Terms of service.

Last updated: August 12, 2026

Provider and acceptance

These Terms of Service (the “Terms”) govern your use of HarmonyFlow, including the free AI Chat available at ai-chat.html. The service is provided by Alexander Winter. By accessing or using the AI Chat, you confirm that you have read and accepted these Terms and the Privacy Policy. If you do not agree, do not use the AI Chat.

You must be at least 16 years old to use the AI Chat, unless your use is legally permitted with the consent and supervision of a parent or legal guardian. You are responsible for ensuring that your use is lawful in your country.

The service

HarmonyFlow provides a free, experimental AI chat interface. The service is provided without a user account and without a promise of continuous availability, a particular response time, a particular model, or any particular functionality. I may change, suspend, restrict or discontinue the service, in whole or in part, at any time where legally permitted.

The AI Chat may be unavailable, delayed, rate-limited, interrupted or affected by maintenance, technical failures, capacity limits or changes made by third-party providers. No fee is charged for using the AI Chat.

AI-generated content and user responsibility

AI-generated responses can be inaccurate, incomplete, outdated, biased, misleading, offensive or unsuitable for your circumstances. They may contain made-up facts, sources or code. The AI Chat does not understand your situation and does not provide professional advice.

Do not rely on an AI response as medical, psychological, legal, financial, tax, safety, employment or other professional advice. Always independently verify important information with a qualified professional and test any code before using it. You are solely responsible for your decisions, actions, prompts, the way you use responses and the results of your use of the service.

You must not enter passwords, payment details, special-category personal data, confidential business information or any other information that you are not willing to transmit to the third-party infrastructure described in the Privacy Policy. You are responsible for having the necessary rights and permissions for anything you submit.

Acceptable use

You must not use the service to:

I may block requests, limit access or suspend access without notice if I reasonably believe that these Terms, applicable law, the security of the service or the rights of another person are at risk.

Your content

You retain any rights you have in lawful content that you submit. You grant the limited permission necessary for me and the service providers used by the AI Chat to transmit and process that content to provide, secure and maintain the service. The AI Chat is designed not to store chat history on this website; processing by third-party infrastructure is described in the Privacy Policy.

You represent that your submissions and your use of generated responses do not violate law, these Terms or the rights of others. You are solely responsible for claims arising from content you submit or from your use of the service, subject to mandatory statutory rights.

Third-party services and model licenses

The AI Chat uses a Cloudflare Worker only as the website's server-side proxy. Model inference is provided by two third-party upstreams, each reached through an OpenAI-compatible API:

I do not control AKI.IO, Requesty.ai or other third-party services and am not responsible for their availability, processing, changes or acts and omissions, except where mandatory law provides otherwise.

The chat currently offers the three API-backed models listed above. The applicable models, identifiers, providers and upstream license terms may change. This information does not guarantee that a particular output is original, lawful, accurate or free of third-party rights. If you redistribute model materials rather than merely using this hosted chat, you must comply with the applicable license and provider terms.

Intellectual property

The HarmonyFlow website, its design, text, software and branding are protected by applicable intellectual-property laws. Except for rights expressly granted in these Terms or by law, no rights are transferred. Third-party names, trademarks, software and model materials remain the property of their respective owners.

Disclaimer of warranties

To the maximum extent permitted by applicable law, the website and AI Chat are provided “as is” and “as available”, without warranties of any kind, express or implied, including warranties of availability, accuracy, suitability, non-infringement or fitness for a particular purpose. I do not warrant that the service will be secure, error-free, uninterrupted or suitable for your needs.

Nothing in these Terms excludes or limits a warranty or right that cannot legally be excluded or limited.

Limitation of liability

To the maximum extent permitted by law, I am not liable for indirect, consequential or unforeseeable losses, loss of data, loss of profits, business interruption, reputational damage or damage resulting from reliance on, or use of, an AI-generated response. This includes damage caused by an unavailable service, an incorrect response, a third-party service or content submitted by another user.

For slight negligence, liability is limited to the foreseeable damage typically arising from a breach of material contractual obligations. These limitations do not apply to liability for intent, gross negligence, injury to life, body or health, fraudulent concealment, mandatory product liability or any other liability that cannot be excluded or limited under applicable law. The same applies to liability of legal representatives and persons engaged in performing obligations to the extent required by law.

Indemnification

To the extent legally permissible, you agree to reimburse reasonable claims, losses and necessary costs asserted by third parties against me because you violated these Terms, applicable law or the rights of a third party. This does not apply to the extent that the claim was caused by my own legally relevant fault or where such an obligation cannot be agreed under mandatory law.

Governing law and venue

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not deprive you of mandatory protections granted by the law of the country in which you habitually reside. Statutory consumer rights and statutory places of jurisdiction remain unaffected.

Where legally permissible, the courts at my place of residence have jurisdiction for disputes with businesses, legal entities under public law and special funds under public law. Mandatory jurisdiction rules remain unaffected.

Changes and contact

I may update these Terms when the service, law or third-party requirements change. The version published on this page applies to future use from its stated update date. If a provision is or becomes invalid, the remaining provisions remain effective; the invalid provision is replaced by the legally permissible provision that comes closest to its purpose.
