Personal data
Personal data are individual details about personal or objective relationships of a specific or identifiable natural person. This includes information such as your real name, your address, your telephone number, your position and your company. Information that is not directly associated with your real identity – such as the number of users of a site – is not personal data.

Collection and processing of personal data
We collect, save and process information in order to improve our services. When you visit our pages, our web servers automatically save, among other things, the date and time of access, the URL of the referring website, the file retrieved, the amount of data sent, the browser type and version, the operating system and your IP address.

Use and disclosure of personal data
You may be asked to provide personal information. Answering these questions is voluntary. We use personal data provided by you exclusively for purpose of your individual support, i.e. as a rule to answer your inquiry. We assure you that your data will be treated confidentially in accordance with the applicable data protection regulations.

Some of the Internet pages use so-called cookies. Cookies do not damage your computer and do not contain viruses. Cookies allow us to make our offer more user-friendly, more effective and safer. Cookies are small text files that are saved on your computer by your browser. Most of the cookies we use are so-called „session cookies“. They will be automatically deleted at the end of your visit. Other cookies remain saved on your system until you delete them. These cookies enable us to recognize your browser during your next visit. You can set your browser so that you are informed about the setting of cookies and only allow cookies in individual cases, accept cookies for certain cases or generally exclude them and activate the automatic deletion of cookies when closing the browser. If cookies are deactivated, the functionality of this website may be limited.

Purpose of processing

Provision and use of the website

Type and scope of data processing
When you visit our website, we collect the personal data that your browser automatically transmits to our server. This information is temporarily saved in a so-called log file. When you use our website, we collect the following data, which is technically necessary for us to display our website to you and to ensure its stability and security::

  • IP address of the requesting computer
  • Date and time of acces
  • Name and URL of the retrieved file
  • Website from which access is made (referrer URL)
  • Browser used and, if applicable, the operating system of your computer
  • Name of your access provider

Legal basis
Art. 6 para. 1 lit. f) DSGVO constitutes the legal basis for the mentioned data processing. The data processing is necessary for provision of a website and thus ensures protection of a legitimate interest of our company.

Duration of storage
The duration of storage of these log files is determined by our hosting provider and cannot be influenced by us. As a rule, this is a maximum of 60 days. The collection of data for provision of the website and the storage of data in log files is mandatory for the operation of the website. Consequently, there is no possibility for the user to object. A further storage can take place in individual cases, if this is legally prescribed.

Contact by e-mail

Type and scope of data processing
Every website visitor can send his request to the e-mail address given on our website. Our data collection is limited to the e-mail address of the e-mail account used by you to contact us and to the personal data you have sent by contacting us.

Legal basis
The compliance of data collection is based on Art. 6 para. 1 lit. f) DSGVO, since there is a parallel interest in establishing contact and communication between you and our company as well as a legitimate company interest in the processing of the above-mentioned data in order to be able to process your request.

Duration of storage
The duration of storage of the data above depends on the background of your contact. Your data will be deleted regularly if the intended purpose of the communication no longer applies and storage is no longer necessary (e.g. after final processing of your request).

In accordance with Art. 18 DSGVO, you can request the restriction of processing your personal data as long as as the accuracy of the data is disputed by you, the processing is unlawful, we no longer need the data and you refuse its deletion because you need it to assert, exercise or defend legal claims. You are also entitled to the right under Art. 18 DSGVO if you have objected against the processing in accordance with Art. 21 DSGVO.
