VesselTwin Terms of Service
Effective 2026-05-24 — v1.1, under legal review
Version 1.1, effective 2026-05-24 — draft pending review
These terms are under licensed legal review and may be updated. Material changes will be announced; the effective date at the top will move. If you have questions, contact legal@vesseltwin.io.
1. Acceptance and changes
These Terms of Service (the "Terms") govern your access to and use of VesselTwin (the "Service") operated by VesselTwin ("VesselTwin", "we", "us"). By creating an account or using the Service you accept these Terms. If you do not accept them, do not use the Service.
We may update these Terms. Material changes will be notified by email to your account address and by an in-app banner. The "Effective" date at the top of this page will move. Continued use after the new effective date constitutes acceptance of the updated Terms. If you do not accept an update, your remedy is to stop using the Service and delete your account.
2. What the Service is and is not
VesselTwin is a digital record-keeping product. It lets you record, store, share, and search your vessel's configuration, photos, documents, measurements, parts, and maintenance history.
VesselTwin is not a substitute for a certified marine surveyor, a licensed mechanic, a marine engineer, a coast-guard inspection, or any other professional safety, regulatory, or engineering service. Information in VesselTwin is best-effort, may be inaccurate or incomplete, and may have been extracted from documents by AI. You alone are responsible for safety, maintenance, fitment, and regulatory decisions affecting your vessel.
3. Eligibility
- You must be at least 18 years old.
- You must not be a person ordinarily resident in, or otherwise subject to, the jurisdiction of a country or entity subject to comprehensive U.S. or E.U. sanctions (including, without limitation, OFAC-listed countries and persons).
- The Service is not intended for use by regulated commercial maritime operators without a separate written agreement with VesselTwin.
4. Account responsibility
Accounts are for individual humans. One human per account. You may not use a bot, automation framework, or scripted agent to access the Service except via interfaces VesselTwin explicitly publishes for that purpose. You may not share your credentials. You are responsible for all activity under your account. Notify us promptly at security@vesseltwin.io if you suspect unauthorized access.
5. Plans and payment
VesselTwin currently offers an individual plan and a Pro plan. The individual plan is free of charge, subject to a vessel-count limit. The Pro plan is a paid tier (terms to be added when paid billing is enabled). You can change plans from the in-app settings. Free-to-paid upgrades and any associated billing terms will be presented to you before any charge is made.
6. Your content
You retain ownership of the content you upload to the Service (your Content). You grant VesselTwin a worldwide, non-exclusive, royalty-free license to host, store, copy, process, transmit, display, analyze, de-identify, aggregate, create derivative works from, and otherwise use your Content as needed to provide, secure, support, improve, and develop the Service; to power AI extraction and related product features; to create benchmarks, catalog intelligence, model-level patterns, predictive-maintenance signals, and other derived insights; and to create, use, license, sell, or otherwise commercialize aggregated or de-identified data products as described in the Privacy Policy. We may sublicense this license to subprocessors, contractors, and service providers only as needed for those permitted purposes.
You represent and warrant that (a) you have all rights necessary to upload your Content, (b) your Content does not infringe any third-party right, (c) you have any consents required from persons depicted in photos or named in documents, and (d) you have the right to subject your Content to AI processing by VesselTwin's subprocessors. See our subprocessor list for the processors involved.
Aggregated, de-identified, anonymized, statistical, inferred, or derived outputs created from the Service are not your Content when they do not reasonably identify you, your account, your household, or a non-public vessel. VesselTwin may use and commercialize those outputs without paying compensation to you, subject to the Privacy Policy and applicable law.
If you submit Content to a public catalog, community feature, benchmark program, or other opt-in contribution flow, you also grant VesselTwin the right to publish, distribute, adapt, license, and commercialize that submitted Content and related derived insights according to the notice shown in that flow.
7. AI-assisted features
VesselTwin uses AI to extract structured data from documents and photos you upload. Extraction is best-effort. Extracted values may be inaccurate, incomplete, or hallucinated. VesselTwin does not guarantee accuracy. You must verify against the original document before relying on extracted values for any decision — especially maintenance, safety, fitment, or regulatory compliance.
AI-extracted content is labeled in the product so you can identify it before relying on it. AI processing by our subprocessors is subject to no-training defaults as documented in the subprocessor list.
We may use AI-extracted outputs, user corrections, and de-identified or aggregated patterns to improve VesselTwin's extraction logic, prompts, validation rules, catalog intelligence, benchmark reports, predictive-maintenance signals, and other data products. This does not authorize AI subprocessors to train their general models on your inputs except as described in the Privacy Policy and only with any notices, consents, or opt-outs required by law.
8. Sharing and recipients
You can share subsets of your vessel data with vendors, brokers, prospective buyers, or anyone else by creating a share link. Share links expire automatically after no more than 30 days and can be revoked at any time. Each recipient must accept our Recipient Terms before viewing the shared content. Recipient access is logged so you can see who opened what.
9. Vendor disclaimer
The Service may surface vendors, contractors, or other third parties. VesselTwin does not endorse, certify, vet, or warrant any vendor or any vendor's work. There is no agency relationship between VesselTwin and any vendor. VesselTwin is not responsible for the accuracy of vendor estimates or completion notes, the quality of vendor work, or any dispute between you and a vendor.
10. Acceptable Use
You agree not to use the Service to:
- 10.1 Upload, share, or distribute content that is illegal, harassing, threatening, defamatory, obscene, sexually explicit material involving minors, or otherwise objectionable.
- 10.2 Impersonate any person or entity, or misrepresent your affiliation with a person or entity.
- 10.3 Scrape, mass-download, index, or otherwise harvest the Service or its content; reverse-engineer, decompile, or disassemble the Service or any part of it.
- 10.4 Use the Service's inputs, outputs, or any data obtained from the Service to train, fine-tune, evaluate, or otherwise improve any machine-learning model, foundation model, or competing service.
- 10.5 Upload copyrighted material you do not have rights to. VesselTwin honors valid notices under the U.S. Digital Millennium Copyright Act — see our DMCA Notice and Takedown Policy.
- 10.6 Resell, sublicense, or commercially repackage the Service without VesselTwin's prior written consent.
- 10.7 Bypass, disable, or interfere with any security or access control of the Service.
We may suspend or terminate accounts that violate these Acceptable Use rules. Repeat copyright infringers are locked out under our DMCA repeat-infringer policy.
11. Trademark notice
Manufacturer names, model names, brand names, and logos that appear in the catalog or in user-uploaded content are the property of their respective owners. VesselTwin is not affiliated with, endorsed by, or sponsored by any manufacturer named in the Service. References to manufacturers are made for the sole purpose of identifying equipment and helping owners find compatible information.
12. Reminders and notifications
VesselTwin can send reminders (maintenance due, service intervals, etc.) by email, push notification, or — if you opt in — SMS. Reminders are best-effort. VesselTwin makes no guarantee that any reminder will be delivered, will be delivered on time, or will reach you. You are solely responsible for vessel maintenance and safety decisions. Do not rely on VesselTwin reminders as your only notification mechanism for safety-critical maintenance.
13. Beta posture and feedback
The Service is currently offered as a beta. Features may be added, modified, or removed at any time without notice. Some features may be unstable, may produce incorrect results, or may be withdrawn.
If you submit feedback, suggestions, or ideas via the Service, you grant VesselTwin a perpetual, worldwide, royalty-free, irrevocable license to use that feedback for any purpose without obligation to you, including incorporating it into the Service. Feedback is not your Content; it is licensed under this paragraph rather than under §6.
14. Warranty disclaimer
THE SERVICE AND ALL CONTENT, FEATURES, AND MATERIALS PROVIDED THROUGH THE SERVICE ARE PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, VESSELTWIN DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, COMPLETENESS, AND QUIET ENJOYMENT.
VESSELTWIN MAKES NO WARRANTY THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT ANY DATA WILL BE ACCURATE, COMPLETE, OR FIT FOR SAFETY-CRITICAL USE. THE SERVICE IS NOT A SUBSTITUTE FOR A CERTIFIED MARINE SURVEYOR, A LICENSED MECHANIC, A MARINE ENGINEER, A COAST-GUARD INSPECTION, OR ANY OTHER PROFESSIONAL INSPECTION. YOU ASSUME THE ENTIRE RISK OF USING THE SERVICE FOR ANY DECISION AFFECTING SAFETY, REGULATORY COMPLIANCE, OR PROPERTY.
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES. TO THE EXTENT REQUIRED BY APPLICABLE LAW, THE EXCLUSIONS ABOVE DO NOT APPLY TO YOU.
15. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, VESSELTWIN'S AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS IS LIMITED TO THE GREATER OF (A) THE AMOUNTS YOU PAID VESSELTWIN FOR THE SERVICE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR (B) USD 100.
VESSELTWIN SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOST PROFITS, LOST REVENUE, LOST DATA, OR COSTS OF SUBSTITUTE SERVICES, EVEN IF VESSELTWIN HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
THE LIMITS IN THIS SECTION DO NOT APPLY TO (i) VESSELTWIN'S INFRINGEMENT OF YOUR INTELLECTUAL PROPERTY RIGHTS, (ii) BREACH OF CONFIDENTIALITY OBLIGATIONS OWED TO YOU, (iii) GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, OR (iv) ANY LIABILITY THAT CANNOT BE LIMITED OR EXCLUDED UNDER APPLICABLE LAW. SOME JURISDICTIONS DO NOT ALLOW THESE LIMITATIONS; IN SUCH JURISDICTIONS THE LIMITS APPLY TO THE FULLEST EXTENT PERMITTED BY LAW.
16. Indemnification
16.1 By you. You will indemnify, defend, and hold harmless VesselTwin and its officers, directors, employees, contractors, and agents from and against any third-party claim, demand, loss, liability, damage, cost, or expense (including reasonable attorneys' fees) arising out of or relating to: (a) your Content, (b) your use of the Service in breach of these Terms, (c) claims by persons depicted in photos or named in documents you uploaded, (d) third-party intellectual-property claims arising from your Content, and (e) your violation of applicable law.
16.2 By VesselTwin. Subject to §15, VesselTwin will defend you against third-party intellectual-property infringement claims arising solely from platform-provided content (for example, the shared catalog), and pay damages finally awarded against you for such claims. This obligation does not apply to claims arising from your Content, your combination of platform content with other materials, or your use of the Service in violation of these Terms.
17. Suspension and termination
VesselTwin may suspend or terminate your account if you violate these Terms, if we reasonably believe your conduct creates legal risk for us or our users, or if we are compelled by law. We will give notice where practical. You may terminate at any time by deleting your account. Sections 6 (Your Content — previously created aggregated or de-identified outputs, public or opt-in contributions, and wind-down uses), 10 (Acceptable Use), 14 (Warranty), 15 (Liability), 16 (Indemnification), 19 (Governing Law), 20 (Arbitration), and 23 (Miscellaneous) survive termination.
18. Modifications to the Service
We may modify, suspend, or discontinue all or part of the Service at any time. For paid features that you have already paid for, we will provide reasonable advance notice and a pro-rata refund where required by law.
19. Governing law and venue
These Terms are governed by the laws of the State of Delaware, U.S.A., without regard to its conflict-of-law principles. Subject to the arbitration provision in §20, any dispute arising out of or relating to these Terms or the Service that is not subject to arbitration shall be filed exclusively in the state or federal courts located in Delaware, and the parties consent to personal jurisdiction in those courts.
20. Arbitration and class-action waiver (U.S. users)
20.1 Binding arbitration. Except as set out below, any dispute arising out of or relating to these Terms or the Service will be resolved by binding arbitration administered by JAMS or the American Arbitration Association under their then-current commercial arbitration rules, in Delaware. Judgment on the award may be entered in any court of competent jurisdiction. The arbitrator will have exclusive authority to resolve disputes about the scope, applicability, or enforceability of this arbitration agreement.
20.2 Class-action waiver. You and VesselTwin each agree to bring disputes only in your individual capacity. Neither of you nor VesselTwin will be a plaintiff or class member in any purported class, consolidated, or representative action.
20.3 Carve-outs. Either party may bring an individual action in small-claims court for disputes within that court's jurisdiction, and either party may seek injunctive or other equitable relief from a court of competent jurisdiction to protect intellectual-property rights.
20.4 EU consumers. If you are a consumer ordinarily resident in the European Union or the United Kingdom, this §20 does not apply to you, your statutory consumer rights are not affected, and you may bring proceedings in the courts of your country of residence.
21. Communications
We send three categories of communications: transactional (account security, billing, share-link activity — required to deliver the Service), service (reminders, scheduled-deletion notices — sent based on your configured preferences), and marketing-adjacent (product announcements and similar — only with explicit consent). You can manage service-category preferences from in-app settings. Marketing-category communications include an unsubscribe link in every message.
22. Privacy
Our Privacy Policy describes how we collect, use, and share information about you. By using the Service you accept the Privacy Policy.
23. Miscellaneous
Entire agreement. These Terms, together with the policies they reference (Privacy, Recipient Terms, DMCA, Cookies, Subprocessors, Account-Deletion), are the entire agreement between you and VesselTwin regarding the Service. Severability. If any provision is held unenforceable, the remaining provisions stay in effect. No waiver. Our failure to enforce a provision is not a waiver of our right to enforce it later. Assignment. You may not assign these Terms without our written consent. We may assign them in connection with a merger, acquisition, or sale of assets. Force majeure. Neither party is liable for failure or delay caused by events beyond reasonable control. Headings are for convenience only. Electronic communications. You consent to receive communications from us electronically. Notices to VesselTwin should be sent to the postal address in §24.
