Cookies
There are two types of Cookie:
Session Cookie
Session Cookies are temporary. They allow OD to link the actions of a user during a browser session. A browser session starts when a user opens the browser window and finishes when they close the browser window. Once you close the browser, all session cookies are deleted.
Persistent Cookie
These cookies are set on your first visit to the OD website. They last longer than the duration of your stay and are used to help us understand which parts of our sites are regularly visited and how we can improve the service we deliver.
Functions
Cookies also have, broadly speaking, four different functions and can be categorised as follow: ‘strictly necessary’ cookies, ‘performance’ cookies, ‘functionality’ cookies and ‘targeting’ or ‘advertising’ cookies. OD will use the term ‘Targeting’ when describing this function.
Strictly Necessary
Strictly Necessary cookies are essential to navigate around the OD website and use its features. Without them, you wouldn’t be able to use basic services like registration or the shopping basket. These cookies do not gather information about you that could be used for marketing or remembering where you’ve been on the internet.
Performance
Performance cookies collect data for statistical purposes on how visitors our visitors navigate the OD website; they don’t contain personal information such as names and email addresses and are used to improve your user experience of our website.
Functionality
Functional cookies allow our visitors to customise how our website looks for them: they can remember usernames, language preferences and regions. On other websites they can be used to provide more personal services like local weather reports and traffic news.
Targeting
Targeting cookies are used to deliver advertisements more relevant to you but can also limit the number of times you see an advertisement and be used to chart the effectiveness of an ad campaign by tracking users’ clicks. They can also provide security in transactions.
