To make this site work properly, we sometimes place small data files called cookies on your device. Most big websites do this too.
What are cookies?
A cookie is a small text file that a website saves on your device when you visit the site. It enables the website to remember your actions and preferences (such as login, language, font size and other display preferences) over a period of time, so you don't have to keep re-entering them whenever you come back to the site or browse from one page to another.
There are four types of cookies we and our service providers may use.
- Strictly necessary cookies. These cookies are essential in order to enable you to move around the website and use its features, such as accessing secure areas of the website. Without these cookies services you have asked for cannot be provided.
- 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 web pages. 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 website to remember choices you make (such as your user name, language or the region you are in) and provide enhanced, more personal features. For instance, a website may be able to provide you with local weather reports or traffic news by storing in a cookie the region in which you are currently located. These cookies can also be used to remember changes you have made to text size, fonts and other parts of web pages that you can customize. They may also be used to provide services you have asked for such as watching a video or commenting on a blog. The information these cookies collect may be anonymized and they cannot track your browsing activity on other websites.
- Advertising cookies. These cookies are used to deliver adverts more relevant to you and your interests. They are also used to limit the number of times you see an advertisement as well as help measure the effectiveness of the advertising campaigns. They are usually placed by advertising networks with the website operator's permission. They remember that you have visited a website and this information is shared with other organizations such as advertisers. Quite often targeting or advertising cookies will be linked to site functionality provided by the other organization.
How long do cookies stay on my device?
These cookies either expire after a browser session or are stored on your device in between browser sessions. The cookies erased when you close your browser are session cookie while persistent cookies will remain on your device for a pre-defined period of time.
