In this Cookie policy, the CSS Group explains how it uses the data generated when you visit our websites.
Content from external providers is integrated into our websites to improve your surfing experience and for statistical, market research and advertising purposes. These external providers use cookies to manage their services. Cookies are therefore installed (locally) on your computer's hard drive when you visit our websites.
These are small units of information that the web browser stores locally on the user's computer. We need this content to allow you to use the website and to optimise the experience (e.g. personalisation).
Most of the cookies we use are known as ‘session’ cookies. They are deleted automatically at the end of your visit. Other cookies remain stored on your device until you delete them. These cookies enable us to recognise your browser the next time you visit us. This allows you to make optimal use of our website and enables us to deliver content that is tailored to your needs.
Although only anonymous data is collected and processed, you can still use our websites without cookies by deactivating them in your browser.
Important: Please note that some websites cannot function fully without cookies.
You can also set an opt-out cookie for each external provider. However, if you do so you will no longer be able to use certain functions, and you may experience restrictions in the use of our websites.
Details on how third-party providers handle your personal data are given in their individual privacy policies, such as those issued by Facebook, Instagram, Twitter, Pinterest, TikTok, LinkedIn, Google and Adobe Systems. The CSS data protection provisions do not apply to data processing by these external providers. Please note that, as a website provider, we do not receive any information from these external providers about the content of the data that is transmitted, or its use. By using products such as Facebook, Twitter, etc., you declare that you agree to their particular data protection provisions.
Where CSS is subject to the EU's General Data Protection Regulation, cookies required to run electronic communications or to provide certain functions requested by you (such as the premium calculator) are stored on the basis of Art. 6 para. 1 f of the Regulation. The website operator has a legitimate interest in storing such cookies in order to ensure the technically flawless and optimised provision of its services. If other cookies (such as those which analyse your surfing behaviour) are stored, these are treated separately under the present Privacy Policy.
The following services and tools are used on css.ch (incl. subdomains and subsites):
CSS uses the Adobe Real-Time Customer Data Platform (RT-CDP). The RT-CDP enables CSS to collate data from a variety of data sources (information about online use and use of CSS products and services, as well as demographic data) and to save it centrally as a client-marketing profile.
The Journey Optimizer is used to provide personalised user experiences across a variety of channels. We use Journey Optimizer to increase the relevance of content by delivering it in personalised form.
CSS uses the services of Adobe Customer Journey Analytics (Adobe Systems Software Ireland Limited, 6 Riverwalk, Naas Road, Dublin 24, Ireland) to automatically collect data on your use of our websites. In this way, CSS finds out how its web services are being used and learns about users' surfing behaviour in order to understand the relevance of content and optimise the user experience.
CSS uses Adobe Target to personalise relevant data-driven content on the websites in order to provide a user-centric experience.
CSS uses Adobe Campaign for personalised email marketing (e.g. newsletters). Data is stored locally (in Switzerland) on CSS servers.
The Adobe IMS / IO Service enables content from Adobe AEM (CMS) to be provided for personalisation in Target.
CSS uses the services of Google Analytics (Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA) to automatically collect data on your use of our websites. In this way, CSS finds out how its web services are being used and learns about users' surfing behaviour in order to understand the relevance of content and optimise the user experience.
Remarketing analyses your surfing behaviour and, based on this, shows you personalised CSS advertising while you surf the internet, and use a mobile app or the Google search engine. This enables more specific interest-related, personalised advertising related to your previous usage and surfing behaviour on a given device (such as your smartphone) to be shown on another of your devices (such as a tablet or PC). Google AdWords analyses clicks on Google, and CSS pays on a per-click basis when users access a CSS advert or website. If you have given the appropriate permission, Google will link your web and app browser clicks to your Google account for this purpose. In this way, the same personalised advertising can be shown on any device on which you log in with your Google account. You can object permanently to cross-device remarketing or targeting by deactivating personalised advertising in your Google account. Where CSS is subject to the EU’s General Data Protection Regulation, the collected data is collated in your Google account only if you have given your permission. You can give or revoke your permission via Google (Art. 6 para. 1 a General Data Protection Regulation). Where data is collected that is not collated with that of your Google account (for example because you do not have a Google account or have refused permission), the collection of your data is based on Art. 6 para. 1 f of the General Data Protection Regulation. The website provider’s legitimate interest is based on its interest in the anonymised analysis of website visitors for promotional purposes.
This website uses the Google Marketing Platform (formerly DoubleClick), a web analytics service offered by Google. This optimises interaction with Google AdWords. It sets cookies when you view an advert or click on one of our banners on a partner website. This is done so that we can show you banners that are of interest to you. The cookie allows us to record certain data about interaction from your browser with certain on-screen content. We also record whether you have viewed an advert, clicked on it, or entered into a contract with CSS on this basis. The information on the use of our websites stored locally in the cookie (user- or client-side) is transferred to the Google servers and stored there.
To improve the user experience and to quickly clarify questions, we offer you communication via a chatbot system (SIA). We use the Dialogflow service of Google (Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA) to detect the intent of user input (Natural Language Understanding, or NLU). In addition, our system uses the Azure OpenAI service from Microsoft (Microsoft Schweiz GmbH, The Circle, P.O. Box, 8058 Zurich Airport, Switzerland) to answer more complex questions based on publicly available information from the css.ch website. This uses a Large Language Model (LLM) to analyse your query and generate a response.
Data processing and location (Azure OpenAI): The processing of your chat input, which is necessary to generate a response via Azure OpenAI, usually takes place within the Microsoft Azure cloud region Switzerland North. This ensures that your data resides in Switzerland and complies with the requirements of the Swiss Data Protection Act (DSG).
No training with customer data: Microsoft has contractually promised that your inputs (prompts) and the responses (completions) generated through the Azure OpenAI service will not be used to improve or train the underlying AI model. Your interactions will remain confidential and will not be used for sharing with the stand-alone OpenAI organization.
Use of content: The chatbot generates its answers on the basis of the public web data provided by us (css.ch). It is not analysed or linked to your personal contract or client data, which is not already publicly available.
No personalised data: No personalised or particularly sensitive data about you that would allow conclusions to be drawn about your person will be evaluated or stored. Please do not enter any sensitive information (such as health data) in the chatbot entries.
Purpose of analysis: All user entries are analysed solely for the purpose of recognising the user’s intent and generating a reply, after which corresponding answers and CSS content are shown to the user.
This website uses the conversion tracking technology of Microsoft Corporation (One Microsoft Way, Redmond, WA 98052-6399, USA).

Only the total number of clicks and conversions is analysed, and pseudonymised user profiles are created. Microsoft uses the information collected to display personalised ads that could be particularly relevant to users. No personal information on the identity of the user is collected.
You can refuse cookies and stop Microsoft from processing the information obtained in this way. You can do so via the browser setting, which disables the automatic placing of cookies in general. Or you can prevent cookie placement, processing and use by Microsoft for personalised advertising. Further information on data protection and the cookies used by Microsoft.
