  1. Opinions expressed on HIIK blogs are solely those of the author or commenter, not of HIIK, which takes no institutional positions.
  2. Although the information contained on this website is assembled with utmost care, errors and ambiguities cannot be completely ruled out. Therefore HIIK cannot be held liable for the timeliness, correctness, completeness or quality of the information provided.

Our website contains links to external websites of third parties. As these websites are beyond our control, we cannot assume any responsibility for their content and privacy policy. Legal liability lies exclusively with the operators of these external sites. The linked sites were checked at the time of linking for possible legal violations. Illegal contents were not visible at the time of linking. A permanent control of the linked pages is unreasonable without concrete evidence of a violation. Once violations have become known, we will immediately remove such links and explicitly distance ourselves from them.

  2. Copying, editing, distribution and any kind of exploitation outside the limits of copyright law requires the written consent of the HIIK.

  4. Should the content on this website not be created by the operator, the copyright of third parties must be respected. In particular contents of third parties are marked as such.
  5. Should you become aware of copyright infringement, we kindly ask to be notified. Upon notification of violations, we will remove the content immediately.
