Purposes of data processing by the responsible body and third parties

I process your personal data only for the purposes stated in this privacy policy. A transfer of your personal data to third parties for purposes other than those mentioned does not take place. I only share your personal information with third parties if:

  • You have given your explicit consent,
  • the processing is required to execute a contract with you,
  • the processing is necessary to fulfill a legal obligation,
  • processing is necessary to protect legitimate interests and there is no reason to believe that you have an overriding legitimate interest in not disclosing your information.

Submitting data

Synchronization / Backup

All data in my apps are stored primarily on the respective mobile device. Only when using the synchronization function the data will be transferred via the internet to Google Drive servers and from there to the connected devices. When using Google Drive, the Privacy Policy of Google takes effect.

Advertising and in-app purchases

I use AdMob Google Inc for ads and Google In-app Billing Service for in-app purchases. The data processing takes place on the basis of the legal regulations of the article 6, paragraph 1, point a) and f) of the GDPR. My concern within the meaning of the GDPR (legitimate interest) is the maintenance of the offer and my apps. I have no influence on the collection of personal data from Google Inc. Here the Privacy Policy of Google takes effect.

Analytics and Crash Reporting (Firebase)

For my apps I use technologies from Google Firebase (Google Inc). Firebase is part of the Google Cloud Platform and offers many services to developers. A list can be found here:

Some Firebase services process personal information. In most cases, the personal data is limited to so-called “instance IDs” that are time-stamped. Firebase’s Instance IDs are unique, allowing you to link different events or processes. These data are neither personally identifiable information nor do I make any effort to personalize them later. I use this aggregated data to analyze and optimize usage behavior, for example by analyzing crash reports.

In addition to the “Instance ID” described above, Google also uses the advertising ID of the device for Firebase Analytics. In the device settings of your mobile device you can limit the use of the advertising ID.
Android: Settings > Google > Ads > Reset advertising ID

In addition, you always have the option to disable tracking by Firebase Analytics and Firebase Crashlytics in the app. Just disable the following two switches:

  • Settings > Other  > Activate analytics
  • Settings > Other > Activate crash reporting

If you have questions of any kind and you contact me, for example, by e-mail, telephone or contact form, you give me for the purpose of establishing contact your voluntary consent. This requires, among other things, the specification of a valid e-mail address. This serves for the assignment of the request and the subsequent answering of the same. The information you provide will be processed and stored permanently for the purpose of processing the request and for possible follow-up questions. You can revoke your consent at any time for the future by e-mail (

Change of my privacy policy

I reserve the right to amend this privacy policy to always comply with the latest legal requirements or to implement changes to my services in the privacy policy, e.g. when introducing new services. Your new visit will be subject to the new privacy policy.
