What is cookies?

Cookies are small text files that are stored on your computer or mobile device when you visit a Web site. They are commonly used to make websites work more efficiently, as well as to provide information to website owners. For example, cookies allow a website to remember that you are logged in, what products you have in your shopping cart or your preferred settings such as language and font size.

Why are cookies used?

Cookies perform several functions:

1. Session Cookies: These are temporary cookies that exist only during a browser session. They are deleted as soon as the user closes the browser. They allow users to navigate websites and use the basic functions of a website.
2. Persistent cookies: These cookies remain on the user's device, even after closing the browser, until a set expiration date. They are used to remember user preferences or collect behavioral information.
3. Tracking cookies: These cookies track the user's behavior on the website to build a profile. They can be used for targeted advertising campaigns based on the user's browsing behavior.

The use of cookies makes interaction between users and Web sites faster and easier. Without cookies, a website would not be able to remind you of your previous activities, such as login information or shopping cart items, which would result in a much less user-friendly experience.

Privacy and cookies

Despite their usefulness, cookies can also raise privacy concerns. Because they store information about users' behavior and preferences, cookies can be used to build an online profile of a user, which can sometimes lead to potentially invasive advertising techniques such as targeted ads.

1. Consent to cookies: Due to privacy concerns, websites in many regions, such as the European Union, must inform users about the use of cookies and seek their consent before placing or reading them.
2. Cookie Policy: Many websites have cookie policies that explain what cookies they use, what they are used for and how to delete or block them.
3. Block cookies: Most modern Web browsers offer settings to manage cookies. Users can usually block all cookies, block all third-party cookies or block cookies from specific websites.

In summary, cookies are essential tools that help Web sites function and improve the user experience. However, they can also raise privacy concerns. It is therefore important for users to be aware of how cookies work and how to manage their privacy settings in relation to the use of cookies.
