Information about cookies and similar technologies
1. What Are Cookies
Cookies are small text files stored in your browser when you visit a website. They are used to ensure the proper functioning of the website, to remember your preferences and, in some cases, to analyse traffic.
Cookies themselves do not identify a specific individual, but in combination with other data they may be considered personal data within the meaning of Regulation (EU) 2016/679 (GDPR).
2. Legal Basis
The use of cookies is governed by:
- Act No. 127/2005 Coll., on electronic communications (implementation of the ePrivacy Directive 2002/58/EC)
- Regulation (EU) 2016/679 (GDPR) — where cookies process personal data
- Act No. 110/2019 Coll., on the processing of personal data
Necessary cookies do not require consent — they are essential for the website to function. We store analytical and marketing cookies only with your explicit consent.
3. Cookie Categories
3.1. Necessary (Technical) Cookies
These ensure the basic functionality of the website. The website cannot function properly without them. They do not require consent.
