Google Analytics 4

With your permission, this website uses Google Analytics 4 to understand visits and interactions. Measurements may include page views, approximate location derived from IP address, device and browser information, traffic source, scrolling, outbound link clicks, file downloads, form interactions, and inquiry-related actions. We do not intentionally send names, email addresses, telephone numbers, form contents, or other directly identifying information to Google Analytics.

Google may process analytics data on servers in multiple countries. Google acts as an analytics service provider under its applicable data-processing terms. Analytics information is used to improve website content, product navigation, and inquiry journeys.

Cookies and consent

Analytics storage is denied by default. If you select “Accept analytics,” Google Analytics may store or read analytics cookies. If you select “Reject analytics,” analytics storage remains denied. Advertising storage, advertising user data, and ad personalization are disabled. Your choice is stored in your browser and can be reset by clearing this website's local storage or cookies.

For visitors in the European Economic Area, United Kingdom, and Switzerland, consent is requested before analytics storage is enabled. Google Consent Mode communicates the selected privacy choice to the Google tag.

Legal basis, retention, and your rights

We process inquiry information to take steps requested before a business transaction and for legitimate business interests such as responding to customers and maintaining records. Analytics storage is based on consent where required. Data is retained only as long as reasonably necessary for these purposes, legal obligations, dispute resolution, and security.

Depending on your location, you may have rights to request access, correction, deletion, restriction, objection, portability, or withdrawal of consent. Contact us using the email above. You may also lodge a complaint with the relevant data-protection authority.

External services and links

The website may link to email, WhatsApp, downloadable documents, and third-party websites. Those services apply their own privacy policies. We use reasonable technical and organizational safeguards, but no online transmission or storage method is completely secure.
