What this site stores in your browser, what needs your consent, and how to change your choice. Last updated: September 2026.
What is stored in your browser
Analytics and advertising cookies are set only after you allow them in the banner. Until then Google’s tag is not loaded at all.
- mq_consent — necessary
- Our own cookie. Remembers your choice in the banner, so it is not asked on every page. 180 days.
- _ga, _ga_* — Analytics
- Google Analytics 4. Distinguishes visits and sessions. Up to 2 years. Only with consent.
- _gcl_au, _gcl_aw — Advertising
- Google Ads. Link an enquiry to the ad click that brought you here. 90 days. Only with consent. Not used for remarketing.
- __ddg1_, __ddg8_–__ddg10_ (DDoS-Guard) — necessary
- The protection service in front of this site sets technical cookies to distinguish visitors from automated traffic. They carry no marketing data. __ddg1_ is kept for up to 1 year, __ddg8_–__ddg10_ for 20 minutes; __ddg9_ contains your IP address.
- Fonts
- Served from our own server. Nothing is requested from Google Fonts.
- Video and maps
- Embedded video and maps load only after you click. Until then no request goes to the external service and no cookie is set.
Changing your choice
Open Cookie settings at the bottom of any page. You can allow or refuse analytics and advertising separately. If you withdraw consent, the Google cookies are deleted and the tag stops loading.
Refusing does not limit the site: every page and the enquiry form work the same either way.
- “Accept all” and “Reject all” are equally easy
- Nothing is sent to Google before you choose
- Your choice is kept for 180 days, then asked again
- Blocking cookies in your browser does not break the site
