ZENITH lingo is not liable or responsible for any failure to perform, or delay in performance of, any of its obligations that is caused by Force Majeure events (natural disasters such as hurricanes, earthquakes, or floods; fires, explosions, epidemics, pandemics, wars, strikes, riots, demonstrations, political unrests etc.).

A Force Majeure Event includes any act, event, non-happening, omission or accident beyond ZENITH lingo’s reasonable control.

ZENITH lingo’s performance is deemed to be suspended for the period that the Force Majeure Event continues, and it will have an extension of time for performance for the duration of that period. ZENITH lingo will use our reasonable endeavors to bring the Force Majeure Event to a close or to find a solution by which its obligations may be performed despite the Force Majeure Event.


ZENITH lingo is only liable for damages in the event of intent and gross negligence. ZENITH lingo is also liable for the negligent violation of essential contractual obligations (cardinal obligations), d. H. such duties the violation of which jeopardizes the achievement of the purpose of the contract and compliance with which a contractual partner may regularly trust. In case of a breach of material contractual obligations, however, ZENITH lingo is liable only for damage typical for the type of contract that was foreseeable at the time of conclusion of the contract.

The above exclusions of liability do not apply in the event of an infringement of life, body, and health. Liability under the Product Liability Act remains unaffected. An exclusion or limitation of ZENITH lingo’s liability also applies to the personal liability of its legal representatives, employees, and other vicarious agents.


Amendments and supplements to the contract must be only in writing. Should one of the above provisions be ineffective, ZENITH lingo is entitled to replace it with an effective provision with a similar purpose. If this is not possible, the statutory provisions apply.

German law shall apply, excluding the UN law on the international sale of goods (CISG). For consumers, this choice of law applies only insofar as it does not exclude the protection afforded by mandatory provisions of the law of the state of the consumer’s habitual residence.

In case of disputes concerning the meaning or interpretation of a provision of the English version of these terms and conditions, the German version shall prevail in case of doubt.

Jurisdiction is the seat of ZENITH lingo, Mainz, as far as the customer is not a consumer, but a merchant, legal entity of public law or special fund under public law or if the customer has relocated his domicile or habitual residence abroad after conclusion of the contract or his domicile or habitual residence at the time of filing the action is known.
