Terms of Service

PLEASE READ SECTION 15 CAREFULLY. IF YOU LIVE IN THE UNITED STATES, IT REQUIRES YOU AND US TO RESOLVE MOST DISPUTES BY BINDING INDIVIDUAL ARBITRATION INSTEAD OF IN COURT, AND IT WAIVES CLASS ACTIONS AND JURY TRIALS. YOU MAY OPT OUT WITHIN 30 DAYS.

These Terms are a contract between you and Kenta Yamamoto, a sole proprietor in Japan ("we" or "us"), who operates Exact 3D Video at exact3dvideo.com (the "Service"). You accept these Terms when you confirm your agreement on the screen shown when you first sign in, or when you buy credits. If you do not agree, do not use the Service.

Our Pricing and Credits page and Legal Notice are part of these Terms. Our Privacy Policy explains how we handle your information.

1. Who may use the Service

  1. You must be at least 18 years old. You may not use the Service for, or as part of, anything directed at people under 18.
  2. The Service is not offered to users in the European Economic Area, the United Kingdom, or Switzerland, and you may not use it from those places.
  3. You may not use the Service if you are on a government list of restricted parties, or from a country or region under a US or Japanese embargo. You must follow the export control and sanctions laws that apply to you and your materials.
  4. If you use the Service for a company or other organization, you confirm that you have authority to accept these Terms for it, and "you" includes that organization.
  5. We operate the Service from Japan and wrote these Terms mainly for users in the United States. If you use it from another country, you are responsible for following your local laws, and you keep any consumer rights that your local law does not allow you to give up.

2. The Service and its use of AI

  1. You chat with an AI, not a person, and you can attach documents or CAD files. The AI writes a storyboard, builds 3D computer graphics in 3D rendering software on GPUs, adds AI narration and captions, and delivers an MP4 video.
  2. We use AI from Anthropic (Claude) for chat and building, and AI from Google (Gemini) for narration. Narration is a synthetic AI voice, not a human recording, and it contains Google's SynthID digital watermark.
  3. AI output can be wrong or incomplete. You are responsible for checking every fact, number, dimension, and claim before you use a video. Videos are for explanation and communication. They are not engineering, medical, legal, or financial advice.
  4. We may add, change, or remove features and AI models.

3. Your account and support

  1. You sign in through a third-party login service. Keep that login secure and do not share your account. You are responsible for what happens under your account.
  2. We do not store your email address or name, so we identify accounts by Account ID and chats by Chat ID. To get support, use Contact Support at the bottom of the chat screen or on the Account page. We reply in the app. If you cannot sign in, email service@3dcgdouga.com with any IDs you have.
  3. When needed to find the cause of a defect, we may check your conversation and the AI's work records, as described in the Privacy Policy.

4. Your materials

  1. You keep your rights in the documents, CAD files, images, and text you provide ("Materials").
  2. You promise that you have all rights and permissions needed for your Materials, and that using them in the Service is lawful, including sending them to AI vendors in other countries.
  3. Include personal information only when it is needed, and only after doing what the law requires, such as getting consent. Do not include sensitive information, such as health records, financial account numbers, or government ID numbers, unless the video truly needs it and you are allowed to use it.
  4. You allow us and our service providers to store, copy, convert, and process your Materials and outputs as needed to provide the Service, calculate charges, investigate problems, enforce these Terms, and comply with the law.

5. Prohibited uses

You may not use the Service to:

You are responsible for how you publish and use your videos, including any disclosure the law requires. For example, some states require an advertisement to disclose a synthetic performer, which can include an AI voice, and some states restrict AI-generated content about elections.

If we reasonably believe you have broken these rules or the law, we may, without prior notice, block or delete output, stop a share link, or suspend or close your account. Credits are not refunded in that case, except as required by applicable law.

6. Your videos

  1. Any rights we hold in a video you make transfer to you once the charges for that video are paid. You may use your videos, including commercially, subject to these Terms and the law.
  2. We do not promise that a video or any part of it is protected by copyright. US law generally protects only human authorship, so material made purely by AI may not be protected.
  3. Fonts and other third-party materials in a video stay under their own licenses, such as the SIL Open Font License.
  4. Because of how AI works, other users may receive similar output.
  5. We keep all rights in the Service, its software, and our name and logos.

7. Credits and payment

  1. Charges are based on usage: AI processing, GPU rendering, storage, and data transfer, as described on the Pricing and Credits page. You pay from prepaid credits. One credit equals US$0.01, and prices are in US dollars.
  2. Before each run we show an estimate and an upper limit. The final charge is based on actual usage. Credits up to the upper limit are reserved while a run is in progress and cannot be used for anything else until it ends.
  3. We do not charge for processing that fails because of our defect or that stops at the time limit. If the AI refuses a run because of its content, we charge for usage up to that point.
  4. If a final charge is more than your balance, the shortfall is deducted from your next purchase, and new runs and video links may be unavailable until it is cleared.
  5. Purchased credits do not expire. If your balance also includes free credits or credits bought on our Japanese site, the ones that expire soonest are used first. You can add credits to your balance at any time.
  6. Credits can be used only in the Service, with your own account. You may not sell, transfer, or give them to anyone. They are not legal tender, a deposit, or a gift card, and we do not sell them as gifts.
  7. PURCHASED CREDITS ARE NOT REFUNDABLE, INCLUDING UNUSED OR LEFTOVER CREDITS, EXCEPT AS REQUIRED BY APPLICABLE LAW. If you close your account, your remaining credits end and are not refunded, except as required by applicable law.
  8. If a gift-certificate law or other law that applies to you gives you more, such as a right to redeem a small balance in cash, we will follow that law. Contact us with your Account ID.
  9. Prices do not include taxes. Taxes may apply, and we may add them where required.
  10. Stripe processes payments. We do not receive or hold your card number. Because the seller is in Japan, your bank may charge foreign transaction or currency conversion fees.
  11. If a payment is refunded, reversed, or disputed, we may remove the related credits. If they have been used, the amount is treated as a shortfall under paragraph 4. This does not limit your rights under the law or your card issuer's rules.
  12. We may change usage rates and prices. The estimate shown before a run reflects the rates in effect at that time.

8. Storage and keeping videos

  1. Attachments and outputs, including videos, review images, and production data, are automatically deleted 30 days after they are saved. Download anything you need before then.
  2. You can pay in advance to keep a finished video until a date you choose, and you can extend that date before it passes. Keeping covers the video file and its thumbnail only. Production data and attachments are still deleted after 30 days. Kept videos are automatically deleted when the period ends.
  3. Keep fees are not refunded if you delete the video or close your account early, except as required by applicable law.
  4. Keep your own copies. We do not promise to preserve or recover anything beyond what this Section describes.

9. Free credits, referrals, and share links

  1. We may give free credits for signing up, referrals, or promotions. Free credits are promotional, expire on the date shown when you receive them, have no cash value, and cannot be refunded, exchanged for cash, or transferred, except as required by applicable law. Sign-up credits are limited to one per person.
  2. You may invite people you know with an invite link. If we offer a referral reward, we show the amount and conditions in the Service and grant it to both of you when the person you referred first buys credits. We may withhold or cancel a reward for self-referrals, false information, or other abuse. If you recommend the Service and can receive a reward, say so clearly wherever you recommend it.
  3. You can create a share link for a finished video. Anyone with the link can watch the video without signing in. You are responsible for making sure a shared video does not infringe anyone's rights or reveal confidential information. The share page states that the video was made with the Service and links to the Service. You can stop sharing at any time, and the link stops working when the video is deleted. We may stop a share link if we believe it may break the law or these Terms.

10. Reporting infringing or harmful content

We respond to copyright notices under the Digital Millennium Copyright Act and, in appropriate circumstances, terminate the accounts of repeat infringers. We also accept reports of intimate images published without consent. The Legal Notice explains how to send either one.

11. DISCLAIMER OF WARRANTIES

EXCEPT AS REQUIRED BY LAW, THE SERVICE, CREDITS, AND ALL OUTPUT ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITH ALL FAULTS. WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT PROMISE THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE, THAT OUTPUT WILL BE ACCURATE, OR THAT A RUN WILL PRODUCE THE RESULT YOU WANT.

12. LIMITATION OF LIABILITY

TO THE FULLEST EXTENT THE LAW ALLOWS: (A) WE ARE NOT LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, OR GOODWILL; AND (B) OUR TOTAL LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE, INCLUDING SERVICE INTERRUPTIONS, DEFECTS, AND AI OUTPUT, IS LIMITED TO THE GREATER OF THE AMOUNT YOU PAID US FOR THE SERVICE IN THE 12 MONTHS BEFORE THE DAMAGE OCCURRED OR US$100.

THESE LIMITS DO NOT APPLY TO OUR FRAUD, GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT, OR TO ANY OTHER LIABILITY THAT THE LAW DOES NOT ALLOW US TO LIMIT.

13. Responsibility for business use

If you use the Service for a business or other commercial purpose, you will defend and compensate us against third-party claims, including reasonable attorney's fees, that arise from your Materials, your videos, or your breach of these Terms, to the extent the law allows.

14. Ending the Service and changing these Terms

  1. You may stop using the Service at any time and close your account from the Account page. Closing your account deletes your data as described in the Privacy Policy.
  2. We may suspend or close your account if you break these Terms, if the law requires it, or to protect the Service or other people.
  3. We may change or discontinue the Service. We will try to give reasonable advance notice in the Service before discontinuing it, so you can use your credits and download your videos.
  4. We may change these Terms. We will post the new version and tell you in the Service, and for a material change we will ask you to accept it when you next sign in. Changes apply going forward, not to disputes that arose before they took effect. If you do not accept a change, stop using the Service.
  5. Terms that by their nature should continue, including Sections 6, 7, 11, 12, 13, 15, 16, and 17, continue after your account ends.

15. BINDING ARBITRATION AND CLASS ACTION WAIVER

This Section applies if you live in the United States.

  1. Try us first. Before starting a proceeding, send a description of the dispute, what you want, and your Account ID to service@3dcgdouga.com. We will try to resolve it within 30 days. Any deadline for your claim is paused during those 30 days.
  2. Arbitration. Any dispute that is not resolved this way and that arises out of or relates to these Terms or the Service will be decided by binding individual arbitration, not in court. The Federal Arbitration Act governs this Section. The American Arbitration Association (AAA, www.adr.org) will administer the arbitration under its rules in effect at the time, using its Consumer Arbitration Rules and its mass arbitration rules where they apply. If the AAA cannot or will not administer it, you and we will choose another neutral provider, or a court will appoint an arbitrator.
  3. Small claims and agencies. Either of us may instead bring an individual claim in small claims court if it qualifies and stays there. For a small claims case against us, you may serve the claim by email to service@3dcgdouga.com and by mail to the address in the Legal Notice. Nothing here stops you from reporting a concern to a government agency.
  4. How it works. One arbitrator decides. Hearings will be by video, by phone, or on written submissions unless the arbitrator decides otherwise, and any in-person hearing will be in the county where you live unless we agree otherwise. The arbitrator may award the same individual relief a court could award. The arbitrator decides all disputes, except that only a court may decide whether paragraph 6 or 7 is enforceable.
  5. Fees. You pay no more than the lesser of the AAA's consumer filing fee and the filing fee of the court in the county where you live. We pay all other AAA fees and the arbitrator's compensation, unless the arbitrator finds that your claim was frivolous or brought to harass. We will not seek attorney's fees from you unless the arbitrator makes that finding. If the law gives you a right to attorney's fees, the arbitrator can award them.
  6. CLASS ACTION AND JURY TRIAL WAIVER. YOU AND WE MAY BRING CLAIMS ONLY ON AN INDIVIDUAL BASIS. NEITHER OF US MAY BRING OR TAKE PART IN A CLASS, COLLECTIVE, OR REPRESENTATIVE ACTION, AND NO ARBITRATOR MAY TURN INDIVIDUAL CLAIMS INTO A CLASS PROCEEDING. YOU AND WE GIVE UP THE RIGHT TO A JURY TRIAL.
  7. Public injunctive relief. If the law lets you seek an injunction for the benefit of the public and does not let you waive that right, the request goes to a court after the arbitration of your individual claims finishes, and the court case is on hold until then.
  8. Opting out. You may opt out of this Section by emailing service@3dcgdouga.com within 30 days after you first accept these Terms, with the subject "Arbitration opt-out" and your Account ID. Opting out does not affect the rest of these Terms or your access to the Service. If we make a material change to this Section, you may opt out of that change the same way within 30 days after we notify you.
  9. If part of this Section cannot be enforced. That part is removed and the rest stays in force. If paragraph 6 cannot be enforced for a claim, that claim, and only that claim, goes to court and does not proceed as a class arbitration.

16. Governing law and courts

These Terms and any dispute relating to them or the Service are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-law rules, except that the Federal Arbitration Act governs Section 15. This choice does not remove any protection that the consumer law of the place where you live gives you and that cannot be waived by contract. The UN Convention on Contracts for the International Sale of Goods does not apply.

A dispute that is not arbitrated will be decided by the state or federal courts located in Delaware, and you and we consent to their jurisdiction. If the law of the place where you live gives you the right to sue in a court there, you keep that right.

17. General

Effective date: November 7, 2026
