2. Cookies

Our website uses cookies. Cookies are small text files that are installed in a computer system by way of the internet browser and stored there.

Many websites and servers use cookies. Cookies meanwhile often contain a so-called cookie ID. This ID is a unique identifier of the cookie and consists of a string of characters by which the website and server may be related to a specific internet browser where the cookie was installed. These cookies enable your individual browser to be distinguished from other internet browsers containing different cookies. A specific internet browser may thus be recognized and identified by means of a unique cookie ID.

The use of cookies enables us to provide you with more user-friendly services that could not be realized without them at all, or only to a limited extent. The cookies are used in the interest of providing and optimizing a functional and comfortable online offer.

You can prevent the installation of cookies in the settings of your internet browser or also set your browser to informing you as soon as cookies are sent. In addition, you can also delete already installed cookies by means of an internet browser or other software program. Please note, however, that you may not be able to use all the functions of our or other online offers if you deactivate cookies in your internet browser.

3. Web analysis (INFOnline)

Our application uses the "SZMnG" measurement system provided by INFOnline GmbH ( to determine statistical parameters concerning the use of our offers. This usage measurement is aimed at determining the usage intensity, number of usages and users of our application, as well as their surfing behaviour statistically – based on a consistent standard procedure – and thus at obtaining data that are comparable across the market.

The usage statistics for all digital offers that are members of the German Audit Bureau of Circulation (IVW – or take part in studies by the Working Group for Online Media Research (AGOF - are regularly converted into reaches by AGOF and the media analysis working group agma (agma - and published with the performance value "unique users", as well as by the IVW with the performance values "page impressions" and "visits". These reaches and statistics may be viewed at the respective websites.

(a) Legal basis of the processing

The measurement using the SZMnG measuring process provided by INFOnline GmbH is performed with a legitimate interest as per GDPR article 6.1.f.

The personal data are processed for the purpose of creating statistics and defining user cate-gories. The statistics enable us to track and document the use of our offer. The user categories form the basis for an interest-oriented provision of advertising materials and/or promotional measures. A usage measurement that ensures comparability with other market participants is indispensable for marketing this application. Our legitimate interest arises from the economic exploitability of the findings obtained from the statistics and user categories and the market value of our application – also in direct comparison with third-party applications - derivable by means of the statistics.

We also have a legitimate interest in providing the pseudonymized data to INFOnline, AGOF and IVW for market research (AGOF, agma) and statistical purposes (IVW, INFOnline). And we furthermore also have a legitimate interest in providing the pseudonymized data to INFOnline for the further development and provision of interest-oriented advertising materials.

(b) Data types

INFOnline GmbH collects the following data regarded as person-related under the GDPR:

- IP address: On the Internet, each device requires a unique address to transmit in-formation: the IP address. Because of how the Internet functions, it is technically necessary for the IP address to be stored, at least for a short period. IP addresses are truncated to 1 byte before any processing. Further processing is only per-formed on anonymised IP addresses. No IP addresses that have not been truncat-ed are saved or processed.

- A randomly generated Client ID: To allow computer systems to be recognised, the further processing uses either a third-party cookie, a first-party cookie, a local stor-age object or a signature that is compiled from diverse information from your browser that is transmitted automatically. This identification is explicit for a brows-er, as long as the cookie or local storage object is not deleted. It is possible to measure the data and to subsequently assign it to the respective client identifier by accessing other websites that also use the measuring method ("SZMnG") of IN-FOnline GmbH. The validity of the cookie is restricted to a maximum of 1 year.

(c) Data use

The INFOnline GmbH measurement process used in this application collects usage data. This happens to determine the performance values "page impressions", "visits" and "clients" and generate other parameters from them (e.g. qualified clients). In addition to this, the measured data are also used as follows:

- So-called geolocalization, i.e. tracing of your website visit to the place where it is displayed, is only applied on the basis of the anonymized IP address and only down to the geographical level of the German Länder/regions. The geographical information obtained this way cannot be used to draw conclusions about a user's actual place of residence in any case. - The usage data of a technical client (e.g. a browser in a device) are merged across applications and stored in a database. These data are used for the technical estimation of the social information age and gender and provided to the service providers of AGOF for further reach processing. In the AGOF study, a random sample is used for the technical estimation of social features: age, gender, nationality, occupation, marital status, general information on the household, household income, place of residence, internet use, online interests, place of use, user type.

(d) Data storage period

The full IP address is never stored by INFOnline GmbH. The truncated IP address is stored for 60 days maximum. The usage data in combination with the unique identifier are stored for a maximum of 6 months.

(e) Data disclosure

Neither the IP address nor the truncated IP address are disclosed. To create the AGOF study, data with client identifiers are disclosed to the following service providers of AGOF: - Kantar Deutschland GmbH ( - Ankordata GmbH & Co. KG ( - Interrogare GmbH (

(f) Rights of the data subject

See section D (below).

(g) Opt-out

We offer our users a separate opt-out option in our website. This serves to install a cookie in your system that signals to our system not to store the user's data: Opt-Out

(h) Further information

Further information on the data protection in the measuring process is available from the website of INFOnline GmbH (, which operates the measuring system, from the data protection page of AGOF ( and from the data protection page of IVW (
