"For this purpose the following data: GAID / IDFA, IP address, location / time zone and locale settings (country and preferred language), carrier, operating system, network connection type and speed, device properties related to screen size and orientation, audio volume and battery, device memory usage, Internet browser user-agent used to access the services, device make, model and operating system are processed by us and such advertising partners."

The app collects granular device data including audio volume, battery level, device memory usage, screen orientation, and network speed — well beyond what is needed for a mobile app's core functionality — primarily for advertising purposes.

"When using the App, we collect the personal data described below to enable convenient use of the functions. If you want to use our App, we collect the following data, which is technically necessary for us to offer you the functions of our App and to guarantee stability and security: IP address, unique device ID, location, date and time of the request, time zone difference to Greenwich Mean Time (GMT)."

Location data is collected as supposedly 'technically necessary' and is also shared with advertising partners for personalized advertising, enabling location-based tracking and targeted ads.

"The third party providers and advertising partners named in this privacy policy engaged by us (Google, Facebook, AppLovin, Flurry/Oath, MoPub, Tapjoy, IronSource, inMobi, Vungle, Mytarget, Adcolony) may process data outside the EU/EEA. We (as well as third party providers engaged by us) also use the information collected, including your personal data, for the purpose of marketing and improving our Apps."

User data is shared with over a dozen third-party advertising and analytics providers including Tenjin, Unity, Google Firebase, Flurry Analytics, and Facebook Analytics, many of which process data outside the EU/EEA with varying levels of data protection.

"We as well as our advertising partners use the identifier to provide you with personalized advertising and to evaluate your use. If you use Social Media on several end devices, a cross device analysis of the data can take place. The data collected through such identifier is not linked to any other device-related information."

The policy explicitly acknowledges cross-device tracking and analysis of user data, particularly through Facebook's Page Insights and advertising identifiers, enabling unified user profiles across multiple devices.

"We reserve the right to change the regulations of this privacy policy at any time, taking into account applicable laws and data protection provisions."

The company reserves the right to change the privacy policy at any time without requiring explicit user consent or providing meaningful advance notice beyond making it accessible in the app settings.

"In the case of long-term contractual relationships, such as the use of our App, these storage periods may vary, but are generally limited to the duration of the contractual relationship or, with regard to the inventory data, to the maximum legal retention periods (e.g. in accordance with the German Commercial Code and the Tax Code). Criteria for the storage period include whether the data are still up-to-date, whether the contractual relationship with us still exists, whether an inquiry has already been processed."

Retention periods are described in vague terms with no specific timelines. Data may be kept for the entire duration of the 'contractual relationship' (i.e., as long as you have the app) plus undefined legal retention periods, with multiple subjective criteria that could justify extended retention.

"You may delete and change entered data any time via message to [email protected]. Your profile and account data are deleted after you deleted such data in your App account or deleted the entire account via the respective button in the App, which is more or less immediately after such deletion according to our deletion routines."

While there is an in-app delete button, changing data requires emailing support, and the deletion timeline is described vaguely as 'more or less immediately' with no firm guarantee, leaving ambiguity about complete data removal.
