How to get your money back, and what happens to your licence.

Refund Policy

Last updated: DATA — A PREENCHER

Short version: within 14 days of your purchase, write to us and we refund you, without asking why.

Why there is a trial and a refund window

Muster runs for 14 days without payment and without a card, with everything enabled. We would rather you decide before paying than after.

But a trial does not cover everything — you may have bought it for a machine that turned out not to suit it, or paid and then changed your mind. So the refund window exists as well, and it does not require you to have a reason.

How to ask

Either of these works:

• Reply to the receipt FastSpring sent you, or use the link on it.
• Or write to E-MAIL DE SUPORTE — A PREENCHER with the email address you bought with.

We process it within two business days. The money goes back by the same means you paid, and how long it takes to appear is up to your bank or card issuer — typically 5 to 10 business days.

What happens to your licence

A refunded licence is revoked. The app stops activating on new machines and, on the next revalidation, stops on the ones where it is installed.

If you are in the middle of something, nothing you made is deleted: your code is yours and it never left your machine, your agent sessions belong to the CLI, and both stay where they are.

Renewals

Muster renews once a year, and we tell you before charging.

If a renewal is charged and you no longer want it, write to us within 14 days of the charge and we refund it in full. Cancelling the renewal beforehand is simpler for both of us — you can do it from the FastSpring receipt at any time — and cancelling does not stop the app working: the last version you downloaded keeps working, indefinitely. What stops is the right to updates.

Your right of withdrawal in Brazil

If you bought as a consumer in Brazil, article 49 of the Consumer Protection Code gives you seven days from the purchase to withdraw, with a full refund, because you bought away from a physical shop.

That right is yours regardless of this page. Our 14 days are in addition to it, not instead of it.

After the window

We are not rigid about it. If something went wrong — the app did not work on your machine, a renewal took you by surprise, a purchase was made by someone else in your team — write to us and say what happened. We would rather refund a fair case than win an argument.

Before you call your bank

If you are about to open a dispute with your card issuer, write to us first. It is faster: a chargeback takes weeks and ends with the same money back that we can send you in two days.

Should you open one anyway, we will not contest a genuine case.
