2) Collection and storage of personal data and the nature and purpose of its use 

a) When visiting the website

When you visit our website, information is automatically sent to the server on our website by using the browser used on your device. This information is temporarily stored in a so-called log file. The following information is collected without your intervention and stored until the automated deletion: 

  • Name of the file retrieved 
  • Date and time of retrieval 
  • Amount of data transferred 
  • Report whether the retrieval was successful 
  • Description of the type of web browser used 
  • Operating system used 
  • The previously visited site 
  • Provider 
  • Your IP address 

The above data is processed by us for the following purposes: 

  • Ensure a smooth connection of the website, 
  • Ensure convenient use of our website, 
  • Evaluation of system security and stability, as well as 
  • For further administrative purposes. 

The legal basis for data processing is Art.6 (1) lit.f GDPR. Our legitimate interest follows from the purposes listed above for data collection. Under no circumstances do we use the collected data for the purpose of drawing conclusions about you as a person. 

In addition, when you visit our website, we use cookies as well as analytical and marketing services. For more details, see the Sec. 5 – 7 of this Privacy Statement. 

b) When using our contact form

If you have any questions, we offer you the opportunity to contact us via a form provided on the website. It is necessary to provide your name, a valid e-mail address and the specific request so that we know who the request is from and in order to be able to respond to it. Further information can be provided voluntarily. 

The personal data collected for the use of the contact form by us will be deleted after the request you have made has been completed, unless another basis of legitimacy (e.g. a specific order) entitles further processing. 

Data processing for the purpose of contacting us is carried out in accordance with Art.6 paragraph 1 lit.b GDPR on the basis of your specific request. 

c) When using our newsletter

On our website you can subscribe to a free e-mail newsletter. When you sign up for the newsletter, the data from the input mask is transmitted to us. 

  • Name 
  • Company 
  • Title 
  • Email address 

In addition, the following data are collected at the time of registration: 

  • IP address of the calling computer 
  • Date and time of registration 

As part of the registration process, your consent will be obtained for the processing of the data and reference to this privacy policy will be referred to. 

If you hire us to provide services and store your e-mail address, it can subsequently be used by us to send a newsletter. In such a case, only direct mail for similar products or services will be sent via the newsletter. 

In connection with the data processing for the sending of newsletters, the data is not passed on to third parties. The data will only be used to send the newsletter. 

The purpose of collecting the user’s e-mail address is to deliver the e-mail newsletter. The collection of other personal data as part of the registration process is intended to prevent misuse of the services or the e-mail address used. 

The data will be deleted as soon as it is no longer necessary to achieve the purpose of its collection. The user’s e-mail address is therefore stored as long as the newsletter is subscribed to or unless unsubscribed. 

The other personal data collected as part of the registration process is usually deleted after a period of seven days. 

The subscription to the newsletter can be canceled by the affected user at any time. To this end, there is a corresponding link in each newsletter. This also allows for a revocation of the consent to the storage of the personal data collected during the registration process. 

The legal basis for the processing of the data after registration for the newsletter by the user is provided if the user has given its consent (Art.6 paragraph 1 lit.a GDPR). The legal basis for sending the newsletter as a result of the sale of goods or services is Article 6 (1) lit. f in conjunction with Section 7 (3) of the UWG. 

Use of the shipping service provider “MailChimp” 

The newsletter is sent via “MailChimp,” a newsletter delivery platform of the US provider Rocket Science Group, LLC, 675 Ponce De Leon Ave NE #5000, Atlanta, GA 30308, USA. 

The e-mail addresses of our newsletter recipients, as well as their other data described in the context of these notices, are stored on MailChimp’s servers in the USA. MailChimp uses this information to send and evaluate newsletters on our behalf. Furthermore, MailChimp says that MailChimp can use this data to optimize or improve its own services, for example to technically optimize the shiftwork and presentation of the newsletters or for economic purposes, in order to determine from which Countries the recipients come. However, MailChimp does not use the data of our newsletter recipients to write to them themselves or to pass it on to third parties. 

We rely on MailChimp’s reliability and IT and data security. MailChimp is certified under the US-EU Privacy Shield Agreement and is committed to complying with EU data protection requirements. We have also entered into a “data processing agreement” with MailChimp. This is a contract in which MailChimp undertakes to protect the data of our users, to process them on our behalf in accordance with its privacy policy and, in particular, not to pass it on to third parties. You can view MailChimp’s privacy policy here. 


To sign up for the newsletter, it is sufficient to provide your email address. 

As an option, we ask you to provide your first and last name. This information is only used to personalize the newsletter. We also ask you to provide your date of birth, gender and industry as an option. We use this information only to adapt the contents of the newsletter to the interests of our readers. 

Statistical survey and analysis 

The newsletters contain a so-called “web-beacon,” i.e. a pixel-sized file, which is retrieved from the MailChimp server when the newsletter is opened. As part of this retrieval, technical information, such as information about the browser and your system, as well as your IP address and time of retrieval, will be collected first.  This information is used for the technical improvement of the services on the basis of technical data or target groups and their reading behavior on the basis of their retrieval points (which can be determined with the help of the IP address) or access times. 

Statistical surveys also include determining whether newsletters will open, when they will open and which links will be clicked. For technical reasons, this information can be assigned to the individual newsletter recipients. However, it is neither our ambition nor that of MailChimp to observe individual users. The evaluations serve us much more to recognize the reading habits of our users and to adapt our content to them or to send different content according to the interests of our users. 

Online call and data management 

There are cases where we direct newsletter recipients to MailChimp’s websites. For example, our newsletters contain a link with which newsletter recipients can access the newsletters online (e.g. in case of presentation problems in the e-mail program). In addition, newsletter recipients can correct their data, such as the e-mail address afterwards. Similarly, MailChimp’s privacy policy is only available on its website. 

In this context, we pointed out that cookies are used on the MailChimp websites and that personal data is thus processed by MailChimp, its partners and service providers (e.g. Google Analytics). We have no control over this data collection. For more information, see MailChimp’s privacy policy. We also draw attention to the possibilities of objection to data collection for advertising purposes on the websites the European area). 


You can cancel the receipt of our newsletter at any time, i.e. Resist their consents. At the same time, your consents in its shipping via MailChimp and the statistical analyses will be extinguished.  A separate revocation of the dispatch via MailChimp or the statistical evaluation is unfortunately not possible. 

A link to the cancellation of the newsletter can be found at the end of each newsletter. 

Legal basis for the General Data Protection Regulation 

In accordance with the requirements of the General Data Protection Regulation (GDPR), which will apply from 25 May 2018, we inform you that the consent to the sending of e-mail addresses on the basis of Article 6 (1) lit. A, 7 GDPR and § 7 (2) (3), or paragraph 3 UWG. The use of the mail order service provider MailChimp, the conduct of statistical surveys and analyses as well as the logging of the registration procedure, are based on our legitimate interests in accordance with Article 6 (1) lit. f GDPR. Our interest is directed towards the use of a user-friendly and secure newsletter system that serves both our business interests and meets the expectations of users. 

We would also like to point out that you may object to the future processing of your personal data in accordance with the legal requirements in accordance with Article 21 GDPR at any time. The objection may be made in particular against processing for direct advertising purposes.

5.4) Google reCAPTCHA Privacy Policy

Our primary goal is to secure and protect our website for you and for us in the best possible way. To ensure this, we use Google reCAPTCHA from Google Inc. For the European region, the company Google Ireland Limited (Gordon House, Barrow Street Dublin 4, Ireland) is responsible for all Google services. With reCAPTCHA we can determine whether you are really a flesh and blood human being and not a robot or other spam software. By spam, we mean any unsolicited information sent to us by electronic means. With the classic CAPTCHAS, you usually had to solve text or image puzzles to check. With reCAPTCHA from Google we usually do not have to bother you with such puzzles. In most cases it is sufficient to simply check the box and confirm that you are not a bot. With the new Invisible reCAPTCHA version, you don’t even have to put a check mark. How this works exactly and especially which data is used for this purpose, you will learn in the course of this privacy policy.

What is reCAPTCHA?

reCAPTCHA is a free Captcha service from Google that protects websites from spam software and abuse by non-human visitors. This service is most commonly used when you fill out forms on the Internet. A captcha service is a kind of automatic turing test, which is supposed to ensure that an action on the internet is done by a human and not by a bot. In the classic Turing test (named after the computer scientist Alan Turing) a human being determines the difference between a bot and a human being. With Captchas this is also done by the computer or a software program. Classical Captchas work with small tasks that are easy to solve for humans, but have considerable difficulties for machines. With reCAPTCHA you don’t have to actively solve puzzles anymore. The tool uses modern risk techniques to distinguish humans from bots. Here you only have to tick the text field “I am not a robot” or with Invisible reCAPTCHA even this is no longer necessary. With reCAPTCHA, a JavaScript element is integrated into the source code and then the tool runs in the background and analyses your user behaviour. From these user actions, the software calculates a so-called captcha score. Google uses this score to calculate the probability that you are a human being even before you enter the captcha. reCAPTCHA or captchas in general are always used when bots could manipulate or abuse certain actions (such as registrations, surveys, etc.).

Why do we use reCAPTCHA on our website?

We only want to welcome people of flesh and blood on our site. Bots or spam-software of different kinds can stay at home. That’s why we do everything possible to protect ourselves and offer the best possible user-friendliness for you. For this reason we use Google reCAPTCHA from the company Google. So we can be pretty sure that we remain a “bot-free” website. Through the use of reCAPTCHA, data is transmitted to Google to determine whether you are really a human being. reCAPTCHA serves the security of our website and consequently your security. For example, without reCAPTCHA, it could happen that a bot registers as many e-mail addresses as possible during registration, in order to “spam” forums or blogs with unwanted advertising content. With reCAPTCHA we can avoid such bot attacks.

Which data is stored by reCAPTCHA?

reCAPTCHA collects personal data from users to determine whether the actions on our website really originate from people. This means that the IP address and other data that Google requires for the reCAPTCHA service can be sent to Google. IP addresses are almost always shortened within the member states of the EU or other signatory states to the Agreement on the European Economic Area before the data lands on a server in the USA. The IP address is not combined with any other data held by Google unless you are signed in with your Google Account while using reCAPTCHA. First, the reCAPTCHA algorithm checks whether Google cookies from other Google services (YouTube, Gmail, etc.) are already placed on your browser. Then reCAPTCHA sets an additional cookie in your browser and takes a snapshot of your browser window.

The following list of collected browser and user data is not complete. Rather, they are examples of data that, to our knowledge, are processed by Google.

Referrer URL (the address of the page the visitor comes from)

IP address (e.g.

Information about the operating system (the software that enables your computer to operate. Known operating systems are Windows, Mac OS X or Linux)

Cookies (small text files that store data in your browser)

Mouse and keyboard behavior (every action you perform with the mouse or keyboard is stored)

Date and language settings (which language or date you have preset on your PC is stored)

All Javascript objects (JavaScript is a programming language that allows websites to adapt to the user. JavaScript objects can collect all kinds of data under one name)

Screen resolution (shows how many pixels the image consists of)

It is indisputable that Google uses and analyzes this data even before you click on the checkbox “I am not a robot”. With the Invisible reCAPTCHA version even the ticking is omitted and the whole recognition process runs in the background. How much and what kind of data Google exactly stores is not known by Google in detail.

The following cookies are used by reCAPTCHA: Here we refer to the reCAPTCHA demo version of Google at All these cookies require a unique identifier for tracking purposes. Here is a list of cookies that Google reCAPTCHA has set on the demo version

Name: DV

Value: gEAABBCjJMXcI0dSAAAANbqc311188555-4

Purpose: As soon as you have checked the “I am not a robot” checkbox, this cookie will be set. The cookie is used by Google Analytics for personalized advertising. DV collects information in anonymous form and is also used to make user distinctions.

Expiration date: after 10 minutes

Note: This list cannot claim to be exhaustive, as experience has shown that Google always changes the choice of its cookies.

How long and where is the data stored?

By inserting reCAPTCHA, data is transferred from you to the Google server. Where exactly this data is stored is not clearly shown by Google, even after repeated requests. Without having received confirmation from Google, it can be assumed that data such as mouse interaction, time spent on the website or language settings are stored on Google’s European or American servers. The IP address that your browser transmits to Google is generally not merged with other Google data from other Google services. However, if you are logged into your Google account while using the reCAPTCHA plug-in, the data will be merged. Google’s different privacy policies apply.

How can I delete my data or prevent data storage?

If you do not want any data about you or your behaviour to be transmitted to Google, you must log out of Google completely and delete all Google cookies before you visit our website or use the reCAPTCHA software. In principle, the data is automatically transmitted to Google as soon as you visit our website. To delete this data again, you must contact Google support at

So when you use our website, you agree that Google LLC and its representatives automatically collect, process and use data.

You can learn more about reCAPTCHA on Google’s web development page at Google will go into more detail about the technical development of reCAPTCHA here, but you will search in vain for precise information about data storage and data protection issues. A good overview of the basic use of data at Google can be found in the company’s own privacy policy at 

6) Applicant data 

6.1 Required applicant data: 

When applying, we process data from you that we need as part of the application. This can be contact details, all applicant-related data (CV, certificates, qualifications, answers to questions, etc.) as well as, if applicable, bank details (to reimburse travel expenses). The legal basis for this is based on Section 26 of the Federal Data Protection Act.
