Purpose of data processing

In accordance with the obligation under the German Whistleblower Protection Act (HinSchG), a digital internal reporting office has been set up with the whistleblower system AdvoWhistle. AdvoWhistle is part of the Compliance Management System.

Employees, customers, business partners or other persons providing information can use AdvoWhistle to report suspected violations of laws and internal rules securely and confidentially. This is intended to promote the detection and prevention of significant breaches of rules and to avert considerable risks and damage.


The person responsible for the processing of personal data in the context of an attorney-client relationship is: Bette Westenberger Brink Rechtsanwälte PartGmbB, Große Langgasse 1A, 55116 Mainz, Germany, telephone +49 6131 287700, e-mail (hereinafter referred to as "trusted attorneys").

Responsible for the content are lawyer Stephanie Kappen and lawyer Christian Faber. The company data protection officer of Bette Westenberger Brink Rechtsanwälte can be contacted at the above address and at

Technical Infrastructure

The lawyers of confidence use the whistleblower system software of the technical service provider iComply GmbH, Große Langgasse 1A, 55116 Mainz, Germany.

Personal data and information entered into the system are stored in a database operated by the technical service provider in an ISO/IEC 27001 certified data centre. Access to the data is only possible for the explicitly authorised trusted lawyers. End-to-end encryption of all data, multi-level password protection, technical and organisational measures and regular certification ensure that technical service providers, the data centre operator and other third parties have no access to the data.

Legal basis

The legal basis for the processing of information that falls within the scope of the Whistleblower Protection Act is the legal obligation pursuant to Art. 6 para 1 c) DSGVO in conjunction with Section 10 Whistleblower Protection Act (HinSchG).

The legal basis for the processing of tips relating to breaches of internal rules is the overriding legitimate interest in the detection and prevention of significant breaches of rules and the associated prevention of risks and damage pursuant to Art. 6 para 1 f) DSGVO.

Use of the reporting portal

The use of AdvoWhistle is on a voluntary basis. When submitting a tip-off, AdvoWhistle collects the following personal data and information: 
  • person providing the tip-off: name (if you disclose your identity), contact details (if you provide them). 
  • incident-affected persons: First name and surname, information about incidents and suspected violations of the law and rules.  
  • Witnesses and/or third parties named in the notice (e.g. customers, suppliers, colleagues or business partners): first and last name, contact details.

File attachments may be sent when submitting a report and sending supplements. If anonymity is to be maintained, hidden personal data must be removed before sending. If this is not possible, only the text from these files can be copied into the digital report form, or printouts of these files can be sent to the postal address of the ombudsmen.


Incoming information will be received by a narrow circle of expressly authorised confidential counsellors and will always be treated confidentially. The confidential counsellors examine the facts of the case and, if necessary, carry out further case-related clarification of the facts. Any person who has access to the data is obliged to maintain confidentiality.

For further processing of incoming information, it is regularly necessary to pass on information to the client. If agreed, the lawyer of confidence shall always obtain the express consent of the person providing the information before passing it on.

If the client is domiciled outside the European Union and there are different regulations on the protection of personal data, the lawyer of confidence shall always ensure that the relevant provisions of data protection law are complied with when passing on information.

Information of accused persons

As a matter of principle, the lawyer of confidence is not obliged to inform accused persons that information concerning them has been received, since the exception from professional secrecy under Article 14 (5) d) of the Data Protection Regulation applies to lawyers. The content of the information is collected and processed within the client relationship. 

Data subject rights

Persons whose personal data are processed (data subjects) have the right to receive, upon request and free of charge, information about the personal data stored about them, their origin and recipients and the purpose of the data processing. If we process your data on the basis of our legitimate interest, you have the right to object to the processing if there are legitimate grounds arising from your particular situation (right of objection). 
In addition, data subjects have the right to rectification of inaccurate personal data, the right to erasure of personal data, the right to restriction of the processing of personal data, the right to data portability. 

Data subjects also have the right to complain to a supervisory authority. For this purpose, data subjects may contact the supervisory authority of their usual place of residence or place of work or the confidential counsels.

Retention period of data

The documentation of notices and the personal data contained therein are generally deleted three years after the conclusion of the procedure. In individual cases, the documentation may be kept longer in order to fulfil the requirements under the Whistleblower Protection Act (HinSchG) or other legal provisions, as long as this is necessary and proportionate. A final assessment is also stored for documentation purposes.
