Privacy policy

Last updated: October 2026

We take the protection of your personal data seriously. We process personal data in accordance with the Swiss Federal Act on Data Protection (FADP) and — where applicable — the EU General Data Protection Regulation (GDPR). Below we inform you about the nature, scope and purpose of the processing in connection with this website.

1Responsible party

2Processing when you visit the website

When you access our website, the hosting provider automatically records technical data in server log files (e.g. IP address, date and time of access, page requested, browser and operating system used). This data is used solely to ensure the secure and stable operation of the website and is not combined with other data sources. The website is delivered via the network of Cloudflare, Inc. (101 Townsend St, San Francisco, CA 94107, USA). Data may therefore also be processed outside Switzerland; Cloudflare is certified under the Swiss-U.S. Data Privacy Framework.

3Contact by e-mail or telephone

When you contact us by e-mail or telephone, we process your details (e.g. name, e-mail address, telephone number, content of your enquiry) solely to handle your request. We retain the correspondence for as long as necessary to process it or as required by statutory retention obligations.

4Cookies and tracking

This website does not set any cookies and does not use any analytics or tracking services. Your usage behaviour is not evaluated.

5Fonts and maps

For consistent display, the “Inter” font is embedded via Google Fonts (Google Ireland Limited or Google LLC). When the font files are loaded, your IP address is transmitted to Google. Further information can be found in Google's privacy policy.

The “Properties” page embeds an interactive map (Leaflet map library via unpkg.com, map tiles by Esri). When the map loads, your IP address is transmitted to these providers.

6Data security

The website is delivered in encrypted form via HTTPS (TLS) to protect the transmission of your data. We take appropriate technical and organisational measures to protect your data against unauthorised access, loss or misuse.

7Your rights

Within the scope of applicable data protection law, you have the right to information about the data processed concerning you, as well as the right to rectification, erasure or restriction of processing. To exercise your rights, a notification to the responsible party named above is sufficient. You also have the right to lodge a complaint with the Federal Data Protection and Information Commissioner (FDPIC).

8Changes

We reserve the right to amend this privacy policy at any time in order to adapt it to changed legal requirements or changes to our website. The version currently published on this website applies.
