privacy policy

The protection of your personal data is important to us. We therefore process your data exclusively on the basis of the statutory provisions (GDPR).


If you contact us by e-mail, the data you provide will be stored for six months for the purpose of processing your enquiry and in case of follow-up questions. We will not pass this data on to third parties without your consent.

Data storage

We store the following data in order to prepare cost estimates and preliminary discussions: Name, address, telephone number, e-mail address. If no contractual relationship is established, this data is deleted after a period of one year. If a contractual relationship is established, it is possible that further data will have to be stored for the purpose of fulfilling the order. This data provided by you is necessary for the fulfilment of the contract or for the implementation of pre-contractual measures. Without this data, the processing of your order is not possible. Furthermore, your data will be passed on to a tax consultant for the fulfilment of our obligations under tax law. Unless otherwise agreed with you, the stored data will be deleted after fulfilment of the contract, unless a subsequent contractual relationship is established. All data required for invoicing purposes will be stored until the expiry of the retention period under tax law (7 years).

Data collection on the website

When you visit the website, data is collected by our IT systems. The web servers generate log files which contain the following information:

  • the pages accessed (URL)
  • the browser or browser version
  • the operating system used
  • the referrer URL (the previously visited page)
  • host name and IP address of the accessing computer
  • the time of the server request

This data is collected automatically as soon as you enter our website and is necessary for reasons of operational security, to compile access statistics or to detect errors. The IP is anonymised and can therefore no longer be assigned to your visit to our website.


Our website uses cookies. Cookies are text files that are placed and stored on a computer system via an internet browser.

Numerous websites and servers use cookies. Many cookies contain a so-called cookie ID. A cookie ID is a unique identifier of the cookie. It consists of a string of characters by which Internet pages and servers can be assigned to the specific Internet browser in which the cookie was stored. This enables the visited Internet pages and servers to distinguish the individual browser of the data subject from other Internet browsers that contain other cookies. A specific internet browser can be recognised and identified via the unique cookie ID.

Through the use of cookies, we can provide the users of this website with more user-friendly services that would not be possible without cookies.

By means of a cookie, the information and offers on our website can be optimised in the interests of the user. Cookies enable us to recognise the users of our website. The purpose of this recognition is to make it easier for users to use our website. For example, the user of a website that uses cookies does not have to re-enter his or her access data each time he or she visits the website because this is handled by the website and the cookie stored on the user's computer system. Another example is the cookie of a shopping basket in the online shop. The online shop remembers the items that a customer has placed in the virtual shopping basket via a cookie.

The data subject can prevent the setting of cookies by our website at any time by means of an appropriate setting of the Internet browser used and thus permanently object to the setting of cookies. Furthermore, cookies that have already been set can be deleted at any time via an internet browser or other software programmes. This is possible in all common internet browsers. If the data subject deactivates the setting of cookies in the Internet browser used, it may no longer be possible to fully use all the functions of our website.

Your rights

In principle, you have the rights to information, correction, deletion, restriction, data transferability, revocation and objection. We will respond to your requests in this regard within two weeks.
