VI. Information on data processing

Your data processed when using our website will be deleted or blocked as soon as the purpose of storage no longer applies, the deletion of the data does not conflict with any statutory retention requirements and no other information on individual processing methods is given below.

Server data

For technical reasons, in particular to ensure a secure and stable website, your internet browser transmits data to us or to our web space provider. These so-called server log files record, among other things, the type and version of your Internet browser, the operating system, the website from which you switched to our website (referrer URL), the website (s) of our website that you are visiting, the date and time of the respective access as well as the IP address of the internet connection from which our website is used.


This data collected in this way is temporarily stored, but not together with other data from you.

This storage takes place on the legal basis of Art. 6 Para. 1 lit.f) GDPR. Our legitimate interest lies in the improvement, stability, functionality and security of our website.

The data will be deleted after seven days at the latest, unless further storage is required for evidence purposes. Otherwise, the data will be wholly or partially excluded from deletion until an incident has been finally clarified.


a) Session cookies / session cookies

We use so-called cookies on our website. Cookies are small text files or other storage technologies that are stored and stored on your device by the internet browser you use. These cookies process certain information about you on an individual basis, such as your browser or location data or your IP address. 

This processing makes our website more user-friendly, more effective and safer, as the processing enables, for example, the reproduction of our website in different languages or the offer of a shopping cart function.

The legal basis for this processing is Art. 6 Paragraph 1 lit b.) GDPR, provided that these cookies are used to process data to initiate or process contracts.

If the processing does not serve to initiate or process a contract, our legitimate interest lies in improving the functionality of our website. The legal basis is then Article 6 (1) (f) GDPR.

When you close your internet browser, these session cookies are deleted.


b) Third party cookies

Our website may also use cookies from partner companies with whom I work for the purpose of advertising, analysis or the functionalities of our website.

Please refer to the following information for details on this, in particular on the purposes and legal basis for processing such third-party cookies.


c) possibility of elimination

You can prevent or restrict the installation of cookies by setting your internet browser. You can also delete cookies that have already been saved at any time. The steps and measures required for this, however, depend on the specific Internet browser you are using. If you have any questions, please use the help function or documentation of your Internet browser or contact its manufacturer or support. In the case of so-called flash cookies, however, processing cannot be prevented via the browser settings. Instead, you have to change the setting of your Flash player. The steps and measures required for this also depend on the specific Flash player you are using. If you have any questions, please use the help function or documentation of your Flash player or contact the manufacturer or user support.

However, should you prevent or restrict the installation of cookies, this may mean that not all functions of our website can be used to their full extent.  


Contact inquiries / contact options

If you contact us via the contact form or email, the data you provide will be used to process your request. The specification of the data is necessary for processing and answering your request - without this provision we cannot answer your request, or at most only to a limited extent.

The legal basis for this processing is Article 6 (1) lit. b) GDPR.

Your data will be deleted if your request has been finally answered and the deletion does not conflict with any statutory retention requirements, e.g. in the event of a subsequent contract processing.

User contributions, comments and ratings

We offer you the opportunity to post questions, answers, opinions or ratings, hereinafter referred to as “contributions”, on my website. If you take advantage of this offer, we will process and publish your contribution, the date and time of submission and the pseudonym you may have used.


The legal basis for this is Article 6 (1) (a) GDPR. You can revoke your consent at any time with effect for the future in accordance with Art. 7 Para. 3 GDPR. All you have to do is inform us of your revocation.

In addition, I also process your IP and email address. The IP address is processed because we have a legitimate interest in initiating or supporting further steps if your contribution encroaches on the rights of third parties and / or it is otherwise unlawful.

In this case, the legal basis is Article 6 (1) (f) GDPR. Our legitimate interest lies in the legal defense that may be necessary.


Google Analytics

We use Google Analytics on our website. This is a web analysis service provided by Google LLC, 1600 Amphitheater Parkway, Mountain View, CA 94043 USA, hereinafter referred to as “Google”.

Through the certification according to the EU-US data protection shield ("EU-US Privacy Shield")

Google guarantees that the EU's data protection requirements will also be complied with when processing data in the USA.

The Google Analytics service is used to analyze the usage behavior of our website. The legal basis is Art. 6 Paragraph 1 lit.f) GDPR. Our legitimate interest lies in the analysis, optimization and economic operation of our website.

Usage and user-related information, such as IP address, location, time or frequency of visits to our website, are transmitted to a Google server in the USA and stored there. However, we use Google Analytics with the so-called anonymization function. With this function, Google shortens the IP address within the EU or the EEA.

The data collected in this way is in turn used by Google to provide us with an evaluation of the visit to our website and of the usage activities there. This data can also be used to provide other services related to the use of our website and the use of the Internet.

Google states that it will not associate your IP address with other data. In addition, Google maintains

Further data protection information is available for you, for example also on the possibilities of preventing the use of data.

Google also offers

a so-called deactivation add-on along with further information on this. This add-on can be installed with common internet browsers and offers you further control over the data that Google collects when you visit my website. The add-on informs the JavaScript (ga.js) of Google Analytics that information about visiting our website should not be transmitted to Google Analytics. However, this does not prevent information from being transmitted to me or to other web analysis services. You can of course also find out in this data protection declaration whether and which other web analysis services are used by us.

Google Maps

We use Google Maps on our website to show our location and to create directions. This is a service provided by Google LLC, 1600 Amphitheater Parkway, Mountain View, CA 94043 USA, hereinafter referred to as “Google”.

Through the certification according to the EU-US data protection shield ("EU-US Privacy Shield")

Google guarantees that the EU's data protection requirements will also be complied with when processing data in the USA.

In order to enable the display of certain fonts on our website, a connection to the Google server in the USA is established when our website is accessed.

If you call up the Google Maps component integrated in our website, Google saves a cookie on your device via your internet browser. Your user settings and data are processed in order to display your location and to create directions. I cannot rule out that Google uses servers in the USA.

The legal basis is Art. 6 Paragraph 1 lit.f) GDPR. Our legitimate interest lies in optimizing the functionality of our website.

Through the connection to Google established in this way, Google can determine from which website your request was sent and to which IP address the directions are to be sent.

If you do not agree to this processing, you have the option of preventing the installation of cookies by making the appropriate settings in your Internet browser. You can find details on this under the heading "Cookies" above.

In addition, Google Maps and the information obtained via Google Maps are used according to the  Google Terms of Service 

and the  Terms and Conditions for Google Maps

In addition, Google offers under

further information.

Use of script libraries (Google Web Fonts)

So that our content is displayed correctly and graphically appealing in every browser, we use script and font libraries such as Google Web Fonts ( ) for this website. Google Web Fonts are transferred to your browser's cache so that they only have to be loaded once. If your browser does not support Google Web Fonts or denies access, the content will be displayed in a standard font.  


When calling up script or font libraries, a connection to the library operator is automatically established. There is theoretically the possibility for this operator to collect data. It is currently not known whether and for what purpose the operators of the relevant libraries actually collect data.


Collection of data by third parties

This policy only addresses the use and disclosure of information that we collect from you. If you publish data on other websites or disclose it to third parties on the Internet, different provisions may apply. Therefore, always read the terms and conditions and data protection provisions carefully when disclosing data.  


This privacy policy does not apply to the business practices of companies that we do not own or control, or any person other than our employees and collaborators, including third parties, to whom we disclose this information as described in this privacy policy.  

How do I protect your data?

I take great care in implementing the security measures on the website and protect your data. I use industry-standard procedures and guidelines to ensure the protection of the information we collect and store, and to prevent unauthorized use of such information. I also require third parties to adhere to similar security requirements in accordance with this privacy policy. Although I take reasonable steps to protect data, I cannot be held responsible for the actions of those who have gained unauthorized access to my website or who misuse it, and I make no express or implied warranty that I will have such access can prevent.


Transfer of data outside of the European Economic Area 

Note that some recipients may not be based in the European Economic Area. If this is the case, I will only transfer your data to countries approved by the European Commission with an adequate level of data protection or to ensure an adequate level of data protection by means of a legal agreement.


Corporate transaction

I can pass on data in the event of a corporate transaction (e.g. the sale of significant parts of the company, a merger, a consolidation or a sale of assets). If one of the above-mentioned cases occurs, the acquirer or the corresponding company assumes the rights and obligations set out in this data protection declaration.



The protection of children's data is very important, especially in the online area. The website is not designed for and is not aimed at children. The use of our services by minors is only permitted with the prior consent or authorization of a parent or legal guardian. We do not knowingly collect personal information from minors. If a parent or legal guardian learns that his or her child has provided us with personal information without their consent, he / she can contact  contact us.
