Our offer contains links to external websites of third parties, on whose contents we have no influence. Therefore we cannot assume any liability for these external contents. The respective provider or operator of the sites is always responsible for the contents of the linked sites. The linked pages were checked for obvious legal violations at the time of the first linking. Obviously illegal contents were not recognizable at the time of linking using a reasonable standard of examination. However, it cannot be ruled out that the contents may be subsequently changed by the respective providers. A permanent control of the contents of the linked pages is not carried out without concrete evidence of a violation of the law. If we become aware of any infringements, we will remove such links immediately.
