9. Concluding provisions
German law applies to the legal relationship between DEVELOPER and You as
well as to the respective terms and conditions. Place of jurisdiction for
both parties is - in so far as permitted by law - Munich (Germany). If You
are a consumer and are not resident in the European Union, Munich is also
the place of jurisdiction. In dealings with consumers in the European Union,
the law at the residence of the end user may also apply if mandatory provisions
under consumer law are concerned.
You have no right of offset unless the claim is not in dispute or has been
determined with legal effect by a court of law. If You are a businessman
within the meaning of the Commercial Code or a body under public law, then
the place of fulfilment for deliveries and payments and the place of
jurisdiction are Munich.
If any part of these Terms of Service is held to be invalid or unenforceable
under any applicable statute or rule of law, the unenforceable part shall be
given effect to the greatest extent possible and the remainder will remain
in full force and effect.
DEVELOPER may include Licensee's company name and logo in a publicly available
list of customers and in its public communications.
