This page explains how billing, trials, cancellation, and refunds work for The Muster App and Muster Mate. It forms part of our Terms of Service.
Every new account includes a 14-day free trial with full access to all features. No payment information is required to start the trial. The trial is your opportunity to evaluate the Service in full and decide whether it is right for your vessel before any payment is taken. If you decide not to continue, simply do not subscribe — there is nothing to pay and nothing to refund.
Paid subscriptions are billed annually in advance. Once a subscription payment has been taken, it is final and non-refundable. Because the free trial lets you assess the Service before paying, we do not operate a money-back guarantee and we do not offer prorated or partial-year refunds for unused time after a subscription begins.
You may cancel your subscription at any time to stop future renewals. When you cancel:
If you believe you have been charged in error — for example a duplicate charge or an incorrect amount — contact us at support@themusterapp.com and we will investigate and correct any genuine billing error promptly.
If you would like us to consider a refund in your particular circumstances, you are welcome to email support@themusterapp.com and explain your situation. Any refund outside of a billing error is granted entirely at our sole discretion, considered case by case. A discretionary refund is not a right or a guarantee, and we may decline a request. Where a refund is approved, it is typically processed within 5–10 business days.
Nothing in this policy removes or limits any non-excludable statutory or consumer rights you may have under applicable law, including any cancellation rights that apply to you. This policy applies in addition to those rights.
We do not automatically delete your data when a subscription ends, so you can resubscribe and continue where you left off. You may ask us to export or delete your data at any time, and we will erase it on request, subject to any records we are required to keep by law. The one exception is muster audio recordings, where enabled, which are automatically deleted after the retention period configured by your vessel. For more detail, see our Privacy Policy.
