The information on this website has been carefully collected. Yet, I take care that the information transmitted to you does not involve any legal infringements. Should any content on my website or in links be known to you implying legal infringements, I may kindly ask you to instantly notify me for the respective content to be removed.

The content of this website respects the copyright law and is placed at the disposal of internet users solely for private use. Every use beyond that purpose is not admissible.

Privacy Policy

Data Protection

As a pianist, I take seriously the protection of confidential information. Visiting my website, you leave – even if you might not be aware if it – tracks in the form of digital data. In this data protection policy, I would like to elucidate which data these are and how I implement the legal regulations of data protection.

Principally, my website is pure informative, i.e. you can surf on it without having to give any personal details. You find no contact form and you do not have to tell me who you are and why you visit my site. Should you have a request, please feel free to contact me via email.


Cookies are small text files saved to your device by your browser when you surf in the internet. The so-called “sessions-cookies” are deleted when you leave my website. Other cookies, e.g. of a third party, remain stored on your computer.

The settings of your browser allow you to decide if you want to accept cookies or not, or if the browser shall automatically delete the cookies after surfing. If you deactivate the utilization of cookies, there might be functional restrictions while using my website.

You can delete cookies from your computer without any risk by finding the cookie folder with the search function of your operating system and deleting all files in it, or by using an Internet Privacy Software which does that for you.

Access Data (Server Log-Files)

My website is hosted on a virtual server of Host Europe. This is a company offering since 1997 various products in the field of web hosting and cloud services. On April 2017, GoDaddy Inc. has announced its final takeover of Host Europe. Host Europe collects and saves data in so-called Log-Files, i.e. in the form of automated protocols which grasp certain services on the server.

Among these access data are the IP address of the user, the time of the access including the time zone, the notification of a successful or unsuccessful call, the name and version of your browser, your operating system and the referrer URL of the page visited.

These data are archived and will be deleted after a certain period. The so-called access-Log-Files are removed after 60 days, all other Log-Files after 7 days. The page of the provider gives you further details.

I do not use these Log-Files to find out your identity, and I do not combine them with other data. I reserve the right to additionally check these Server-Log-Files, should there be concrete evidence of an illicit use.

Tool of Analysis: Google Analytics

To optimize my web portal and to design it favorably for my clients, I consult the well-known Web analysis service Google Analytics by Google Inc., 1600 Amphitheatre Parkway Mountain View, CA 94043, USA.

This program helps me to understand how you and other visitors use my website. It utilizes certain “cookies”, i.e. text files which are stored on your computer to gather information about your surf behavior. The data produced by the cookie about your use of my website (including your IP address) are transmitted to a server of Google in the US and stored there. Google needs this information to analyze your use of my website, to provide me with reports about your web activities, and to offer further services related to your use of the website and the internet. It cannot be excluded that Google hands over this information to a third party. However, Google has assured that it will not associate your IP address with other data of Google.

Below, I will specify what I have done to optimize your data protection and which possibilities you have to prevent the data transfer to Google.

IP Anonymization

A use of Google Analytics, concurring with data protection necessities, requires the activation of the IP anonymizing function by means of an adapted tracking code. This has been achieved on all pages of my web portal. Before your data are transferred to the US, your IP address will be shortened inside the members of the European Union or other states of the European Economic Area. Yet, Google reserves the right to transfer, in a special case, the full IP address to an own server in the US before shortening it there.

Browser Add-On

As shown above, you can prevent data being collected and saved by cookies by deleting the existing cookies and by deactivating the storage of cookies in the settings of your browser. This can lead to functional restrictions while using my website. Google offers the download of a Browser Add-On to deactivate Google Analytics. It is available for all relevant browsers (i.e. Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, Apple Safari and Opera). If you install this Add-On, you prevent that the data obtained by cookies about you (including your IP address) will be transferred to Google and further processed there.

Objection against the Collection of Data

As the Browser Add-On does not work on every device, you can realize your right to object the data collection by Google by clicking onto the link at the end of this paragraph. This will set a so-called Opt-Out cookie which prevents the collection of your data when again visiting my website. I recommend declaring this objection against the data usage of Google on all of your systems, thus preventing an inter-device assignment of your use with your Google User-ID: Deactivate Google Analytics.

Contract of Data Processing

I have signed a contract with Google Inc. regulating the processing of data and I have consented to the supplement regarding data processing in my account settings of Google Analytics. I thereby fulfill the guidelines of the German Data Protection Administration when using Google Analytics.

Demographic Features

On my website, I have enabled the function “Demographics and Interests reports” of Google Analytics. Additional access data will be collected, e.g. the age, sex and special interests of my site visitors. These data are taken from Google’s Advertising or visiting data of third parties. They can, however, not be assigned to a certain person.

You can prevent the transfer of demographic features in two ways. You can simply deactivate this function in the display settings of Google. Here you find an instruction. You can, however, principally object to any collection of your data by Google Analytics if, on all of your devices used to surf the internet, you click onto the following link, thus setting the Opt-Out Cookie: Deactivate Google Analytics.

Privacy Policy of Google Analytics.

The following link will retrieve the Privacy Policy of Google Analytics. By using my website, you initially agree with the collection and usage of data about you by Google Analytics in the way described there. You have however, as I have shown to you, the option to object to this capturing of data, i.e. you can prevent Google from collecting or employing information about you. Simply click onto the link: Deactivate Google Analytics.

SSL Encryption

While visiting my website, you will notice that all pages are securely encrypted and transmitted via the SSL-protocol. You can verify this by the fact that the address of these pages starts with https:// and not http://. You will also detect a green lock in front of the address line. When you click onto it, you can have a look at the kind and duration of the certificate. All the data which you transfer to me while surfing are thus protected and cannot be read (deciphered) by a third party.

Your Right to the Information, Blocking and Deletion of Data

The federal law of data protection gives you the right to inform yourself about the collection and processing of your personal data without any costs. You also have the right to have these data corrected, made unavailable to users, or deleted. You can further object an approval at any time. Just refer to me under the contact data provided in the impressum above.

Modification of Privacy Policy

I reserve the right to adapt this privacy policy in case of changes of my website, a new legal position or other necessities. The actual version will always be displayed on this Web page. I may ask you to regularly consult the content of this privacy policy.
