The concept of personal data is defined in the Basic Data Protection Regulation (DSGVO). According to this, "personal data" is all information relating to an identified or identifiable natural person.

Privacy and the protection of personal data, i.e. any information about personal or factual circumstances which determine or make determinable the user as a natural person during the use of our Internet pages, have the highest priority. We assure that we treat personal data confidentially and in accordance with the statutory data protection regulations and this data protection declaration. The mere use of our Internet pages does not constitute a contractual relationship between users and us as the provider.

Collection and processing of data
We collect information from users who wish to receive further information from us regarding our consulting services, who are looking for employment opportunities or who register for events. When filling out these contact forms, users are asked to provide only appropriate data as a so-called "mandatory field". Additional, voluntary information is used to evaluate and respond to enquiries and requests as required.

In addition, anonymous data is used to adapt our Internet pages to the needs of visitors. We may collect demographic information and information about the systems and browsers that visitors to our site use to provide optimized ads for responsive design and to learn more about website users, identify areas of interest, identify usage patterns, improve user value, and verify that pages are designed to match the device preferences of most visitors.

Without the user's consent, we do not pass on any data to third parties that are not directly connected with the user's request. Only in this case may data be passed on to service providers who work for us and who have access to the data in connection with this activity in order to process user requests and requests.

Duration of data usage and data retention
Data will be deleted or blocked as soon as the purpose of the data use has been achieved or no longer applies. Any further storage of data will only take place if we are legally obliged to do so. After the expiry of applicable legal storage periods, the corresponding data will be routinely deleted or blocked in compliance with the applicable data protection regulations. If users have consented to a longer period of storage, processing and use of the data, the data will be deleted or blocked after expiry of the respective period or upon revocation of the corresponding consent.

Copyright and ancillary copyrights
Contents published on our Internet pages are subject to German copyright and ancillary copyright law. Any use not permitted by German copyright and ancillary copyright law requires the prior written consent of us or the respective copyright holder. This applies in particular to duplication, editing, translation, storage, processing or reproduction of content in databases or other electronic media and systems. Contents and rights of third parties are marked as such. The unauthorized duplication or passing on of individual contents or complete pages is not permitted. The presentation of this website in external frames is only permitted with written permission. A linking of our sides is to be co-ordinated before.

External Links
Our Internet pages contain links to pages of third parties ("external links"). These Internet pages are subject to the liability of the respective operators. As a provider, we have checked whether there are any legal violations when external links to external content were first established. At that time, no violations of the law were apparent. We have no influence whatsoever on the current and future design or content of the linked pages. The inclusion of external links does not mean that the provider adopts the content behind the reference or link as his own. A permanent control of the external links is not reasonable without concrete evidence of legal violations. However, if we become aware of any violations of the law, such external links will be deleted immediately.

Social Networks
On some pages of the Kerkhoff Group and its subsidiaries, links to social networks are provided for a comment function, which are marked accordingly.
No information is transmitted to social media service providers via our Internet pages. Only when this comment function is used are users forwarded to the Internet pages of the respective provider and user information is thereby transferred to the respective third party provider.
