3. Your Consent

In accordance with the ePrivacy Directive and applicable guidance, strictly necessary cookies do not require prior consent.

Our analytics tool (Umami) does not use cookies and does not collect personal data — it therefore does not require your prior consent. No cookie consent banner is shown for analytics purposes.

You can update your cookie preferences at any time via the "Manage cookies" link in the footer.
