A cookie is a file containing an identifier (a string of letters and numbers) that is sent by a web server to a web browser and is stored by the browser. The identifier is then sent back to the server each time the browser requests a page from the server.
Cookies may be either "persistent" cookies or "session" cookies: a persistent cookie will be stored by a web browser and will remain valid until its set expiry date, unless deleted by the user before the expiry date; a session cookie, on the other hand, will expire at the end of the user session, when the web browser is closed.
Cookies do not typically contain any information that personally identifies a user, but personal information that we store about you may be linked to the information stored in and obtained from cookies.
Cookies can be used by web servers to identify and track users as they navigate different pages on a website and identify users returning to a website.
We use both session and persistent cookies on our website.
There are two types of cookies that we use on our website:
(a) Necessary: These cookies are essential to the operation of the site such as tracking the steps the user has taken in a survey before it is submitted; staying logged into the site once authenticated; maintain a chat session within the user’s browser
(b) Personalization: Cookies designed to give the user a personalized browsing experience. For example, a user can choose to hide guidance (help screens) during data completion on a survey; a cookie is used to persist the user's preference to hide or show this whenever loading a page; track the progress of a download so that the UI can respond once the download is complete
