This data may include in particular master data and contact data of data subjects, data on processes, contracts, other proceedings and their contents. Cloud service providers also process usage data and metadata that they use for security and service optimization purposes.

If we use cloud services to provide documents and content to other users or publicly accessible websites, forms, etc., providers may store cookies on users' devices for web analysis or to remember user settings (e.g. in the case of media control).

Web analysis is used to evaluate the visitor traffic on our website and may include the behaviour, interests or demographic information of users, such as age or gender, as pseudonymous values. With the help of web analysis we can e.g. recognize, at which time our online services or their functions or contents are most frequently used or requested for repeatedly, as well as which areas require optimization.

In addition to web analysis, we can also use test procedures, e.g. to test and optimize different versions of our online services or their components.

Unless otherwise stated below, profiles, i.e. data aggregated for a usage process, can be created for these purposes and information can be stored in a browser or in a terminal device and read from it. The information collected includes, in particular, websites visited and elements used there as well as technical information such as the browser used, the computer system used and information on usage times. If users have agreed to the collection of their location data from us or from the providers of the services we use, location data may also be processed.

Unless otherwise stated below, profiles, that is data summarized for a usage process or user, may be created for these purposes and stored in a browser or terminal device (so-called "cookies") or similar processes may be used for the same purpose. The information collected includes, in particular, websites visited and elements used there as well as technical information such as the browser used, the computer system used and information on usage times. If users have consented to the collection of their location data or profiles to us or to the providers of the services we use, these may also be processed, depending on the provider.

The IP addresses of the users are also stored. However, we use any existing IP masking procedure (i.e. pseudonymisation by shortening the IP address) to protect the user. In general, within the framework of web analysis, A/B testing and optimisation, no user data (such as e-mail addresses or names) is stored, but pseudonyms. This means that we, as well as the providers of the software used, do not know the actual identity of the users, but only the information stored in their profiles for the purposes of the respective processes.

• Processed data types: Usage data (e.g. websites visited, interest in content, access times); Meta, communication and process data (e.g. IP addresses, time information, identification numbers, consent status).
• Data subjects: Users (e.g. website visitors, users of online services).
• Purposes of Processing: Web Analytics (e.g. access statistics, recognition of returning visitors); Profiles with user-related information (Creating user profiles).
• Security measures: IP Masking (Pseudonymization of the IP address).
• Legal Basis: Consent (Article 6(1)(a) GDPR).

• Matomo: Matomo is software that is used for the purposes of web analysis and reach measurement. As part of the use of Matomo, cookies are generated and stored on the user's terminal device. User data collected through the use of Matomo is processed only by us and is not shared with third parties. The cookies are stored for a maximum period of 13 months: https://matomo.org/faq/general/faq_146/; Legal Basis: Consent (Article 6(1)(a) GDPR); Retention period: The cookies have a maximum storage period of 13 months.

We process personal data for the purposes of online marketing, which may include in particular the marketing of advertising space or the display of advertising and other content (collectively referred to as "Content") based on the potential interests of users and the measurement of their effectiveness. 

For these purposes, so-called user profiles are created and stored in a file (so-called "cookie") or similar procedure in which the relevant user information for the display of the aforementioned content is stored. This information may include, for example, content viewed, websites visited, online networks used, communication partners and technical information such as the browser used, computer system used and information on usage times and used functions. If users have consented to the collection of their sideline data, these can also be processed.

The IP addresses of the users are also stored. However, we use provided IP masking procedures (i.e. pseudonymisation by shortening the IP address) to ensure the protection of the user's by using a pseudonym. In general, within the framework of the online marketing process, no clear user data (such as e-mail addresses or names) is secured, but pseudonyms. This means that we, as well as the providers of online marketing procedures, do not know the actual identity of the users, but only the information stored in their profiles.

The information in the profiles is usually stored in the cookies or similar memorizing procedures. These cookies can later, generally also on other websites that use the same online marketing technology, be read and analyzed for purposes of content display, as well as supplemented with other data and stored on the server of the online marketing technology provider.

Exceptionally, clear data can be assigned to the profiles. This is the case, for example, if the users are members of a social network whose online marketing technology we use and the network links the profiles of the users in the aforementioned data. Please note that users may enter into additional agreements with the social network providers or other service providers, e.g. by consenting as part of a registration process.

As a matter of principle, we only gain access to summarised information about the performance of our advertisements. However, within the framework of so-called conversion measurement, we can check which of our online marketing processes have led to a so-called conversion, i.e. to the conclusion of a contract with us. The conversion measurement is used alone for the performance analysis of our marketing activities.

Unless otherwise stated, we kindly ask you to consider that cookies used will be stored for a period of two years.
