Cookies are text files that contain small amounts of information and are downloaded to your device when you visit a web page. The cookies are then sent back to the original web page on each subsequent visit (first party cookies) or to another web page that recognizes that cookie (third party cookies). Cookies are useful because they make it possible for a web page to recognize a user's device. Cookies have many purposes, such as allowing you to navigate between pages efficiently, remembering your preferences and, in general, improving your user experience. They also help you ensure that the ads you see online are the most relevant to you and your interests.
Based on the function that cookies have and the purpose for which they are used, there are four categories of cookies: strictly necessary cookies, performance cookies, functionality cookies or advertising cookies.
Strictly necessary cookies
They are essential for you to be able to move around a web page and use its functions. Without these cookies, you will not be able to offer the services you demand, for example, remembering previous actions (such as the text entered) when you return to a page without having logged out.
They collect information about how a web page is used, for example, which pages users go to most often and whether those web pages give them error messages. These cookies do not collect information that identifies the user: all the information that these cookies collect is aggregated and, therefore, anonymous. It is only used to improve the functioning of a web page.
They make it possible for a web page to remember your preferences (such as username, language or your geographical location) and offer you enhanced and personal functions. For example, a website could offer you tax information regarding local prices by using a cookie to save the province in which you are currently located. Functionality cookies can also be used to provide services that you request, such as watching a video. The information collected by these cookies can be kept anonymous and they will not be able to track your browsing activity on other web pages.
They are used to show you the ads that are most relevant to you and your interests. They are also used to limit the number of times you see an ad, as well as to help measure the effectiveness of an ad campaign. They remember whether you have visited a web page or not, and this information is shared with other organizations, such as advertisers. Advertising cookies will often be linked to the functionality of a site from other organizations.
Cookies will be set by our website (first-party cookies) or by other websites that run their content on our website (third-party cookies); for example, our web pages include embedded "Share" buttons that allow web users to share their content with friends through social networks such as Facebook and Twitter. Those other pages may set a cookie when you are logged into their service. SERES does not control the cookies on these web pages. Check the web pages of third parties for more information about their cookies and how to manage them.
