1. What cookies are
Cookies are small text files stored by a website in your browser or device. They help retain necessary states, improve browsing and understand how pages are used.
2. Cookie categories
Necessary cookies support operation, security, language selection and sessions, and generally cannot be disabled through site functions. Preference cookies remember language or interface settings. Analytics cookies measure visits, sources and overall browsing trends to improve content and structure, generally using aggregated results.
3. Third parties and duration
Analytics, online consultation and other technical providers may set their own cookies or collect necessary device and log data under their own rules. Session cookies normally expire when the browser closes; persistent cookies remain for their configured period unless deleted. Cookies alone do not require unrelated sensitive details such as bank cards, identity document numbers or passwords.
4. Your choices and contact
