The protection of your personal data during the processing of personal data on the occasion of your visit to our homepage is an important concern for us. Your data will be protected within the framework of the statutory provisions. We would like to inform you below about the nature and extent of the processing of personal data via this website in accordance with Article 13 of the General Data Protection Regulation (DSGVO).

II. information on the data protection officer

If you have any questions regarding data protection, please contact our external company data protection officer: Dr. Hans Daldrop of GINDAT GmbH Wetterauer Str. 6, 42897 Remscheid Mail: Tel. +49 (0) 2191 / 909 430

III. data processing via the website

Your visit to our website is logged. The following data, which your browser transmits to us, are initially recorded:

  • the IP address currently used by your PC or router
  • Date and time
  • Browser type and version
  • the operating system of your PC
  • the pages you viewed
  • Name and size of the requested file(s)
  • and, if applicable, the URL of the referring website.

This data is collected solely for the purposes of data security, to improve our website and for error analysis on the basis of article 6 paragraph 1 f DSGVO. We reserve the right to use this data in the event of system misuse in order to determine the reasons and the trigger for the misuse and to take legal action if necessary. Otherwise, the IP address of your computer will only be evaluated anonymously (shortened by the last 3 digits).

You can visit our website without providing any personal information.

We would like to point out that data transmission on the Internet (e.g. communication by e-mail) can have security gaps. A complete protection of data against access by third parties is not possible. You should therefore send confidential data to us by other means, e.g. by post.


The controller processes the personal data of applicants for the purpose of processing the application procedure. The legal basis is § 26 para. 1 S.1 BDSG. The processing can also take place electronically. This is particularly the case if an applicant submits relevant application documents to the data controller by electronic means, for example by e-mail or via a web form on the website. If the data controller concludes an employment contract with an applicant, the transmitted data is stored for the purpose of processing the employment relationship in compliance with the statutory provisions. If the controller does not conclude an employment contract with the applicant, the application documents are deleted after the advertised position has been filled, taking into account the statutory provisions, provided that no other legitimate interests of the controller conflict with deletion. Other legitimate interests in this sense include, for example, a duty of proof in proceedings under the General Equal Treatment Act (AGG). For this purpose, the data will be stored for 6 months after completion of the application procedure and then deleted.

Applications can only be processed by us if they are sent to the e-mail address "" or submitted via our application portal. If you use a different e-mail address from our company, your application will unfortunately not be recognised by our systems and therefore not be considered. Please remember that an e-mail is not a secure medium. Should your application reach our e-mail server at the above-mentioned e-mail address, we will protect your application with high technical and organisational measures. On the way of your application to our company, through the public internet, we have no influence and cannot guarantee the level of protection of your application. If your sending e-mail server supports STARTTLS, our e-mail server will also use STARTTLS and thus guarantee transport encryption.

VI. Google Web Fonts

This site uses so-called web fonts, which are provided by Google, for the uniform display of fonts. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland, Tel: +353 1 543 1000, Fax: +353 1 686 5660, E-Mail: .

The data processing in connection with cookies, which are used solely to create the functionality of our online offer, is based on our legitimate interest according to Art. 6 I f) DSGVO.

If you do not wish cookies to be used, you can set your browser to not accept cookies. Please note, however, that in this case you may not be able to use all functions of our website.

Facebook Business Tools

We use the Facebook Pixel, a Facebook business tool from Facebook Ireland Limited (Ireland, EU), on our website. For information on the contact details of Facebook Ireland and the contact details of the Facebook Ireland data protection officer, please refer to the Facebook Ireland data policy at

The Facebook pixel is a snippet of JavaScript code that allows us to track visitors' activity on our website. This tracking is called conversion tracking. The Facebook pixel collects and processes the following information (so-called event data) for this purpose:

  • Information about actions and activities of visitors to our website, such as searching for and viewing a product or purchasing a product;
  • Specific pixel information such as the pixel ID and the Facebook cookie;
  • Information about buttons clicked by visitors to the site;
  • Information present in the HTTP header, such as IP addresses, web browser information, page location, and referrer;
  • Information about the status of disabling/restricting ad tracking.

Some of this event data is information that is stored in the device you are using. In addition, cookies are also used via the Facebook pixel, via which information is stored on your end device used. Such storage of information by the Facebook pixel or access to information that is already stored in your end device only takes place with your consent.

Tracked conversions appear in the dashboard of our Facebook Ads Manager and Facebook Analytics. We may use the tracked conversions there to measure the effectiveness of our ads, to set Custom Audiences for ad targeting, for Dynamic Ads campaigns, and to analyze the effectiveness of our website's conversion funnels. The features we use through the Facebook Pixel are described in more detail below.

Processing of Event Data for AdvertisingPurposes
Event data collected through the Facebook Pixel is used for targeting our ads and improving ad delivery, personalising features and content, and improving and securing Facebook products.

For this purpose, event data is collected on our website by means of the Facebook Pixel and transmitted to Facebook Ireland. This only takes place if you have previously given your consent to this. The legal basis for the collection and transmission of personal data by us to Facebook Ireland is therefore Art. 6 (1) a DSGVO.

This collection and transfer of event data is carried out by us and Facebook Ireland as joint controllers. We have entered into a joint controller agreement with Facebook Ireland which sets out the allocation of data protection obligations between us and Facebook Ireland. In this agreement, we and Facebook Ireland have agreed, among other things,

  • that we are responsible for providing you with all the information pursuant to Art. 13, 14 DSGVO on the joint processing of personal data;
  • that Facebook Ireland is responsible for enabling the rights of data subjects under Articles 15 to 20 of the GDPR in respect of personal data held by Facebook Ireland following joint processing.

You can access the agreement concluded between us and Facebook Ireland at

Facebook Ireland is the sole controller of the subsequent processing of the submitted event data. For more information on how Facebook Ireland processes personal data, including the legal basis on which Facebook Ireland relies and how you can exercise your rights against Facebook Ireland, please see Facebook Ireland's Data Policy at

Processing of Event Data for Analytics
We have also engaged Facebook Ireland to report on the impact of our advertising campaigns and other online content based on the Event Data collected through the Facebook Pixel (Campaign Reports) and to provide analytics and insights about users and their use of our website, products and services (Analytics). We transfer personal data contained in the Event Data to Facebook Ireland for this purpose. The personal data submitted will be processed by Facebook Ireland as our processor to provide us with the campaign reports and analytics.

Personal data is only processed for the creation of analyses and campaign reports if you have previously given your consent to this. The legal basis for this processing of personal data is therefore Art. 6 (1) a DSGVO.

A transfer of data to Facebook Inc. in the USA cannot be excluded. The legal basis for this transfer is the standard contractual clauses for the transfer of personal data to processors in third countries. Please note the information in the section "Data transfer to third countries".

Google Marketing Services
We use the Google Ads Conversions marketing service provided by Google Ireland Limited (Ireland/EU). Google Ads allows us to place ads relevant to users on the Google advertising network (e.g. in search results, or on other websites), improve campaign performance reports and avoid serving ads to a user more than once. Each Ads client sets a different conversion cookie. These cookies cannot therefore be tracked across the websites of different Ads clients. A cookie ID is used to record which ads are played in which browser. In this way, multiple display of the same campaign can be prevented. Furthermore, cookie IDs can be used to record so-called conversions, i.e. whether a user sees an ad and later visits the advertiser's website and purchases something there.

We use the DoubleClick Floodlight marketing service provided by Google Ireland Limited (Ireland/EU). The service enables us to track and analyse the actions of users who visit our website after they have seen or clicked on one of our advertisements. For this purpose, so-called "floodlight tags" or tracking pixels and cookies are placed on our website. By means of this function, we can determine the efficiency of our online campaigns on our website.

Remarketing allows us to target users who have already interacted with our website. In doing so, our ads are delivered when this target group visits a Google website or a website in the Google advertising network. For these purposes, a code is executed by Google when our website is called up and so-called (re)marketing tags are integrated into the website. With their help, an individual cookie is stored on the user's device. The cookies can be set by various domains, including,, or This file records which websites users have visited, what content they are interested in and which offers have been used. In addition, technical information about the browser and operating system, referring websites, time of visit and other information about the use of the online offer are stored. All user data is only processed as pseudonymous data and does not contain any information with which we can personally identify users. The advertisements displayed are therefore not specifically displayed for a person, but for the owner of the cookie.

Google Marketing Services will only be used with your consent pursuant to Art. 6 (1) a DSGVO.

In the case of Google services, the transmission of data to Google Inc. in the USA cannot be ruled out. Please note the information in the section "Data transfer to third countries". Further information on data protection at Google can be found in Google's data protection information at"

Data transfer to third countries
Visiting our website may involve the transfer of certain personal data to third countries, i.e. countries in which the GDPR is not applicable law. Such a transfer takes place in a permissible manner if the European Commission has determined that an adequate level of data protection is required in such a third country. If such an adequacy decision by the European Commission does not exist, a transfer of personal data to a third country shall only take place if appropriate safeguards pursuant to Article 46 of the GDPR are in place or if one of the conditions of Article 49 of the GDPR is met.

Unless otherwise stated below, we use the EU standard contractual clauses for the transfer of personal data to processors in third countries as appropriate safeguards:

Finally, the duration of storage can also depend on the statutory limitation periods, which, for example, according to §§ 195 ff. of the German Civil Code (BGB), can generally be three years, but in certain cases up to thirty years.

XI. Right of appeal to a supervisory authority

Under Art. 77 DSGVO, every data subject has a right of appeal to a supervisory authority if he or she believes that the processing of personal data relating to him or her violates the DSGVO.

Liability for contents

As a service provider we are responsible for our own contents on these pages according to the general laws (according to § 7 Abs.1 TMG). As a service provider, however, we are not obliged to monitor transmitted or stored third-party information or to investigate circumstances that indicate illegal activity (§8 to §10 TMG). This does not affect our obligations to remove or block the use of information in accordance with general laws.

If we become aware of any such legal infringements, we will remove the content in question immediately.

Liability for links
