3. What data we process and for what purpose

3.1 Provision of the website / server log files

When you access this website, our hosting provider automatically collects technical data transmitted by your browser. This includes, in particular:

  • IP address

  • Date and time of the request

  • Page / file accessed

  • Browser and operating system used

  • Referrer URL (previously visited page)

 

This data is processed to ensure trouble-free operation, to safeguard our systems and for statistical analysis. The legal basis is our legitimate interest in maintaining a secure and fully functional website.

 

Hosting: This website is operated on the Wix.com platform. The provider is Wix.com Ltd. or its affiliated companies. As part of the hosting service, data may also be processed outside Switzerland, including in the EU and the USA.

 

3.2 Contact form

When you use our contact form, we collect the data you enter:

  • Title

  • First name, surname

  • Email address

  • Your message

 

This data is used exclusively to process your enquiry and to contact you. The legal basis is the fulfilment of pre-contractual measures or your interest in receiving a response to your enquiry.

We ask that you do not provide any particularly sensitive personal data (e.g. detailed health information) in the message field. For medical enquiries, we recommend contacting us by telephone or arranging a face-to-face consultation.

 

3.3 Appointment booking (“Book a consultation”)

We use the Wix booking function (Wix Bookings) for online appointment booking. The data required to arrange an appointment (e.g. name, contact details, preferred appointment time) is collected and processed by Wix on behalf of the practice. This applies in particular to the requested treatment, as well as any additional concerns and information provided by the user.

 

3.4 Cookies and similar technologies

This website may use cookies – small text files that are stored on your device. Technically necessary cookies are required for the website to function (e.g. language settings, session management on the Wix platform). Where additional analytics or marketing cookies are used, we will inform you separately and, where required by law, obtain your consent.

 

3.5 Linked social media channels

On the website, you will find links to our profiles on Instagram and TikTok. These are simply links (not embedded social plugins). When you click on them, you will be redirected to the respective platform, where the privacy policy of the relevant provider applies:

 

 

3.6 Email communication

For communication, we use, amongst other things, an address provided by Health Info Net (HIN) – a highly secure email system designed for the healthcare sector in Switzerland. Messages sent via HIN are encrypted between HIN participants; however, end-to-end encryption cannot be guaranteed when communicating with external email addresses not connected to HIN.

 

4. Disclosure of data

Your personal data will only be disclosed to third parties to the extent that this is necessary to provide the services mentioned (e.g. to Wix as a hosting/booking service provider), is required by law, or you have given your consent. Your data will not be sold to third parties.

 

5. Retention period

We process and store your personal data only for as long as is necessary to fulfil the purposes set out above or in accordance with statutory retention periods (e.g. medical documentation requirements).

 

6. Your rights

Under the Swiss Data Protection Act, you have the following rights in particular:

  • Information as to whether and what data we process about you

  • Rectification of inaccurate data

  • Erasure of your data, provided this does not conflict with any statutory retention obligations

  • Restriction of processing

  • Objection to certain processing activities

  • Receipt or transfer of your data in a commonly used format (data portability)

 

To exercise these rights, please contact us using the contact details provided in section 2. We reserve the right to verify your identity before processing your request.

You also have the right to lodge a complaint with the relevant supervisory authority – in Switzerland, this is the Federal Data Protection and Information Commissioner (FDPIC), www.edoeb.admin.ch.

 

7. Data security

We take appropriate technical and organisational measures to protect your data against unauthorised access, loss or misuse. However, complete protection against all risks associated with data transmission over the internet cannot be guaranteed.

 

8. Changes to this Privacy Policy

We reserve the right to amend this Privacy Policy to bring it into line with changes in the legal landscape or changes to the service and data processing. The current version is available on this page.
