Terms & Conditions

Who We Are and What You Are Agreeing To

Fukurō is operated by CINELLI E TRINDADE TECNOLOGIA LTDA (trading as "HalTuring"), CNPJ 46.909.927/0001-40, Rua Comendador Torlogo Dauntre, 74, sala 1207, Cambuí, Campinas – SP, 13027-250, Brazil ("we", "us"). These Terms form a contract between you and us covering your use of the Service. By creating an account or using Fukurō you accept them. If you do not accept them, do not use the Service.

Eligibility: You must be at least 18 years old and able to enter into a binding contract. If you are using Fukurō on behalf of an institution, you confirm you are authorised to bind it.

Changes to these Terms: We may update these Terms as the Service changes. If a change materially affects your rights or obligations, we will notify you by email or in the app at least 30 days before it takes effect, and you may cancel before then if you do not accept it. Changes required by law may take effect sooner.

What the Service Does

Fukurō provides AI-generated analysis of academic manuscripts and related workflows. The Service includes:

• Automated first-pass review across multiple review dimensions
• Line-level language check for grammar, clarity, and cohesion
• Citation format verification
• Detailed improvement recommendations
• Rebuttal assistance, including analysis of reviewer feedback and checks of revisions against it
• Manuscript version comparison between uploaded revisions
• Interactive chat for follow-up questions about completed analyses

Rebuttal assistance: Rebuttal features help you interpret reviewer comments, plan revisions, and assess whether changes may address stated concerns. Outputs are suggestions and organisational aids only. You remain solely responsible for the substance, accuracy, and tone of anything you submit to editors, reviewers, or institutions, and for complying with their policies on revisions and AI use.

Manuscript version comparison: Comparison features highlight differences between uploaded versions. Diffs and summaries are generated automatically and may miss formatting, figures, tables, equations, or substantive meaning. Verify all comparisons against your source documents before relying on them.

Review and rebuttal chat: After certain analyses complete you may ask follow-up questions in chat. Chat context includes excerpts of your manuscript, not only the review report. Responses are AI-generated, may be incomplete or incorrect, and are not professional, legal, or editorial advice.

Fukurō provides suggestions and analysis only. It does not guarantee acceptance by any journal or publication, a favourable outcome in peer review, or that a rebuttal or revision will satisfy editors or reviewers.

Acceptable Use and Academic Integrity

You agree to:

• Provide accurate account information and keep your credentials secure
• Not share your account with others
• Use the Service only for lawful purposes
• Not attempt to reverse engineer, disrupt, or circumvent limits on the Service
• Review and verify every AI-generated output before relying on or sharing it

You must not:

• Submit any Fukurō output, in whole or in part, as your own peer review to a journal, conference, funder, or institution. Fukurō simulates peer review for the author's own use; it is not a substitute for a review you have been asked to write.
• Upload a manuscript that you have received to peer-review, or that is otherwise subject to a confidentiality obligation you owe to a third party.
• Use the Service in breach of any journal, conference, funder, employer, or institutional policy on the use of AI, including disclosure requirements.
• Upload content you do not have the right to share, including content owned by co-authors or third parties who have not agreed to it.
• Upload personal data of research participants or other individuals without a lawful basis for doing so.

Your warranty: Each time you upload content or request an analysis, you warrant that you hold the rights necessary to do so, that you are not breaching any confidentiality obligation, and that your use complies with the AI policies of any journal, institution, or funder that applies to your work. Breach of this section is a material breach and we may suspend or terminate your account under "Suspension and Termination" below.

Your Content and Our Content

Your content: You keep all rights in the manuscripts and other content you upload. You grant us a limited, non-exclusive licence to host, process, and transmit that content solely to provide the Service to you — including sending it to the AI providers named in our Privacy Policy. This licence ends when the content is deleted. We do not use your manuscripts to train our own models.

Our content: The Service, including its software, prompts, review methodology, and interface, is protected by intellectual property law. You may not copy, modify, resell, or create derivative services from it without our written permission.

AI-generated output: Subject to your compliance with these Terms, you may use the analyses generated for you for any lawful purpose connected to your own work. Because AI output is not the product of human authorship, we make no claim that it is protectable by copyright, and we cannot guarantee it is unique to you.

AI providers: Producing an analysis requires sending your content to third-party AI providers. Our Privacy Policy names each of them and explains which are used by default and which require your explicit consent.

Plans, Credits, and Payment

Pricing: Current pricing is shown on our Pricing page. We may change prices with at least 30 days' notice to existing subscribers; the new price applies from your next renewal.

Credits: Analyses are paid for with credits, whether purchased directly or included with a subscription. Credits expire one year after they are granted, and are consumed oldest-first. Credits have no cash value and cannot be transferred between accounts.

Payment: Payments are processed by Stripe. Subscriptions renew automatically for the interval you chose until cancelled.

Automatic top-up: If you enable automatic top-up, we will prompt you to complete a payment when your balance falls below the threshold you set. We do not charge a stored card without your action. You can disable it at any time in your billing settings.

Failed analyses: If an analysis fails on our side after credits have been deducted, we return those credits to your balance once retries are exhausted. Returned credits carry a fresh one-year expiry.

Cancellation, Refunds, and Withdrawal

Cancelling a subscription: You can cancel at any time from your account settings. Cancellation takes effect at the end of the current billing period; you keep access until then. Credits already granted remain usable until they expire.

Statutory right of withdrawal: If you are a consumer in Brazil, you may withdraw from a purchase within 7 days of contracting it (Consumer Protection Code, art. 49). If you are a consumer in the EU/EEA, the period is 14 days. In either case we refund credits you have not yet used. Where you asked us to begin an analysis immediately and it has started, that analysis is not refundable, because you expressly requested performance before the withdrawal period expired.

Deleting your account: You can delete your account from your settings. We cancel any active subscription and delete your account data immediately. Invoices and payment records are kept for the periods required by tax and accounting law. Export any analyses you wish to keep before deleting, because deletion cannot be undone.

Institutional Accounts

Where an institution pays for or administers accounts, the institution is our contracting party for billing purposes and may manage seats, including removing them. Individual users remain responsible for their own compliance with the Acceptable Use section. Institution administrators do not have access to the content of members' manuscripts, reviews, or chats. Institutional arrangements may be governed by a separate written agreement, which prevails over these Terms where they conflict.

Disclaimers

Provided as is: Except for warranties that cannot be excluded under applicable law — including the Brazilian Consumer Protection Code — the Service is provided "as is" and "as available", and we disclaim implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

No guarantee of acceptance: We do not guarantee acceptance by any journal, conference, or publication, or any particular outcome in peer review.

AI limitations: Our analysis — including review reports, rebuttal assistance, version comparisons, and chat — is generated by AI models. It may omit real problems, report problems that do not exist, misinterpret reviewer comments, misstate differences between versions, or state something inaccurate with apparent confidence. You are responsible for reviewing all output and for every decision you make about your manuscript.

Availability: We aim to keep the Service available continuously but do not commit to a specific uptime level. The Service may be unavailable for maintenance, provider outages, or technical faults.

Limitation of Liability

What we never limit: Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, including liability for fraud, wilful misconduct, death or personal injury, or any liability owed to consumers under the Brazilian Consumer Protection Code.

Otherwise: To the maximum extent permitted by law, we are not liable for indirect, incidental, special, or consequential damages, or for lost profits, lost data, or lost publication or funding opportunities. Where liability may lawfully be capped — which, for consumers in Brazil, it generally may not — our total liability for any claim is limited to the greater of the amounts you paid us in the 12 months before the claim arose, or BRL 500.

Indemnity

If you are not a consumer, you agree to indemnify us against claims, losses, and reasonable legal costs arising from content you upload, from your breach of the Acceptable Use section, or from your breach of a confidentiality or institutional obligation. We will tell you promptly about any such claim and will not settle it without your agreement.

Suspension and Termination

We may suspend or terminate your account if you materially breach these Terms — in particular the Acceptable Use section — or if we are required to by law. Except where a delay would cause harm or is legally prohibited, we will tell you why and give you a chance to put things right. If we terminate your account without cause, we refund unused credits and the unused part of any prepaid subscription period. You may stop using the Service and delete your account at any time.

Data Protection

Our Privacy Policy explains what we collect, which AI providers and other processors receive your content, how long we keep it, and how to exercise your rights under the LGPD and the GDPR. It forms part of these Terms.

Governing Law and Where Disputes Are Heard

These Terms are governed by the laws of Brazil. If you are a consumer, you may bring proceedings in the courts of your own domicile, as guaranteed by article 101, I of the Consumer Protection Code, and nothing here requires you to arbitrate. If you are not a consumer, the courts of Campinas, São Paulo, Brazil have exclusive jurisdiction.

General

Severability: If any provision is held unenforceable, the rest remains in force and the unenforceable provision is applied to the fullest extent permitted.

Entire agreement: These Terms and the Privacy Policy are the whole agreement between us about the Service, and replace any earlier terms.

Assignment: You may not transfer your rights under these Terms without our consent. We may transfer ours to a successor in connection with a merger, acquisition, or sale of assets, provided your rights are not reduced.

No waiver: If we do not enforce a provision, that is not a waiver of our right to enforce it later.

Events outside our control: We are not liable for failure to perform caused by events beyond our reasonable control, including outages at the AI providers and infrastructure suppliers the Service depends on.

Notices: We contact you at the email address on your account. You can reach us at the addresses below. Keep your email address current.

Survival: The sections on your content, disclaimers, limitation of liability, indemnity, governing law, and this General section survive termination.

Language: These Terms are published in English, Portuguese, and Spanish. For consumers resident in Brazil, the Portuguese version prevails. For everyone else, the English version prevails.
