Privacy policy.

When you visit this website, the hosting provider automatically records information transmitted by your browser (server log files): browser type and version, operating system used, referrer URL, host name of the accessing computer, time of the server request and IP address. This data cannot be attributed to specific persons and serves the technical provision and security of the site. The legal basis is Art. 6 (1) lit. f GDPR (legitimate interest). This website is hosted on servers of Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany; a data processing agreement pursuant to Art. 28 GDPR is in place with the provider.

If you write to us by e-mail, by phone or via the contact form, your details (name, e-mail address, optionally company, phone, location and the content of your message) are stored to process your enquiry and for possible follow-up questions. The contact form is processed on our own system and delivered to us by e-mail; no data is passed on to third parties. The legal basis is Art. 6 (1) lit. b GDPR (initiation of a contract) and lit. f GDPR (legitimate interest in answering enquiries). The data is deleted as soon as your enquiry has been fully dealt with and no statutory retention obligations stand in the way.

The technically necessary functions of this site work without tracking cookies. Your cookie decision is stored locally in your browser (localStorage) so that the notice does not appear on every visit — this information never leaves your device. Only if you consent to analytics (see section 5) are Google Analytics cookies set. You can change your choice at any time via “Cookie settings” in the footer.

This website uses Google Analytics 4, a web analytics service of Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland). We use it to evaluate how the site is used (e.g. content viewed, time spent, anonymised clicks on links and buttons). Google Analytics uses cookies for this; the information generated is transmitted to and stored on Google servers, which may involve a transfer to the USA.

It is used exclusively on the basis of your consent (Art. 6 (1) lit. a GDPR, § 25 (1) TDDDG). Without your consent, Google Analytics and the associated cookies are not loaded. You can withdraw your consent at any time with effect for the future — via “Cookie settings” in the footer. Measurement ID: G-JEWRWJFT5Z. Further information can be found in Google's privacy policy.

Fonts, images, videos and JavaScript are delivered locally from our own server. There is no connection to third-party CDNs (e.g. Google Fonts) and no transmission of your IP address to third parties.

This site links to external services (e.g. lightsignalmedia.group, haufschildt-optik.com, reference websites). When you click on them, the privacy policy of the respective provider applies.

You have the right at any time to access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object (Art. 21 GDPR). Please direct requests to the contact details given above. You also have the right to lodge a complaint with a data protection supervisory authority; the authority responsible for us is the Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen (State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia).

This privacy policy is valid as of September 2026. Further development of the website may make adjustments necessary.
