No cookies, no third-party requests
This website sets no cookies and loads nothing from third-party servers: fonts, logos, images and the statistics script are served from the same host as the page itself. There is no content delivery network, no embedded maps, videos or social media buttons. Your browser establishes no connection to any third party while visiting this site.
There is no automated decision-making, including profiling, within the meaning of Art. 22 GDPR.
Visitor statistics
We count visits to this website with Umami, open-source software running on our own servers in Germany. Your browser loads a small script from klackwerk.de and reports for each page view: the page requested, the previously visited page (referrer) if your browser sends it, browser type, operating system, device type, screen size, language setting, and the country and region derived from the IP address.
The IP address itself is not stored. To group the page views of one visitor within a day, Umami derives a hash from the IP address, the browser identification and a random value that changes daily; once the day is over, the hash can no longer be linked to anyone. No cookies are set and no identifier is stored in your browser. If your browser sends the “Do Not Track” setting, the visit is not counted.
Purpose: learning which pages are read and where visitors come from, in order to improve the content and technology of the website.
Legal basis: Art. 6(1)(f) GDPR. Our legitimate interest lies in audience measurement without cookies and without disclosure to third parties.
Retention: the statistics no longer relate to an identifiable person and are kept indefinitely.
Server log files
Each page request transmits technically necessary data that our web server records:
- IP address of the requesting device
- date and time of the request
- the requested address, the status code and the volume of data transferred
- the previously visited page (referrer), if your browser sends it
- browser type, browser version and operating system
Purpose: delivering the page, operational security, and detecting and investigating faults and attacks.
Legal basis: Art. 6(1)(f) GDPR. Our legitimate interest is the secure, stable operation of this website.
Retention: the logs are not combined with other data sources and are not used to analyse user behaviour. They are deleted after 90 days at the latest.
Contacting us by email
If you write to us, we process the details in your message (name, email address and content) in order to answer your enquiry.
Legal basis: Art. 6(1)(b) GDPR where your enquiry concerns a contract or its preparation; otherwise Art. 6(1)(f) GDPR, our legitimate interest in responding to enquiries.
Retention: until your enquiry has been dealt with conclusively. After that we delete it, unless commercial or tax law requires us to keep it (§ 257 German Commercial Code, § 147 German Fiscal Code: six and ten years respectively).
Contact form
The form on the contact page transmits your input (name, optionally company, email address and message) encrypted to our own server. There it is turned into an email to contact@klackwerk.de and delivered through our own mail server; no third party is involved. To fend off automated submissions the server checks a field invisible to people, the time taken to fill in the form and the number of requests per IP address within an hour. The IP address is kept in memory for that hour only and is not written into the email. The input itself is not stored on the server; it exists only in the email, to which the section “Contacting us by email” above applies.
Hosting
This website is operated as a static site by a processor. Operation takes place exclusively within the European Union; a data processing agreement under Art. 28 GDPR is in place with the provider. No personal data is transferred to a third country.
Provider: Hetzner Online GmbH, Industriestr. 25, 91710 Gunzenhausen, Germany
