HELMWISE IS A SUPPLEMENTARY PLANNING TOOL ONLY. IT IS NOT A SUBSTITUTE FOR PROPER SEAMANSHIP, PROFESSIONAL NAVIGATION, OFFICIAL CHART WORK, OR SOUND MARINER JUDGMENT.
All passage plans, weather data, tidal predictions, safety assessments, and recommendations generated by Helmwise are provided for informational and planning assistance purposes only. Mariners must independently verify all information against official sources and exercise their own professional judgment before and during any voyage. You assume full responsibility for all navigation decisions.
By accessing or using Helmwise (the “Service”), operated by Helmwise (“we,” “us,” or “our”), you agree to be bound by these Terms of Service (“Terms”). If you do not agree to these Terms, you must not use the Service. We reserve the right to modify these Terms at any time. Continued use of the Service after changes constitutes acceptance of the updated Terms.
Helmwise is an AI-powered passage planning platform that aggregates data from various third-party sources (including but not limited to NOAA, National Weather Service, OpenWeather, and NDBC buoy networks) and processes it through specialized AI agents to generate passage plans, weather analyses, tidal predictions, safety assessments, and route recommendations.
The Service is intended solely as a supplementary planning aid. It is designed to assist mariners in their passage planning process, not to replace any aspect of professional navigation, official chart work, seamanship, or mariner judgment.
THIS SECTION CONTAINS CRITICAL SAFETY INFORMATION. PLEASE READ IT CAREFULLY.
Helmwise does not replace and must not be used as a substitute for:
All data, recommendations, and passage plans generated by Helmwise are produced by artificial intelligence systems and automated data processing. These outputs may contain errors, inaccuracies, omissions, or outdated information. Specifically:
Helmwise aggregates data from third-party sources over which we have no control. These data sources may experience outages, delays, errors, or discontinuation at any time without notice. We do not guarantee the accuracy, completeness, timeliness, or availability of any third-party data. When data sources conflict, the Service attempts to present worst-case scenarios, but this process is automated and may not always function correctly.
You, as the mariner and master of your vessel, bear sole and complete responsibility for:
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, COMPLETENESS, RELIABILITY, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS. WE MAKE NO WARRANTY REGARDING THE ACCURACY OR RELIABILITY OF ANY INFORMATION OBTAINED THROUGH THE SERVICE.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, HELMWISE, ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, PARTNERS, AND LICENSORS SHALL NOT BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO DAMAGES FOR:
This limitation applies regardless of the theory of liability (contract, tort, negligence, strict liability, or otherwise), even if we have been advised of the possibility of such damages.
In no event shall our total aggregate liability to you exceed the amount you have paid to us for the Service in the twelve (12) months preceding the event giving rise to the claim, or one hundred US dollars ($100), whichever is greater.
You agree to indemnify, defend, and hold harmless Helmwise, its officers, directors, employees, agents, partners, and licensors from and against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys' fees) arising out of or relating to:
Maritime navigation is inherently dangerous. By using the Service, you expressly acknowledge and assume all risks associated with maritime navigation, including but not limited to risks of adverse weather, sea conditions, equipment failure, navigational hazards, and human error. You understand that the Service cannot eliminate or fully mitigate these risks, and you agree that your use of the Service is entirely at your own risk.
You represent and warrant that you possess adequate training, experience, qualifications, and certifications for the voyages you plan using the Service, and that you will not undertake any voyage for which you or your vessel are not adequately prepared, regardless of any assessment provided by the Service.
You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You agree to notify us immediately of any unauthorized use. We reserve the right to suspend or terminate accounts at our discretion.
Paid subscriptions are billed in advance on a monthly or annual basis. You may cancel at any time, and access will continue through the end of your current billing period. Refunds are provided at our sole discretion. All prices are in US dollars and are subject to change with 30 days' notice.
The Service, including all software, content, design, and documentation, is owned by Helmwise and protected by intellectual property laws. You are granted a limited, non-exclusive, non-transferable license to use the Service in accordance with these Terms. Passage plans and exports generated for your use are yours to keep and use.
Your use of the Service is also governed by our Privacy Policy. We collect route data, vessel information, and usage analytics to improve the Service. We do not sell personal data to third parties. Voyage data may be retained for safety audit purposes.
You agree not to use the Service:
We do not guarantee continuous, uninterrupted access to the Service. The Service may be unavailable due to maintenance, updates, or circumstances beyond our control, including data source outages. You should never depend on the availability of the Service during a voyage. Always have alternative passage planning resources available.
We may terminate or suspend your access to the Service at any time, with or without cause, with or without notice. Upon termination, your right to use the Service ceases immediately. Sections 3 through 6 (disclaimers, limitation of liability, indemnification, and assumption of risk) shall survive termination.
These Terms shall be governed by and construed in accordance with the laws of the United States. Any disputes arising from these Terms or the use of the Service shall be resolved through binding arbitration in accordance with the rules of the American Arbitration Association. You agree to waive any right to a jury trial or to participate in a class action.
If any provision of these Terms is found to be unenforceable or invalid, that provision shall be limited or eliminated to the minimum extent necessary so that these Terms shall otherwise remain in full force and effect.
These Terms, together with the Privacy Policy, constitute the entire agreement between you and Helmwise regarding the use of the Service and supersede all prior agreements and understandings.

REMEMBER: Helmwise is a supplementary planning tool. Always rely on your own seamanship, official charts and publications, certified instruments, and professional judgment. The safety of your vessel, crew, and passengers is your responsibility alone.
