Privacy policy
Which data this website processes, why, for how long – and what rights you have.
1. Controller
"Katena" Stahlgelenkketten Handelsgesellschaft m.b.H., Jedlersdorfer Platz 7, 1210 Vienna, Austria · Phone +43 1 292 10 71 · Email office@katena.at
Protecting your personal data is important to us. We process your data exclusively on the basis of the statutory provisions (GDPR, Austrian Data Protection Act, Austrian Telecommunications Act 2021). This website works without analytics or advertising tracking unless you expressly consent.
2. Visiting the website (server log files)
When you visit this website, our web host processes technically necessary data (IP address, date and time, requested address, browser type, referrer) in order to deliver the site and keep it secure. The legal basis is our legitimate interest in secure operation (Art. 6(1)(f) GDPR). Log data are deleted automatically at regular intervals unless they are required to investigate a security incident. Fonts and all images are loaded from our own server – no data are transmitted to Google or other providers.
3. Inquiry form and contact by email or phone
If you contact us via the inquiry form, by email or by phone, we process the data you provide (e.g. company, name, email address, phone number, details of your application and optionally uploaded photos or drawings) to handle your inquiry and any follow-up questions. The form data are sent to us by email and additionally stored in a database on our web server so that no inquiry gets lost.
The data are required to take pre-contractual steps or to perform a contract (Art. 6(1)(b) GDPR). They are not passed on to third parties, except to transport and shipping companies for delivery, to our tax advisor to meet tax obligations and to authorities within the legal framework. If no contract is concluded, we delete your inquiry after three years at the latest; if a contract is concluded, the statutory retention periods apply (generally seven years, § 132 Austrian Federal Fiscal Code).
The form uses no external spam protection and sets no cookies.
4. Newsletter
If you subscribe to the newsletter, we store your email address and the time of subscription and confirmation. Subscription uses the double opt-in procedure: you are only subscribed after clicking the confirmation link in our email. The legal basis is your consent (Art. 6(1)(a) GDPR, § 174 Austrian Telecommunications Act 2021). You can withdraw your consent at any time with effect for the future – via the unsubscribe link in every newsletter or an informal message to office@katena.at. After withdrawal we remove your address from the list.
5. Cookies and consent
Without your consent this website sets no cookies for analytics or advertising purposes. The language is selected via the page address and requires no cookie. We only store your decision in the consent dialog (cookie “katena_consent”, 180 days) so that we do not have to ask you on every visit (§ 165(3) Austrian Telecommunications Act 2021, Art. 6(1)(c) GDPR). Consent is managed with the open-source software Klaro!, which is loaded entirely from our own server.
6. Interactive map (OpenStreetMap)
On the contact page we show a locally stored directions map by default. Only if you actively consent do we additionally load an interactive map from the OpenStreetMap Foundation (St John’s Innovation Centre, Cowley Road, Cambridge, CB4 0WS, United Kingdom). Your IP address is transmitted to the OpenStreetMap Foundation in the process. An adequacy decision of the EU Commission exists for the United Kingdom. The legal basis is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time in the cookie settings.
7. Your rights
You generally have the right to access, rectification, erasure, restriction of processing, data portability, withdrawal of consent and objection. Please contact office@katena.at. If you believe that the processing of your data violates data protection law, you can lodge a complaint with the supervisory authority – in Austria the Datenschutzbehörde, Barichgasse 40–42, 1030 Vienna, www.dsb.gv.at.
