2. This website
This website presents our services. It has no client account and no form. To make a request, you can call us, write to us, or request a call-back on our platform my.prevancia.ch, which has its own privacy notice. Our contact details are on the Contact page.
3. Data processed by this website
- Technical data: when you visit the website, our hosting provider automatically records the IP address, the date and time, the page requested and the browser type, to ensure the website works and is secure.
- Your messages: if you write to us or call us, we process the information you give us in order to reply and, if you wish, to search for your assets.
On this website we do not ask for your AHV number, an ID document or any health data. This website does not pass any data to a third-party service: it uses no cookies or audience analytics, and your browser does not contact any website other than prevancia.ch. Only our service providers, listed in section 5, process data on our behalf.
4. Cookies and audience measurement
This website uses no cookies, no audience measurement tools and no social media pixels. No consent banner is therefore needed. If this changes, we will ask for your consent beforehand.
Generic UTM parameters may appear in the address of some pages to identify the source of a visit, for example a campaign. They are not stored in a cookie: they are kept in your browser for the duration of your visit and deleted when you close the tab. We do not use them to identify or profile visitors, and we do not pass them to any analytics tool. Like any address requested, they appear in our hosting provider’s technical logs, which are kept for 30 days. When you click through to our platform my.prevancia.ch, these parameters are passed to it so that it knows where your request came from.
5. Recipients and service providers
- Nine Internet Solutions AG: website hosting, in the NTT Zurich 1 data centre in Rümlang (Switzerland); emergency access possible from Canada.
- Sanity AS provides the website’s content management tool and processes the account data of the people who write the content. According to Sanity, our project’s data is stored in Belgium (European Union); content and files may be cached in other regions depending on the services used. The website serves its own pages and images: your browser makes no calls to Sanity.
- OVH SAS: email (European Union).
Data may be accessible from the European Union, whose level of protection Switzerland recognises as adequate. Nine states that emergency access from Canada may be possible; the conditions applying to such access depend in particular on the legal system to which the entity concerned is subject.
6. Retention periods
- Hosting provider’s technical logs: 30 days, in Switzerland.
- Messages and emails: as long as needed to handle your request; if it leads nowhere, 12 months after the last exchange. If you become a client, for as long as our relationship requires, then archived or deleted in accordance with the applicable legal obligations.
7. Your rights
You can request access to your data, its rectification or erasure, and object to processing. Write to mondossier@prevancia.ch. We reply within 30 days.
