Cookie policy
This site uses the minimum number of cookies and similar technologies required to work, and nothing else until you say so. Analytics scripts are not loaded at all before you accept them.
Strictly necessary
rt_consent: stores your cookie choice and the version of the policy you were shown, so you are not asked again on every page. Duration: 6 months. This cookie cannot be refused, because it is what records your refusal.
NEXT_LOCALE: remembers the language you are browsing in. Duration: until you close your browser.
Cloudflare Turnstile, on the contact page only: checks technical signals from your browser to stop automated spam submissions, and may briefly keep the data the check needs in your browser. It is strictly necessary for the security of the form, so it does not ask for consent. Cloudflare does not use this data for advertising.
Analytics (only with your consent)
PostHog, with the data stored on PostHog EU Cloud in Frankfurt, Germany, shows us which pages are visited and how quickly they load.
ph_phc_…_posthog: a random identifier that tells one visit from another. Kept as a cookie and in localStorage. Duration: 12 months.
PostHog session data in sessionStorage, starting with ph_: links the pages viewed in the same session. Duration: until you close the tab.
__ph_opt_in_out_phc_…: records in localStorage that you accepted analytics. Duration: until you change your choice.
If you decline, the PostHog script is never loaded and none of this data is created.
Changing your mind
You can change or withdraw your choice at any time using the cookie settings link in the footer. When you withdraw consent, we stop analytics and delete all of the PostHog cookies and data above from your browser.
You can also delete cookies through your browser settings.
