利用規約

These terms govern your use of kral.ai (the "Service") provided by Martin Král (the "Provider"), a sole trader established in CZ, business ID (IČO) 21106312. kral.ai is a brand operated by Martin Král; it is not a separate legal entity. Full details are on our imprint. By creating an account or using the Service you agree to these terms.

1. Definitions

"Service" means the kral.ai platform and related interfaces and APIs. "User", "you" means the person or entity using the Service. "Consumer" means a User acting outside their trade or profession; "Business customer" means any other User. "Content" means prompts, files, and other material you submit. "Output" means the response generated for you via an AI model. "AI Provider" means a third-party provider of AI models or tools to which the Service routes Content. "Credits" means prepaid units used to access paid features.

2. Eligibility and account

You must be at least 18 years old and have the legal capacity to enter into a contract. You must provide accurate registration information, keep your credentials secure, and are responsible for all activity under your account. Unless we agree otherwise, you may hold one account and may not share or transfer it.

You represent that you are not subject to sanctions and are not located in a country subject to comprehensive sanctions or embargoes. This is required because the Service routes requests to third-party AI providers whose own terms prohibit such use.

3. Service description

The Service is a software-as-a-service gateway that provides access to multiple third-party AI models through a unified interface, with optional API access and a credit- and subscription-based billing model. Available features and supported models may change over time.

4. Acceptable use

You agree not to use the Service to:

• generate content that is illegal, defamatory, or infringes third-party rights;
• circumvent rate limits, billing, or access controls;
• attempt to extract model weights, training data, or operator secrets;
• generate child sexual abuse material or content that sexualises minors;
• create malware, exploits, or content facilitating violence, terrorism, or self-harm;
• impersonate others or create deepfakes intended to deceive, or conduct large-scale disinformation;
• carry out unlawful surveillance or biometric identification;
• make high-risk decisions (medical, legal, financial, employment, or critical-infrastructure) without qualified human oversight;
• use Output to develop a competing AI model or service, or to scrape, mirror, or resell the Service;
• generate content that targets, harasses, or endangers individuals.

You must also comply with the usage policies of the AI Providers whose models you use; those policies apply to your use through the Service. We may use automated and manual means to monitor and enforce acceptable use.

5. Prices, credits and subscriptions

Paid use is based on prepaid credits and/or subscriptions. Prices, rate limits, and feature availability are shown on the pricing page and may change with reasonable notice. Subscriptions are billed in advance for the chosen period and renew automatically until cancelled. Prices are shown including or excluding VAT as applicable to your country and customer type. For business customers in other EU countries with a valid VAT ID, the reverse-charge procedure applies.

Credits and subscriptions are prepaid and are consumed as you use the Service. A purchase grants access to the Service on a best-effort basis only and is not a binding guarantee that any particular model, feature, capacity, throughput, or price level will remain available; we may change, limit, suspend, or discontinue any part of the Service, including individual models or features, at any time. To the extent permitted by law, prepaid amounts and subscription fees are non-refundable, credits already consumed are in no case refundable, and you waive any claim to reimbursement, set-off, or chargeback beyond your mandatory statutory rights. By purchasing credits or a subscription you expressly agree to this. Your mandatory consumer rights under section 6 remain unaffected.

Any prices, per-request costs, token rates, or usage figures shown in the Service (for example in the usage or cost overview) are indicative only. They are based on third-party provider pricing and measured usage, and may change at any time and be corrected retroactively to reflect actual upstream costs or measurement errors. They do not constitute a binding price quote; the amount actually charged or deducted from your credit balance is authoritative.

You authorise the Provider and its payment processor to charge your chosen payment method for all fees, including recurring subscription fees, until cancelled. If a payment fails, we may retry it, suspend access, and the amount remains due. A chargeback or payment reversal that is not legally justified is a breach of these terms; we may suspend your account, and the disputed amount plus any costs becomes immediately due.

Vouchers, promotional codes, gift codes, and discounts are issued at our discretion, are non-transferable, have no cash value, cannot be exchanged for money, and may be limited, suspended, modified, revoked, or invalidated at any time without notice. You have no entitlement to any voucher or promotional code, to redeem one, or to its continued validity.

6. Right of withdrawal (consumers)

If you are a consumer in the EU, you generally have a 14-day right of withdrawal. Credits and paid digital features are digital content that we supply to your account immediately. By completing your purchase you expressly request that supply begins immediately and acknowledge that you thereby lose your right of withdrawal as soon as supply begins (§ 1837 of the Czech Civil Code, implementing the EU Consumer Rights Directive). A completed purchase is therefore non-refundable, except where mandatory law provides otherwise. Business customers (B2B) waive consumer-style withdrawal rights to the extent permitted by law.

7. Third-party AI providers and data transmission

By using the Service, you instruct and consent to your Content being transmitted to and processed by the AI Providers you select within the Service, which may be located anywhere in the world, including outside the EU/EEA. The AI and tool providers we use are listed in our privacy policy. You are responsible for ensuring you are entitled to submit that Content for such processing and that it does not contain data you are not permitted to share.

8. Your content and our access to it

You retain ownership of the Content you submit. You grant the Provider a worldwide, non-exclusive licence to process that Content as necessary to provide the Service (for example by forwarding prompts to the AI Provider you select).

You further grant the Provider the right to access, store, process, and analyse your Content (including prompts, Output, uploaded files, and associated metadata) as necessary to operate, maintain, secure, debug, support, and improve the Service, to prevent abuse and fraud, to perform billing, and to comply with legal obligations. The Provider does not use customer Content to train its own models.

9. Output

Output is generated via third-party AI models and may be inaccurate, incomplete, biased, or otherwise inappropriate. Output is not professional advice (legal, medical, financial, or otherwise), and you must independently verify it before relying on it. As between you and the Provider, and subject to the applicable AI Provider's terms, you may use the Output you generate; however, Output is not guaranteed to be unique, and similar or identical Output may be generated for other users. You are responsible for ensuring your use of Output does not infringe third-party rights or violate law. The Provider does not guarantee the accuracy, completeness, or fitness for any purpose of Output, nor any rights in it beyond those granted by the applicable AI Provider.

10. Suspension, termination and forfeiture

We may suspend or terminate your account, and restrict or remove access to Content or Credits, immediately and without notice where we reasonably believe you have materially breached these terms, used the Service unlawfully, or created risk or legal exposure for the Provider or the AI Providers. In the case of a serious or repeated breach, any remaining Credits may be forfeited without refund, to the extent permitted by law.

11. Beta and experimental features

Features marked as beta, preview, or experimental are provided for evaluation only, without warranty, and may be changed or withdrawn at any time. They may be subject to additional terms.

12. Availability and force majeure

The Service is provided on an "as is" and "as available" basis. We aim for high uptime but do not guarantee uninterrupted operation. The Provider is not liable for any failure or delay caused by events beyond its reasonable control, including internet or hosting outages, acts or omissions of AI Providers (including model deprecations, rate limiting, or discontinuation of their services), power failures, strikes, or force-majeure events. No such event gives rise to a refund or damages claim beyond your mandatory statutory rights.

13. Liability and indemnity

To the extent permitted by law, the Provider is liable without limitation only for damage caused intentionally or by gross negligence, and for injury to life, body, or health. For slight negligence the Provider is liable only for breach of an essential contractual obligation, limited to the foreseeable, typical damage. Liability for indirect damages, lost profits, loss of data, or damage arising from Output is excluded to the extent permitted by law. Mandatory statutory liability remains unaffected.

To the extent permitted by law, you agree to indemnify and hold the Provider harmless from third-party claims arising out of your use of the Service or the Content you submit. You use the Service, and rely on its Output, at your own risk.

14. Intellectual property

The Service, including its software, design, trademarks, and documentation, is and remains the property of the Provider and its licensors. These terms grant you no rights in the Provider's intellectual property other than the limited right to use the Service. If you provide feedback or suggestions, you grant the Provider a perpetual, irrevocable, royalty-free licence to use them without restriction.

15. Term and termination

You may close your account at any time from the dashboard. We may terminate accounts that violate these terms, with or without notice depending on the severity. Provisions on payment, liability, indemnity, intellectual property, confidentiality, and governing law survive termination.

16. Changes to these terms

We may revise these terms as the Service evolves. Material changes will be announced before they take effect; continued use after the change indicates acceptance.

17. Consumer dispute resolution

If you are a consumer, the body competent for the out-of-court settlement of consumer disputes is the Czech Trade Inspection Authority (Česká obchodní inspekce), www.coi.cz. The European Commission also provides an online dispute-resolution platform at ec.europa.eu/consumers/odr. Your mandatory rights remain unaffected.

18. General

Severability. If any provision of these terms is held invalid or unenforceable, it shall be modified to the minimum extent necessary or severed, and the remaining provisions remain in full force. No waiver. Our failure to enforce a provision is not a waiver of it. Assignment. You may not assign these terms without our consent; we may assign them, including to a successor in connection with a merger, acquisition, or sale of assets. Entire agreement. These terms, together with the privacy policy and any terms shown on the pricing or checkout pages, form the entire agreement between us. Notices. You agree that we may communicate with you electronically; notices to you are deemed received when sent to your account email. Contact. By providing your email address or phone number, you consent to the Provider using them to contact you about the Service, related products, offers, and to collect feedback, including by telephone call, SMS, and email. You may withdraw this consent at any time with effect for the future via [email protected] or in your account settings; withdrawal does not affect the lawfulness of contact made beforehand.

19. Governing law and language

These terms are governed by the laws of the Czech Republic, excluding its conflict-of-laws rules and without prejudice to mandatory consumer-protection rights of your country of residence. The place of jurisdiction is the Provider's seat, to the extent legally permissible. These terms are available in Czech, English, and German; in case of discrepancy, the Czech version prevails.
