In most cases our website can be used without the need for you to disclose your personal data. We draw your attention to the fact that security gaps may affect the transfer of data on the internet (e.g. when communicating by email). It is not possible to guarantee absolute protection of data against access by third parties. Explicit objection is here made to the use by third parties of contact data published in accordance with legal requirements for the purpose of sending advertising and information material which has not been explicitly requested. The operators of this website explicitly retain the right to take legal action in the event that unsolicited advertising information, such as spam mail, is sent.
