Revocation of your consent to data processing

If you request the direct transfer of the data to another person, this will only be done as far as it is technically feasible.

SSL or TLS encryption

For security reasons and to protect the transmission of confidential content, such as requests that you send to the website, this site uses SSL or TLS encryption.

Newsletter data

To send a newsletter an e-mail address from you is needed. A verification of the specified e-mail address may be necessary and the receipt of the newsletter must be consented to. Supplementary data is not collected or is voluntary. The data is used exclusively for sending the newsletter.
The data provided during the newsletter registration will be processed exclusively on the basis of your consent (article 6 GDPR). A revocation of your already given consent is possible at any time. An informal notification by e-mail is sufficient for the revocation. The legality of the data processing operations already carried out remains unaffected by the revocation. Data entered to set up the subscription will be deleted in the event of unsubscription. If this data has been transmitted to us for other purposes and elsewhere, it will remain with us.

Plugins and embedded functionality as well as content

The website may integrate functional and content elements that are obtained from the servers of their respective providers (here referred to as "third-party providers"). These can be, for example, graphics, videos or social media posts (here uniformly referred to as "content"). The integration always requires that the third-party providers of this content processes the IP address of the user, since without the IP address they could not send the content to the browser of the user. The IP address is thus required for the display of this content or functionality.

Third-party providers may also use so-called pixel tags (invisible graphics, also known as "web beacons") for statistical or marketing purposes. These "pixel tags" can be used to analyze information such as visitor traffic on the pages of this website. This pseudonymous information may also be stored in cookies on the user's device and may contain, among other things, technical information about the browser and operating system, referring websites, time of visit and other information about the use of our online offer as well as be linked to such information from other sources.

Notes on legal basis: If the website asks for your consent for the use of third-party content, the legal basis for the processing of data is consent. Otherwise, your data is processed on the basis of legitimate interests in an appealing presentation of online offers within the meaning of article 6 GDPR. This includes usage data (e.g. websites visited, interest in content, access times), meta/communication data (e.g. device information, IP addresses) as well as content data (e.g. text input, photographs, videos).
