Information on Data Protection

We place particular value on the protection of your personal data. We want you to know when we collect which of your data and how we use it.

1. Personal data

We only collect, process and use your personal data with your consent or if this is permitted through a legal provision. We only collect, process and use the personal data required for the execution of and mobilization of our services or those which you provide voluntarily for us.
Personal data is all data containing information on personal or material circumstances attributed to an identified or identifiable natural person. This includes, for example, name, Email address, postal address or telephone number.

We act according to the principle of data minimisation and data avoidance. Accordingly, we only collect as much personal data when you visit our website as is absolutely necessary. We collect, process and use this data exclusively in accordance with the provisions of the German Data Protection Act.

Data which we have collected on our websites will at no time be transmitted to any third party.

2. Collection and processing of data by means of cookies on visiting our website

Cookies are small text files stored on the user’s computer when visiting a website. They enable us to analyse your use of our website or to optimise access to our websites (e.g. to adapt the width of the websites to your computer screen). They do not contain any personal data.

We do not use cookies unless you have expressly agreed to this on our start page.

Cookies store every access to our Internet services under in a protocol file. The following data is stored there:

  • IP address of the requesting computer
  • Type of request
  • Date and time of request
  • Duration of stay
  • Entry pages
  • Exit pages
  • The requesting computer’s browser and plug-ins used
  • Search engines used
  • Search terms used
  • The operating system on the requesting computer
  • The language used
  • The volume of data transmitted
  • Visitors listed according to their countries of origin
  • Drop-out rate

We do not forward this usage data to any third party. Instead of this, we merely evaluate it for statistical purposes as soon as the data is no longer technically required. During this process, the data is anonymised and then deleted. The data is only combined with other data sources in the case described in paragraph 4 of this Information on Data Protection.

Most of the cookies we use are so-called “session cookies”, which are automatically deleted from your computer after your visit. Cookies do not cause any damage to your computer and do not contain any viruses.

3. Using the PIWIK analysis service

Our website uses PIWIK – a so-called web analysis service - for evaluating user access. PIWIK uses cookies according to clause 3. If you agree to the installation of the PIWIK cookie on our start page, the usage information generated by the cookie for analysis of the use of our websites (including your anonymised IP address) will be transmitted to our server and will be stored for usage analysis purposes. This primarily helps to optimise our website. Your IP address is immediately anonymised, making its assignment to your computer impossible. The information generated by the cookie on your use of this website is not forwarded to any third party.

Generally, it is possible to avoid the use of cookies by adjusting your browser software accordingly. You might, however, not be able to use all the functions on our website to their full extent.

If you place an order with us, we will collect and store the data required for executing the subject of the contract, such as your name, address, telephone number, Email address etc. (so-called inventory data). In addition to this, we will provide you with a customer number and a password. This data enables you to view price lists and information on our products in our log-in area under

If you log in to our website with your customer number and the password, we will obtain the information listed under paragraph 2 via the protocol file. You hereby declare your explicit consent with our combining your inventory data with the previously collected anonymous usage data to form a user profile and the analysis of these for statistical purposes when you make use of the log-in area. The usage data is deleted regularly, every four weeks at the latest.
