What is a cookie
A cookie is a small amount of data which often includes a unique identifier that is sent to your computer or mobile phone (referred to here as a “device”) browser from a website’s computer and is stored on your device’s hard drive. Each website can send its own cookies to your browser if your browser’s preferences allow it, but your browser only permits a website to access the cookies it has already sent to you, not the cookies sent to you by other websites.
Which cookies does DCI use
DCI uses both session ID and persistent cookies to track your viewing of our websites. A session cookie expires as soon as you leave the website, while a persistent cookie stays on your computer across multiple visits to the site. Information supplied by cookies can help us to analyse the profile of our visitors and help us to provide you with a better user experience.
We collect information about your use of the websites, via cookies sent by us and third-party partners, to help us improve the sites. The following types of cookies are used on our websites:
- Strictly necessary/essential cookies These cookies are essential to enable you to move around the websites and use its features. Without these cookies, services you have asked for cannot be provided. These cookies don’t collect information that identifies a visitor.
- Performance cookies These cookies collect information about how visitors use a website, for instance which pages visitors go to most often, and if they get error messages from websites. These cookies don’t collect information that identifies a visitor. All information these cookies collect is aggregated and therefore anonymous. It is only used to improve how a website works.
- Functionality cookies These cookies allow the websites to remember choices you make (such as your name, language or the region you are in) and provide enhanced, more personal features. For instance, a website may be able to pre-fill form fields based on a previous visit by storing a profile ID in a cookie that can be queried later. They also remember preference choices such as whether to show the cookie notice or not and similar actions taken. The information these cookies collect may be anonymized and they cannot track your browsing activity on other websites.
