What are the different types of cookies stored on my device?
- These cookies are commonly used by online shops and allow, for example, the website to remember what items you added to your shopping card. Consequently, if you open the same website in a new tab or window, your items will still be stored in your shopping card.
These cookies will expire as soon as the web browser is closed.
- These cookies are primarily used by websites that feature a registration/log-in for its users. These cookies allow the website to remember you, so it will not require your password each time you open it in a new window, or open it again after a few days or a few weeks even. The law regarding permanent cookies stipulates that they have to be deleted after a period of 6 months.
- These cookies are installed by third-parties with the aim of collecting information. This information is used to carry out research into behavior or demographics, for instance. A good example of third-party cookies are the ones used by the Google Analytics platform.
