The KURZ TRUSTCONCEPT® CHECK Application (hereinafter 'App') will be provided to you by LEONHARD KURZ Stiftung & Co. KG (hereinafter 'Licensor') subject to the following 'Terms of Use':

By logging in, or, where a log-in is not required, by starting to use the app the validity of these Terms of Use is accepted in their then current version.

Any rights not expressly granted by these Terms of Use are reserved by the Licensor.

The use of the App is free.

The App is a software application specifically adapted for mobile devices for verifying product codes. The App verifies whether such product codes are known in the data base and returns the result of the verification process back to the respective users of the App (hereinafter 'Licensee').

  1. The Licensor grants the Licensee a non-exclusive, non-sublicensable, non-transferable right to use the App on a mobile device supported by the App and owned by the Licensee or otherwise lawfully in his possession to install and use the App for the sole purpose set out in Section 1.
  2. The license granted by the Licensor is subject to any obstacles arising out of national or international foreign trade and customs requirements or any embargos and/ or other sanctions, set out in particular in Section 8.
  3. This license agreement shall also apply to any updates or upgrades to the App, which are provided by the Licensor unless such update/upgrade is subject to a separate license agreement.

  5. Any breach or the attempted breach of the obligations of this Section 2 may be prosecuted and may be subject to claims for damages.
  6. Licensor reserves the right to modify these Terms of Use. Changes to these Terms of Use will be effective when the Licensee expressly agrees or when they were brought to the attention of the Licensee notice and the Licensee does not object within 10 days.

  7. This license shall not affect any third party rights. The Licensee shall not be entitled to remove, modify or obliterate any ownership and copyright notices, serial numbers, version numbers or trademarks.
  8. The license agreement does not require the Licensor to create or maintain any services that run outside the App. In particular, the Licensor is not obligated to provide or maintain any services (e.g. software, storage space or database) in the IT infrastructure of the Licensor or any third party even if such IT infrastructure is necessary for the full-featured use of the App.
  9. Trademarks, brand names and other contents may not be modified, copied, reproduced, sold, rented, used, supplemented or otherwise exploited without the prior written consent of the Licensor.

  1. Licensor may at any time suspend or discontinue the provision of the App and/or the services necessary for the performance of the App in whole or in part. Due to the nature of the internet and computer systems, the Licensor does not warrant the continuous availability of the App. Since the App is provided free of charge, any liability for material and legal defects of the App, particularly for the accuracy, correctness, non-infringement of third party rights, completeness and/or usability – except in the case of intent or fraudulent concealment of a material and/or legal defect of the App shall be excluded.
    Licensor shall endeavor to keep the App free of viruses, Trojans, spyware or other malware, but cannot give an unrestricted warranty for that matter. Before downloading the App, the Licensee shall, for his own protection and to prevent viruses and other malicious software on the App use appropriate security measures and virus scanners.
  2. In no case Licensor shall be liable for defects after the change of operating conditions (hardware/software environment), after installation and operating mistakes as far as these are not due to a faulty user manual, after interferences with the App, such as changes, adjustments and/or connections with other software or in case of defects which occurred after a non-contractual use, unless the Licensee can prove that the defect already existed at the time of acceptance or that there is no causal connection between Licensee’s use and the defect. Liability under the provisions of the Product Liability Act remains unaffected.

Licensor is liable in cases of willful misconduct, bodily injury and in case of liability under the Product Liability Act. In all other cases, liability of the Licensor is excluded.

Licensee acknowledges and confirms that he is not a resident or is situated in a country, which is subject to an embargo of the Federal Republic of Germany, the European Union, the United Nations or the US government, or which the Federal Republic of Germany, the European Union, the United Nations or the US government have been classified as a 'terrorism-supporting country' or which is on a list of the Federal Republic of Germany, the European Union, the United Nations or the US government regarding export bans or restrictions. The Licensee must always comply with all applicable national and international (re-)export control law. The Licensee shall indemnify the Licensor against any and all claims by public authorities or other third parties due to the non-observance of the above legal obligations with regards to export controls in full and undertakes to reimburse all costs, damages and expenses incurred by Licensor in this context, unless the Licensee is not responsible for the breach of duty. This shall not imply a change in the burden of proof to the detriment of the Licensee.

If the Licensee does not meet the license agreement, the license rights as of Section 2 shall cease automatically and without further notice by the Licensor. The right for either party to terminate the license agreement without notice on exceptional reasons (termination for cause) remains unaffected. Such exceptional reasons shall be considered as, but not limited, to a breach by the Licensee of the obligations in Section 5. In case of a termination for cause, the Licensee shall immediately cease the use of the App and delete the App completely and confirm such deletion to the Licensor in writing.

If any provision of these Terms of Use is held invalid or unenforceable for any reason, such provision is fully separable and shall thereupon be separated from the remaining provisions of the Terms of Use and the remaining provisions are nevertheless valid and enforceable as if such parts of the provisions held invalid or unenforceable were not part of the Terms of Use.

Neither Licensor nor Licensee shall assign or otherwise transfer the rights resulting from this Terms of Use or any part thereof without the other party's prior written consent and any purported assignment or transfer without such consent shall be void and of no force or effect.

German substantive law shall apply exclusively. The United Nations Convention on Contracts for the International Sale of Goods of 11 April 1980 shall be excluded.
The exclusive place of jurisdiction shall be Nuremberg, Germany.
