The National Institute of Chemistry's privacy policy on cookies

Legal basis

The basis for this notice is the amended Electronic Communications Act (Official Journal of the Republic of Slovenia, No. 130/22 and 18/23 - ZDU-1O; hereinafter referred to as ZEKom-2), which entered into force on 10 November 2022. The current legislation does not prohibit the use of cookies, but rather prescribes under what conditions and how cookies and similar technologies may be used.

What are cookies?

Cookies are small files, usually containing a sequence of letters and numbers, which are downloaded to a user's computer or mobile device (hereinafter referred to as the device) when the user visits a particular website and usually contain:

  • the name of the server from which the cookie was sent;
  • the lifetime of the cookie;
  • value - usually a randomly generated unique number.

Each time you visit the website again, it will retrieve the cookie you have placed and identify your device. On each return visit, the website will retrieve the cookie information and identify the user.

Cookies are important for the functioning of websites to make the user experience better. They can be used to analyse website traffic and enable advanced advertising techniques. At the same time, cookies can be used to track a specific user through different websites and to create a profile of that user, which can reveal private details of their life.

The National Institute of Chemistry stores cookies on the user's device when they are strictly necessary for the operation of this website. For all other types of cookies we need your permission. This site uses different types of cookies.

The Institute's website is hosted on its own server infrastructure, with system maintenance of the web server managed by a contractor based in Slovenia.

Types of cookies:

  • Temporary or session cookies "live" from the moment the user opens the browser until the moment the user ends the session and closes the browser. They are used by websites to store temporary information, for example items in a shopping cart, to make online banking more secure, etc. Because such cookies are stored for a shorter period of time, they can be less invasive to a user's privacy.
  • Persistent cookies remain stored even after the user closes the browser and ends the session. They are used by websites, for example, to store information about registration, page language settings, etc., as well as to build user profiles and analyse traffic. Persistent cookies can remain on your computer for days, months or even years.
  • First party cookies are from the website that the user is viewing and can be permanent or temporary. Websites use these cookies to store information that will be used again the next time the user visits the site.
  • Other cookies (3rd party cookies) come from other, partner websites (which, for example, serve ads on the original website or measure traffic). Third parties may collect user data from different websites in this way and use it for different purposes: from advertising, analytics to improving their products. Such cookies represent a greater intrusion on user privacy.

Cookies may also be used to collect anonymised statistics about users' online navigation experiences on our websites.

Why are cookies necessary?

Cookies are important for the operation of websites and are fundamental to providing user-friendly online services that improve the user experience. The most common ecommerce functions would not be possible without cookies.

Why do websites use cookies?

Websites work optimally when cookies are enabled. Most websites use cookies for a variety of purposes:

  • adjust the display of content to visitors based on past visits, to improve the user experience of the website;
  • to store choices when shortlisting and comparing devices and offers;
  • keep users logged in on the parts of the website where login is required;
  • to recognise the user's device (computer, tablet, mobile device), allowing the content to be tailored to the user's device;
  • to collect various statistics about the habits of web users - as these are the only way to monitor how often they visit a particular website;
  • to monitor traffic, which allows us to detect and correct errors, check the effectiveness of content display and the relevance of advertisements, and continuously improve our websites;
  • they are necessary for certain services to work (e.g. online banking, online shops and other forms of e-commerce...).
