What are cookies?
Cookies are small pieces of data, stored in text files, that are stored on your computer or other device when websites are loaded in a browser. They are widely used to “remember” you and your preferences, either for a single visit (through a “session cookie”) or for multiple repeat visits (using a “persistent cookie”). They ensure a consistent and efficient experience for visitors, and perform essential functions such as allowing users to register and remain logged in.
Many of the cookies we use are only set if you are a registered WordPress.com user (so you don’t have to log in every time, for example), while others are set whenever you visit irrespective of whether you have an account.
