The use of our website is as a rule possible without providing any personal details. Insofar as personal details (for example name, address or email addresses) are collected on our sites, this is always carried out, insofar as possible, on a voluntary basis. These data will not be forwarded to third parties without your explicit consent. We would like to point out that the data transmission in the Internet (e.g. with the communication by e-mail) may feature loopholes in the security. A consistent protection of the data against the access by third parties is not possible. The use of contact details published within the framework of the masthead obligation by third parties for the sending of advertising and information materials which have not been explicitly requested is hereby explicitly objected to. The operators of the sites shall explicitly reserve legal steps in the event of the unsolicited sending of advertising information, for example by spam-mails.
