3. Analytics

We use PostHog, hosted in the European Union (Frankfurt), to understand how the site is used. PostHog cookies and storage are set only after you accept the “Measurement” category in the cookie banner. If you do not accept, no analytics identifier is stored and no analytics request leaves your browser.

4. Managing Your Preferences

You can change or withdraw your consent at any time by clicking “Manage cookie preferences” in the footer of every page. You can also delete cookies through your browser settings.
