This private, non-commercial website processes as little personal data as possible.
This website is hosted by GitHub, Inc. / GitHub International Limited via the "GitHub Pages" service. When you visit the website, GitHub as the hosting provider automatically processes technically necessary server log files transmitted by your browser: IP address, date and time of the request, page requested, referrer URL, browser type and operating system. This processing is technically required to provide the website (legal basis: Art. 6(1)(f) GDPR, legitimate interest in secure and functional operation). Details on GitHub's data processing are available in the GitHub Privacy Statement.
GitHub, Inc. is based in the USA. For transfers of personal data to the USA, GitHub states that it relies on the EU-U.S. Data Privacy Framework (DPF) and its UK and Swiss extensions (checked July 2026 — the site owner should periodically re-verify this).
This website does not set its own tracking cookies. Your browser's local storage (localStorage) holds only technically necessary values: your chosen language, your chosen theme (light/dark), and your cookie consent status. This data never leaves your device and is not transmitted to anyone. Under German law (§ 25(2) No. 2 TDDDG, the Telecommunications-Digital-Services-Data-Protection Act), this technically necessary storage does not require separate consent.
This website uses Google Analytics, a web analytics service provided by Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland; parent company Google LLC, USA). Google Analytics loads only after your explicit consent via the cookie banner (legal basis: Art. 6(1)(a) GDPR, § 25(1) TDDDG). Without consent, no data is transmitted to Google whatsoever.
Where consent has been given, the IP address is shortened before processing (IP anonymization, the anonymize_ip parameter). Google Analytics sets its own cookies to recognize repeat visits. For transfers to the USA, Google likewise states that it relies on the EU-U.S. Data Privacy Framework.
You can withdraw your consent at any time via the "Cookie settings" link in the footer; processing will then stop.
The fonts used on this website (Inter, Spectral) are served by this website itself. No connection is made to Google Fonts or any other external font service, and no data is transmitted to third parties for this purpose.
The Leaflet mapping library is served by this website itself. However, when you open the map page, the map tiles are loaded directly from the OpenStreetMap Foundation's servers (tile.openstreetmap.org), which transmits your IP address to the OpenStreetMap Foundation. This is technically necessary to display the map you requested (legal basis: Art. 6(1)(f) GDPR, legitimate interest in providing the requested feature). Information on OpenStreetMap's data processing is available in the OpenStreetMap Foundation Privacy Policy. The map data itself is licensed under the Open Database License (ODbL), © OpenStreetMap contributors.
The contact form on this website only prepares an email in your own email application (a mailto link). The data you enter is never transmitted to or stored on any server of this website — this static site has no server-side processing of form data at all. Only once you actually send the prepared email from your own email application is your information transmitted to the site owner's email address; that transmission is subject to your own email provider's terms.
This website does not embed any payment widgets. The PayPal, Ko-fi and ЮMoney (YooMoney) buttons are plain links that take you to the respective external website. Only if you take action there do these providers process your data, under their own privacy policies: PayPal, Ko-fi, ЮMoney. Support given through these services is a voluntary private contribution to the site owner, not a tax-deductible donation, as this project does not hold a corresponding official non-profit status.
Recipients of personal data in connection with this website may include: GitHub, Inc. (hosting, USA/EU), Google Ireland Limited / Google LLC (web analytics, only with consent, USA/EU), and the OpenStreetMap Foundation (map tiles, United Kingdom). No data is transferred to any other recipient, unless you yourself send an email or use a payment service.
GitHub server logs: retention is set by GitHub and should be confirmed by the site owner. Google Analytics data: retention is configured by the site owner in the Google Analytics account settings. Local storage (language, theme, cookie consent): until you clear it in your own browser.
Under the GDPR you have the right to: access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20), and objection to processing (Art. 21). To exercise these rights, contact the email address above or use the "Correction" option in the contact form. You also have the right to lodge a complaint with a data protection supervisory authority, in particular in the EU member state of your habitual residence. The specific German state (Bundesland) authority responsible for the site owner will be added here once the owner's address is confirmed.
Any consent given (e.g. for Google Analytics) can be withdrawn at any time, with effect for the future, via the "Cookie settings" link in the footer of this website.
This website is not specifically directed at children or minors and does not knowingly collect personal data from minors. The historical and genealogical content sometimes mentions people who were minors at the time of the events described; these are exclusively historical, mostly deceased individuals discussed in the context of genealogical history, not an active collection of data about living minors.
This privacy policy may be updated as needed, for example when the website's features or the applicable law change. The version currently published on this page applies. Last updated: 25 July 2026.
