Purpose and legal basis of processing

We process your personal data for the purpose of establishing an employment relationship in compliance with Art. 6 (1) p. 1 lit. b DSGVO in conjunction with Art. 88 DSGVO and Section 26 BDSG.

If applicable, we are obliged to process your personal data pursuant to Art. 6 (1) sentence 1 lit. c DSGVO. Various legal obligations may exist in this regard (e.g. obligations under the German Commercial Code; the German Fiscal Code; to store tax-relevant data; under the German Social Security Code; under the General Equal Treatment Act; or other relevant regulations).


Type of data categories processed

We process personal data that we receive from you as part of the application process, e.g. through letters of application, CVs, references, correspondence, telephone or verbal information. 

The following categories of data may be affected:

  • Personal data (surname, first name, date of birth)
  • Address data (address, place of residence)
  • Contact data (telephone no., e-mail address)
  • Application data (cover letter, references, resume)

First of all, our HR department and accounting department have access to your data, but also the specialist department of the position for which you have applied. Our administrators and order processors have technically necessary the possibility to access data processed by means of IT. They are strictly bound by our instructions and may not process the data for their own purposes. In certain cases, we may need to disclose your personal data to third parties, such as to our bank if you receive a reimbursement or to the postal service if we communicate with you by letter.

Furthermore, third parties may receive data for certain purposes if this is required by law as part of your application (e.g. notification to the Federal Employment Agency).

Data is not transferred to bodies in countries outside the European Union (so-called third countries).


Duration of data storage

Your personal data will be stored for as long as is necessary to fulfill our contractual and legal obligations in the application process. In the event of a successful application, your personal data will be placed in your personnel file and used to implement and terminate the employment relationship.

If we are currently unable to offer you employment, we will continue to process your data on the basis of our legitimate interests pursuant to Art. 6 (1) p. 1 lit. f DSGVO for up to 6 months after sending the rejection in order to be able to defend ourselves against any legal claims. In the case of your consent to store your data beyond the prescribed period, the duration may be correspondingly longer (max. two years).

  • Name, first name
  • Date of birth
  • E-mail address
  • Applicant number

and will be permanently deleted after 24 months.

If the data is no longer required for the fulfillment of contractual or legal obligations, it will be deleted, unless storage is required due to legal retention periods (e.g. to fulfill commercial and tax retention periods of ten years).

V. Newsletter

2. The legal basis for this is your consent in accordance with Art. 6 para. 1 p. 1 lit. a DSGVO. We use the data collected exclusively for sending the newsletter. 3.

Description and Purpose:

We use rapidmail for sending newsletters. The provider is rapidmail GmbH, Wentzingerstraße, 21, 79106 Freiburg, Germany. Among other things, rapidmail is used to organize and analyze the dispatch of newsletters. The data you enter for the purpose of receiving the newsletter is stored on rapidmail's servers in Germany. 

If you do not want any analysis by rapidmail, you must unsubscribe from the newsletter. For this purpose, we provide a corresponding link in every newsletter message. Furthermore, you can also unsubscribe from the newsletter directly on the website.

For the purpose of analysis, the e-mails sent with rapidmail contain a so-called tracking pixel, which connects to the servers of rapidmail when the e-mail is opened. In this way, it can be determined whether a newsletter message has been opened. Furthermore, with the help of rapidmail, we can determine whether and which links in the newsletter message are clicked. All links in the e-mail are so-called tracking links, with which your clicks can be counted.

Legal basis: The legal basis for data processing is Art. 6 para. 1 p. 1 lit. a DSGVO.

Recipient: The recipient of the data is rapidmail GmbH.

Transmission to third countries: A transfer of data to third countries does not take place.

Duration: The data stored by us within the scope of your consent for the purpose of the newsletter will be stored by us until you unsubscribe from the newsletter and will be deleted from our servers as well as from the servers of rapidmail after you unsubscribe from the newsletter. Data stored by us for other purposes (e.g. e-mail addresses for the member area) remain unaffected by this.

Possibility of revocation: You have the possibility to revoke your consent to data processing with effect for the future at any time. The legality of the data processing operations already carried out remains unaffected by the revocation.

Further data protection information: For more details, please refer to the data security information of rapidmail at: For more information on the analysis functions of rapidmail, please refer to the following link:

VII. Other tools

Google Tag Manager

1. Through the Google Tag Manager, so-called tags (i.e. relevant information for others such as code snippets or also pixels for other tools) are installed on the website. The tag manager works by installing a container with a unique container ID on the website. All relevant information for the tools used is then stored in this container.

2. The further implementation of tools then takes place via the user interface of the Tag Manager. The Tag Manager thus creates a central place through which all tools can be started and also switched off again. The Google Tag Manager takes care of triggering other tools by collecting the relevant information for the built-in tools. However, a processing of the collected data does not take place through the Tag Manager, it is only forwarded to the respective tool. If a deactivation has been made at domain or cookie level, this remains in place for all tracking tags implemented with Google Tag Manager.

3. The legal basis for the use of the tag manager is our legitimate interest according to Art. 6 para. 1 p. 1 lit. f DSGVO in a functioning management of the other tools of this website.

Without this "Enhanced Data Protection", a connection to the YouTube server in the USA is established as soon as you call up one of our Internet pages on which a YouTube video is embedded.

2. As soon as you visit one of our pages that has a YouTube video embedded, YouTube sets at least one cookie that stores your IP address and our URL. If you are logged into your YouTube account, YouTube can usually assign your interactions on our website to your profile using cookies. This includes data such as session duration, bounce rate, approximate location, technical information such as browser type, screen resolution or your internet provider. Other data may include contact details, any ratings, sharing of content via social media or adding to your favorites on YouTube. If you want to prevent this, you must either log out of YouTube before visiting our website or make the appropriate settings in your YouTube user account.

3. If you are not signed in to a Google Account or YouTube account, Google stores data with a unique identifier associated with your device, browser, or app. For example, your preferred language setting is retained. But a lot of interaction data can't be stored because fewer cookies are set.

4. The legal basis is Art. 6 para. 1 lit. f DSGVO. Our legitimate interest lies in the quality improvement of our website.

5. For the purpose of functionality as well as for the analysis of user behavior, YouTube permanently stores cookies on your end device via your internet browser. If you do not agree with this processing, you have the option to prevent the storage of cookies by a setting in your Internet browser.

6. The legal basis for setting the cookie is your consent pursuant to Art. 6 (1) p. 1 lit. a DSGVO. Details on this can be found above under the item "Cookies".

7. For more information on the purpose and scope of data collection and processing by YouTube, please see the privacy policy. There you will also find further information on your rights and setting options to protect your privacy: Google also processes your personal data in the USA.

IX. Social Media

1. General information

We maintain publicly accessible profiles on social networks. The social networks used by us in detail can be found below. 

Social networks can generally analyze your user behavior comprehensively when you visit their website or a website with integrated social media content (e.g. like buttons or advertising banners). Visiting our social media profile triggers numerous processing operations relevant to data protection.

2. Personal data

If you are logged into your social media account and visit our social media profile, the operator of the social media portal can assign this visit to your user account. However, your personal data may also be collected under certain circumstances if you are not logged in or do not have an account with the respective social media portal. In this case, this data collection takes place, for example, via cookies that are stored on your end device or by recording your IP address.

With the help of the data collected in this way, the operators of the social media portals can create user profiles in which your preferences and interests are stored. In this way, you can be shown interest-based advertising inside and outside the respective social media profile. Provided you have an account with the respective social network, the interest-based advertising may be displayed on all devices on which you are or were logged in.

Please also note that we cannot track all processing on the social media portals. Depending on the provider, further processing operations may therefore be carried out by the operators of the social media portals. For details, please refer to the terms of use and data protection provisions of the respective social media portals.

3. Reference to risks

We would like to point out that the respective providers may process user data outside the European Union. This may result in risks for the users because, for example, it could make it more difficult to enforce the rights of the users. With regard to U.S. providers that offer guarantees of a secure level of data protection through, for example, EU standard contractual clauses, we point out that they thereby undertake to comply with the data protection standards of the EU.

4. Purpose of the processing/legal basis

Our own processing of personal data on our social media sites is based on our legitimate interests according to Art. 6 para. 1 p. 1 lit. f DSGVO, in order to inform about our offer there, to make posts more attractive, to find the right time for publication, as well as to communicate with customers, interested parties and users active there. We have no influence on any further processing by the providers.

For the setting of the aforementioned cookies, the legal basis is your consent granted in accordance with Art. 6 (1) p. 1 lit. a DSGVO. Details on this can be found above under the item "Cookies" or under "Social Media Plugins".

5. Joint responsibility

If you visit one of our social media sites (e.g. Facebook), we are jointly responsible with the operator of the social media platform for the data processing operations triggered during this visit. Please note that despite the joint responsibility with the social media portal operators, we do not have full influence on the data processing operations of the social media portals. Our options are largely determined by the corporate policy of the respective provider.

6. Rights management

In principle, you can assert your rights both against us and against the operator of the respective social media portal. However, we would like to point out that these can be asserted most effectively with the operators. Only the operators have access to the users' data and can take appropriate measures and provide information directly. If you still require assistance, please feel free to contact us.

7. Storage duration

The data collected directly by us via the social media profile is deleted from our systems as soon as the purpose for storing it no longer applies, you request us to delete it, revoke your consent to store it, or the purpose for storing the data no longer applies. Stored cookies remain on your terminal device until you delete them. Mandatory legal provisions - in particular retention periods - remain unaffected. We have no influence on the storage period of your data, which is stored by the operators of social networks for their own purposes. For details, please contact the operators of the social networks directly (e.g. in their privacy policy, see below).

8. Provider data protection

For a detailed presentation of the respective forms of processing and the options to object (opt-out), we refer to the data protection declarations and information provided by the providers of the respective social media networks, over which we have no influence and which apply when the respective websites are called up.

Linking social media profiles via graphic or text link

1. On our website, we also link to social media profiles on the platforms listed above. The integration takes place via a linked graphic or a text link of the respective platform. The use of this linking prevents a connection to the respective server of the platform from being automatically established when a website with a social media link is called up in order to display a graphic of the respective platform itself. The user is only forwarded to the service of the respective platform by clicking on the corresponding graphic.

2. After the user has been forwarded, information about the user is collected by the respective provider. It cannot be ruled out that the data collected in this way will be processed in the USA. Please note our information on data transfers to the USA.

3. This is initially data such as IP address, date, time and page visited. If the user is logged into his user account of the respective platform during this time, the operator may be able to assign the collected information of the specific visit of the user to his personal account. If the User interacts via a "Share" button of the respective platform, this information can be stored in the User's personal user account and may be published. If the user wants to prevent the collected information from being directly assigned to his user account, he must log out before clicking on the graphic. In addition, it is possible to configure the respective user account accordingly.


LinkedIn Insight Tag

Our website uses the conversion tool "LinkedIn Insight Tag" from LinkedIn Ireland Unlimited Company. This tool creates a cookie in your web browser, which enables the collection of the following data, among others: IP address, device and browser properties, and page events (e.g. page views).

This data is encrypted, anonymized within seven days, and the anonymized data is deleted within 90 days.

LinkedIn does not share personal data with DCG, but provides anonymized reports on website audience and ad performance. In addition, LinkedIn offers the possibility of retargeting via the Insight Tag. DCG can use this data to display targeted advertising outside of its website without identifying you as a website visitor. For more information on data protection at LinkedIn, please refer to the LinkedIn privacy notices.

LinkedIn members can control the use of their personal data for advertising purposes in their account settings. To deactivate the Insight tag on our website ("opt-out"), please go to the website of LinkedIn „“.

X. Special forms of use of the website

Userlike Live Chat

We use a chat software of the company "" Userlike UG (haftungsbeschränkt), Probsteigasse 44-46, 50670 Cologne, Germany. You can use the chat like a contact form to chat almost in real time with our employees. When starting the chat, the following personal data is collected:

  • Date and time of the call, 
  • browser type/version,
  • IP address,
  • operating system used,
  • URL of the previously visited website,
  • amount of data sent
  • and if specified: First name, last name, and e-mail address.

Depending on the course of the conversation with our employees, further personal data may arise in the chat, which is entered by you. The nature of this data depends largely on your request or the problem you describe to us. The purpose of processing all this data is to provide you with a fast and efficient way to contact us and thus improve our customer service.

All our employees have been and will be trained on the subject of data protection and taught how to handle customer data safely and confidentially. All our employees are bound to confidentiality and have accordingly signed an addendum in their employment contracts to the obligation to maintain confidentiality and to observe data protection.

By accessing the website, the chat widget is loaded in the form of a JavaScript file from AWS Cloudfront. The chat widget technically represents the source code that runs on your computer and enables chat.

Furthermore, DC-Datacenter-Group GmbH stores the chat history for a period of 1 year. This serves the purpose of possibly sparing you extensive explanations about the history of your request as well as for the constant quality control of our chat offer. The processing is therefore permitted in accordance with Art. 6 para. 1 p. 1 lit. f DSGVO. If you do not wish this, you are welcome to inform us of this using the contact details listed below. Stored chats will then be deleted by us immediately. The storage of chat data also serves the purpose of ensuring the security of our information technology systems. This is also our legitimate interest, which is why the processing is permitted under Art. 6 (1) p. 1 lit. f DSGVO. You can find more information in the data protection provisions at „“ of Userlike UG (haftungsbeschränkt).
