Privacy policy
Version: 9 November 2026
1. Who is responsible
Kevin Kuhn Consulting GmbH, Himmelrichstrasse 18, 6010 Kriens, Switzerland, operates this website and is responsible for the processing of your personal data. Swiss data protection law (FADP) applies. For questions about data protection, write to info@volt-os.ch; your contact is Karol Bonk.
2. What data we process and why
When you visit the website. Our hosting provider logs the IP address, the time, the page requested and the browser used for every request (server logs). We need this data to run the website and protect it against attacks. The hosting provider deletes it after 7 days at the latest. This website sets no cookies, uses no analytics or tracking services and embeds no third-party content; the fonts are served from our own server.
In the contact form. When you use the contact form, we process your name, your company, your phone number and/or email address, your question, the language of the page and the time of the request. We need this to answer your request. The request is stored on our server and delivered to us by email; if you gave an email address, you receive a confirmation. We store your IP address only as a truncated hash value, to prevent abuse of the form. While you type the company name, we suggest matching companies from the commercial register: our server queries Zefix, the Swiss Central Business Name Index (Federal Office of Justice), with the typed text; Zefix receives only that text.
By email. If you write to info@volt-os.ch, we process your details to reply to you.
3. Who receives the data and where it goes
We do not pass your data to third parties for marketing. To run the website, we work with service providers who process your data on our behalf. Some data goes to the USA; the safeguard under the Swiss Data Protection Act (FADP) is stated for each provider:
- Railway Corporation, USA: hosting of the website and storage of the form requests on servers in Amsterdam (EU); access and server logs also in the USA. Certified under the Swiss-U.S. Data Privacy Framework.
- Resend (Plus Five Five, Inc.), USA: sending the emails from the contact form; the data is stored in the USA. Safeguarded by the EU standard contractual clauses with the Swiss amendments (Art. 16 para. 2 let. d FADP).
- Google Cloud EMEA Limited, Ireland, and Google LLC, USA: Google Workspace for our mailbox info@volt-os.ch. Google LLC is certified under the Swiss-U.S. Data Privacy Framework.
The EU member states provide adequate data protection according to the Swiss Federal Council.
4. How long we keep the data
We delete contact form requests from the server after 30 days. We keep emails as long as we need them to answer your request and for any further cooperation, and as long as statutory retention duties apply; after that we delete them. The hosting provider deletes server logs after 7 days at the latest.
5. Your rights
You can ask at any time which data we process about you, request its correction or deletion, and object to the processing. Write to info@volt-os.ch; we usually answer within 30 days. The information is free of charge. If you believe we do not process your data lawfully, you can contact the Federal Data Protection and Information Commissioner (FDPIC).
