Privacy policy

Last updated: 16 October 2026

1. Controller

2. Hosting and access data

This website is hosted on Cloudflare Pages, a service of Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA. When you open a page, your browser automatically sends technical data to the server. This includes your IP address, the date and time of the request, the page requested, the referring page as well as the browser and operating system you use.

Cloudflare processes this data on our behalf so that the website can be delivered and protected against attacks and misuse. The legal basis is Art. 6(1)(f) GDPR, our legitimate interest being a secure and reliable website. We have a data processing agreement with Cloudflare. Cloudflare is certified under the EU‑US Data Privacy Framework, which covers transfers of data to the USA. We do not keep our own server log files.

3. No cookies, no tracking

This website does not set cookies and does not use analytics or advertising tools. We do not embed fonts, videos, maps or other content from third parties.

4. Contact by email

If you write to us by email, we process your email address and the content of your message in order to answer you. The legal basis is Art. 6(1)(b) GDPR where your enquiry relates to a contract, and Art. 6(1)(f) GDPR in all other cases. We delete your message once it has been dealt with, unless statutory retention periods apply. Our email service is provided by IONOS SE, Elgendorfer Str. 57, 56410 Montabaur, Germany, under a data processing agreement.

5. Your rights

Under the GDPR you have the right of access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18) and data portability (Art. 20). You may object at any time to processing based on Art. 6(1)(f) GDPR (Art. 21). To exercise your rights, an email to info@czyszltd.de is enough.
