Terms of Service

Effective date: 16 July 2026

Last updated: 31 October 2026

Version: 0.5

These Terms of Service ("Terms") govern your access to and use of the PassageMaster™ application, website at passagemaster.app, and related services (together, the "Service"), operated by Astramara, LLC ("Astramara", "we", "us", or "our").

You accept these Terms only by an affirmative clickwrap action in the Service: checking the required boxes and clicking I Agree on the first-entry acceptance screen, and on any later re-acceptance screen after a material change. We record that assent, including the versions of these Terms and the related documents you accepted. Browsing the website, creating or receiving an account, or signing in does not, by itself, constitute acceptance of these Terms.

If you do not agree, do not click I Agree and do not use the Service. The Emergency quick-reference remains available if you decline.

PassageMaster™ is a decision-support cruising companion. It does not replace official charts, certified navigation equipment, prudent seamanship, or the judgment of a vessel's captain. Please read the Disclaimers carefully; they are part of these Terms.

1. Who may use the Service

You may use the Service only if you can form a binding contract with Astramara and are not barred from doing so under applicable law. You must be at least 18 years old, or the age of majority in your jurisdiction if higher. If you use the Service on behalf of an organization, you represent that you are authorized to accept these Terms for that organization.

2. The Service

PassageMaster™ provides planning, situational-awareness, and vessel-understanding features, which may include satellite map context, imported passages, region information packs, environmental information (weather, tides, currents), vessel data display through Signal K or device GPS, an optional captain-opt-in Share location session, structured speech interaction, and the Quartermaster AI assistant. Features vary by plan, region, device, and connectivity, and may change, be added, or be removed over time.

Share location is not limited to family. New sessions are password-gated. People who have the link and the password can view share-safe position geometry until you revoke access or the session expires. You choose 14, 30, or 60 days when you create the session. The default is 30 days. The password is not placed in the link or in email. Older sessions created without a password remain reachable by the link until you set a password or revoke them. Share location is not a distress beacon, not a filing with any rescue authority, and not a substitute for EPIRB, PLB, VHF, DSC, a rescue coordination center, or U.S. Coast Guard procedures.

The Service does not weather-route and does not produce a recommended track. A captain may import a passage and may import a captain-supplied GRIB file to check a line. Composing a GRIB request hands the message to the device email program. PassageMaster™ does not send that email and does not store the GRIB file on our servers. Membership-gated Passage Weather packs are decision-support along a downloaded corridor. They are not an official marine forecast.

The man-overboard crew card is decision-support. It is not a certified search-and-rescue procedure. It does not appoint a person in command. PassageMaster™ does not transmit the call. The accepted wording is in the Disclaimers. Quartermaster on that card speaks only that accepted wording.

Text messages. PassageMaster™ may send boat-event text messages to a mobile number you opt in. Message frequency varies. Message and data rates may apply. Reply STOP to opt out. Reply HELP for help. Read the Privacy Policy and these Terms of Service. You can also email legal@passagemaster.com. These messages are decision-support. They are not a certified alarm, and they do not command the boat.

The Service made available today is a progressive web app. It is not offered in the Apple App Store or on Google Play. Chart imagery is not a certified ENC and is not official carriage.

The Service is not a certified navigation system, does not provide commercial-grade collision avoidance, and does not offer autonomous vessel control. You remain solely responsible for the safe operation of your vessel.

3. Accounts

Some features require an account. Account sign-in is provided through our identity provider. You are responsible for maintaining the confidentiality of your credentials and for all activity under your account. Notify us promptly of any unauthorized use. We may suspend or terminate accounts as described in Section 12.

4. License to use the Service

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Service for your personal or internal business cruising purposes. Software components installed on your device are additionally governed by the End User License Agreement.

5. Subscriptions, billing, and refunds

Paid features are offered on a subscription basis. Pricing, renewal, cancellation, and refund terms are described in the Subscription and Refund Policy, which is incorporated into these Terms. Payments are processed by our third-party payment processor; we do not store full payment card numbers.

6. Acceptable use

Your use of the Service must comply with the Acceptable Use Policy. In particular, you must not rely on the Service as a sole or primary means of navigation, and you must not misuse, disrupt, reverse engineer, or attempt to gain unauthorized access to the Service.

7. Your content and data

You retain ownership of content and data you provide (for example, imported routes, boat profile details, and notes). You grant us a limited license to host, process, and display that content solely to operate and improve the Service for you. Our handling of personal data is described in the Privacy Policy. If you submit community or user-generated content where such features are offered, the Community Content Terms also apply.

8. Third-party data and services

The Service incorporates data and services from third parties (for example, map imagery, weather, tide, chart, and survey sources). Their content is subject to the Third-Party Data Attribution notice and to the third parties' own terms. We do not guarantee the accuracy, completeness, availability, or timeliness of third-party data. Open-source components are listed in the Open-Source Notices.

9. Intellectual property

The Service, including its software, design, text, graphics, and the names "PassageMaster™", "Quartermaster", and "Astramara", is owned by Astramara or its licensors and protected by intellectual-property laws. See the Copyright Notice. Except for the rights expressly granted to you, no rights are transferred.

10. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT. The navigation, marine-safety, AI, and data-accuracy disclaimers in the Disclaimers document form part of these Terms. Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you.

11. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, ASTRAMARA AND ITS SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, DATA, GOODWILL, OR FOR PERSONAL INJURY OR PROPERTY DAMAGE, ARISING OUT OF OR RELATED TO YOUR USE OF OR INABILITY TO USE THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, ASTRAMARA'S TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE LIABILITY, OR (B) USD 100.

Nothing in these Terms limits liability that cannot be limited under applicable law (for example, liability for death or personal injury caused by negligence where such limitation is prohibited, or for fraud). Where such laws apply, this section is limited to the fullest extent permitted.

12. Suspension and termination

You may stop using the Service at any time. We may suspend or terminate your access if you breach these Terms, if required by law, or to protect the Service or other users. On termination, the license in Section 4 ends. Sections that by their nature should survive (including Sections 7–11 and 13–16) will survive termination.

13. Changes to the Service and these Terms

We may modify the Service or these Terms. If we make material changes to these Terms, we will provide reasonable notice (for example, in-app or by email) and ask you to accept the updated Terms by a new I Agree action before continued product use. We will record that re-acceptance. Continued use alone is not acceptance of a material change. If you do not agree, you must stop using the Service (the Emergency quick-reference remains available).

14. Electronic signatures and records (E-SIGN / UETA)

You agree that clicking I Agree (after checking the required boxes) is a legally binding electronic signature under the U.S. Electronic Signatures in Global and National Commerce Act (E-SIGN) and the Uniform Electronic Transactions Act (UETA), including Florida's UETA, Fla. Stat. § 668.50.

You consent to receive these Terms, related legal documents, and notices as electronic records. A paper copy of the current documents is available on request by emailing legal@passagemaster.com.

15. Governing law and disputes

These Terms are governed by the laws of the State of Florida, USA, without regard to conflict-of-laws rules, and are formed as an electronic contract under Fla. Stat. § 668.50 (UETA). The exclusive venue for disputes is the state or federal courts located in Florida. These Terms do not include a binding arbitration clause or class-action waiver unless those terms are later adopted in an updated version. Nothing in this section deprives a consumer of the protection of mandatory laws of their country of residence.

16. General

These Terms, together with the documents incorporated by reference, are the entire agreement between you and Astramara regarding the Service. If any provision is held unenforceable, the remaining provisions remain in effect. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets.
