What are cookies
Cookies are small text files stored on your device when you browse a website. They can be used for technical operation, preference management, analytics, and marketing activities.
Cookie categories used on this website
- Necessary cookies: required for essential website operation and security. These cookies are always active.
- Functional cookies: store usability preferences (for example, saved interface choices).
- Analytics cookies: collect aggregated statistics to help us understand traffic and improve the site, if consent-based analytics technologies are activated.
- Marketing cookies: support campaign effectiveness and message relevance.
Legal basis
Necessary cookies are processed on the basis of legitimate interest in providing a secure and functioning service. Functional, analytics, and marketing cookies are activated only with your consent.
Cookies and technologies currently managed
- qv_cookie_consent (cookie): stores your consent preferences.
- qv_cookie_consent_v1 (local storage): stores the same preferences in the browser.
Additional third-party technologies may be activated only according to the consent option you choose.
First-party aggregate analytics without cookies
The website also uses a lightweight first-party analytics system that does not set cookies and does not create persistent visitor profiles. It records pageviews, page path, referrer host, UTM campaign parameters, language, device class, and approximate timezone to produce aggregate weekly reports on website performance.
IP addresses and full user agents are not stored in analytics reports. A daily technical hash may be generated server-side only to estimate unique daily visitors and reduce abuse; it is not used to identify or follow users over time.
Retention period
Consent preferences are retained for 180 days, after which the banner may be shown again to refresh your choice.
Raw first-party analytics event files are retained for up to 180 days unless a shorter period is configured on the server.
Manage or withdraw consent
You can update your cookie preferences at any time by opening the cookie settings panel.
