Privacy Policy

Effective Date: 17.03.2026

Introduction

I am committed to protecting the privacy of the visitors of my website. This privacy policy explains how I collect, use, share, and protect personal information in accordance with the General Data Protection Regulation (GDPR).

Liability for and Review of Content

My own content is to be distinguished from cross-references, i.e. links, to websites of other providers. These links only provide access for using third-party content in accordance with Section 7 of the German Digital Services Act (DDG). Prior to providing links to other websites, I review third-party content for potential civil or criminal liability. However, a continuous review of third-party content for changes is not possible and therefore I cannot accept any responsibility. For illegal, incorrect, or incomplete content, including any damage arising from the use or non-use of third-party information, liability rests solely with the provider of the website.

Access Data

When you visit the website, data regarding access to the website is stored in log files based on a legitimate interest (see Art. 6(1)(f) of the GDPR). The following data is logged:

Website visited
Time of access
Browser used
Operating system used
IP address used

Unless a more specific retention period is stated in this privacy policy, I will retain your personal data until the purpose for which it was collected no longer applies. If you submit a valid request for deletion or revoke your consent to data processing, your data will be deleted unless I have other legally permissible grounds for storing your personal data (e.g., retention periods under tax or commercial law); in the latter case, the data will be deleted once these grounds no longer apply. If data must be retained for evidentiary purposes, it is exempt from deletion until the incident has been definitively resolved.

Handling of Contact Information

If you contact me using the contact options provided, your information will be stored so that it can be accessed to process and respond to your inquiry. This data will not be shared with third parties without your consent.

User Rights

As a user, you have the right to request, free of charge, information about what personal data has been stored about you. You also have the right to have incorrect data corrected and to restrict the processing or erasure of your personal data. If applicable, you may also exercise your right to data portability. If you believe that your data has been processed unlawfully, you may file a complaint with the competent supervisory authority.

Right to Object

Users of this website may exercise their right to object and object to the processing of their personal data at any time. If you wish to request correction, blocking, deletion, or information regarding the personal data stored about you, or if you have questions regarding the collection, processing, or use of your personal data, or if you wish to revoke any consent you have given, please contact us at the email address provided above.
