2. Collection and storage of personal data as well as method and purpose of their use

a) Data processing when visiting the KAEFER website

When you visit the KAEFER website, the browser on your device automatically sends information to the server on our website. This information is temporarily stored in a so-called log file. The following information is recorded without your intervention and stored for a short time only:

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

The aforesaid data will be processed by KAEFER for the following purposes:

  • Ensuring a smooth connection of the KAEFER website,
  • Ensuring the KAEFER website is user-friendly,
  • Evaluation of system security and stability, as well as
  • For other administrative and statistical purposes.

The legal basis for data processing is Article 6 para. 1 sentence 1 lit. f DSGVO. KAEFER’s legitimate interest follows from the purposes listed above for data collection. Under no circumstances does KAEFER use the data collected for the purpose of drawing conclusions about you personally.

In addition, KAEFER uses cookies and analysis services. You will find more detailed explanations under Sections 4 and 5 of this data protection declaration.

b) Data processing when using contact forms

On the KAEFER web­site there are various contact forms that you can use to get in touch with us. For example, a con­tact form for en­quir­ies of any kind, as well as a con­tact form for on­line ap­plic­a­tions as an external business partner for KAEFER (e.g. as subcontractor, supplier).

In the respective con­tact forms there are the fol­low­ing man­dat­ory fields which must be filled in e.g.: name, e-mail ad­dress and other personal business-relevant information. In the con­tact forms for the on­line ap­plic­a­tion as an external service provider, you can ap­ply dir­ectly to the rel­ev­ant op­er­a­tional KAEFER com­pany. A valid e-mail ad­dress is re­quired so that we know who sent the re­quest and to en­able us to re­spond to it. Ad­di­tional in­form­a­tion may be vol­un­tar­ily entered by you as a vis­itor/​in­quirer in the con­tact forms.

Data pro­cessing for the pur­pose of mak­ing con­tact, as de­scribed above, is car­ried out in ac­cord­ance with Art­icle 6 para. 1 sen­tence 1 lit. a DSGVO and with your vol­un­tary con­sent. This is pro­ceeded by the tech­nical op­tion of giv­ing con­sent by cross­ing a so-called check­box (opt-in). By cross­ing the box you as a vis­itor give your con­sent to KAEFER by send­ing the con­tact form to­gether with your data.

The per­sonal data col­lec­ted by KAEFER for the use of the con­tact forms will be auto­mat­ic­ally de­leted from the web­site after your re­quest has been pro­cessed.  

Your enquiry / application as an external business partner are forwarded internally within the KAEFER Group for processing. This will be done on the basis of your aforementioned consent. Your enquiry/application as a subcontractor will be processed and stored in the normal course of business and deleted as required by law.

c) Investor Portal at

The transmitted personal data will be used for the registration process in the Investor Portal ("Investor Log-In") and in connection with the provision of the Investor Portal with the information and data provided there. You hereby consent to the processing and storage of your personal data for the stated purposes. You are completely free to decide whether you give us your consent to process your personal data. The consent may be revoked in whole or in part at any time with effect for the future. The data requested in the registration process and the required declarations of consent are required for registration.

Registration only takes place if you have expressly agreed in advance. To this end, you will receive an e-mail containing an activation link. Activation can only take place if you click on the corresponding activation link. You can then log in with your registered e-mail address and password. This will give you access to the Investor Portal. There registered individuals are provided with relevant information such as annual and quarterly reports.

Data processing for the above-mentioned purposes is carried out in accordance with Art. 6 para. 1 sentence 1 lit. a DSGVO on the basis of your voluntary consent. This is preceded by the technical option of giving consent as a so-called checkbox (opt-in). By checking the box, you consent to KAEFER processing your data in the registration process and its further storage for the purpose of providing the Investor Portal. The personal data collected for the registration and further storage of KAEFER will only be stored for the period of your existing registration. They may be registered until 10 January 2024 at the latest (maturity of the KAEFER bonds). KAEFER will therefore delete your data by 11.01.2024 at the latest. If you revoke your consent to data processing and thus the registration in advance, we will delete your data immediately after receipt of the revocation taking into account the normal course of business. If you are notified that the data you provided during registration is not plausible for KAEFER, your data will also be deleted immediately.

d) Information reporting system KAEFER Compliance Helpline

The KAEFER website provides information on ways of reporting compliance violations. For this purpose, the electronic whistleblower system can be used. By using this whistleblower system, the user leaves the KAEFER website. Accordingly, the provider of this website is responsible for data protection and not KAEFER. Information concerning data protection can be found at

The KAEFER website also points out that these reports may also be sent to Corporate Compliance & Audit, Marktstraße 2, 28195 Bremen, Germany. Insofar as the reports contain personal data, data processing shall be carried out for the purpose of securing or monitoring pursuant to statutory provisions, regulatory standards and ethical principles on the basis of Art. 6 (1) sentence 1 lit. a DSGVO (your voluntary consent) or Article 6 (1) sentence 1 lit. f DSGVO (legitimate interests of KAEFER). The existence of such reports is based on KAEFER's legitimate interest in detecting and preventing damage to KAEFER, its employees and customers.

If you send a report to Corporate Compliance & Audit (KAEFER Isoliertechnik GmbH & Co. KG), we will take this as your consent to the receipt and processing of your personal data.

Incoming reports will be handled by a small circle of expressly authorised and specially trained employees of the KAEFER Compliance Organisation and will always be dealt with in strict confidence. The employees of the KAEFER Compliance Organisation examine the facts of the case and, if necessary, carry out further, case-related clarifications. When processing a report or in the context of a special investigation, it may be necessary to pass on information to other KAEFER employees or employees of other KAEFER Group companies, e.g. if the information relates to events involving subsidiaries. The latter may also be based in countries outside the European Union or the European Economic Area in which different regulations may exist for the protection of personal data. We always ensure that the relevant data protection regulations are complied with when passing on information.


3. Forwarding of personal data to third parties

Your personal data will not be forwarded to third parties for purposes other than those listed below.

Your personal data will only be passed on to third parties, if:

  • you have given your express consent pursuant to Article 6 para. 1 sentence 1 lit. a DSGVO,
  • the disclosure is necessary pursuant to Article 6 para. 1 sentence 1 f DSGVO in order to assert, exercise or defend legal claims and there is no reason to assume that you have an overriding interest worthy of protection in not disclosing your data (legitimate interest),
  • there is a legal obligation for the disclosure pursuant to Article 6 para. 1 sentence 1 lit. c DSGVO, as well as this being legally permissible and required under Article 6 para. 1 sentence 1 lit. b DSGVO for the processing of contractual relationships with you.

Google Analytics

KAEFER has a legitimate interest in such use within the meaning of Article 6 para. 1 sentence 1, lit. f DSGVO. Google Analytics is a web analysis service of Google Inc. ( (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA; hereinafter "Google"). In this context, on the one hand anonymised user profiles are created and on the other hand cookies (see Section 4) are used.

  • browser type/version,
  • operating system used,
  • referrer URL (the previously visited page),
  • host name of the accessing computer (IP address),

The information may also be transferred to third parties if this is required by law or if third parties process this data on behalf of the company. Under no circumstances will your IP address be merged with other data from Google. The IP addresses are anonymised so that an assignment is not possible (IP masking).

6. Data processing with plug.ins and links

KAEFER uses plug-ins and links on the KAEFER website on the basis of Article 6 para. 1 sentence 1 f DSGVO in order to make the KAEFER Group better known. The underlying advertising purpose is regarded as a legitimate interest within the meaning of the DSGVO. The responsibility for data protection-compliant operation is to be guaranteed by the provider in question. These plug-ins and links are integrated by KAEFER by means of the so-called two-click method in order to protect visitors to KAEFER’s website in the best way possible.

a) YouTube

The KAEFER website contains at least one plugin from YouTube, which belongs to Google Inc, based in San Bruno/California, USA. As soon as you visit the pages of the KAEFER website equipped with a YouTube plugin, no connection to the YouTube servers is established. In this respect KAEFER has activated YouTube's extended data protection mode. Only by confirming that you want to watch the YouTube video using the two-click method will the YouTube server be informed which special page of the KAEFER website you have visited. If you are also logged into your YouTube account, you would allow YouTube to associate your surfing behavior directly with your personal YouTube profile. You can prevent this option of allocation by logging out of your account beforehand. For more information on YouTube's collection and use of your data, please refer to YouTube's privacy policy at

b) LinkedIn

KAEFER uses a button to connect the social network LinkedIn in several places. This is only a link and not a so-called "social plugin". If you do not use the button, no information is transmitted to LinkedIn and no LinkedIn cookie is placed on your computer.

As soon as you click the button, without being logged in to LinkedIn, the login screen of LinkedIn opens in a new window after confirmation via the two-click method. In that case, it is possible that LinkedIn places a cookie on your hard drive. KAEFER acquires no knowledge of the content of the data transmitted and how LinkedIn uses it.

Sites contained within LinkedIn are operated exclusively by LinkedIn Corporation, 2029 Stierlin Court, Mountain View, CA 94304, USA (LinkedIn). The data LinkedIn collects on these pages is therefore outside KAEFER's sphere of knowledge and influence.

Further details on data collection and to your legal rights as well as setting options can be obtained from LinkedIn. These are available at

c) Use of Google Maps when searching for KAEFER sites:

The KAEFER website makes use of the Google Maps map service via an API. The provider is Google Inc, 1600 Amphitheatre Parkway Mountain View, CA 94043, USA. KAEFER has therefore integrated the above-mentioned map service into its website in order to make your journey to one of our locations as convenient as possible and to allow you to calculate your route and distance. This forms part of our customer service. This represents a legitimate interest pursuant to Article 6 I sentence f DSGVO.

To use the functions of Google Maps, you will however need to save your IP address. Google places a so-called NID cookie on your computer; This information is usually transferred to a Google server in the USA and stored there. The provider of this site has no influence on this data transmission. You can find more information about Google's handling of user data in Google's privacy policy:

Before the KAEFER website can load data from Google Maps, you must first agree to use the Google Maps services as part of the two-click method on the KAEFER website. You also have the option of generally switching off the map service and preventing data transmission to Google. To disable this, deactivate Java Script in your browser. In this case, the location finder can no longer be used by you. How to disable Java script can be found here: .

9. Data security

During your visit to the KAEFER website, KAEFER uses the SSL (Secure Socket Layer) method in conjunction with the highest level of encryption supported by your browser. Usually this is a 256-bit encryption. If your browser does not support a 256-bit encryption, KAEFER uses a 128-bit v3 technology instead. Whether a single page of KAEFER’s website is transmitted in encrypted form is determined by the closed display of the key or lock symbol in the lower status bar of your browser.

In addition, KAEFER also uses appropriate technical and organisational security measures to protect your data against accidental or intentional manipulation, partial or total loss, destruction or unauthorised access by third parties. The security measures are continuously improved upon, in line with technological developments.
