Legal
Terms of Service
Effective 29 September 2026
1. About these terms
These terms govern use of MusterDeck and its public website. By creating an account or using the service, you agree to use MusterDeck only for lawful maritime business purposes and in accordance with your organisation's authority and policies.
2. Operational responsibility
MusterDeck is a software support platform. It does not replace the Master, owner, operator, company Safety Management System, applicable legislation, flag-State requirements, class rules or professional judgement. Users remain responsible for checking records, schedules, drills, reports and decisions against the requirements that apply to their vessel and operation.
3. Accounts and access
You are responsible for keeping account credentials secure and for ensuring each user has an appropriate role. Access must not be shared with unauthorised persons. MusterDeck may suspend access where there is a credible security, misuse or payment concern.
4. Customer data
You retain responsibility for the accuracy and lawful use of information entered into MusterDeck. The service is designed to separate company and vessel records according to authorised access. You must not upload information you are not entitled to process or share.
5. Availability and offline use
Some MusterDeck workflows can operate with intermittent connectivity, while management, reporting, sharing, payment and other functions may require an internet connection. Offline records are subject to synchronisation and permission checks when connectivity returns.
6. Subscriptions and billing
Paid access is provided according to the selected plan, vessel and user allowances, billing period and any agreed add-ons. Subscription details shown at checkout or on an agreed invoice form part of these terms. Cancellation takes effect in accordance with the billing terms shown for the subscription.
7. Acceptable use
You must not attempt to bypass access controls, probe another customer's data, interfere with the service, introduce malicious code, misuse shared links or use MusterDeck to create misleading or fraudulent compliance records.
8. Intellectual property
MusterDeck, its software, branding, templates and platform content remain the property of their respective owners. Customer-created operational records remain customer data, subject to the rights needed for MusterDeck to host, process, secure and deliver the service.
9. Service changes
MusterDeck may improve, replace or retire features as the platform develops. Material changes that significantly affect paid service will be communicated where reasonably practicable.
10. Liability and safety
MusterDeck is not a substitute for statutory compliance checks or safe operational decision-making. Nothing in the platform transfers the legal or operational responsibilities of owners, operators, Masters, officers, crew, designated persons, surveyors or other responsible parties.
11. Wellbeing and mental-health information
The MusterDeck Wellbeing Hub provides general maritime wellbeing awareness and signposting only. It is not a healthcare provider, counselling service, emergency service, medical device or substitute for a doctor, psychologist, psychiatrist, occupational-health professional, telemedical service or other suitably qualified professional. MusterDeck does not diagnose mental-health conditions, assess fitness for duty, provide treatment, make clinical decisions or guarantee that any information is suitable for an individual person's circumstances. In an emergency or where there is an immediate risk to safety, users must follow the applicable vessel, company, medical and emergency procedures and seek appropriate professional or emergency assistance without relying on MusterDeck.
12. Wellbeing privacy and sensitive information
The Wellbeing Hub is designed as an awareness resource and is not intended to collect individual mood scores, diagnoses, counselling notes, self-harm disclosures or mental-fitness assessments. Viewing, not viewing or using wellbeing content must not be treated as evidence of a mental-health condition, fitness for duty, performance issue or other employment characteristic. Users should not place sensitive health information into general free-text fields unless their organisation has specifically authorised that processing and has an appropriate lawful basis, special-category condition, privacy notice, access controls and retention arrangements. Employers and operators remain responsible for their own employment, data-protection, confidentiality, occupational-health and safeguarding obligations.
13. External support services
MusterDeck may link to independent welfare, charity, medical, emergency or professional-support services. Those services are not operated or controlled by MusterDeck. Availability, eligibility, telephone numbers, response times and content can change. Users should verify current information on the provider's official service and use the service appropriate to their location and circumstances. A link does not create a clinical relationship with MusterDeck or amount to an endorsement of every service offered by the third party.
14. Privacy
Personal information is handled in accordance with the MusterDeck Privacy Notice. Where your organisation uses MusterDeck to process crew or employee information, your organisation is responsible for having an appropriate lawful basis and providing required notices.
15. Contact
Questions about these terms, subscriptions or use of the service can be submitted through the MusterDeck contact page.
