Privacy policy

1. General

The protection of your personal data is important to us. We process personal data in accordance with the Swiss Data Protection Act (DSG) and – where applicable – the EU General Data Protection Regulation (GDPR). This policy describes what data we collect on this website and what we use it for.

3. Access data (server logs)

When you visit this website, our web server automatically processes technical access data: IP address, date and time of access, page requested, browser and operating system used. This data is used solely to ensure the operation of the site, to analyse errors and to defend against attacks. It is not combined with other data sources and is automatically deleted after a short period.

4. Cookies and web analytics

For web analytics and to measure how well our advertising works, we use Google Analytics 4 (GA4) and other Google services. On your first visit, a notice asks whether you allow the cookies needed for this. Until you agree, Google sets no cookies and receives only cookieless signals – for example that a page was viewed – which cannot be used to recognise you. Analytics and advertising cookies are set only with your consent; your IP address is anonymised. If you decline, the website remains fully usable. Your choice is stored only in your browser. You can change or withdraw it at any time via the "Cookie settings" link at the bottom of every page. Data may be transferred to the USA in the process; Google is certified under the Swiss-U.S. Data Privacy Framework. For more information, see Google's privacy policy. To understand how this notice is used, we count anonymously, on our own server, how often it is shown and how often visitors accept or decline. Only the event and the time are stored – no IP address, no browser details and no cookies.

5. Fonts

For a consistent appearance, we use fonts hosted on our own server (self-hosted). The fonts are loaded directly from our server — no data is transmitted to Google or other third parties.

6. Contact form and contacting us

If you use our contact form, we process the data you provide (name, e-mail address, optional phone number, your concern and your message) in order to handle your enquiry. The data is transmitted in encrypted form to our own system environment and forwarded internally by e-mail to the responsible team. It is not passed on to third parties and is only retained for as long as is necessary to process the enquiry and the subsequent business relationship.

7. CO₂ calculator

Our CO₂ calculator processes technical vehicle data only (weight, CO₂ emissions, vehicle type). No personal data is collected or stored in the process.

8. Dealer platform

Supplementary terms apply to the registration for and use of our dealer platform (cockpit.co2-boerse.ch); these are communicated to you during registration. Data collected there (company and contact details, vehicle and processing data) is processed by us to provide our services.

9. Disclosure to third parties

We do not sell personal data. Data is only disclosed where this is necessary to provide our services (e.g. to IT and hosting providers that are contractually bound to confidentiality), where required by law, or where you have given your consent. Our systems are operated in Switzerland.

10. Data security

All data transmitted on this website is encrypted (TLS/HTTPS). We take appropriate technical and organisational measures to protect your data against loss, misuse and unauthorised access.

11. Your rights

You have the right to obtain information about the personal data we process, as well as to have it corrected, deleted or handed over. You may also object to processing and withdraw any consent you have given at any time. To do so, please contact [email protected].

12. Changes

We may amend this privacy policy as needed; the version published on this page applies. Last updated: October 2026
