Semanux GmbH, located at Abraham-Wolf-Strasse 56, 70597 Stuttgart, Germany ("Semanux") specializes in innovative multimodal computer controls supported by artificial intelligence and offers the Semanux Access software.

The customer intends to use Semanux's computer control software for private or business purposes. To enable the customer to use the software, the customer is granted a non-exclusive, non-transferable, time-limited right to use the software in accordance with these terms of service ("Terms of Service").

The Terms of Service can be viewed and printed out at any time on Semanux's website at The customer is independently responsible for saving the text of the contract at the time the contract is concluded. No copies will be provided by Semanux after the fact.

1.1 Subject to these Terms of Service and the service description, Semanux grants customer access to the subscribed products in accordance with the service description and applicable documentation for the term of this agreement.

1.2 The customer shall pay Semanux the agreed remuneration as specified in the online purchase process or in the order form, insofar as the customer receives services that are marked as subject to a charge upon conclusion of the contract.

2.1 The Semanux Access software for the innovative, multimodal control of computers by means of head movement and voice input ("Software") is an offer of Semanux GmbH (hereinafter: "Semanux" or "we").

2.2 These Terms of Service shall apply to the contractual relationship between Semanux and the User (hereinafter: "User" or "you") regarding the use of this offer. Deviating Terms of Service or deviating conditions of the User shall not become part of the contract, even if Semanux does not expressly object to them.

3.1 The requirement for the use of Semanux's offer (paid subscriptions and/or free trial offers) is the registration of the User at Semanux. Semanux may offer a free trial of Semanux's service either independently after the free registration or in connection with the conclusion of a contract for a paid subscription. Notwithstanding any agreements to the contrary, there shall be no entitlement to a free trial.

3.2 The contract shall come into existence upon confirmation of the User's registration with Semanux ("Registration"). Semanux may also declare confirmation of the registration or acceptance of the User's order by activating the respective offer. The order of a paid subscription shall be confirmed by Semanux in accordance with the statutory provisions; this order confirmation shall not constitute acceptance of the order.

3.3 Semanux shall not store the terms and conditions of the contract for the User, without prejudice to the fulfillment of the statutory information obligations.

3.4 The User must have full legal capacity or act with the consent of his legal representative. In any case, the User must be at least 18 years old.

3.5 Semanux reserves the right to amend these Terms of Service even after conclusion of the contract with effect for existing contractual relationships, provided that this appears necessary to safeguard the legitimate interests of Semanux, is not unreasonable for the User and the User is not disadvantaged thereby contrary to good faith. Semanux shall consider changes to be reasonable that (i) are exclusively beneficial to the User, (ii) are necessary due to purely technical changes, (iii) are necessary due to a change in the applicable or newly introduced legal situation, (iv) must be made due to a court decision or official order against us, or (v) insofar as we introduce additional services, services or service components that require a service description in the Terms of Service. Explicitly excluded from the foregoing right to make changes are changes that result in a change in the character of the main contractual service owed by us that is disadvantageous to the User. To this end, Semanux shall inform users of the changes in text form at least four weeks before the new terms and conditions come into effect. Users shall have the opportunity to object to the changes. In this case, both parties shall have an extraordinary right of termination. If no objection is made, the changes shall be deemed approved four weeks after receipt of the notification. Semanux shall inform the User of the right to object and the effect of silence in the notification. The User's right of termination pursuant to clause 7 shall remain unaffected.

4.1 Insofar as a paid subscription agreement has been concluded, Semanux shall provide the agreed services. Insofar as Semanux also provides content and/or services voluntarily and free of charge, it shall do so without assuming any legal obligation. Semanux shall be entitled to change, expand or limit these services at any time.

4.2 The use of the agreed content of Semanux is generally permitted to the User geographically limited to the territories of the European Economic Area, the Swiss Confederation and the United Kingdom. With the entry into force of Regulation (EU) 2017/1128 of the European Parliament and of the Council of 14th June 2017 on the cross-border portability of online content services in the internal market on 1st April 2018, the use during a temporary stay of the User in another territory is also permitted, provided that the prerequisites specified in Regulation (EU) 2017/1128 for this are met and the customer previously tolerates and enables the (also repeated) verification of its member state of residence in accordance with Regulation (EU) 2017/1128 and the applicable data protection provisions.

4.3 Semanux guarantees an availability of 99% or higher, based on the calendar year, for the server for downloading the Software (this currently corresponds to the Semanux website) as well as for the server for registration and/or obtaining licenses. Not included are downtimes caused by necessary maintenance work, force majeure, technical disruptions of the Internet or other reasons for which Semanux is not responsible.

4.4 Semanux assumes no obligation to back up data for the User and makes no representations, warranties or guarantees beyond those required by law, unless otherwise agreed in individual cases.

5.1 The User may use Semanux's offer exclusively for the agreed purpose, whether private or business. In particular, the customer may not use the data, information or services provided to him/her for the following purposes without the express written consent of Semanux and shall not permit third parties to do so:

(a) the operation of critical infrastructure such as power and water generation and supply, military and defense facilities, and medical equipment;

(b) for environmental control, if physical or economic damage could follow from this (such as hobs);

(c) for controlling automobiles and other vehicles, including electric wheelchairs;

(d) for all illegal activities, especially circumvention of export control laws and regulations.

(e) to the production of programs, writings and the like, if thereby rights of third parties are injured;

(f) for decompiling and reverse engineering the program code.

5.2 The User undertakes to provide truthful and complete information upon registration and to keep this information up to date during the term of the agreement by adjusting it or notifying Semanux.

5.3 Only one registration may be maintained per person at any one time.

5.4 The User is obliged to keep his access data secret and not to pass it on to third parties. The transfer of the possibility of use, the registration and/or a paid subscription to third parties is prohibited.

5.5 The User is obliged to observe the statutory copyrights and other rights existing for the contents of the paid subscriptions as well as for the other contents in the Semanux offer. The User may not reproduce, distribute or make publicly available such content or remove technical protective measures or copyright or legal notices unless this is expressly permitted.

6.3 We may occasionally offer gift cards and vouchers that can be used as a payment method.

6.4 The User shall only have a right of set-off if his claim against Semanux has been legally established, is undisputed or has been acknowledged. The User shall only have a right of retention if its counterclaim is based on the same contractual relationship.

6.5 If the User unjustifiably fails to meet his or her due payment obligations to Semanux, Semanux may, after prior warning and taking into account other legal and contractual rights, temporarily block the User's access until the payment owed has been received. The temporary blocking shall not affect the term of the contract. User may incur late payment charges and interest.

6.6 The User shall, in accordance with law, reimburse Semanux for any damages and necessary expenses incurred as a result of non-payment or late payment by the User or other disruption of payment by the User, unless the User is not responsible therefor.

7.1 The paid subscription contract is valid for a certain minimum term. For example, it can be one (1) month or one (1) year, based on user's choice. At the end of each subscription period, the subscription will be automatically renewed depending on the term of the subscription period unless terminated by User before the last day of the current subscription period.

7.2 The User or Semanux may terminate the contract at any time, with one day's notice before the end of the minimum term. The User may continue to use the Semanux service until the end of the minimum term. If the contract is not properly terminated by the end of the minimum term, it will be automatically renewed and a paid subscription will be activated.

7.3 For the effective termination, the text form is required. The User may also give notice of termination online via the function provided in the Semanux Account. User can always contact us at for help with ending their subscription.

7.4 The right of both contracting parties to terminate for cause in accordance with the law shall remain unaffected. Semanux shall have an extraordinary reason for termination if the User provides misleading information during registration or ordering or has repeatedly violated the Terms of Service. The prerequisite for this is that Semanux has previously warned the User unsuccessfully in order to demand compliance with the contractual obligations.

7.5 If Semanux offers a free trial period for a paid subscription and this is agreed with the User, the agreed contract term of the paid subscription shall be extended accordingly. In this case, the extended period shall apply first (with an ordinary special termination right of the User, if applicable, if agreed) and thereafter the regular term of the paid subscription.

7.6 Within a free trial period, User and Semanux are allowed to terminate the contract at any time with immediate effect.

7.7 In the event of an act with fraudulent intent, a severe, persisting, imminent or repeated material breach of these Terms of Service, Semanux is entitled to suspend the User's access to the Software immediately and indefinitely. User is informed in writing (e-mail is sufficient). The suspicion of fraudulent intent is sufficient.

8.1 Semanux shall in principle only be liable for damages to the User if (1) Semanux, its legal representatives or vicarious agents have caused such damages intentionally or through gross negligence or (2) this is based on a breach of duty by Semanux or one of its legal representatives or vicarious agents that results in injury to the life, body or health of the User. In cases of liability under the German Product Liability Act (Produkthaftungsgesetz, ProdHaftG), the assumption of a guarantee or due to fraudulent misrepresentation, as well as the breach of an obligation the fulfillment of which makes the proper execution of the contract possible in the first place and on the fulfillment of which the User may regularly rely (so-called cardinal obligation), Semanux shall be liable without limitation in cases (1) and (2) of the preceding sentence. Otherwise, liability shall be limited to the foreseeable damage typical for the contract.

8.2 In all other cases not mentioned in (1) and (2) above and except as provided in the following paragraph, Semanux's liability shall be excluded regardless of the legal ground.

8.3 The above limitations of liability apply accordingly to all employees and vicarious agents of Semanux and do not affect the statutory burden of proof. Please note that the statutory provisions shall remain valid.
