We, Viessmann Werke GmbH & Co KG, Allendorf (Eder), Germany (“Viessmann”), take the protection of your personal data very seriously and comply strictly with the provisions of data protection laws.
The recording, transfer, storage, processing and other use of personal data will also be referred to jointly as “processing” in the following.
Principles of data processing via the apps
Stored personal data will be deleted if you revoke your consent for storage, if the data are no longer necessary to fulfil the purpose of storage, or if storage of the data is not permitted on other legal grounds. Where required as a result of a statutory storage period, the data will not be deleted but will be kept for other uses. It is not mandatory to delete anonymous data.
Automatic data processing when accessing the apps
We automatically process data in server log files that are transferred to our servers by the apps. This is technically necessary for operation of the apps and serves the sole purpose of providing all functions of the apps. The following data are automatically stored in server log files:
- operating system used by the mobile user devices
- IP address of your mobile and device
- time of server request
- device ID of the mobile user device
These data are not combined with data from other sources.
The IP address is the internationally used unique identifier of the source of your internet connection at the time of allocation by your internet provider. The most usual form (IPv4) consists of four separate blocks of figures separated by periods. Generally, as a private user, you will use an IP address that does not remain the same because it is only assigned to you temporarily by your provider (“dynamic IP address”). In case of a permanently assigned IP address ("static IP address"), clear allocation of user data is possible in principle. Except for the purpose of pursuing unauthorized access to our website, we strictly do not use such personal data, but only evaluate on an anonymous basis, which of our web pages are accessed most frequently, how many times the website is accessed on a daily basis, and similar information.
Data processing as part of communication with heat generators
The purpose of the app is to control and analyse Viessmann heat generators. When a heat generator has been activated using the corresponding communication component (such as VitoConnect) in your app, its configuration and operating data, recorded errors, configuration settings, temperature profile (referred to collectively as “heating data") will be transferred to Viessmann servers, operated by Viessmann IT Service GmbH, located in the European Union, as part of commissioned data processing, and will be stored there. The app reads the data and makes such data available, as well as functions based on such data.
When creating a user account, you consent to heating data being used and disseminated as follows:
- The data are used to provide app functions, create push notifications (e.g., warnings, maintenance, failures), increase the operational safety of the system, improve system efficiency, correct deficiencies and improve service and system development by means of long-term research. The data will be processed by the following companies of the Viessmann Group for the following purposes all within the frame of commissioned data processing agreements with Viessmann: Viessmann Werke GmbH & Co KG (operation of the app); Viessmann Ltd. (sales and technical support for heating engineers); Viessmann Heiztechnik GmbH (further development of the app).
- If you have activated the appropriate feature in the apps, heating data, the address of the heat generator, your name and your telephone number will be transferred to a specialist craftsman approved by you in the app. You may withdraw this approval in the app at any time and therefore stop the data from being transferred.
- In the app it is possible for you to approve other users for your heat generator. After approval, heating data will be transferred from your heat generator to these users as well. You may withdraw this approval in the app at any time and therefore stop the data from being transferred.
Using a pseudonym means that neither third parties nor any other companies in the Viessmann Group are able to allocate system data to you personally. Personal data (such as name, address, system users) will not be transferred. Viessmann guarantees that no other companies will be given access to data without the pseudonyms, except the aforementioned group companies.
- The use and possible transmission of data in a form that uses only a pseudonym is performed for the purpose of increasing the security of system operation, improving system efficiency, rectifying failures, and improving service and system development by other companies and by third parties. Using anonymous data means that neither third parties nor Viessmann are able to allocate system data to you personally and such data may not be allocated to you retroactively, either. Personal data (such as name, address, system users) will not be transferred.
- Personal data may also be used to review warranty cases and to protect Viessmann against unauthorized claims.
