What are cookies?
We use something known as a "session id" for some functions on www.sj.se and mobil.sj.se, such as for the shopping process. In order to enable this, our server sends your computer a session cookie with a unique ID number each time you visit one of these websites.
Session cookies are used during the time you are active on the website. Without them you could not, for example, go back a step in the shopping process without needing to fill in all of the information again each time. A session cookie is only saved temporarily in your computer's primary storage and is automatically removed when you close your browser.
If you do not want to allow cookies to be used
There is common misconception that cookies are a sort of virus and that with the help of cookies, websites can find out personal information from your computer, or that cookies exist to make it possible to send spam. None of this is true – cookies are simply data.
Most browsers default to allow storage of cookies. If you do not want to accept cookies, you can either set your browser so that you receive a warning each time a website wants to place a cookie on your computer or you can completely disable storage of cookies. You can find information about how to do this in your browser's help function. If you choose to disallow cookies, SJ's websites will not work as well as you, as a user, expect.
