b) Collection, processing and use of data in INFOnline GmbH measuring methods

Our app uses INFOnline GmbH’s ( measuring method („SZMnG“) to determine statistical indicators regarding the use of our services. This method is aimed at statistically establishing the intensity of use, number of users of a specific website and their web surfing behaviour – on the basis of a uniform standard procedure – and, hence, obtaining figures that are comparable all over the market. For websites with a membership in Informationsgemeinschaft zur Feststellung der Verbreitung von Werbeträgern e.V. (IVW - German Audit Bureau of Circulation) or participating in surveys by Arbeitsgemeinschaft Online-Forschung e.V. (AGOF - Working Group for Online Media Research], the statistical usage data is regularly processed by means of reach capacity and published under the performance value marker of “Unique User” by AGOF and Arbeitsgemeinschaft Media-Analyse e.V. (agma -. Working Group for Media Analyses), as well as under “Page Impressions” and “Visits” by IVW. These reach capacity values and statistics and can be viewed on the organizations’ respective websites.

I. Basis for data processing

Measuring carried out by INFOline GmbH by means of the measuring method SZMnG is performed with a lawful interest according to Art. 6 Par. 1 lit. f) GDPR. Purpose of the processing of personal data is the composing of statistics with the intent of compiling user categories. The statistics serve as a means for us to comprehend and document the usage of our offered services. The user categories form the basis for providing personalised advertising media and advertising measures respectively. For purposes of marketing this application, measuring usage is pivotal, so as to allow for comparability to other market participants. Our lawful interest arises from economic usability derived from insights gathered from statistics and user categories, as well as the market value of our application, also in comparison to applications of third parties, which can be determined by means of statistical data.

Moreover, we have a lawful interest in making available pseudonymised data by INFOnline for purposes of developing and providing personalised advertising.

II. Types of data

INFOnline GmbH collects the following data, which according to GDPR is of a personal nature:

IP address: when connected to the internet, every device requires a distinct address, the so-called IP (Internet Protocol) address. Due to the internet’s functionality, it is essential that the IP address is saved, at least temporarily. Before processing, IP addresses are abridged and are also only processed anonymously. Unabridged IP addresses are neither saved nor processed.

A device identifier: to recognise individual devices, reach assessment uses the device’s distinct identification characteristics or a signature generated by various aspects of automatically transferred information of your device. Data measurement and subsequent identifier allocation might also be possible when using other applications that use INFOnline GmbH’s measurement process (“SZMnG”). The following distinct device characteristics can be transmitted to INFOnline GmbH by means of a hash code:



Vendor ID

III. Utilisation of data

The measuring method of INFOnline GmbH used in this application establishes usage data. This is done to establish the performance values of page impressions, visits and clients and to make use of them to establish further performance indicators (e.g. qualified clients). Furthermore, the measured data is utilised as follows:

A so-called geolocation, i.e. the allocation of a website visited to the location, is solely made on the basis of the anonymised IP address and the geographical level of federal states/regions. In no event, will the geographical data obtained in this manner allow any reference to the user’s specific place of residence.

A technical client’s (e.g. a browser on a device) usage data is collected on a cross-application basis and saved to a databank. This information is used to technically assess the socio-demographic parameters of age and gender and is then delivered to the AGOF’s service providers for further processing of reach values. Within the scope of the AGOF-Study, socio-demographic parameters are technically assessed on the basis of a random sample and can subsequently be allocated to the following categories: age, gender, nationality, occupation, marital status, general specifications regarding household, household income, place of residence, internet usage, online interests, location of use, user type.

IV. Duration of data storage

The unabridged IP address is not stored by INFOnline GmbH. The abridged IP address is stored for a maximum of 60 days. Usage data connected to the distinct identifier are stored for a maximum of 6 months.

V. Data transfer
