Cookie Policy
Last updated: September 2026
This website does not use traditional third-party tracking cookies. It does use browser local storage — covered by the same consent rules as cookies under the German Telecommunications-Digital-Services-Data-Protection Act (TTDSG) and the EU ePrivacy Directive. This page explains exactly what is stored, why, and how you can control it.
What we store

ts_lang |
Necessary | Remembers your chosen language (English or German) so the site opens in the right one next time. | Until you clear your browser storage. |

_ga_<container-id> |
Analytics | Google Analytics — persists session state for the measurement above. | Up to 2 years, or until you switch this category off. |
This site uses Google Analytics (GA4) to understand how visitors use it, but only after you actively opt in via the banner or the preferences below — it stays off by default and for anyone who doesn't opt in. We do not use any advertising or other third-party tracking cookies.
Legal basis
- Necessary storage is permitted without consent under § 25(2) TTDSG, as it is strictly required to operate the site and remember your preference.
- Functional storage is only set after you actively opt in, on the basis of your consent (§ 25(1) TTDSG, Art. 6(1)(a) GDPR). You can withdraw this consent at any time with future effect.
- Analytics storage (Google Analytics) is likewise only set after you actively opt in, on the basis of your consent (§ 25(1) TTDSG, Art. 6(1)(a) GDPR). You can withdraw this consent at any time with future effect, and Google Analytics will stop running from that point on.
Managing your preferences
You can change your choice at any time using the Cookie Settings link in the footer of any page on this site. You can also clear or block local storage entirely through your browser's own privacy settings — note that doing so will also remove your saved consent choice, so you may be asked again on your next visit.
