  • Meta/communication data (e.g. device information, IP addresses)
  • Contact details (e.g. e-mail, address, telephone numbers)
  • Proof of consent

Categories of data subjects

Visitors and users of the online offer. In the following, we refer to the persons concerned collectively as "users".

Purpose of processing

We process personal data for the following purposes

  • Operation of this website
  • Responding to contact requests and communication with users

We do not process personal data for profiling purposes.

Processing of personal data (in detail)

In the following we inform you, in accordance with article 13 of the DPA, about the type of data processed, the categories of data subjects, the processing operations carried out, their purposes and the relevant legal bases.


The hosting services used by us serve to provide the operation of this online offer. These include infrastructure and platform services, computing capacity, storage space and database services, e-mail transmission, ensuring processing security and technical maintenance services.

In doing so, we, or our hosting provider, process the above-mentioned types of personal data of the users of this online offer. We have concluded a contract with the hosting provider for order processing in accordance with Art. 28 DS-GVO.

We operate our websites exclusively on servers in Germany.

The legal basis is our legitimate interest in the efficient and secure provision of this online service in accordance with Art. 6 Para. 1 letter f) DS-GVO.

Storage of access data

We log every access to our website and store information in log files that your browser sends to us. This includes IP address, operating system used, web browser used, previously visited web pages (if transmitted by the web browser), the web pages you visit on our website, date and time of access and the amount of data transmitted in each case. We collect this data exclusively for statistical purposes; it is not combined with other data sources.

We store this data anonymously for 60 days. The same applies to mail logs resulting from the sending of e-mails from the web environment (e.g. via forms). We delete error logs after 7 days.

The legal basis is our legitimate interest in improving the service of our website in accordance with Art. 6 Para. 1 lit. f) DS-GVO.


Our website uses cookies. These are small text files that your web browser stores on your end device and which help to make our offer more user-friendly, effective and secure.

Some cookies are "session cookies." Such cookies are automatically deleted after the end of your browser session. On the other hand, other cookies (e.g. from Matomo) remain on your end device until you delete them yourself. Such cookies help us to recognise you when you return to our website.

With a modern web browser you can monitor, restrict or prevent the setting of cookies. Many web browsers can be configured so that cookies are deleted automatically when you close the program. Disabling cookies may result in limited functionality of our website.

The legal basis for the storage of cookies is our legitimate interest in accordance with Art. 6 Para. 1 letter f) DS-GVO. This is intended to make our website more user-friendly, effective and secure.

Online forms or requests by e-mail

If you provide us with further personal data via our website, this is always done on a voluntary basis. We expressly point this out on our web pages and do not permit a transfer from online forms (e.g. contact, application or order forms) until your consent has been actively confirmed in the form.

Based on your online confirmation as well as in the case of an unsolicited sending of your data by e-mail, we assume your conscious consent.

This data and other information you provide us with will be recorded and stored by us in accordance with the provisions of the German Telemedia Act and on the basis of the current data protection regulations.

Your data will be processed exclusively on the basis of your consent and only for the intended purpose, e.g. to answer your enquiry or process your application. A revocation of your already given consent is possible at any time. An informal notification by e-mail is sufficient for the revocation. The legality of the data processing procedures carried out up to the revocation remains unaffected by the revocation.

Your transmitted data will remain with us until you request us to delete it, revoke your consent to its storage or until there is no longer any need to store the data (e.g. after answering the enquiry, at the end of the application process or if you unsubscribe from a newsletter). This data will then be deleted or blocked immediately, provided that there are no legal provisions, in particular obligations to retain data.

The data will not be used for any other purpose or passed on to third parties without your express consent. We use the collected data for internal purposes only.

The legal basis for this is our legitimate interest according to Art. 6 Para. 1 S. 1 f) DS-GVO (e.g. to answer your enquiry by e-mail).

Newsletter data/Info-Mail

In order to send our newsletter, we require an e-mail address from you, as well as your conscious and verifiable consent to the storage and processing of this data and to receive the newsletter.

A verification of the e-mail address provided is necessary and the receipt of the newsletter must be agreed to. Additional data is not collected or is voluntary. The data will be used exclusively for sending the newsletter.

For the dispatch of our newsletter, we use the software rapidmail, a product of rapidmail GmbH located at 79098 Freiburg, Augustinerplatz 2.

The data collected when registering for the newsletter will be processed exclusively on the basis of your consent. It is possible to revoke your consent at any time. To revoke your consent, simply send us an informal message by e-mail or unsubscribe using the "Unsubscribe" link in the newsletter. Your data in connection with the dispatch of the newsletter will then be deleted immediately. The legality of data processing procedures already carried out remains unaffected by the revocation.

The processing takes place on servers in Germany. Further details on data protection at rapidmail can be found at

To fully comply with the legal data protection requirements, we have concluded a contract with rapidmail on the processing of orders in accordance with Art. 28 DS-GVO and transfer your data such as first name, surname, title and e-mail address.

The legal basis for the dispatch of the newsletter is your consent within the meaning of art. 6 para. 1 letter a) in conjunction with art. 7 DS-GVO (conditions for consent) and art. 7 para. 2 no. 3 UWG (requirement of express consent). The legal basis for the logging of the registration is our legitimate interest in the proof that the shipment was made with your consent.

Deletion of data

The data processed by us will be deleted or restricted in their processing in accordance with Articles 17 and 18 DS-GVO. Unless expressly stated in this data protection declaration, the data stored by us will be deleted as soon as they are no longer required for their intended purpose and the deletion does not conflict with any statutory storage obligations. If the data are not deleted because they are required for other and legally permissible purposes, their processing is restricted. This means that the data is blocked and not processed for other purposes. This applies, for example, to data that we are required to retain for commercial or tax law reasons.

Your rights as data subject

You have various rights regarding your personal data. If you wish to assert these rights, please send your request informally by e-mail or post, stating your first name and surname and your contact details, to the above-mentioned person responsible or our data protection officer.

Right to confirmation and information

In accordance with Art. 15 DS-GVO, you have the right at any time to receive confirmation from us as to whether we are processing personal data relating to you. If this is the case, you have the right to request information from us free of charge about the personal data stored about you, together with a copy of this data.

Right of rectification

Right of withdrawal

You have the right to revoke your consent at any time with effect for the future in accordance with Art. 7 Ab3 DS-GVO. The legality of the data processing carried out up to the time of revocation remains unaffected by the revocation.

Right of objection

You have the right to object at any time to the future processing of data concerning you in accordance with Art. 21 DS-GVO. The objection may in particular be made against processing for the purposes of direct advertising.

An objection is also possible in the case of lawful processing of your data pursuant to Art. 6 (1) (e) or (f), unless we can demonstrate compelling reasons for processing which are worthy of protection and which outweigh your interests, rights and freedoms, or unless the processing serves to assert, exercise or defend legal claims.

Right of cancellation ("right to be forgotten")

If we have made the personal data public and we have been informed according to Art.

Right to limitation

According to Art. 18 DSGVO, you have the right to demand that we restrict processing. We will comply with this after examining certain conditions.

Right to data transferability

According to Art. 20 DSGVO, you have the right to receive your personal data that you have provided us with in a structured, common and machine-readable format, provided that the processing is based on consent or on a contract, that the processing is carried out using automated procedures and that this is technically feasible.

Right to non-exclusive automated decision making

According to Art. 22 DS-GVO, you have the right not to be subjected to a decision based solely on automated processing - including profiling - which has legal effect vis-à-vis you or significantly affects you in a similar way.

No automated decision-making based on the personal data collected will take place.

Right to appeal to the competent supervisory authority

As a data subject, you have a right of appeal to the competent supervisory authority in the event of a breach of data protection law under Article 77 D-GVO. The competent supervisory authority for data protection issues is the data protection commissioner of the federal state in which our company is located. The following link provides a list of the data protection officers and their contact details:

Protection of stored data

In accordance with Art. 32 of the DS-GVO and taking into account the state of the art, the implementation costs and the nature, scope, circumstances and purposes of the processing as well as the varying degrees of probability and seriousness of the risk to the rights and freedoms of natural persons, we take appropriate technical and organisational measures to ensure a level of protection appropriate to the risk.


Such measures shall include in particular safeguarding the confidentiality, integrity and availability of data by controlling physical access to data, as well as access, input, disclosure, safeguarding of availability and segregation of data relating to them. Furthermore, we have established procedures to ensure that data subjects' rights are exercised, data is deleted, and we respond to any threats to the data. Furthermore, we take the protection of personal data into account as early as the development or selection of hardware, software and processes, in accordance with the principle of data protection through the design of technology and through data protection-friendly default settings (Art. 25 DS-GVO).

However, it cannot be ruled out that unencrypted data can be viewed by third parties.

Furthermore, we do not guarantee that our service will be available at certain times; disturbances, interruptions or failures cannot be excluded. The servers used by us are regularly and carefully secured.

Protection of the transmission of data

For security reasons and to protect the transmission of confidential content that you send to us as the site operator, our website uses SSL or TLS encryption. This means that data that you transmit via this website cannot be read by third parties. You can recognise an encrypted connection by the "https://" address line of your browser and the lock symbol in the browser line.

We would like to point out that in general (e.g. when communicating by e-mail) no secure transmission can be guaranteed with regard to data transmission via the Internet. Sensitive data should therefore either not be transmitted at all or only via a secure connection (SSL).

Cooperation with contract processors and third parties

If, in the course of our processing, we disclose data to other persons and companies (processors or third parties), transfer it to them or otherwise grant them access to the data, this is only done on the basis of a legal authorisation (e.g. if the data must be transferred to third parties, such as payment service providers, in accordance with Art. 6 Para. 1 letter b) DS-GVO for the fulfilment of the contract), if you have given your consent, if a legal obligation provides for this or on the basis of our legitimate interests (e.g. when using agents, web hosts, etc.).

If we commission third parties to process data on the basis of a "contract for order processing", this is done on the basis of Art. 28 DS-GVO.

Transfer to third countries (outside the EU)

Data transfer to bodies or persons outside the EU does not take place and is not planned.

Social Media

The content on our websites can be shared in social networks. There are no plugins on our pages that are provided by these social networks. An automatic transfer of user data to the operators of these platforms does not take place on our pages. A contact with the social networks only takes place when the user actively clicks on a social button.

Our users can post the contents of our pages in social networks without having complete surfing profiles created by the operators of the networks.

We would like to point out that user data may be processed outside the European Union for market research and advertising purposes. This can result in risks for the users, because the enforcement of the users' rights could be made more difficult. With regard to US providers who are certified under the Privacy Shield, we would like to point out that they thereby undertake to comply with the data protection standards of the EU.

For a detailed presentation of the respective processing and the possibilities of objection (opt-out), we refer to the following linked information of the providers.

Also in the case of requests for information and the assertion of user rights, we would like to point out that these can most effectively be asserted with the providers. Only the providers have access to the data of the users and can directly take appropriate measures and provide information. Should you nevertheless require assistance, you can contact us.


We have implemented a "XING Share Button" on our website. When you visit the site, your web browser connects to the XING servers (XING AG XING AG, Dammtorstraße 29-32, 20354 Hamburg, Germany), through which the "XING Share Button" functions are provided (e.g. calculating the counter value). We would like to point out that we do not have any knowledge of the content of the data transmitted or of the use of such data by XING.

Further information about XING can be found here:
