Privacy Policy

Draft for the website preview: Before the public launch, hosting and the contractual chain, data processing arrangements, server location, actual logging and retention periods, the email provider and any international transfers must be confirmed.

1. Controller

The controller for this website is Knopf Construction Management GmbH, Jägerhofstraße 20, 40479 Düsseldorf, Germany, represented by its managing director Peter Knopf. Contact for data protection enquiries: Paulo J. De Souza. Email: kontakt@knopf-construction.org Responsibility for processing personal data remains with Knopf Construction Management GmbH.

2. Overview

This website is deliberately lean: we use no cookies, no external analytics or tracking tools, no social media plugins and no advertising. Fonts and all other content are delivered from our own server; visiting the site does not open any connection to third parties. There is no contact form. Project videos are also delivered from our own server. Public visitor counter: We display an estimated total number of visits since 4 November 2026. An identifier is calculated from the IP address and browser identifier using a random secret that changes daily. It is held temporarily in server memory only. The counter does not save the IP address or browser identifier. Identifiers are discarded daily and on server restart; only the aggregate total and start date are saved. No cookies, local browser storage or external analytics services are used. The same browser on the same network is counted at most once per day. Shared networks, different devices or server restarts may affect the estimate.

3. Hosting

The hosting provider, contractual chain, data processing agreement, server location and any international transfers will be confirmed with the operator and specified before the public launch.

4. Server log files

Each time the website is accessed, our web server automatically processes data transmitted by your browser: IP address, date and time of access, page or file requested, amount of data transferred, status code, the previously visited page (referrer), and browser type and operating system. The purpose is to provide the website securely and reliably, in particular to prevent and investigate attacks and faults. The legal basis is Art. 6(1)(f) GDPR; our legitimate interest lies in these purposes. The configured retention period for server log files will be verified and specified here before the public launch. The data is not combined with other data or analysed for advertising or profiling.

5. Contact by email

If you email us, we process the information you provide (in particular your name, email address and the content of your message) in order to answer your enquiry. The legal basis is Art. 6(1)(b) GDPR where your enquiry relates to a contract or pre-contractual steps, and otherwise Art. 6(1)(f) GDPR (our legitimate interest in answering enquiries). Your data is deleted once the enquiry has been dealt with, unless statutory retention obligations (e.g. under commercial and tax law for business correspondence) apply.

6. Encryption

The website is delivered exclusively over an encrypted connection (HTTPS/TLS), so that data you transmit to us cannot be read by third parties.

7. Your rights

Subject to the statutory requirements, you have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18) and data portability (Art. 20). You may withdraw any consent you have given at any time with effect for the future. You also have the right to lodge a complaint with a data protection supervisory authority (Art. 77 GDPR). The authority responsible for us is the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia (LDI NRW), Kavalleriestraße 2–4, 40213 Düsseldorf, Germany. To exercise your rights, simply send an email to kontakt@knopf-construction.org.

8. Right to object (Art. 21 GDPR)

Where we process data on the basis of Art. 6(1)(f) GDPR, you have the right to object to this processing at any time on grounds relating to your particular situation. We will then no longer process the data unless we can demonstrate compelling legitimate grounds that override your interests, rights and freedoms, or the processing serves to establish, exercise or defend legal claims. No particular form is required; an email to kontakt@knopf-construction.org is sufficient.

9. No automated decisions; updates

No automated decision-making, including profiling within the meaning of Art. 22 GDPR, takes place. You are not legally or contractually required to provide personal data; the website can be used without providing any information. We will update this privacy policy if the website or the legal situation changes. Last updated: October 2026.
