  1. Data collection on our website


The internet pages partly use so-called cookies. Cookies do not cause any damage to your computer and do not contain viruses. Cookies serve to make my offer more user-friendly, more effective and safer. Cookies are small text files that are stored on your computer and saved by your browser.

Most of the cookies I 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. These cookies allow me to recognize your browser on your next visit.

You can set your browser so that you are informed about the setting of cookies and allow cookies only in individual cases, exclude the acceptance of cookies for certain cases or in general and activate the automatic deletion of cookies when closing the browser. If cookies are deactivated, the functionality of this website may be limited.

Cookies that are required to carry out the electronic communication process or to provide certain functions you have requested (e.g. shopping cart function) are stored on the basis of Art. 6 (1) lit. f DSGVO. The website operator has a legitimate interest in storing cookies for the technically error-free and optimized provision of its services. Insofar as other cookies (e.g. cookies for the analysis of your surfing behavior) are stored, these are treated separately in this data protection declaration.


When visiting the website (server log files)

The provider of the pages automatically collects and stores information in so-called server log files, which your browser automatically transmits to me. These are:

  • browser type and browser version
  • operating system used
  • referrer URL
  • Hostname of the accessing computer
  • Time of the server request
  • IP address

This data is not merged with other data sources.

The collection of this data is based on Art. 6 para. 1 lit. f DSGVO. The website operator has a legitimate interest in the technically error-free presentation and optimization of its website – for this purpose, the server log files must be collected.

Contact form

If you send me inquiries via contact form, your data from the inquiry form, including the contact data you provided there, will be stored by me for the purpose of processing the inquiry and in case of follow-up questions. I do not pass on this data without your consent.

The processing of the data entered in the contact form is therefore based exclusively on your consent (Art. 6 para. 1 lit. a DSGVO). You can revoke this consent at any time. For this purpose, an informal communication by e-mail to me is sufficient. The legality of the data processing operations carried out until the revocation remains unaffected by the revocation.

The data you entered in the contact form will remain with me until you request me to delete it, revoke your consent to store it or the purpose for storing the data no longer applies (e.g. after processing your request has been completed). Mandatory legal provisions – in particular retention periods – remain unaffected.

Inquiry by e-mail or telephone

If you contact me by e-mail or telephone, your inquiry including all resulting personal data (name, inquiry) will be stored and processed by me for the purpose of processing your request. I will not pass on this data without your consent.

The processing of this data is based on Art. 6 (1) lit. b DSGVO, if your request is related to the performance of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, the processing is based on your consent (Art. 6 para. 1 lit. a DSGVO) and/or on my legitimate interests (Art. 6 para. 1 lit. f DSGVO), as I have a legitimate interest in the effective processing of requests addressed to me.

The data you send to me via contact requests will remain with me until you ask me to delete it, revoke your consent to store it, or the purpose for storing the data no longer applies (e.g. after your request has been processed). Mandatory legal provisions – in particular legal retention periods – remain unaffected.

Processing of data (customer and contract data)

I collect, process and use personal data only to the extent that they are necessary for the establishment, content or modification of the legal relationship (inventory data). This is done on the basis of Art. 6 (1) lit. b DSGVO, which permits the processing of data for the performance of a contract or pre-contractual measures. I collect, process and use personal data about the use of our Internet pages (usage data) only to the extent necessary to enable the user to use the service or to bill the user.

The collected customer data will be deleted after completion of the order or termination of the business relationship. Legal retention periods remain unaffected.

  1. Use of Google Analytics

I use Google Analytics, a web analytics service provided by Google Inc, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA. Google Analytics uses “cookies”, which are text files placed on your computer, to help the website analyze how users use the site. The information generated by the cookie about your use of this website is usually transmitted to a Google server in the USA and stored there. In the event that IP anonymization is activated on this website, however, your IP address will be truncated beforehand by Google within member states of the European Union or in other contracting states to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA and shortened there. On our behalf, Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity and providing other services relating to website activity and internet usage. The IP address transmitted by your browser as part of Google Analytics will not be merged with other data from Google. You may refuse the use of cookies by selecting the appropriate settings on your browser, however please note that if you do this you may not be able to use the full functionality of this website. You can also prevent the collection of data generated by the cookie and related to your use of the website (including your IP address) to Google and the processing of this data by Google, by downloading and installing the browser plugin available at the following link ( I would like to point out that on this website Google Analytics has been extended by the code “gat._anonymizeIp();” to ensure anonymized collection of IP addresses (so-called IP masking). In addition, you can prevent Google Analytics from collecting data by clicking on the following link. An opt-out cookie will then be set, which prevents the further collection of your data when visiting this website. This procedure is particularly recommended when accessing our site via mobile devices. For more information on terms of use and data protection, please visit or We base the use of the aforementioned analysis tool on Art. 6 (1) (f) DSGVO: the processing is carried out to analyze user behavior and is therefore necessary to protect my legitimate interests.

  1. Use of Hotjar

My website uses Hotjar to collect information about the behavior of my users and about their end devices (e.g. IP address in anonymized form, device type, browser type, preferred language, etc). Hotjar stores this information in a pseudonymized user profile. The information is not used to identify a user. You can object to the storage of the user profile and the information about your visit to my website and the setting of Hotjar tracking cookies. For more information, please see this link and Hotjar’s privacy policy at

  1. Embedded YouTube videos

On some of my websites I embed YouTube videos. The operator of the corresponding plugins is YouTube, LLC, 901 Cherry Ave, San Bruno, CA 94066, USA. When you visit a page with the YouTube plugin, a connection to YouTube servers is established. This tells Youtube which pages you are visiting. If you are logged into your Youtube account, Youtube can assign your surfing behavior to you personally. You can prevent this by logging out of your Youtube account beforehand. If a Youtube video is started, the provider uses cookies that collect information about user behavior. If you have deactivated the saving of cookies for the Google Ad program, you will not have to deal with such cookies when watching Youtube videos. However, Youtube also stores non-personal usage information in other cookies. If you would like to prevent this, you must block the storage of cookies in the browser. Further information on data protection at “Youtube” can be found in the provider’s privacy policy at:

  1. Deletion or blocking of data

I adhere to the principles of data avoidance and data economy. I therefore store your personal data only as long as is necessary to achieve the purposes stated here or as provided for by the legislator’s various storage periods, After the respective purpose ceases to exist or these periods expire, the corresponding data will be routinely blocked or deleted in accordance with the statutory provisions.

  1. Transfer of data

A transfer of your personal data to third parties for purposes other than those listed below does not take place. I will only pass on your personal data to third parties if:

– you have given your explicit consent according to Art. 6 para.1 lit.a DSGVO,

– the transfer is necessary according to Art.6 Abs.1 lit.f DSGVO and there is no reason to assume that you have an overriding interest worthy of protection in the non-disclosure of your data,

– in the event that there is a legal obligation for the disclosure in accordance with Art. 6 Para.1 lit.c DSGVO, as well as

– this is legally permissible and necessary according to Art. 6 para.1 lit.b DSGVO for the processing of contractual relationships with you.

You are entitled to the following data subject rights:

a. Right to information

You have the right to request confirmation from me as to whether personal data concerning you is being processed.

d. Right of withdrawal

You have the right to revoke your consent at any time. The revocation of consent does not affect the lawfulness of the processing carried out on the basis of the consent until the revocation.

f. Right of appeal

  1. Change of our privacy policy

I reserve the right to occasionally adapt this privacy policy so that it always complies with the current legal requirements or to implement changes to my services in the privacy policy, e.g. when introducing new services. The new privacy policy will then apply to your next visit.
