Most of our ser­vices do not require any form of regis­tra­tion allo­wing you to visit our web­site without pro­vi­ding per­so­nal infor­ma­tion. Howe­ver, some ser­vices may require regis­tra­tion. The pro­vi­sion of any per­so­nal data (such as name, address, or email address) remains optio­nal. Your data will not be pas­sed on to third par­ties without your con­sent. We also point out that data trans­mis­sion over the Inter­net (such as when com­mu­ni­ca­ting via email) can have secu­rity gaps. Please be aware that the Inter­net is gene­rally not a secure envi­ron­ment and no data trans­mis­sion over the Inter­net can be gua­ran­teed totally secure. The­re­fore, a com­plete pro­tec­tion of data against unaut­ho­ri­zed access by third par­ties is not pos­si­ble. In addi­tion, we her­eby expli­citly oppose to the use of publis­hed infor­ma­tion under the imprint obli­ga­tion by third par­ties for sen­ding unso­li­ci­ted adver­ti­se­ments and infor­ma­tion mate­ri­als. The ope­ra­tors of these pages expressly reserve the right, in case of unso­li­ci­ted pro­mo­tio­nal infor­ma­tion, such as spam e-mails, to con­sider and initiate legal action.
