§ 8 Rights of candena to User Content

The User grants candena and the cooperation partner OECD a perpetual, non-exclusive, worldwide, transferable, sublicensable right to use any content (including photos, essays, drawings, etc.) that the User creates and stores in the Service for the purposes and the further development of the Service or any future forms of the Service.

This clause shall survive any termination of this agreement.

§ 9 Liability

In the event of a breach of material contractual duties (cardinal duties), candena will be liable for reimbursement of expenses and damages (together: “Damages”). Cardinal duties are all duties, the breach of which endangers the achievement of a contract’s purpose, as well as all duties, the fulfillment of which enables the proper performance of the contract in the first place and on compliance with which the User may generally rely. However, if the breach of a cardinal duty was merely due to slight negligence and did not lead to injury to life, limb or health, claims for Damages will be limited in amount to the typical foreseeable damage.
candena will additionally bear liability in cases of intent and gross negligence, for injury to life, limb or health, or if it has assumed a guarantee, as well as in all other cases in which liability is mandatory by law, in each case in accordance with the statutory provisions.
Otherwise, claims against candena for Damages – regardless of their legal basis, in particular due to a breach of duties arising from these Terms by candena, its legal representatives, employees or vicarious agents, under section 311a German Civil Code (BGB) or due to tort - are excluded.
To the extent candena’s liability is limited or excluded under the above provisions, this will also apply for the personal liability of its legal representatives, employees and vicarious agents.
None of the above shall limit the application of any statutory limitations of candena’s liability (e.g. sec. 521 of the German Civil Code/ Bürgerliches Gesetzbuch).

§ 11 Confidentiality

The User undertakes to maintain confidentiality with regard to any and all confidential information to which the User receives access in connection with the use of the Service. Confidential information is information that is either marked by candena as protected or confidential or otherwise designated as such in writing, or information that, given the circumstances of its disclosure, the User can reasonably recognize as confidential evident. Confidential information comprises in particular, but not only, the Access Data (paragraph 2 of these Terms).
The above obligation to maintain confidentiality will not apply if and to the extent the information in question demonstrably (i) is public knowledge or becomes public knowledge without the User having been at fault or violating this secrecy obligation, (ii) is or becomes state of the art, (iii) was already known to the User at the time it was conveyed, which must be proven by documents evidencing such knowledge, (iv) was or is later lawfully made known or accessible to the User by a third party, (v) must be disclosed on the basis of statutory provisions or enforceable official orders or judicial decisions.

§ 14 Miscellaneous

1) The English version of these Terms shall prevail over any translations into other languages. These Terms of Use are governed by the laws of the Federal Republic of Germany to the exclusion of provisions on international private law and the United Nations Convention on Contracts for the International Sale of Goods (CISG). Regarding consumers resident in the European Union, the relevant laws of the country in which they reside may also be applicable, provided that those provisions mandatorily apply and concern consumers’ rights. The language of contract is English. As far as legally permissible, the exclusive legal venue for all disputes shall be Lüneburg, Germany. Should individual provisions of these Terms be or become invalid or unenforceable, this shall not affect the validity of the remaining provisions. The invalid or unenforceable provision shall be replaced by a provision that comes as close as possible to the economic purpose of the invalid or unenforceable provision. In the case of an omission, that provision shall be deemed to be agreed upon which would have been agreed upon, according to the purpose and meaning of these Terms of Use, had the parties considered the matter from the outset. candena shall have the right to transfer these Terms to a third party without the User's consent, provided that such third party accepts to be bound by the provisions of these Terms.

2) We reserve the right to modify these T&C at any time. We shall inform you whenever such modifications are made. You are deemed to be in agreement with the modifications if you do not provide objection within (4) weeks of being notified thereof. In notifying you of modifications, we shall also explicitly inform you of this consequence of not rejecting the changes. Should you not agree to the changes, the contractual relationship will continue to the previously applicable conditions until it expires, or can be terminated by us. Should you wish to return to use of the Service, you will only be eligible for use under the conditions that are current at that time.

3) We are entitled to transfer, with exempting effect, all of the duties and obligations covered by these T&C, entirely or partially, to a third party. You hereby already agree to such transfer of contract. You have the right to extraordinarily terminate your contract immediately should we avail ourselves of such a transfer.

4) If you have no place of general jurisdiction in Germany or another EU member state, or if you have moved your place of permanent residence to a country outside the EU since these general terms came into effect, or if your domicile or the place you usually reside is unknown at the time at which the lawsuit is commenced, the exclusive place of jurisdiction for all and any disputes arising from this contract shall be the place of business of Candena. The same applies if the contract partner is a merchant, a legal entity under public law or a public fund.
