Refund Policy
EFFECTIVE 18 FEBRUARY 2026
This page sets out how subscriptions, purchases, refunds, and hardware warranty work for MustDuo. It reproduces Sections 5, 6, 11, 16, and 17 of our Terms and Conditions, which govern in the event of any difference between this page and those Terms.
Subscriptions and digital purchases
The app operates on a freemium model with optional paid subscriptions and in-app purchases. Subscriptions and digital purchases are non-refundable except where required by law. To cancel a subscription, contact support@mustduo.com.
Platform-specific purchases (e.g., Apple App Store, Google Play) must be handled through the respective app store’s refund process.
In-app purchases
In-app purchases are non-refundable and managed via the app store. If an in-app purchase fails or is defective, contact support@mustduo.com, and we may provide a replacement or refund at our discretion.
Free trials
Free trials may be offered at our discretion. You may be required to provide billing information, and your subscription will auto-renew unless canceled before the trial ends.
Hardware refunds and replacements
Hardware purchases are refundable or replaceable within 30 days if defective. To request a refund or replacement, contact support@mustduo.com with proof of purchase.
You are responsible for return shipping costs unless the defect is manufacturer related.
EU and UK customers additionally have a statutory right to withdraw from a hardware purchase within 14 days of delivery, without giving a reason. To use this right, contact support@mustduo.com within 14 days of delivery. Return shipping is at your cost unless the item is defective.
Hardware warranty
You own the MustDuo tracker upon purchase, unless provided under a lease or promotional agreement (details specified at purchase). We offer a limited 1-year warranty covering defects in materials and workmanship. This does not include damage caused by misuse, modification, or accidents. To make a claim, contact support@mustduo.com with proof of purchase.
Suspended or terminated accounts
Misuse of the Service may result in suspension or termination without refund. Terminated users are not entitled to refunds.
