Cookie policy
How this website uses cookies and similar technologies.
This page is a translation. In the event of discrepancies, the German version prevails.
What are cookies?
Cookies are small files that can be stored on or read from your device when you visit a website. Similar technologies such as local storage, pixels, tags or comparable identifiers may be used for similar purposes.
Cookies and similar technologies may be used, for example, to provide basic website functions, store language settings, ensure security, analyse the use of a website or personalise content and advertising.
Which categories do we use?
Technically necessary cookies are required for the operation, the security or the website functions you expressly request. These technologies cannot be fully disabled if the corresponding website function is to be provided.
Functional cookies store, for example, language settings or other preferences you have chosen.
Analytics and statistics cookies help us understand how our website is used, which content is accessed and how we can improve the website.
Marketing and tracking cookies may be used to analyse the use of our website across individual pages or websites and to tailor content or advertising to interests.
External media and services may be used to provide content from external providers, for example videos, maps, social media content or other embedded services.
Consent and cookie settings
Technically necessary cookies may be used without prior consent, to the extent that they are required for the service you request.
Tessi Switzerland follows a privacy-friendly approach: marketing technologies and third-party services are generally activated only after you have given your consent.
For web analytics we use Umami. We operate Umami ourselves; it uses no cookies and creates no profiles across websites. There is therefore no cookie banner on this website. You can object to web analytics at any time, see Objecting to web analytics. Should technologies requiring consent be introduced in future, we will obtain your consent beforehand via a banner and extend the overview below; you will then be able to withdraw your consent at any time.
Declining non-necessary cookies does not impair basic use of the website. Individual convenience functions or embedded content may, however, be limited.
Cookies and services we use
This website uses no cookies and does not load any content, fonts or services from third-party servers. Web analytics runs on our own server webstats.tessi.ch. In detail, the following are used:
| Provider | Technology | Purpose | Category | Retention | Recipient country |
|---|---|---|---|---|---|
| Tessi Switzerland | Local Storage «tessi-lang» | Stores the selected language (DE/EN/FR/IT) | Functional, set on your explicit choice | until you delete it | none, stays locally in your browser |
| Tessi Switzerland | Umami Analytics, script from webstats.tessi.ch, without cookies | Visitor statistics, heatmaps and session replays to improve the website | Analytics | nothing stored on your device; on our server session replays 30 days, statistics 24 months | Switzerland, Tessi Switzerland data centre in Urdorf |
| Tessi Switzerland | Local storage “umami.disabled” | Storing your objection to web analytics | Technically necessary, set only on your objection | until you delete it | none, remains locally in your browser |
Objecting to web analytics
If you do not want your visit to be included in web analytics, you can deactivate it for this browser here. This sets the entry “umami.disabled” in local storage. The website remains fully usable.
Status: web analytics is active in this browser.
The setting applies only to the browser and device on which you make it. Clearing the site data in your browser cancels it.
Third-party providers
When third-party services are used, those providers may receive information about your device and your use of our website.
To the extent that third-party providers process personal data under their own responsibility, their data protection provisions apply in addition.
If data is disclosed to states outside Switzerland, the rules on international data transfers described in our privacy policy apply.
Retention period
Session cookies are generally deleted as soon as you close your browser.
Persistent cookies remain stored for the period stated in the cookie register or until you delete them yourself or withdraw your consent.
Browser settings
You can also manage, block or delete cookies via your browser settings. This may, however, limit certain functions of the website.
The local storage entry listed above is not removed via cookie management but by clearing the site data for this website in your browser. The stored language choice is then cancelled and the website appears in the language you navigate to.
The same applies to the entry “umami.disabled”: if you clear the site data, your objection to web analytics is cancelled.
Artificial intelligence
This website uses no cookies or comparable storage technologies for AI-assisted functions. Neither chatbots nor voice assistants are operated, and no profiles are created for AI-assisted personalisation.
Notes on the possibility that content on this website was created with the support of artificial intelligence can be found in the imprint and in the privacy policy.
Changes
We may adapt this cookie policy, in particular if the technologies used, the service providers or the legal requirements change.
