Cookies

Last updated: 4 March 2021

We rely on cookies to make our site work, understand where we need to make improvements, and in our marketing efforts. Some of these cookies involve tracking of users as they move through or between websites and the gathering of information in order to personalise content and advertising. Where such cookies involve the processing of your personal information, this is covered by our Privacy Policy.

What are cookies?

Cookies are small data files that are placed on your computer or mobile device when you visit a website. Cookies set by the website owner or service provider (in this case, Big Clean Switch) are called “first-party cookies”. Cookies set by parties other than the website owner are called “third-party cookies”. Third-party cookies enable third-party features or functionality to be provided on or through the website or service you are using (such as advertising, interactive content and analytics). These third-party cookies enable those third parties to recognise your computer as it visits different websites.

Why do we use cookies and other tracking technologies?

We use first-party and third-party cookies for several reasons.

Essential Cookies

Some cookies are required for technical reasons in order for our website to function properly. We refer to these as “essential” cookies.

Counting Cookies

Some cookies allow us to understand how our website is being used by visitors. These cookies, mostly placed by our analytics provider, Google, differentiate between different visitors and store aggregated data about them to enable us to identify trends or problems in how people use the site.

Advertising Cookies

As with most other businesses, we use advertising to reach out to people we think may be interested in our website. Cookies allow us to identify when people click through from an advertiser, as well as helping us to find people who may be interested in our services (such as someone who may previously have visited our site) when they use other people’s products and services. These advertising cookies then allow those websites and apps to display tailored content.

Cookies served through Big Clean Switch

The specific types of first and third-party cookies served through our Big Clean Switch and the purposes they perform are described in further detail below. It should be noted that third party providers may add, change or stop using cookies from time to time. We make every effort to keep track of these changes and to update this policy accordingly, but if you become aware that any of the information below is out of date, please email us at my.data@bigcleanswitch.org to let us know.
