Help with your subscription. Written down, so you do not have to ask.
Mustro sells through three tills: the App Store, Google Play, and the web. Cancelling, restoring, and refunding work differently at each one, so every article below says which till it applies to.
Write to support
A person reads every note and answers, usually within one business day. Include the email on your account and, for a billing question, the receipt or order number.

Billing, answered.
Every article names the till it applies to. If you are not sure which one is charging you, start with the first article.
Cancel your subscription
Where cancellation actually happens for an App Store, Google Play, or web subscription, and what you keep until the period ends.
Restore a purchase
How to get a store subscription back after a reinstall or on a new device, and what to do when restore finds nothing.
Refunds
Who grants a refund for each till, how to ask, and what a refund does to your plan and your data.
When your plan lapses
What read-only means, what keeps working, what stops, and why we do not publish a grace period of our own.
Switch how you pay
How to move between App Store, Google Play, and web billing without paying for the same plan twice.
Who took your money decides what you can do.
Mustro is the same product whoever sold it to you. What changes is where the subscription lives, and therefore who can cancel or refund it.
App Store
Bought inside the iPhone app. Apple bills you and Apple cancels.
Google Play
Bought inside the Android app. Google bills you and Google cancels.
Web
Bought on the web. We bill you, and we can cancel or refund it.
Not sure which one you are on? Open the Mustro app, go to You, then Subscription. The manage link there points at the till that holds it.
Still stuck?
Tell us what happened and what you expected instead. We answer every note, and we would rather hear about a charge you did not expect than have you wait on it.
