What are cookies
Cookies are small text files that a website stores in your browser. They are used to make the website work (for example, remembering your language preference) or to measure traffic.
Strictly necessary cookies
These cookies are required for the basic functioning of the website and do not require your consent:
• NEXT_LOCALE — stores your chosen language (validity 1 year).
• authjs.session-token / authjs.csrf-token — client portal login (valid for the duration of the session).
Without these cookies the website will not function correctly.
Analytics cookies (with consent)
If you give consent, we store PostHog cookies for anonymised measurement of website traffic (number of visits, most-visited pages, traffic sources). Data is aggregated and is not used for profiling or advertising.
• ph_phc_* — visit identifier and PostHog SDK state (validity up to 1 year).
• Processor: PostHog Inc., USA — transfer covered by Standard Contractual Clauses.
You may withdraw consent at any time — click the “Manage cookies” link in the footer or delete cookies in your browser.
How to manage consent
When you first visit the website we will show you a cookie banner. There you can accept or decline analytics cookies. We remember your decision via the cookie "qs_consent" (validity 6 months).
You can change your consent at any time — either via the button below or by deleting cookies in your browser.
Third-party cookies
The website does not use advertising cookies, social-network cookies, or third-party trackers beyond the PostHog instance described above.
