§8th Order Cancellation

    1. Client has the right to cancel the respective Individual Order. If OPTILYZ has already incurred costs at this point due to the order (e.g. due to the fixed commissioning of third parties or the ordering of consumables), the Client has to reimburse OPTILYZ for these costs in full.

    3. A cancellation of the order by the Client must be in text (e-mail).


    1. The services of OPTILYZ are services under German law. Success is only owed in the case of taking over production services according to the Client’s specifications.
    2. If Client is entitled to warranty claims against OPTILYZ due to defects of the item or the work in case of conclusion of an Individual Order based on obligations under a contract for work and services or a contract on the delivery of services, the limitation period for warranty claims shall be one (1) year from delivery of the item in case of a contract on the delivery of services, and one (1) year from acceptance in case of a contract for work and services.

      otherwise in the respective Individual Order.

    5. Any claim that the Transfer has not been carried out by the agreement must contain the exact circumstances giving rise to the complaint. Such complaints must always be made in writing (e-mail or message via the contact form on the OPTILYZ Platform is sufficient). Sec. 377 of the German Commercial Code (Handelsgesetzbuch) shall apply mutatis mutandis to the assertion of a claim for non-contractual performance of the Transfer of addressed advertising mail by the Client.
    6. If no complaint is made within this period, the goods/service are deemed to have been accepted by the Client. Complaints after this period, especially in case of an obvious defect, can be rejected by OPTILYZ.

§ 10th Liability

    1. OPTILYZ shall be liable for all damages caused intentionally or by gross negligence, which areis the consequence of the non-existence of a guaranteed quality of the subject of performance, which is the consequence of a culpable injury to health, body or life, or for which liability is provided for under the Product Liability Act (Produkthaftungsgesetz), by the statutory provisions.
    2. In case of breach of cardinal obligations OPTILYZ shall also be liable in case of slight negligence. Cardinal obligations are such contractual obligations, the fulfillment of which enables the proper execution of the contract in the first place and the observance of which the other party to the contract may regularly rely on, and the violation of which endangers the achievement of the purpose of the contract on the other side. If there is no case of § 10 No. 1, the liability, in this case, shall be limited to such damages, the occurrence of which must be typically and foreseeably expected in the context of the provision of services such as contractual services. Irrespective of this limitation, liability is limited to an amount of EUR 3,000,000.00 (in words: three million euros) per case of damage. This also includes the reimbursement of futile expenses.
    3. Apart from that, liability for direct and indirect damages (loss of profit, consequential damages) – irrespective of the legal ground – of OPTILYZ as well as of its vicarious agents and assistants is excluded.
    4. The limitation period for claims for damages against OPTILYZ shall be one (1) year except in the cases of § 10 No. 1.

    4. If any provision of these T&Cs is or becomes void, invalid, unenforceable, or unenforceable – in whole or in part (each a “Faulty Provision”), the validity and enforceability of the remaining provisions of these T&Cs shall not be affected thereby. The Parties already now agree, to reach a mutual understanding in the future to replace the Faulty Provision by a provision which, to the extent legally possible, comes as close as possible to what the parties would have agreed on by the spirit and purpose of this Agreement if they had recognized the faultiness of the provision.
