What cookies are
Cookies are small files stored in your browser when you visit a website. They are used, for example, to remember your chosen language, keep the site secure and understand how pages are used. Similar technologies, such as the browser's local storage, work in a similar way.
How we use them
- Essential: required for the website to work and to remember your choices. They do not depend on consent and do not identify you for advertising purposes.
- Analytics and performance: show how the website is used (most visited pages, clicks, reading time), always in statistical form. Enabled only if you accept.
- Marketing and third-party content: let us measure campaigns and show partner content, such as the Google Maps map on the contact page. Enabled only if you accept.
