Privacy policy

1. Controller

2. Website access and server data

When this website is accessed, technically necessary connection data is processed to deliver the requested pages and files to your device. This may include the IP address, date and time, requested address, amount of data transferred, status code, referring page and information about the browser and operating system.

Processing is necessary to provide the website securely, reliably and without errors. The legal basis is Article 6(1)(f) GDPR. Our legitimate interests are technical delivery, IT security and the prevention of misuse. This website’s web server does not keep regular visitor or analytics logs. Upstream hosting and security systems may retain technically necessary logs. These are deleted once no longer required for those purposes, normally within 14 days; data relating to a specific security incident may be retained until the incident has been resolved.

Recipients may include hosting and IT providers acting on our instructions.

3. Contacting us

The contact form does not transmit information to the web server. Activating the button creates a pre-filled message in the email program on your device. We receive the information only after you send that email yourself.

If you contact us by email or telephone, we process the data you provide to respond to your enquiry. Article 6(1)(b) GDPR applies to quotations, contracts and pre-contractual steps. Other business enquiries are processed under Article 6(1)(f) GDPR; our legitimate interest is effective communication with prospective customers, customers and business partners.

Enquiries are deleted after completion unless statutory retention duties or other legitimate grounds require continued storage. Business or tax-relevant correspondence is kept for the period required by law. Recipients may include our email and IT providers and the personnel handling your enquiry.

4. Cookies, local storage and audience measurement

This website does not set cookies, store identifiers in Local Storage or Session Storage, or use analytics, tracking, advertising or profiling services. No automated decision-making takes place.

5. Fonts, catalogs and external content

Fonts, product images, logos, scripts and catalog files are served locally by this website. Loading a page therefore does not connect to Google Fonts or another external content network. Catalogs are processed in the browser and are not sent to an external PDF service.

Links to manufacturers and other external websites connect to the relevant provider only after you open the link. From that point, the external provider’s privacy terms apply.

6. Recipients and transfers

We disclose personal data only when necessary for the purposes stated above, required by law or covered by your consent. Recipients may include hosting, email and IT providers and public authorities acting under legal powers. This website does not initiate transfers to a third country. If you open an external link, that provider may process data under its own terms.

7. Your rights

Subject to the GDPR, you have rights including access, rectification, erasure, restriction of processing and data portability. You may object, on grounds relating to your particular situation, to processing based on Article 6(1)(f) GDPR. To exercise your rights, contact info@center4.eu.

You also have the right to lodge a complaint with a data-protection supervisory authority. The authority responsible for Center4 is in particular:

8. Security and updates

We use appropriate technical and organisational measures to protect personal data against loss, misuse and unauthorised access. When publicly deployed, the website is transmitted over encrypted HTTPS connections.

This notice reflects the website’s technical implementation on 10 September 2026. If analytics, marketing, mapping, video or form-processing services are added later, this notice will be updated before they are activated.
