Amfion Terms of Service

Effective date: November 11, 2026 · Last updated: November 11, 2026

These Terms of Service (“Terms”) are a binding agreement between you and Viacheslav Sergeev, doing business as Amfion (“Amfion,” “we,” “us”), governing your use of amfion.co, app.amfion.co, our software, documents, outputs and related services (the “Service”). By using the Service, creating an account, or clicking “agree,” you accept these Terms and our Privacy Policy. If you do not agree, do not use the Service.

PLEASE READ SECTIONS 6 TO 9 CAREFULLY. THE SERVICE PRODUCES AI-GENERATED DRAFTS AND ESTIMATES THAT MAY BE WRONG. THEY ARE NOT PROFESSIONAL ADVICE. OUR LIABILITY IS LIMITED, AND DISPUTES ARE RESOLVED BY BINDING ARBITRATION WITH A CLASS-ACTION WAIVER.

1. Eligibility and accounts

The Service is offered only to users located in the United States. We do not offer, market or direct the Service to residents of the European Union, European Economic Area, United Kingdom or Switzerland, and you may not use it from or on behalf of anyone there; if you do, you do so at your own risk and acknowledge that we do not act as a provider to you under those jurisdictions’ laws. You must be at least 18 and able to form a binding contract. If you use the Service for a company, you represent that you have authority to bind it, and “you” includes it. You are responsible for your account, for keeping your email account secure, and for everything done under your account. Tell us immediately at slava@amfion.co if you suspect unauthorized use. We may refuse, suspend or close accounts at our discretion.

2. The Service

Amfion helps you draft, price, review and export scopes of work and related documents for residential renovation projects, using artificial intelligence and third-party data. We may add, change, limit or remove features, impose usage limits, or stop the Service, in whole or in part, at any time, with or without notice. The Service may be in beta or early release; it may contain errors and be unavailable at times.

3. Fees

The Service may be free, paid, or partly each. If you buy a paid plan, you agree to the price, billing period and terms shown at purchase, which become part of these Terms. Fees are non-refundable except where the law or our stated refund policy says otherwise. We may change prices with notice; continued use after the change means you accept it. Taxes are your responsibility unless we say otherwise.

4. Your content

“Your Content” is everything you submit: text, addresses, budgets, messages, photos, files, bids, reports and documents, plus the documents you build in the Service.

You own Your Content. You grant us a worldwide, non-exclusive, royalty-free, sublicensable license to host, store, copy, process, transmit, modify, analyze, create derivative works from, display and otherwise use Your Content to provide, secure, support, analyze, improve and develop the Service and our models, products and datasets, including after you delete it or close your account, to the extent it has been incorporated into aggregated, de-identified or model-improvement data or backups. We and people working for us may view Your Content, including the files you attach, to provide support, investigate problems, check the quality of Outputs, and improve the Service. You may ask us not to use Your Content for model improvement as described in the Privacy Policy.

You represent that you have all rights needed to submit Your Content and grant this license; that it does not violate any law or third-party right (including privacy, copyright, confidentiality and the terms of contractors or inspectors whose documents you upload); and that it does not contain malware or illegal material.

We may remove or refuse any content, and we may disclose it as described in the Privacy Policy.

5. Outputs

“Outputs” are the drafts, estimates, prices, summaries, classifications, suggestions, reviews, PDFs and other material the Service generates for you. Subject to these Terms, we assign to you whatever rights we hold in Outputs generated for your account; you may use them for any lawful purpose. Outputs may be similar or identical to Outputs generated for other users, and we make no claim of uniqueness.

6. AI disclaimer: not professional advice

The Service uses machine-learning models and third-party data that are probabilistic and imperfect. Outputs may be inaccurate, incomplete, outdated, inconsistent, or wrong, including prices, quantities, code requirements, permit needs, measurements, timelines, and the reading of documents and photos you provide.

Outputs are not construction, engineering, architectural, legal, financial, lending, appraisal, tax, insurance, real-estate or any other professional advice, and no professional-client relationship is created. Cost estimates are generalized references, not quotes or bids, and actual costs vary by location, time, materials, contractor, site conditions and scope. You must independently verify every Output before relying on it, obtain your own contractor bids, inspections, permits and professional advice, and comply with all applicable laws, codes and lender requirements. You are solely responsible for every decision, purchase, bid, loan, contract and construction activity you undertake, and for any document you present to a lender, buyer, contractor, insurer or authority.

7. Acceptable use

You will not: use the Service unlawfully or for anyone under 18; upload content you have no right to use, or that is defamatory, infringing, harassing, obscene or harmful; reverse engineer, scrape, crawl, or extract data, prompts, models or source code; access the Service by automated means other than our published interfaces; probe, overload, or interfere with the Service or its security; circumvent limits, fees or access controls; use the Service to build a competing product or to train models; misrepresent Outputs as professionally certified or as having been reviewed by a licensed professional; or let others use your account. We may monitor use and enforce these rules by any means, including suspension and legal action.

8. Intellectual property and feedback

The Service, including its software, models, prompts, designs, text, pricing data, trademarks and all related rights, belongs to us or our licensors and is protected by law. You receive only a limited, revocable, non-exclusive, non-transferable license to use the Service as permitted here. Any feedback, ideas or suggestions you give us may be used freely without obligation to you.

If you believe content on the Service infringes your copyright, send a notice identifying the work, the infringing material, your contact details and a good-faith statement (for US works, compliant with 17 U.S.C. § 512(c)(3)) to slava@amfion.co.

9. Disclaimers, limitation of liability, indemnity

DISCLAIMER. THE SERVICE, OUTPUTS AND ALL CONTENT ARE PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AVAILABILITY, OR THAT DEFECTS WILL BE CORRECTED. WE DO NOT WARRANT THAT ANY OUTPUT IS CORRECT, COMPLETE, OR SUITABLE FOR ANY PURPOSE.

LIMITATION OF LIABILITY. TO THE FULLEST EXTENT PERMITTED BY LAW, AMFION, ITS OWNER, OFFICERS, EMPLOYEES, CONTRACTORS, AFFILIATES, LICENSORS AND PROVIDERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, SAVINGS, DATA, GOODWILL, PROPERTY VALUE, CONSTRUCTION COSTS, FINANCING, OR BUSINESS OPPORTUNITY, ARISING FROM OR RELATED TO THE SERVICE OR OUTPUTS, HOWEVER CAUSED AND UNDER ANY THEORY, EVEN IF ADVISED OF THE POSSIBILITY. OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING FROM OR RELATED TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM AND (B) ONE HUNDRED US DOLLARS ($100). SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS; IN THOSE, OUR LIABILITY IS LIMITED TO THE MAXIMUM EXTENT PERMITTED.

INDEMNITY. You will defend, indemnify and hold harmless Amfion and the persons listed above from any claims, damages, losses, liabilities, costs and expenses (including reasonable attorneys’ fees) arising from Your Content, your use of the Service or Outputs, your projects, your violation of these Terms or of any law, or your violation of any third party’s rights.

10. Termination

You may stop using the Service and ask us to delete your account at any time. We may suspend or terminate your access at any time for any reason, including inactivity or breach, with or without notice. On termination your license ends; sections that by nature should survive (including 4 through 9 and 11 through 13) survive.

11. Dispute resolution: arbitration and class waiver

Informal resolution first. Before filing a claim, you agree to email slava@amfion.co describing the dispute and to try in good faith to resolve it for 60 days.

Binding arbitration. Any dispute, claim or controversy arising from or relating to these Terms or the Service that is not resolved informally will be settled by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules (or, if the AAA will not administer the dispute, by JAMS or another reputable arbitration body we designate), except that either party may bring an individual claim in small-claims court or seek injunctive relief for intellectual-property misuse in court. The Federal Arbitration Act governs this section. Arbitration will be conducted by video conference or written submissions unless the arbitrator decides an in-person hearing is necessary, and the arbitrator may award the same relief a court could, on an individual basis only.

Class-action and jury waiver. YOU AND AMFION WAIVE ANY RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS, COLLECTIVE, CONSOLIDATED OR REPRESENTATIVE ACTION. If this waiver is found unenforceable for a claim, that claim must proceed in court, and the rest of this section still applies.

Opt-out. You may opt out of arbitration by emailing us within 30 days of first accepting these Terms, stating your name, account email and intent to opt out.

12. Governing law and venue

These Terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-law rules, except where the mandatory consumer-protection law of your country of residence applies to you. For anything not subject to arbitration, you consent to the exclusive jurisdiction of the state and federal courts located in Delaware, and we may also seek relief in the courts of your country of residence.

13. General

These Terms, with the Privacy Policy and any order terms, are the entire agreement between you and us about the Service and supersede prior agreements. We may update these Terms; we will post the new version with a new date and, for material changes, notify you by email or in the Service. Continued use after the change means you accept it. If any provision is unenforceable it will be limited to the minimum extent necessary and the rest remains in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms; we may assign them freely. We are not liable for delays or failures caused by events outside our reasonable control. Notices to you may be sent to your account email. Notices to us go to slava@amfion.co. Nothing here creates a partnership, agency or employment relationship. You will comply with applicable export-control and sanctions laws, including those of the United States.
