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.
