Liability and copyright
1. Liability
I am liable for my own content under general law. The provider of a linked third-party page is responsible for its content. If I learn that a linked page breaks the law, I will remove the link without delay.
2. Copyright
The content and works I have created on this website are protected by German copyright law. Any reproduction, adaptation, distribution or other use beyond the limits of copyright law requires my prior written consent. Quoting with attribution is permitted within the limits of the law (§ 51 of the German Copyright Act, UrhG). I mark third-party content as such and respect its copyright. Should you nevertheless become aware of a copyright infringement, please let me know. If I become aware of any legal violations, I will remove such content without delay.

Privacy
This site sets no cookies, uses no analytics, and loads no fonts, images or scripts from other domains unless you start a video. I am the controller of your data, at the address and contact details above.
1. Hosting and delivery
The site is hosted on GitLab Pages (GitLab Inc., USA) and delivered through Cloudflare's content delivery network (Cloudflare, Inc., USA). When you open a page, both providers process technical access data, such as your IP address, the page requested and the time. Without your IP address, the page cannot be sent to your browser. The purpose is to deliver the site reliably and fend off attacks. The legal basis is my legitimate interest in doing so (Art. 6(1)(f) GDPR).
I run no server of my own and keep no access logs of my own. GitLab states that it keeps GitLab Pages access logs for seven days. Cloudflare does not specify a fixed period; under its privacy policy, retention depends on the purpose and on legal obligations.
If a page fails to load, your browser may send an error report to Cloudflare (Network Error Logging). For this, your browser stores an instruction from Cloudflare for seven days saying where such reports go. Cloudflare states that it does not store the IP address with these reports. The legal basis is my legitimate interest in a reliably reachable site (Art. 6(1)(f) GDPR). The instruction in your browser is part of delivering the page you requested (§ 25 (2) no. 2 TDDDG, the German telecommunications and digital services data protection act).
2. Video
The video on the home page only loads when you click it. Your browser then fetches it from youtube-nocookie.com, a Google service (Google Ireland Limited, Ireland, and Google LLC, USA). Google receives your IP address and technical details of your browser, and YouTube may store data in your browser. The preview says that the video loads from YouTube. The legal basis is the consent you give by clicking (Art. 6(1)(a) GDPR, § 25 (1) TDDDG). It covers that one playback, and you can withdraw it at any time with effect for the future: without a new click, nothing loads from Google. You can delete what YouTube stored in your browser by clearing the site data for youtube-nocookie.com. What Google does with the data is set out in Google's privacy policy.
3. Email
If you write to me, I process the data in your message to reply (Art. 6(1)(f) GDPR) and delete it once I no longer need it for that. My mailbox is run by Google (Google Workspace).
4. Transfers to the USA
GitLab, Cloudflare and Google also process data in the USA. GitLab Inc., Cloudflare, Inc. and Google LLC state that they participate in the EU-U.S. Data Privacy Framework. For participating companies, the European Commission's adequacy decision applies (Art. 45 GDPR).
5. Your rights
You have the right of access, rectification, erasure and restriction of processing (Art. 15 to 18 GDPR) and, where the conditions are met, to data portability (Art. 20 GDPR). An email to the address above is enough. You may also lodge a complaint with a data protection supervisory authority (Art. 77 GDPR). The authority responsible for me is the Hamburg Commissioner for Data Protection and Freedom of Information (Hamburgische Beauftragte für Datenschutz und Informationsfreiheit), Ludwig-Erhard-Straße 22, 20459 Hamburg, Germany.
Objection: You may object at any time, on grounds relating to your particular situation, to processing based on my legitimate interest (Art. 21 GDPR).
You do not have to give me any data. Without the access data the page cannot be shown, and without contact details I cannot reply. There is no automated decision-making or profiling here.
