IV. General information and regulations for Viessmann websites and apps

These provisions apply in addition to the provisions for private users and the provisions for business users for Viessmann websites and apps. Some of our apps have their own additional data protection statements. The Viessmann Apps ViCare and Vitotrol Plus data protection statement can be found under the following link:

Data processing by accessing our Internet pages and using our apps

Viessmann automatically collects and stores information in its server log files that your browser or app transmits to us. Viessmann cannot assign this data to individual persons. This data is not merged with other data sources. These are:

■      Browser type/ version

■      Operating system used

■      Referrer URL (the previously visited page)

■      Host name of the accessing computer (IP addresses v4 and v6)

■      Time of the server request

The IP address is the globally valid identification of your computer at the time of allocation by your Internet provider and consists, in its currently most common form (IPv4), of four blocks of digits separated by dots. In most cases, as a private user, you will not use a constant IP address, as this is only temporarily assigned to you by your provider (so-called "dynamic IP address"). With permanently assigned IP addresses (so-called "static IP addresses"), a clear assignment of user data via this feature is technically easy.

The mentioned data will be processed by us for the following purposes:

■      Ensuring a smooth connection to the website   

■      Ensuring comfortable use of the aforementioned website

■      Evaluation of system security and system stability

■      For further administrative and statistical purposes   

The personal data of the server log files is processed on the basis of Art. 6 para. 1 lit. f DSGVO. This authorisation allows the processing of personal data in the "legitimate interest" of the person responsible, provided that your fundamental rights, freedoms or interests do not prevail. Our legitimate interest is in the easier administration and the ability to detect and track hacking. You can object to this data processing at any time if there are reasons which exist in your particular situation and which contradict the data processing. All you need to do is send an e-mail to the data protection officer. Our legitimate interest follows from the purposes listed above for data collection. Under no circumstances do we use the data collected for the purpose of drawing conclusions about you personally.

The server log files with the above data are automatically deleted after 30 days or anonymised if used for statistics. We reserve the right to store the server log files for longer if facts exist which suggest the assumption of unauthorised access (such as an attempt at hacking or a so-called DDOS attack).

Linking to external websites

This data protection statement applies exclusively to the Viessmann websites and apps. These may contain links to third-party websites. This data protection statement does not extend to these. If you leave the Viessmann websites and apps in order to visit the services of a third-party provider, we recommend that you also carefully read this provider's data protection statement.

Information on cookies and the use of analysis tools

The processing of personal data through cookies and analysis tools (Google Analytics and Google Tag Manager, Google Adwords Conversion Tracking, Third-Party-Cookies, Re-Targeting-Technologies, Google Remarketing, Facebook Remarketing and Inspectlet) is based on Art. 6 Para. 1 lit. f DSGVO. This authorisation allows the processing of personal data in the "legitimate interest" of the person responsible, provided that your fundamental rights, freedoms or interests do not prevail. Our legitimate interest is to analyse the use of our website.

The processing of personal data by Google AdWords (list all retargeting technologies) is based on Art. 6 Para. 1 lit. f DSGVO. This authorisation allows the processing of personal data in the"legitimate interest" of the person responsible, provided that your fundamental rights, freedoms or interests do not prevail. Our legitimate interest is in the personalised display of targeted advertising and the statistical analysis of the effectiveness of advertising (e.g. determining how many clicks on an advertising banner have led to a purchase from our website).

Viessmann uses so-called cookies in several places on its websites and in its apps. They serve to make our website more user-friendly, effective and secure. Cookies are small text files that are stored on your computer and saved by your browser. Most of the cookies we use are so-called "session cookies". They are automatically deleted at the end of your visit. Cookies do not cause any damage to your computer and do not contain any viruses.

Viessmann also uses analysis tools for this purpose, such as Web Trends or Google Tag Manager (Firebase). The data provided and used is collected and stored completely anonymously. This data may also be stored outside the United Kingdom or the European Union.

When implementing and using analysis tools and tracking technologies, we make personal data anonymous as quickly as possible either on the part of the provider, regulated by appropriate contracts, or within the scope of our first use, so that the right to information on your part cannot be exercised on all technologies listed below.

You can prevent the transmission of such data by making the appropriate settings in your browser, app or the operating system environment (iOS, Android). However, this may lead to problems in calling up, operating or functionality of the content or service offered. You will find a deactivation option (opt-out) for the cookies of the service we use from Taboola, Inc. under the following link:

In addition, we use cookies in some cases to measure the success and optimise our advertising activities. We use the conversion tracking of Adform Germany GmbH (hereinaf ter referred to as Adform). A cookie is set as soon as you have contact with a Viessmann advertising medium (e.g. advertising banner) placed via Adform. The cookie contains an advertising ID and is valid for 60 days. There are no features (e.g. complete IP address, first name, surname, address, e-mail address) contained, by means of which you can be personally identified. However, the advertising ID tells us which advertising material drew your attention to Viessmann. Under no circumstances does the Viessmann Group combine the advertising ID with personal data. Users who do not wish to participate in conversion tracking can deactivate the Adform cookie via their browser at

Google Analytics and Google Tag Manager

This website uses Google Analytics, a web analysis service of Google Inc. ("Google"). Google Analytics uses "cookies", which are text files placed on your computer, to help the website analyse how users use the site. The information generated by the cookie about your use of this website is usually transferred to a Google server in the USA and stored there. However, if IP anonymisation is activated on this website, Google will reduce your IP address within Member States of the European Union or in other states party to the Agreement on the European Economic Area beforehand. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. On behalf of the operator of this website, Google will use this information to evaluate your use of the website, to compile reports on website activity and to provide the website operator with other services relating to website and Internet use. The IP address transmitted by your browser in the context of Google Analytics is not merged with other Google data.

You may refuse the use of cookies by selecting the appropriate settings on your browser, however, please note that if you do this you may not be able to use the full functionality of this website. You can also prevent Google from collecting the data generated by the cookie and relating to your use of the website (including your IP address) and from processing this data by Google by downloading and installing the browser plug-in available under the following link:

For further information on terms of use and data protection, please  visit or

We would like to point out that Google Analytics has been extended to include the "anonymizeIp"function on this website to ensure that IP addresses are collected anonymously (IP masking).

This website also uses the Google Tag Manager. This service allows website tags to be managed through an interface. The Google Tool Manager only implements tags. This means that no cookies are used and no personal data is collected. The Google Tool Manager triggers other tags, which in turn collect data if necessary. However, the Google Tag Manager does not access this data. If a deactivation has been made at domain or cookie level, it remains valid for all tracking tags if they are implemented with the Google Tag Manager.

Deactivating Google Analytics

You can prevent the collection of data by Google Analytics by clicking on the following button. An opt-out cookie is set to prevent future collection of your data when you visit this website:


Google Adwords Conversion Tracking

As a Google AdWords customer, Viessmann uses Google Conversion Tracking, an analysis  service from Google Inc. (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA;"Google"). Google AdWords sets a cookie on your computer ("conversion cookie") if you have accessed our website via a Google ad. These cookies expire after 30 days and are not used for personal identification. If you visit certain pages of ours and the cookie has not expired, we and Google may detect that someone has clicked on the ad and has been redirected to our site. Each AdWords customer receives a different cookie. Cookies cannot therefore be traced via the websites of AdWords customers. The information collected using the conversion cookie is used to generate conversion statistics for AdWords customers who have opted for conversion tracking. AdWords customers see the total number of users who clicked on their ad and were redirected to a page with a conversion tracking tag.

However, they do not contain any information with which users can be personally identified.

If you do not wish to participate in tracking, you can object to this use by preventing the installation of cookies by setting your browser software accordingly (deactivation option). They are then excluded from the conversion tracking statistics. For more information and Google's privacy policy , please visit:


Viessmann makes use of a number of advertising partners who help to make the Internet offer and the websites more interesting for you. For this reason, cookies from partner companies are also stored on your hard drive when you visit the websites. These are temporary/permanent cookies that are automatically deleted after the specified time. These temporary or permanent cookies (lifetime 14 days to 10 years) are stored on your hard disk and delete themselves after the specified time. The cookies of our partner companies also only contain pseudonymous, usually even anonymous data. This includes, for example, data on which products you have looked at, whether something was purchased, which products were searched for, and so on.

Some of our advertising partners collect information about which pages you have visited before or which products you have been interested in, for example, in order to be able to show you the advertising that best suits your interests. This pseudonymous data will never be combined with your personal data. Their sole purpose is to enable our advertising partners to address you with advertising that might actually be of interest to you.

Re-Targeting Technologies

Our websites use so-called re-targeting technologies. We use these technologies to make our website more interesting for you. This technology makes it possible to address Internet users who are already interested in our products with advertising on the websites of our partners. We are convinced that the insertion of personalised, interest-related advertising is generally more interesting for the Internet user than advertising that has no such personal reference. The insertion of these advertising materials on the pages of our partners is based on cookie technology and an analysis of the previous user behaviour. This form of advertising is completely pseudonymous. No user profiles are merged with your personal data.

By using our site, you consent to the use of so-called cookies and thus to the collection, storage and use of your user data. Furthermore, your data is stored in cookies beyond the end of the browser session, so that it can be called up again the next time you visit the website, for example. You can revoke this consent at any time with future effect by refusing to accept cookies in your browser settings.

Google Remarketing

We use the remarketing technology of Google Inc. (1600 Amphitheatre Parkway, Mountain View,CA 94043, USA; "Google"). This technology allows users who have already visited our website and online services and are interested in the offer, to be addressed again through targeted advertising on the pages of the Google Partner Network. The insertion of the advertisement takes place via the use of cookies, which are small text files that are stored on the user's computer.The text files can be used to analyse user behaviour when visiting the website and can then be used for targeted product recommendations and interest-based advertising.

If you do not wish to receive interest-based advertising, you can disable Google's use of cookies for these purposes by visiting Alternatively, you can disable the use of cookies by third parties by visiting the deactivation page of the Network Advertising Initiative at and implementing the additional opt-out information mentioned there. For more information about Google Remarketing and Google's privacy policy, please visit:

By using our offers, you agree to the processing of data collected about you by Google, in the manner described here and for the aforementioned purpose. Please note that Google has its own privacy policy, which is independent of ours. We assume no responsibility or liability for these policies and procedures.

Facebook Remarketing

This website uses Facebook's remarketing or "custom audience" function. This feature enables us to target visitors to our website with advertisements by delivering personalised, interest-based ads to visitors to our website when they visit Facebook. Facebook uses cookies to analyse website usage, which forms the basis for creating interest-based advertisements.

To do this, Facebook stores a small file with a sequence of numbers in the browsers of visitors to our website. This number is used to record visitors to the website and anonymised data on the use of the website. No personal data of visitors to the website is stored. If you visit Facebook below, you will see ads that are highly likely to include previously accessed product and information areas. If you do not want the data to be collected by Facebook, you can refuse to save it by clicking on the following link: If you use several browsers, you must carry out the process individually.


Data is collected and stored on this website by the web analysis service Inspectlet. Usage profiles are created from the data using pseudonyms. They are used to analyse visitor behaviour and are evaluated to improve the handling of our website. Cookies (small text files) may be used for this purpose, which are stored locally on the visitor's computer and thus enable recognition when the user visits our website again.
