1. The agreement and what the service covers

These terms govern access to the DouTok AI website, the PWA and related features. Before first using a protected account, syncing or the chat, you actively confirm the current version of the Terms and the privacy notice. If you do not accept them the protected service is not provided; the public information pages stay available. If you are acting for an organisation, you confirm that you are entitled to bind it.

DouTok AI provides conversational AI, conversation management, syncing between authorised devices, work with supported attachments, and public data features. Features can differ by plan, platform, provider availability and region.

2. Account, devices and security

You are responsible for the accuracy of your account details, for protecting your session, and for controlling connected devices. Paired devices and apps use a separate revocable token issued after approval in the web interface; no provider AI or storage keys are ever sent to the browser. You can revoke a device in the account settings. You must tell DouTok about suspected misuse without undue delay.

3. AI output, availability and the open-source layer

DouTokAI‑0.1 is a product layer over the available open-weight routes and fallbacks. AI output can be incomplete, inaccurate, biased or unsuitable for a particular purpose. It is not legal, medical, financial, safety or any other professional advice. You verify material claims and carry responsibility for the human decision and for how the output is used.

The service aims for resilient fallbacks, but makes no absolute promise of uninterrupted availability, of a particular model, of speed, of accuracy, or of keeping any one feature. Maintenance, abuse protection, a network fault or an unavailable external source can limit the service.

4. Your content and the licence the service needs

“User content” covers prompts, chats, images, video, documents and other data you upload or create. You keep the rights to your own content, subject to the rights of third parties.

You grant DouTok a non-exclusive, worldwide, royalty-free licence, transferable only to the processors it needs, and limited to hosting, storing, backing up, transmitting, technically formatting, displaying and processing the content only as far as is necessary to provide, secure, support and keep the service reliable. The licence ends when the content is deleted, apart from technically necessary backups for the period stated in the privacy notice and cases required by law.

DouTok will not use your content to train or improve a model beyond running the service without your separate, voluntary opt-in, which you can withdraw at any time. Withdrawal takes effect going forward and does not undo processing already lawfully completed or irreversibly aggregated.

5. Prohibited use

You must not use the service to infringe rights, to upload content you do not have the necessary permissions for, to circumvent security measures, to distribute malware, to commit fraud, for discriminatory or unlawful conduct, for spam, to intrude on privacy, to generate illegal content, or to scrape data against a source's terms. You must not present AI output as verified professional advice when it does not have that status.

6. Human review of chats, and moderation

Chats, prompts, AI answers and other content you send through DouTok AI are not only processed by machines — people can see them too. Authorised people acting for DouTok, including the operator and owner of the service personally and staff or contractors bound to confidentiality, may view, read, annotate and assess conversations in order to run and support the service, investigate abuse and security incidents, enforce these terms, improve the quality and safety of the service, and comply with the law.

So do not enter anything into the chat that you do not want a person to see: passwords, payment card details, health data, trade secrets, or other confidential or sensitive information about yourself or anyone else. Where possible, content is reviewed without the account's identifying details, access is limited to the people who need it, and access is recorded.

DouTok may use automated and human checks. On reasonable suspicion of a breach of these terms, a threat to the service, or a legal obligation, DouTok may restrict or remove content, suspend or close an account, or provide information to the competent authorities.

7. Keeping chats, and their use in legal proceedings

DouTok may keep, disclose and use chats, account data and records of use where that is necessary to comply with a legal obligation, a court decision or a lawful request from a public authority; to establish, exercise or defend legal claims; or to protect the rights, safety and property of DouTok, its users or third parties. This includes using them as evidence in court, arbitration, administrative, criminal and other proceedings, and handing them to courts, law enforcement authorities, lawyers and other parties to those proceedings, as far as the law allows.

In such a case chats may be kept for longer than the usual period stated in the privacy notice, until the matter is closed. Deleting a chat or an account does not prevent this where the content has to be kept by law or has been secured for a pending matter.

8. AI model providers and their terms

Answers in DouTok AI are generated by models from third-party providers — for example Google (Gemini, Gemma), NVIDIA, Groq, Cerebras, OpenRouter, Hugging Face, Together AI, DeepInfra, Fireworks AI, SiliconFlow, Mistral, Cohere, Cloudflare, GitHub Models, Vercel AI Gateway — and, through those gateways, possibly by models developed by OpenAI, Anthropic, Meta and others. Your prompts and the context they need are passed to the provider that answers them, which processes them under its own terms and privacy rules.

By using DouTok AI you also agree to follow the terms of use and acceptable use policies of the providers and models that answer you, as far as they apply to that use; they are linked at the end of this document. Where a provider's rules are stricter than these terms, the stricter rule applies, and a breach of a provider's rules is also a breach of these terms. If you connect your own API key, that use is governed directly by your contract with that provider, and you are responsible for complying with it.

Some providers state in their own terms that people may review inputs and outputs, and that content sent through free or trial services may be used to improve their products — Google's Gemini API terms, for example, say so for unpaid services. DouTok chooses providers and settings to limit this where it can, but cannot change a provider's own practices.

9. Plans, business use and payments

Free and paid features are described in the interface. The credits you see are a product unit; the current conversion and the limits are on the Pricing page. A one-off token pack does not change a subscription, and completing the return page alone does not create a claim to a balance — crediting requires a verified payment confirmation and a server-side record.

A business user provides their own lawful basis for the data of their employees, customers and collaborators. Where paid plans are agreed, price, currency, renewal, taxes, cancellation and refunds follow the details given at the time of the order and the payment provider's own terms.

10. Intellectual property

The software, brand, design, documentation and other elements of the service belong to DouTok or its providers. Unless expressly stated otherwise, these terms grant no right to copy, sell, reverse-engineer or build derivative products from the service. AI output can be subject to third-party rights; DouTok does not guarantee that it is original, non-infringing, or suitable for registering protection.

Copyright of the games. The games in DouTok AI — including Red Mesa, MHD Simulator, Speed Roads, Průsmyky, the arcade games and the shooter — their code, worlds, maps, missions, stories, characters, text, music, sound design and the way all of it is put together are © DouTok corporation. All rights reserved. You may play them for yourself. You must not copy, reproduce, clone, re-create, re-host, mirror, redistribute, sell, sublicense or publish any of the games or any substantial part of one (including its code, maps, stories, or its look and feel), whole or in part, in any medium; you must not extract, scrape or decompile its assets; and you must not present a copy or a close imitation as your own or as a product of DouTok. A breach of this section can lead to suspension of your account and to legal action, including claims for damages and for removal of the copy.

Third-party materials. Some models, sounds and fonts used in the games come from open sources under their own licences (for example CC0 or Apache-2.0). They are credited in the games and in the credits files that ship with them. Those licences stay with the original authors and apply to the individual files as the authors published them; they give nobody the right to copy the games that are built from them.

Music and radio. The music made for DouTok — the DouTok Songs station and the songs “The Iron Mile” and “The Last Stand at Copper Mesa” — and every other game, app, story, character, picture, sound, name and logo of DouTok belongs to DouTok. You may listen to the music and play the games inside the app only. You must not record, rip, download, re-upload, remix, sell, rent or use any of it in your own videos, streams, games or products, and you must not scrape or bulk-collect it or use it to train, fine-tune or test any AI or music model.

Third-party streams. Radio stations, TV channels and live cameras shown in the app are streamed directly from their broadcasters or platforms through public lists; DouTok does not host, record or control them and holds no rights to them. Their content belongs to its owners and their own terms apply to you. If you are a rights holder and want a station, channel or camera removed, write to doutok@icloud.com and it will be taken off promptly.

11. Liability

To the fullest extent applicable law allows, the service is provided “as is” and “as available”. DouTok is not liable for indirect, consequential, special or punitive damages, lost profit, lost data or lost business opportunity arising from using or being unable to use the service. Where DouTok's liability to a business user may validly be limited, the total limit will not exceed the amount that user actually paid for the service in the twelve months before the claim arose, or EUR 100, whichever is higher.

This clause does not limit liability that cannot be limited or excluded under applicable law, in particular mandatory consumer rights and harm caused intentionally or by gross negligence where such a limit is not permitted.

12. Governing law and disputes

For users in Czechia and the EU, Czech law and directly applicable EU law apply, without prejudice to the mandatory provisions of the country where a consumer habitually resides. Jurisdiction is determined by the binding consumer-protection rules. For business relationships the courts of the Czech Republic have jurisdiction. Users outside the EU may be subject to further mandatory rules of their own country.

13. Changes and contact

DouTok may change these terms for reasonable grounds, for example a change to a feature, to the law or to security. For material changes it will give reasonable advance notice of the effective date. Send questions, suggestions and notices to doutok.support@icloud.com.
