Terms of Service

Last updated: September 13, 2026 · Effective: September 13, 2026

These Terms of Service ("Terms") are a binding agreement between you and Neurojourney, Inc. ("Neurojourney", "we", "us") governing your use of Neutropic — the web app at neutropic.io, the desktop and mobile apps, the API and the documentation (together, the "Service"). Please read them together with our Privacy Policy. If you do not agree, do not use the Service.

1. Acceptance and eligibility

  1. 1.1
    By creating an account, clicking "I agree", or using the Service, you accept these Terms. If you use the Service on behalf of a university, company or other organization, you represent that you are authorized to bind it, and "you" includes that organization.
  2. 1.2
    You must be at least 18 years old, or the age of majority where you live, to create an account. The Service is not directed to children; if you are under 14 (Republic of Korea) or the applicable minimum age elsewhere, you may not use it.
  3. 1.3
    Where these Terms conflict with mandatory consumer-protection law in your country, that law prevails to the extent of the conflict.

2. The Service

  1. 2.1
    Neutropic is an AI research agent for the human sciences. It runs research workflows — literature search, hypothesis generation, experiment design, data analysis, statistics, figure generation, manuscript drafting and review — using large language models, a code-execution sandbox, and third-party data sources and connectors you authorize.
  2. 2.2
    The desktop app can read files and run analysis code on your own computer through a local helper; the web app processes uploads in your private account workspace on our servers. Some features are labelled beta, preview or experimental and may change, be limited or be withdrawn at any time. We may also modify or discontinue features generally, with reasonable notice where the change is material to paid plans.

3. Accounts and security

  1. 3.1
    You need an account to use most of the Service. Keep your credentials confidential, use accurate and current information, and notify us at contact@neurojourney.ai promptly if you suspect unauthorized use. You are responsible for all activity under your account, including activity by people you allow to use it.
  2. 3.2
    We may suspend an account that we reasonably believe is compromised, violates these Terms, or poses a security or legal risk to the Service or other users.

4. Plans, credits and billing

  1. 4.1
    The Service offers a free plan and paid subscription plans (currently Lite, Pro and Max) described at neutropic.io/pricing. Each plan includes a monthly allowance of managed cloud credits, a daily usage cap and a storage quota. Credits reset on your billing date and unused credits do not roll over. Using local models or your own model API keys is not metered against credits.
  2. 4.2
    Paid plans are sold by Paddle.com Market Ltd. ("Paddle"), our authorized reseller and merchant of record. Your purchase is also subject to Paddle's Buyer Terms, which include Paddle's refund policy. Prices are shown before checkout in USD or, for Korean customers, KRW; applicable taxes (VAT/sales tax) are added or included as required by law and shown at checkout.
  3. 4.3
    Subscriptions renew automatically at the end of each billing period (monthly or yearly) at the then-current price until cancelled. You can cancel at any time from Upgrade plan (/plan); cancellation takes effect at the end of the current period and you keep access until then. Plan upgrades take effect immediately; downgrades take effect at the next renewal.
  4. 4.4
    We will give you at least 30 days' notice by email or in the Service before a price increase that affects your next renewal. If you do not agree to the new price you may cancel before it takes effect.
  5. 4.5
    Promotion codes and discount coupons are subject to the conditions stated when issued (expiry, plan, single use per account). Credits granted by promotion codes have no cash value, are non-transferable and may be withdrawn if obtained fraudulently.
  6. 4.6
    If a payment fails, we may retry it and, after notice, suspend paid features until payment succeeds. You are responsible for any bank or currency-conversion fees charged by your payment provider.

5. Refunds and withdrawal

  1. 5.1
    Paddle's 14-day refund policy applies to every purchase: if you are not satisfied with a paid plan you may request a full refund within 14 days of the charge — including a renewal charge — by contacting contact@neurojourney.ai or Paddle at paddle.net. Refunds are returned to the original payment method. A refund may be declined where the request is made after the 14-day window, where refunds are requested repeatedly, or where we or Paddle reasonably suspect abuse.
  2. 5.2
    Consumers in the Republic of Korea may withdraw from a purchase within 7 days under the Act on Consumer Protection in Electronic Commerce; consumers in the EEA and UK have a 14-day right of withdrawal. Because the Service starts immediately after purchase, by purchasing you request immediate performance and acknowledge that, once credits included in the plan have been used, the refund may be reduced proportionally to the extent permitted by law. Nothing in this section limits statutory refund rights that apply where you live.

6. Acceptable use

  1. 6.1
    You agree not to use the Service to:
    • (a) violate any law or the rights of others
    • (b) process personal data, including research participants' data, without a lawful basis and the consents, approvals (e.g. IRB/ethics committee) and safeguards your research requires
    • (c) upload malware or content that is unlawful, infringing or harmful
    • (d) probe, scan or test the vulnerability of the Service, bypass rate limits, daily caps, storage quotas or access controls, or interfere with its operation
    • (e) scrape or bulk-extract the Service or its outputs to build a competing product or to train a model
    • (f) share or resell access to your account or plan
    • (g) impersonate others or misrepresent the source of content
    • (h) use the Service for automated decisions that produce legal or similarly significant effects on individuals without human review
  2. 6.2
    Third-party data sources reachable through the Service (literature databases, patent offices, web pages, Google Drive and other connectors) have their own terms, licences and rate limits. You are responsible for complying with them, including any restrictions on redistributing retrieved content.
  3. 6.3
    We may remove content, throttle usage or suspend access that we reasonably believe violates this section, and we may report unlawful activity to authorities.

7. Your content

  1. 7.1
    "Your Content" means the files you upload, the prompts you send, project memory, and the artifacts (reports, tables, figures, manuscripts, code) the Service generates for you. As between you and us, you own Your Content. We claim no rights in it beyond the licence below.
  2. 7.2
    You grant us a worldwide, non-exclusive, royalty-free licence to host, store, process, transmit, display and back up Your Content solely to provide, secure and improve the Service for you and as described in the Privacy Policy. We do not use Your Content to train machine-learning models and do not share it with other customers. The licence ends when you delete the content or your account, except for backups retained for a limited period and copies we must keep by law.
  3. 7.3
    You are responsible for Your Content: for having the rights, consents and approvals needed to upload and process it, and for its accuracy. Support staff may access Your Content only to resolve a problem you report, to investigate abuse or as required by law; such access is logged.
  4. 7.4
    If you send us feedback or suggestions, we may use them without obligation to you.

8. AI-generated output

  1. 8.1
    Outputs are generated by artificial-intelligence models and automated pipelines. Despite built-in checks (assumption tests, citation verification, review steps), outputs may be inaccurate, incomplete, out of date or inappropriate for your purpose, and similar outputs may be produced for other users. You must independently verify results — including statistics, citations and figures — before relying on them in publications, grant applications, clinical, safety-related or other consequential decisions.
  2. 8.2
    The Service is a research tool. It does not provide medical, legal, financial or other professional advice, and using it does not create a professional relationship. Where a journal, funder or institution requires disclosure of AI assistance, you are responsible for making it.
  3. 8.3
    Models are provided by third parties (for example Google, Anthropic and OpenAI). Their availability, behaviour and pricing may change, and your use of a model through the Service must comply with that provider's usage policies.

9. Connectors and third-party services

  1. 9.1
    Connectors (for example Google Drive) and platform credentials (for example Scopus or Qualtrics tokens) let the Service act on third-party services with your authorization. Those services are governed by their own terms and privacy policies; your use of them is between you and the provider. Every connector tool starts as "Ask each time" and you control what the agent may do. We are not responsible for third-party services, their content or their availability.
  2. 9.2
    The Service includes open-source software licensed under its own terms, which are available on request.

10. Our intellectual property

  1. 10.1
    The Service — including its software, skills, prompts, models of workflow, documentation, design and the Neutropic and Neurojourney names and logos — is owned by Neurojourney or its licensors and protected by intellectual-property laws. Except for the rights expressly granted to you, we reserve all rights. You may not copy, modify, reverse-engineer, decompile or create derivative works of the Service except where the law allows despite this restriction.
  2. 10.2
    We respect intellectual-property rights. If you believe content available through the Service infringes your copyright, send a notice with the material identified, your contact details and a statement of good-faith belief to contact@neurojourney.ai; we will respond and, where appropriate, remove or disable access to the material.

11. Availability, support and changes

  1. 11.1
    We aim for high availability but do not guarantee uninterrupted or error-free operation. Maintenance, provider outages, rate limits and factors outside our control may make the Service temporarily unavailable. Support is provided by email (contact@neurojourney.ai) and, for paid plans, as described on the pricing page; response times are targets, not guarantees.
  2. 11.2
    We may update the Service and these Terms. For material changes to these Terms we will give at least 30 days' notice (7 days for changes required by law or that do not reduce your rights) by posting on this page and, where we have your address, by email. If you continue to use the Service after the effective date you accept the changes; if you do not agree, cancel your plan and stop using the Service before then.

12. Term, suspension and termination

  1. 12.1
    These Terms apply from the moment you first use the Service until your account is deleted. You may delete your account at any time from Customize → General; this ends any paid plan without a refund of the current period unless Section 5 applies.
  2. 12.2
    We may suspend or terminate your access with notice if you materially breach these Terms and do not cure the breach within 14 days of notice (immediately for breaches that cannot be cured or that create legal or security risk), if required by law, or if we discontinue the Service — in which case we will give at least 30 days' notice and, for prepaid periods not yet delivered, a pro-rata refund.
  3. 12.3
    After termination you may export Your Content for 30 days unless we are legally prevented from allowing it; afterwards we delete it as described in the Privacy Policy. Sections 7 (licence to the extent needed for backups), 8, 10, 13, 14, 15 and 16 survive termination.

13. Disclaimers

  1. 13.1
    To the maximum extent permitted by law, the Service is provided "as is" and "as available" without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, non-infringement and uninterrupted operation. Some jurisdictions do not allow the exclusion of certain warranties; in that case the exclusions apply only to the extent permitted.

14. Limitation of liability

  1. 14.1
    To the maximum extent permitted by law, Neurojourney and its officers, employees, contractors and suppliers are not liable for indirect, incidental, special, consequential or punitive damages, or for loss of profits, revenue, data, research results or goodwill, arising out of or related to the Service or these Terms, even if advised of the possibility.
  2. 14.2
    Our total liability for all claims relating to the Service in any 12-month period is limited to the greater of the amounts you paid us for the Service in the 12 months before the event giving rise to the claim or USD 100.
  3. 14.3
    These limits do not apply to liability that cannot be limited by law, including liability for death or personal injury caused by negligence, fraud, or intentional or grossly negligent breach.

15. Indemnity

  1. 15.1
    If you are using the Service on behalf of an organization or for commercial purposes, you will defend and indemnify Neurojourney against third-party claims, and the resulting damages and reasonable costs, to the extent arising from Your Content, your research activities, or your breach of Sections 6 or 7. Consumers are liable only under the general law.

16. Governing law and disputes

  1. 16.1
    These Terms are governed by the laws of the Republic of Korea, excluding its conflict-of-law rules. The courts of the Republic of Korea, with the Seoul Central District Court as the court of first instance where the Civil Procedure Act allows, have jurisdiction over disputes arising from these Terms. If you are a consumer, you also keep the protection of the mandatory laws and the courts of the country where you habitually reside.
  2. 16.2
    Before starting formal proceedings, please contact us — most issues can be resolved quickly. Consumers in the Republic of Korea may also apply to the Korea Consumer Agency or the Electronic Commerce Mediation Committee; consumers in the EU may use the European Commission's online dispute-resolution platform.

17. General

  1. 17.1
    Export control and sanctions: you may not use the Service in violation of export-control or sanctions laws, or if you are on a restricted-party list.
  2. 17.2
    • Entire agreement: these Terms, the Privacy Policy and the plan descriptions on the pricing page are the entire agreement between you and us about the Service and replace prior agreements.
    • Severability: if a provision is unenforceable, the rest remains in effect.
    • No waiver: our failure to enforce a provision is not a waiver.
    • Assignment: you may not assign these Terms without our consent; we may assign them to an affiliate or successor.
    • Force majeure: neither party is liable for delays caused by events beyond its reasonable control.
    • Electronic communications: we may send notices to the email address on your account.
  3. 17.3
    Language: these Terms are written in English; translations are provided for convenience and the English version governs if they conflict.
