Terms of Service

Last Updated: April 2026

These Terms of Service ("Terms") govern your use of the Muster application and related services (the "Service") operated by The Muster App Ltd ("we", "us", or "our"). By using the Service, you agree to these Terms.

1. Description of Service

The Muster App is a maritime safety and crew management application designed for use on vessels. The Service provides tools for visitor check-in/out, crew management, muster drills, safety document management, and related vessel safety operations.

2. Account and Access

Access to the Service requires authorization by a vessel administrator. Each device must be registered and approved using a vessel-specific access code. You are responsible for:

Maintaining the confidentiality of your access credentials
All activities that occur under your account or device
Notifying us immediately of any unauthorized use of your account

3. Acceptable Use

You agree not to:

Use the Service for any unlawful purpose or in violation of these Terms
Attempt to gain unauthorized access to any part of the Service
Interfere with or disrupt the Service or servers connected to the Service
Reverse engineer, decompile, or disassemble any part of the Service
Use the Service to collect or store personal data about others except as intended by the Service's features
Share access codes or credentials with unauthorized parties

4. Data and Content

You retain ownership of all data you submit to the Service, including visitor records, crew information, safety documents, and photographs. By using the Service, you grant us a limited license to process and store this data solely for the purpose of providing the Service.

You are responsible for:

The accuracy and legality of data you submit to the Service
Obtaining necessary consent from individuals whose data you collect using the Service
Complying with applicable data protection laws in your jurisdiction
Maintaining your own backups of critical data

5. Audio Recording Feature

The Service includes an optional audio recording feature for muster drill sessions.

Purpose: Audio recording is provided to support compliance with maritime safety regulations, including documentation of emergency drill procedures as required by the ISM Code and SOLAS Convention
Vessel Operator Responsibilities: If you enable audio recording, you are responsible for informing all persons present during a recorded muster session that recording is taking place, obtaining any consent required by applicable law, and complying with all applicable recording and privacy laws in your jurisdiction
Controls: Audio recording is disabled by default. Vessel administrators may enable or disable it at any time. Recordings can be deleted by the vessel administrator at any time
Restrictions: You must not use the audio recording feature for surveillance, to record private conversations without consent, or for any purpose other than documenting muster drill sessions

6. Optical Character Recognition (OCR)

The Service uses on-device optical character recognition technology to extract text from documents during visitor onboarding and vehicle checkout processes, including identification documents and driver's licences.

Best Effort: OCR is provided as a convenience to speed up data entry. While we strive for accuracy, optical character recognition is inherently limited by factors including image quality, lighting conditions, document condition, and text formatting. Results may be incomplete or inaccurate
Administrator Responsibility: Vessel administrators and operators are responsible for reviewing and verifying that any information captured via OCR is correct before relying on it. The Service retains the original captured image alongside any extracted text for verification purposes
Compliance: Administrators should ensure that the captured data meets their own compliance and record-keeping requirements. OCR output should not be treated as authoritative without manual verification
No Guarantee: We do not guarantee the accuracy, completeness, or reliability of any text extracted via OCR. The feature is provided "as is" and should be used as a supplementary tool, not a replacement for manual document review

7. Privacy

Your use of the Service is also governed by our Privacy Policy, which describes how we collect, use, and protect information. By using the Service, you consent to the practices described in the Privacy Policy.

8. Service Availability

We strive to maintain high availability of the Service but do not guarantee uninterrupted access. The Service may be temporarily unavailable due to maintenance, updates, or circumstances beyond our control.

Certain features of the Service rely on third-party data feeds and infrastructure. Where this is the case, availability and accuracy depend on those external providers and are outside our direct control. We provide such features on a best-effort basis only.

In particular, the Tender Tracker feature relies on vessel position data delivered by Peplink InControl 2 from Pepwave routers installed on the vessel and tenders. We do not own, operate, or control this hardware or telemetry service. Position data may be delayed, incomplete, inaccurate, or unavailable at any time, including but not limited to loss of cellular coverage, hardware power-down, the device being switched off, third-party API outages, or changes to Peplink's services. Tender Tracker is provided as a situational-awareness aid only and must not be relied upon for navigation, search and rescue, or any safety-critical decision.

Important: The Muster App is a supplementary safety tool. It does not replace mandatory safety equipment, procedures, or regulatory requirements. Vessel operators remain fully responsible for vessel safety and compliance with all applicable maritime regulations regardless of their use of the Service.

12. Limitation of Liability

To the maximum extent permitted by applicable law, The Muster App Ltd shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits or revenues, whether incurred directly or indirectly, or any loss of data, use, goodwill, or other intangible losses resulting from:

14. Termination

We may terminate or suspend your access to the Service immediately, without prior notice, for conduct that we believe violates these Terms or is harmful to other users of the Service, us, or third parties, or for any other reason at our sole discretion.

Upon termination, your right to use the Service will cease immediately. You may request a copy of your data within 30 days of termination.

15. Changes to Terms

We reserve the right to modify these Terms at any time. We will notify vessel operators of material changes by email or through the Service. Your continued use of the Service after changes become effective constitutes your acceptance of the revised Terms.

16. Governing Law

Severability: If any provision of these Terms is found to be unenforceable, the remaining provisions will continue in full force and effect
Waiver: Our failure to enforce any right or provision of these Terms will not be considered a waiver of those rights
Assignment: You may not assign or transfer these Terms without our prior written consent. We may assign our rights and obligations without restriction

Where the Service displays Marine Guidance Notices (MGN / MIN / MSN) issued by the Maritime and Coastguard Agency, or accident investigation reports published by the Marine Accident Investigation Branch, the original documents are served directly from the gov.uk website in an in-app browser and are subject to Crown copyright.
