Privacy policy
Last updated: September 21, 2026
1. Controller
The controller responsible for processing personal data in connection with this website is:
PD Dr. med. Fabian von Knoch
Privatklinik Bethanien, Toblerstrasse 51, CH-8044 Zurich
Telephone: +41 43 268 28 13
Email: vonknoch@hin.ch
2. Scope and legal framework
This policy explains how personal data is processed when this website is used. The Swiss Federal Act on Data Protection (FADP) and its ordinance apply. Where applicable in an individual case, the requirements of the EU General Data Protection Regulation are also taken into account.
3. Website access and server logs
When the website is accessed, the server processes technical data including IP address, date and time, requested URL, HTTP status, data volume, referrer, and browser type and version. This is required to provide the website securely and reliably, investigate errors and prevent misuse.
Hosting is provided by cyon GmbH, Basel, Switzerland, whose infrastructure is located in Switzerland. Under cyon’s default settings, raw server logs are deleted daily and therefore contain no more than 24 hours of access data. Where statistics or backups are enabled, the agreed retention periods apply.
4. Contact
If you contact us by telephone or email, we process the information you provide to respond, organize appointments and, where necessary, prepare or provide medical services. Medical information may constitute sensitive personal data and is also subject to professional confidentiality.
When you submit the contact form, your name, email address, optional telephone number and message are sent to the practice by email. The website does not store these messages in a database. Please do not submit sensitive medical information through this form. For medical documents, use the practice’s HIN email or contact the practice by telephone.
Correspondence is retained for as long as necessary to deal with the inquiry or to comply with statutory retention and documentation obligations.
5. Embedded services
Locally hosted fonts
The font files used on this website are served directly from the website’s own server. Loading the fonts does not establish a connection to Google Fonts or any other font provider.
Google Maps
A Google Maps map is embedded on the contact page. Opening that page may transmit technical data such as IP address and browser information to Google and may involve cookies or similar technologies. Google may process data outside Switzerland, including in the United States. Google’s privacy terms apply. Browser settings or content blockers can restrict these services, although this may affect website functionality.
6. Cookies and Google Analytics
We use Google Analytics 4 to analyse website usage statistically and improve our information services. Google Analytics is activated only after you expressly consent via the notice or “Privacy settings”. You can withdraw your consent at any time.
Usage, device and technical data may be transmitted to Google. Visits to medical pages may reveal health-related interests. Advertising features and personalised advertising are disabled.
Google Analytics uses cookies with a maximum lifetime of 60 days. Your choice is stored in your browser and remains in place until you change it or clear your browser data. Withdrawing consent stops further measurement and removes existing Analytics cookies. Data already transmitted to Google are not deleted retroactively.
Data are processed by Google Ireland Limited and Google LLC. Processing outside Switzerland, particularly in the USA, is possible. Further information is available in Google’s privacy policy.
The contact form continues to use a technically necessary session cookie to prevent abuse. A temporary sending restriction uses a hash derived from the IP address; message contents are not stored for this purpose. The statistics setting controls Google Analytics only; the separate Google Maps embed is described in section 5. No automated individual decision-making takes place.
7. Recipients and international transfers
Personal data is disclosed to service providers only where required to operate the website or process an inquiry, or where required by law. Google services may involve transfers to the United States and other countries. Providers rely on safeguards available under applicable data protection law.
8. Data security
Appropriate technical and organizational measures are taken to protect personal data against loss, misuse, unauthorized access and unlawful processing. Internet transmission cannot nevertheless be protected against every risk.
9. Your rights
Under applicable data protection law, you may request information about the processing of your personal data and ask for inaccurate data to be corrected or data to be deleted. Depending on the circumstances, additional rights may apply, including data disclosure or transfer and objection to processing. Contact the address above to exercise your rights. Suitable proof of identity may be requested.
10. Amendments
This policy may be updated if the website, services used or legal requirements change. The version published on this website applies.
