The data protection notices and declarations of other providers apply to Internet pages of other providers to which reference is made, e.g. via links.

III. Handling of your data

III.1 Personenbezogene Daten und Grundsätze der Datennutzung

III.1 Personal data and principles of data use

According to Article 4 of the GDPR, personal data is any information relating to an identified or identifiable natural person. An identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.

This includes, for example, information such as your name, age, address, telephone number, date of birth, email address, IP address or user behaviour. Information for which I cannot (or can only with disproportionate effort) establish a link to your person, e.g. by anonymising the information, is not personal data.

The processing of personal data (e.g. collection, retrieval, use, storage or transmission) always requires a legal basis or your consent. Processed personal data will be deleted as soon as the purpose of the processing has been achieved and there are no longer any legally prescribed obligations to retain the data.

III.2 Specific processing operations

Usage data

With every access to the website and every request for a file stored on the website, the following non-personal access data is automatically logged. The storage serves internal system-related and statistical purposes.


The following data is automatically recorded in the server log files:

  • name of the retrieved file,
  • date and time of retrieval,
  • amount of data transferred,
  • information about successful retrieval,
  • web browser and
  • requesting domain.
  • In addition, the IP addresses of the requesting computers are logged.

For reasons of data security, i.e. to be able to detect unauthorised access or prevent misuse of the website, the complete IP address of the requesting computer is recorded, stored and automatically deleted within a defined period of time after the end of the access. The defined period for the server log files depends on the settings of the hosting provider and is usually seven to 60 days.

Use of cookies

Currently, no cookies are used.

Tracking and analytics tools

For statistical evaluation and optimisation of the website, I use the web analysis service software Matomo ( on this website. Since Matomo is installed on my own servers, no data is transmitted to servers that are outside of my control.

Matomo uses JavaScript, if you allow it in your browser settings, to display additional visitor configurations – operating system family used, screen resolution and plugins installed.


In addition, the web analysis software collects the data as listed in the server log files section. Your IP address is anonymised immediately; thus you remain anonymous as a user.

Matomo does not collect any data about you.

Matomo is configured so that it does not set a cookie.

I understand this analysis to be part of the internet service. I would like to use it to further improve the website and adapt it even more to the needs of the users.


If you subscribe to my newsletter, the data in the respective input mask will be transmitted to the person responsible for the processing. The registration for my newsletter takes place in a so-called double opt-in procedure. This means that you will receive an e-mail after registration in which you are asked to confirm your registration. This confirmation is necessary so that no one can register with other people's email addresses. When registering for the newsletter, the user's IP address and the date and time of registration are stored. This serves to prevent misuse of the services or the e-mail address of the person concerned. The data is not passed on to third parties. An exception exists if there is a legal obligation to pass on the data. The data is used exclusively for sending the newsletter. The subscription to the newsletter can be cancelled by the data subject at any time. Likewise, consent to the storage of personal data can be cancelled at any time. For this purpose, a corresponding link can be found in each newsletter. The legal basis for the processing of the data after the user has registered for the newsletter is Art. 6 para. 1 lit. a) GDPR if the user has given his consent. The legal basis for sending the newsletter as a result of the sale of goods or services is Article 7 (3) German Law against Unfair Competition.

Newsletter: Use of rapidmail

Description and purpose: I use rapidmail to send newsletters. The provider is rapidmail GmbH, Wentzingerstraße, 21, 79106 Freiburg, Germany. Among other things, rapidmail is used to organise and analyse the dispatch of newsletters. The data you enter for the purpose of receiving the newsletter is stored on rapidmail's servers in Germany. If you do not wish to have your data analysed by rapidmail, you must unsubscribe from the newsletter. For this purpose, I provide a corresponding link in every newsletter message. For the purpose of analysis, the emails sent with rapidmail contain a so-called tracking pixel, which connects to the servers of rapidmail when the email is opened. In this way, it can be determined whether a newsletter message has been opened. Furthermore, with the help of rapidmail, I can determine whether and which links in the newsletter message are clicked on. All links in the email are so-called tracking links, with which your clicks can be counted.

Newsletter: Legal basis: The legal basis for the data processing is Art. 6 para. 1 lit. a) GDPR.

Receiver: The recipient of the data is rapidmail GmbH.

Newsletter: Transfer to third countries: A transfer of data to third countries does not take place.

Newsletter: Duration: The data stored by me within the scope of your consent for the purpose of the newsletter will be stored by me until you unsubscribe from the newsletter and will be deleted from my servers as well as from the servers of rapidmail after you unsubscribe from the newsletter. Data stored by me for other purposes (e.g. e-mail addresses for a possible member area) remain unaffected by this.

Newsletter: revocation option: You have the option to revoke your consent to data processing with effect for the future at any time. The legality of the data processing operations already carried out remains unaffected by the revocation.

Newsletter: Further data protection information: For more details, please refer to the data security information of rapidmail at: For more information on the analysis functions of rapidmail, please refer to the following link:

Integration of external services

Currently, no external services, such as map services, are integrated.

Data privacy on social media profiles

I do not collect any personal data myself on the social media profiles on LinkedIN, Facebook, Instagram and Twitter. However, I would like to point out that when using social media services, you are subject to their respective data protection provisions and that data may be transferred to the services.

Collection of additional data

Any further and personal data will only be collected if you provide this information voluntarily, for example in the context of an enquiry or registration. The data is stored and used to process your request. The duration of the storage of the above-mentioned data depends on the background of your contact. Your data will be deleted regularly if the purpose of the communication no longer applies and storage is no longer necessary (e.g. after processing your request). For this purpose, you give your consent, for example, by contacting us.

III.3 Data security and backup actions

I guarantee to protect your privacy and to treat your personal data confidentially. In order to prevent manipulation, loss or misuse of your data stored with me, I take extensive technical and organisational security precautions, which are regularly checked and adapted to technological progress. However, I would like to point out that, due to the structure of the Internet, it is possible that the rules of data protection and the above-mentioned security measures are not observed by other persons or institutions not within my sphere of responsibility. In particular, data disclosed unencrypted – e.g. if this is done by e-mail – can be read by third parties. I have no technical influence on this. It is the responsibility of the user to protect the data provided by him/her against misuse by encrypting it or in any other way.

IV. Recipients or categories of recipients

As a rule, personal data that you provide to me will only be processed by me. However, in order to fulfill my contractual and legal obligations, it may be necessary for me to disclose the personal data stored about you to natural and legal persons, authorities, institutions or other bodies. In particular, the following categories of recipients come into consideration:

  • lawyers/courts for the assertion of legal claims and defence in legal disputes;
  • representatives for the guarantee of IT security and IT operation;
  • contractors;
  • other data recipients on the basis of consent given by you.
