Terms of Service

These terms apply to Steinkauz Cloud and the publicly accessible Steinkauz AI websites. The contract language and authoritative version are German. Other language versions are translations for information. In the event of discrepancies, the German version prevails unless mandatory law requires otherwise. Mandatory consumer rights remain unaffected.

The provider is Fabian Werling, trading as Steinkauz AI, Salierstraße 7, 67346 Speyer, Germany, email: contact@steinkauz.ai; further details are in the Legal Notice.

1. Scope

  1. Steinkauz Cloud is a software platform for controlled use of language and image models. The service is intended for organisations; natural persons may also purchase it.
  2. A Private Deployment (self-hosted installation) is not covered by these terms unless otherwise agreed.
  3. Conflicting purchasing terms of the customer do not apply unless we expressly agree to them in text form.

2. Formation of the contract

  1. The presentation on the website is non-binding. A contract for Steinkauz Cloud is formed when the order process (including the payment service provider) has been completed successfully and we confirm the order.
  2. Orders may be placed by persons who have a user account and are authorised to act for the respective organisation (usually the owner role).
  3. We may reject orders, particularly in cases of inability to pay, sanctions listings or abusive use.

3. Service

  1. We provide the platform (account, organisation, chat, Platform API, controls and records) as software as a service.
  2. Inference is not included in the fee. Model calls use keys or endpoints supplied by the customer (BYOK) or a gateway operated by the customer. The customer pays model providers directly for their charges.
  3. Availability, features and usage limits (such as requests, concurrent streams, retention and storage) are determined by the service description displayed when the contract is concluded. Statutory rights concerning defects remain unaffected.
  4. We may modify the service for valid reasons, particularly to adapt to changed technical requirements, improve security or implement legal requirements. Consumers incur no additional costs as a result and are clearly informed of changes. Changes that impair accessibility or usability will be announced reasonably in advance on a durable medium, specifying their features, timing and statutory termination rights. The statutory requirements and rights under section 327r of the German Civil Code (BGB) remain unaffected.

4. Customer obligations

  1. The customer keeps access credentials confidential and chooses secure authentication.
  2. The customer ensures that supplied keys, endpoints and content may be used lawfully and that the organisation has the necessary legal basis for personal data.
  3. The customer enters into the Data Processing Agreement with us where we process personal customer content in the cloud.
  4. Prohibited conduct includes attacks on the service, bypassing access controls, bulk extraction, use for unlawful purposes and sharing access with unauthorised persons.
  5. The customer is responsible for managing the organisation's members and API keys.

5. Fees, taxes and trial period

  1. Steinkauz Cloud is offered as a monthly subscription in euros. The total price, including applicable VAT, displayed before the order is placed is decisive. Business offers may additionally show net prices.
  2. Providing a VAT identification number is optional. If a valid VAT identification number is available and the requirements for an intra-Community reverse-charge procedure are met, we invoice on that basis without VAT. In all other cases, including domestic transactions in Germany, statutory VAT applies according to the tax rules at the place of supply.
  3. Payments are processed through Stripe. The customer authorises us to collect amounts due using the payment method on file.
  4. Where a trial period is offered, it lasts 14 days and requires a payment method. The paid period begins after the trial unless cancelled beforehand.
  5. We provide invoices electronically.

6. Term and termination

  1. The subscription continues for an indefinite period in monthly billing periods.
  2. The customer may terminate at the end of the respective billing period unless otherwise stated during the order process. Termination through the publicly accessible Cancel contracts here button, the customer portal or the Stripe customer area, or in text form, such as by email to contact@steinkauz.ai, is sufficient.
  3. The right to terminate for good cause remains unaffected. Good cause for us includes payment default, serious breach of obligations or abuse.
  4. Access to the paid cloud service ends when the contract ends. Content is subject to the retention and deletion rules described in the Privacy Policy.

7. Withdrawal, expiry of the right and no goodwill refunds

  1. Consumers within the meaning of section 13 BGB have a right of withdrawal as described in the Withdrawal Notice.
  2. Business customers within the meaning of section 14 BGB have no statutory right of withdrawal.
  3. Steinkauz Cloud is a digital service. Starting to use the service or activating the subscription alone does not extinguish the right of withdrawal. Early expiry under section 356(5) BGB requires full performance and the consumer's prior declarations specified there. An ongoing subscription is not fully performed merely by activating access. Statutory rules on compensation for services supplied apply to withdrawal after an expressly requested early start; a free trial remains free.
  4. We do not grant voluntary refunds. Statutory claims, particularly a right of withdrawal that has not yet expired, remain unaffected.
  5. A valid withdrawal ends the contract that is withdrawn from. A refund based on statutory price-reduction or other claims does not automatically end a continuing contract. Suspension due to outstanding payments or payment disputes is permitted only where statutory requirements are met; justified objections remain unaffected.

8. Data processing and confidentiality

  1. The Data Processing Agreement applies to personal customer content. Sub-processors are listed under Sub-processors.
  2. Both parties treat the other party's non-public information as confidential. This does not include information that is publicly known, independently developed or subject to a legal disclosure obligation.

9. Statutory warranty

  1. Statutory warranty rights apply.
  2. Consumer contracts for digital products are subject in particular to statutory rights to conforming provision and necessary updates.
  3. Please inform us of defects so that we can remedy them. Statutory rights do not depend on immediate notification.

10. Liability

  1. We are liable without limitation for intent and gross negligence, injury to life, body or health, under the German Product Liability Act and within the scope of an assumed guarantee.
  2. For slightly negligent breaches of essential contractual obligations, our liability is limited to foreseeable damage typical of the contract.
  3. Liability is otherwise excluded.
  4. These limitations also apply for the benefit of persons performing our contractual obligations on our behalf.
  5. Independent model providers engaged directly by the customer are responsible for their own services. Our liability for our own breaches of duty under the preceding provisions remains unaffected.

11. Changes to these terms

Changes to these terms for existing contracts require agreement with the customer. Silence does not constitute consent. Legally permitted changes to the service under section 3 remain unaffected.

12. Final provisions

  1. The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods.
  2. If the customer is a merchant, a legal entity under public law or a special fund under public law, the place of jurisdiction is Speyer. Statutory places of jurisdiction apply to consumers.
  3. Mandatory consumer protection provisions at the consumer's place of residence remain unaffected.
  4. If a provision is invalid, the remainder of the contract remains effective.
