The following overview summarizes the types of data processed and the purposes of their processing and refers to the data subjects.
Applicable Legal Basis under GDPR: Below you will find an overview of the legal basis of the GDPR on which we process personal data. Please note that in addition to the provisions of the GDPR, national data protection regulations may apply in your or our country of residence or domicile.
We take appropriate technical and organizational measures in accordance with legal requirements, taking into account the state of the art, implementation costs, and the nature, scope, circumstances, and purposes of processing, as well as the different probabilities of occurrence and the extent of the threat to the rights and freedoms of natural persons, to ensure a level of protection appropriate to the risk.
The measures include, in particular, securing the confidentiality, integrity, and availability of data by controlling physical and electronic access to the data as well as access, input, transmission, securing availability and their separation.
Securing online connections through TLS/SSL encryption technology (HTTPS): To protect user data transmitted via our online services from unauthorized access, we use TLS/SSL encryption technology. When a website is secured by an SSL/TLS certificate, this is indicated by the display of HTTPS in the URL.
Data processing in third countries: If we transfer data to a third country (i.e., outside the European Union (EU) or the European Economic Area (EEA)), this is always done in accordance with legal requirements.
For data transfers to the USA, we primarily rely on the Data Privacy Framework (DPF), which was recognized as a secure legal framework by an adequacy decision of the EU Commission dated July 10, 2023. Additionally, we have concluded Standard Contractual Clauses with the respective providers.
We delete personal data that we process in accordance with legal provisions as soon as the underlying consents are withdrawn or there are no further legal grounds for processing.
Retention and deletion of data: The following general periods apply for retention and archiving under German law:
As a data subject under the GDPR, you have various rights, particularly arising from Art. 15 to 21 GDPR:

Server log files may include the address and name of retrieved web pages and files, date and time of retrieval, transferred data volumes, notification of successful retrieval, browser type and version, user's operating system, referrer URL, and IP addresses.
When contacting us (e.g., via contact form, email, telephone, or social media), the information provided by the inquiring persons is processed to the extent necessary to respond to contact inquiries and any requested measures.

Web analytics serves to evaluate visitor flows to our online offer and may include behavior, interests, or demographic information about visitors as pseudonymous values. With the help of range analysis, we can recognize when our online offer is most frequently used.
Google Analytics: We use Google Analytics to measure and analyze the use of our online offer based on a pseudonymous user identification number. Google Analytics does not log and store individual IP addresses for EU users.
We integrate functional and content elements into our online offer that are obtained from the servers of their respective providers. This may include graphics, videos, or maps.
Google Fonts: We use Google Fonts for technically secure, maintenance-free, and efficient use of fonts. The provider of the fonts is informed of the user's IP address so that the fonts can be made available in the user's browser.
We ask you to regularly inform yourself about the content of our privacy policy. We adapt the privacy policy as soon as changes to the data processing we carry out make this necessary.
