Question to the data protection officer

If you have any questions about data protection, please email us or contact the person responsible for data protection in our organization.

Collecting and processing personal data

These contact data include, for example:

  • Contact details from your business card that you have given to a member of our company,
  • Contact data that we have received from you by letter, telephone, fax or e-mail,
  • Contact details with your name, which we have received from your company (for example from sales, purchasing, your superior or one of your colleagues) on the basis of an existing contractual relationship,
  • Contact details with your name, which we have taken from your employer’s Internet homepage,
  • Further ways of handing over contact data are possible, for example also the simple note on paper during a conference or trade fair or over the participant list of a seminar.

Purposes and legal basis for the processing of personal contact data:

  • In the case of an existing contractual relationship: the execution and execution of this contractual relationship. If other contacts already exist and your contact details are supplemented, this is done to improve or optimise communication in the business relationship of the current contract.
  • The existing contractual or other business relationship provides the basis for permission to process the personal data, which is necessary, appropriate and expedient for the processing of the same.
  • If no contractual relationship exists: For the purpose of initiating and establishing a business relationship and, if applicable, a contractual relationship.
  • In the latter case, the basis for permission is the legitimate interest of the responsible party in initiating new business relations. When weighing up the rights of the persons concerned, it is established that any interests of the persons concerned do not outweigh the confidentiality of their contact data, because if this were the case, we assume that we would not have received the contact data from you or your employer.

Planned data transmissions and planned or possible recipients of personal contact data:

  • If necessary, we will only forward the contact data to other parties within the company who have a legitimate interest in contacting you.
  • Your contact details will not be transferred to countries outside the EU (“third countries”).


Should exceptions to this information become necessary due to legal or official requirements, then we would, as far as the respective legal basis permits, contact you beforehand before passing on the contact data according to a request made.

If we use address data we collect ourselves for advertising purposes:

  • In this case, we will only use your personal contact data if your name has been stated on the Internet homepage or in an advertising contribution or another medium in the presentation of your company for the purpose of establishing contact.
  • If your e-mail address has been entered on the Internet homepage or another of the media mentioned for the purpose of contacting you, we assume that we may also contact you by e-mail, including for the purpose of advertising.
  • If an address from company presentations is used without giving names for the establishment of contact, we will write to the company without mentioning a name, i.e. without reference to a person, as a “legal person”.

Duration of storage of personal contact data:

  • In the case of an existing business relationship (contractual relationship or contract-like relationship), we store your personal data at least for the duration of the existing contractual relationship or until your name as contact person in this matter is replaced by another name by your company, which then takes over your role.
  • If, after conclusion of the business relationship, documents such as offers, individual agreements for order execution and invoices in accordance with the German Commercial Code (HGB) and the Tax Code (Abgabenordnung) must be kept for a period of 6 or 10 years, then these retention periods are binding for the complete documents, even with any names still mentioned on them. Following these retention periods, these data are deleted and paper documents are destroyed in accordance with data protection regulations.

Contacts in the e-mail directory of our employees:

  • In addition to internal electronic directories of business partners’ contact persons, your contact data may also be available in the e-mail directories and similar personal directories of our employees. With the technology available today, these are not subject to deletion monitoring and are not always stored sorted by company (so they cannot be deleted as a stack).
  • We would also like to draw our employees’ attention to the deletion of a company’s contacts from their personal directories once the business relationship has expired.
  • Due to the well-known uncertainty of this procedure with the available technology of personal contact directories, we would also like to ask you to help us by writing to the existing contact partners in our company upon termination of the business relationship or termination of your responsibility as a contact person for us and asking for deletion of your contact data in all personal directories (e-mail directories and similar on the PC and in the smartphone).

Your rights as a data subject:

  • You have the right to information about the data we have stored about you.
  • In case of errors in the name or changes of address you have the right to request the correction.
  • You have the right to object to the use of your personal contact data for the purpose of advertising by us.
  • The right of objection does not apply to letters which are necessary in the context of the existing business relationship and as long as you are a contact person in your company.
  • You have the right to request the deletion or blocking if the business relationship no longer exists and there are no longer any storage obligations (as stated above) or if your function as contact person within the scope of our business relationship has been replaced by another person in your company.

Revocability of consents:

If our use of your personal contact data for the purpose of advertising is based on the legal basis of a consent, you have the right to revoke this consent for all future uses. The revocation can no longer affect actions that have already been initiated, but for future actions.

Right of appeal to the supervisory authority:

If, despite all our efforts, you wish to complain to the Data Protection Authority about good information and the confidential treatment of all your personal data, this is your right and you can contact the Data Protection Authority responsible for you or us directly. The addresses of the data protection supervisory authorities of the federal states can be found here.

Obligation to provide personal contact data:

As long as your employer has designated you as a contact person for us, you are contractually obliged to provide us with your contact details and any changes to these details. Non-provision may result in the infeasibility of the contractual benefits in the contractual relationship with your employer’s company.

Automated decisions:

Automated decisions pursuant to Art. 22 DSGVO or other profiling measures pursuant to Art. 4 No. DSGVO do not take place.
