Objective and basic information on data processing

This privacy policy explains the nature, scope and purpose of the processing of personal data within our online offering and the websites, functions and content associated with it. The privacy policy applies regardless of the domains, systems, platforms and devices (e.g. desktop or mobile) on which the online offer is executed.

We process personal data of our users only in compliance with the relevant data protection provisions in accordance with the principles of data economy and data avoidance. It follows that the processing of personal data of our users regularly takes place only after the consent of the user. An exception applies in those cases in which the processing of the data is permitted by legal regulations.

We take organizational, contractual and technical security measures in accordance with the state of the art to ensure that the provisions of data protection laws are complied with and thus to protect the data processed by us against accidental or intentional manipulation, loss, destruction or against access by unauthorized persons.

If content, tools or other means of third-party providers (e.g. YouTube videos) are used within the scope of our online offer and their named registered office is abroad, it is to be assumed that a data transfer to the registered office states of the third-party providers takes place.


For the purposes of this Privacy Policy, the term:

„User“ means all customers and visitors to our Website, which term shall be understood to be gender-neutral;

  • „Website or Online Offer“ means, on an overarching basis, the content and functions contained on our Website and connected to the Website;
  • „Third-party providers“ other providers that are different from us, whose content, tools or other means we use as part of our online offering and whose named registered office may be abroad. For example, video platforms such as YouTube are to be mentioned here.

Data processing

1. Provision of the blog and creation of logfiles

With every call and every use of this blog, data and information are collected. This data and information is stored in log files of the server.


  • IP address
  • Information about the browser type and version used
  • Date and time of access
  • Internet service provider of the user
  • Operating system of the user
  • Websites from which the user’s system accesses our website
  • Web pages that are called up by the user’s system via our website

The legal basis for the temporary storage of the data and the log files is Art. 6 Para. 1 e GDPR, i.V.m. § 4 HmDSG i.V.m. § 3 und 4 HmbHG..

The temporary storage of the IP address by the system is necessary to enable delivery of the website to the user’s computer. For this purpose, the user’s IP address must remain stored for the duration of the session.

Log files are stored to ensure the functionality of the website, to optimize the content of the website and to ensure the security of our information technology systems.

The data is deleted as soon as it is no longer required to achieve the purpose for which it was collected. In the case of the collection of data for the provision of the website, this is the case when the respective session has ended.

In the case of storage of data in log files, this is the case after 28 days at the latest. If the data is stored beyond this period, the IP addresses of the users are deleted or alienated so that it is no longer possible to assign the calling client.

The personal data will also be processed for the following purposes if there is a legal basis for doing so:

  • the provision, execution, maintenance, optimization and safeguarding of our services, services and user services;
  • ensuring effective customer service and technical support.

When a user accesses a website, a cookie may be stored on the user’s operating system. This cookie contains a characteristic string of characters that allows the browser to be uniquely identified when the website is accessed again. Most of the cookies we use are so-called „session cookies“. They are automatically deleted after the end of your visit. Other cookies remain stored on your terminal device until you delete them.

3. SSL or TLS encryption

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

You can recognize an encrypted connection by the fact that the address line of the browser changes from „http://“ to „https://“ and by the lock symbol in your browser line. If SSL or TLS encryption is activated, the data you transmit to us cannot be read by third parties.

4. Contact form and e-mail contact

For the processing of the data, the consent of the user is obtained during the submission process and reference is made to this privacy policy.

Disclosure of data to third parties

1. Social media

YouTube with enhanced privacy

We use services of the provider YouTube for the integration of videos. YouTube is operated by YouTube LLC, 901 Cherry Avenue, San Bruno, CA 94066, USA. YouTube is represented by Google LLC. with headquarters at 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.

Clicking on „Activate video“ embeds an iframe with the provider’s content into the page. No content from the services is embedded or data is transferred before the user clicks.

When you activate the content, the operator of the social media platform receives the information that the respective page has been accessed, and personal data is also transmitted to the operator of the platform.

The legal basis for the processing of the data is Art. 6 para. 1 lit. a GDPR.

By using YouTube, information about your use of this website (including your IP address) may be transmitted to and stored by YouTube (Google) on servers in the United States.
