By default, we don't use any cookies on our website. However, when you use the third-party ReachDeck accessibility plugin, the Local Storage of your web browser is utilised which UK GDPR considers equivalent to cookies.
Local Storage (also referred to as 'localStorage' or 'LocalStorage') is a more modern alternative to cookies that stores data on a user's computer. With localStorage, data does not have to be sent back and forth with every HTTP request - this reduces the overall traffic between the user's device and the web server, and in turn the amount of wasted bandwidth. That data will persist in memory even when the browser is closed or the internet connection has failed. Nevertheless, the user can clear the browser data/cache to erase all localStorage data.
