Automated Decision-Making and Profiling

Website visitors: We do not carry out automated decision-making or profiling of website visitors that produces legal effects or significantly affects individuals (Art. 22 GDPR).

Analytics - Matomo (self-hosted): The website supports optional measurement with our self-hosted Matomo service on Hostinger infrastructure. Collection is currently inactive.

Configuration: The website integration applies these controls before optional collection can operate:

  • No cookies are set.
  • No requests are sent to a collector until an approved collector is configured and analytics consent is given.
  • Cookieless measurement may still use technical signals to associate activity. It is not treated as exempt from consent.
  • The DoNotTrack signal sent by your browser is respected; visits with DoNotTrack enabled are not recorded.

Data collected: Canonical page paths, page titles, language, technical browser information and nonpersonal interaction events. Form contents, contact details and URL query strings are excluded. With analytics consent, registered campaign codes and the canonical page context may accompany an enquiry. Campaign context is retained in this browser for up to 30 days and removed when analytics consent is withdrawn.

Legal basis: Optional analytics is based on your consent under Art. 6(1)(a) GDPR and, where applicable, section 25(1) TDDDG. No analytics requests are made before permission.

Retention: No Matomo visit data is currently collected by this website. The retention period will be stated here before collection is activated.

Withdrawal of consent: Use Cookie Settings and select Necessary only to stop future optional collection. Enquiries remain available. Exclude me from Matomo tracking (This sets a "do not track" flag in your browser's local storage. It remains in effect until you clear browser data.)

AI services: Zirkel Technologies GmbH provides AI and machine learning services to business clients. Any automated processing forming part of client-specific solutions is governed by the data processing terms agreed with those clients and does not affect visitors to this website.
