It is usually possible to use our website without specifying personal data. If on our websites personal data (for example name, address or e-mail addresses) is collected, this is always done as far as possible on a voluntary basis. This data will not be forwarded to third parties without your express agreement. We draw your attention to the fact that the transmission of data over the Internet (e.g. in e-mail communications) may involve security breaches. It is not possible to protect such data completely from third-party access. The use of contact data published within the framework of the imprint obligation by third parties to transmit advertising and information material which has not been explicitly requested is hereby expressly opposed. The operators of the websites explicitly reserve the right to take legal action in the event of the unsolicited mailing of advertising information through spam mails, for example.
