Legal advisories:

The author accepts no warranty for the currency, correctness, completeness, or quality of the provided information. No liability is accepted for any material or immaterial loss incurred directly or indirectly through the use of or failure to use the information provided here or through the use of erroneous or incomplete information, unless there is evidence of intent or gross negligence. The provider reserves the right to modify, supplement, vary, and delete all or part of the web presence or range of offers without prior notification and to discontinue their publication over a definite or indefinite period.

References and links:
In accordance with § 5 Para 1 MDStV, we accept responsibility for “our own contents” provided here. These contents differ from the contents of other providers that are accessed via so called links (§ 5 Para 2 MDStV). These links constitute dynamic references at all times. Links are provided after the external contents have been examined once only. It is, however, impossible to monitor external contents. It cannot be ruled out that a reference of this kind may theoretically point to an offer that has since become unlawful, and individual cases cannot be avoided in practice. We therefore dissociate ourselves explicitly from the content of linked addresses that have afterwards been modified. Should there be reason to believe that an actual offer linked from this site has become unlawful (as defined under § 8 MDStV), the link to the offer will be removed immediately.

Copyright and trademarks:
Illustrating references to third party contents with text or images depends on the offer when no text or image is deemed suitable from own production.

The layout of the homepage, the graphics used, and the other contents are copyrighted.

When the web offer allows the entry of personal or business details (email addresses, names, addresses), the user discloses these details explicitly on a voluntary basis.

Legal validity of this disclaimer:
This disclaimer must be regarded as a constituent of this web offer and refers to this page. When individual wording or parts of this text do not comply, no longer comply, or not fully comply with the current legislation, the content and validity of the remaining text in this document remain unaffected.
