are (or not) used on our website.

Mandatory cookies

These cookies are essential for us to run our website successfully, so we do not provide you with an option to opt out of these; they are an important part of providing you with an effective service. By visiting our website you consent to us creating and retrieving these cookies.

With most web browsers it is possible to configure your internet browser so that it can disable cookies entirely. How you do this will depend on the internet browser you use; however it will result in our website not operating correctly.

System cookies

These cookies are created each time you visit ensims.com and are automatically deleted when you leave our website and close your browser. They help with the smooth operation of the website. They also make sure that any selections you make during each browsing session are remembered. The website simply wouldn't work without these.

Cookies to track your cookie preferences

If you express preferences about whether or not to receive certain types of cookies, we’ll use a cookie to store this preference.

Web analytics cookies / marketing effectiveness cookies

These cookies allow us to understand general customer behaviour on ensims.com; such as which bits of our website customers use, where they exit the site and, if anything goes wrong, where it happens; helping us to make our website better.

We also track how customers find our website, for example which search engine was used or which online adverts were clicked on before visiting us, helping us understand our marketing effectiveness.

Data is anonymised and aggregated so we can monitor trends and count visitors rather than tracking individual visitors. They have no impact on what you see on the website and do not store or track any of your personal data.

Cookies for personalising your experience on ensims.com

These cookies allow us to understand the way you specifically use our website and tailor your experience on ensims.com. For example, by understanding the searches and selections you make on our website, we may be able to show you pages that are more relevant to you. If you have searched for a particular course on our site we may show you related courses.

Cookies for optimising our web content

We sometimes may wish to test a change or new feature on the site to see if it is effective before rolling it out to all of our users. Cookies allow a random sample of site visitors to see it one way, and a different group another, and ensure you consistently get the same visit on repeat visits.

Controlling and deleting cookies

If you wish to restrict or block the cookies which are set by our website, you can do this through your device's internet browser settings. Guidance and advice on managing cookies.
