Necessary
Necessary local data remembers the selected theme and language, dismissal of the language suggestion and privacy settings. These preferences would not work correctly without it, so this category cannot be disabled in the panel. Explicit theme and language choices and language-suggestion dismissal remain until site data is cleared; the consent record expires after 12 months.
Analytics
After consent, Matomo uses cookies to recognize visits, measure page views and aggregate interactions. No analytics data is sent before consent.
Managing your choice
You can accept, reject or configure analytics in the privacy panel. Change the choice at any time through “Privacy settings” in the footer. Withdrawal removes accessible Matomo cookies and stops future events.
