Cancellation Duet: Easy Method
What is Duet
Duet is a software solution that lets you use another device (for example a tablet or phone) as an external display for a computer or to add touch capability. It is offered as an app and subscription service across multiple platforms with both one‑time purchase and subscription models historically available.
The service is managed through Duet’s website and through platform stores (Apple App Store, Google Play). Billing and cancellation rules depend on where you subscribed and how you paid.
How to cancel Duet
- Web (Duet Account Management) - Sign in at Duet’s account page (visit duetdisplay.com), open the Profile tab, choose Manage Subscription, then Cancel Subscription. Closing the browser or signing out does not cancel. A confirmation notification is sent after cancellation; if you don’t receive it or you have issues, contact team@duetdisplay.com.
- iOS (App Store) - Subscriptions bought through Apple must be managed in your Apple subscription settings on the device (App Store / Settings → Subscriptions). Use Apple’s subscription controls to cancel.
- Android (Google Play) - Open the Google Play app, go to Subscriptions, select the Duet subscription and tap Cancel subscription. Uninstalling the app does not cancel the subscription.
- PayPal / Duet “My Account” payments - If you paid via PayPal through a Duet partner, cancel in two places: cancel inside Duet’s My Account AND cancel the associated automatic payment in your PayPal account (Billing Agreements / Automatic Payments) to stop future charges.
What happens when you cancel
After cancellation you generally retain access until the end of your current paid period; cancellation prevents the subscription from renewing. If you cancel during a free trial before it converts, you should not be billed at the end of the trial.
Duet typically sends a confirmation notification after a successful cancellation. Your account, settings and any locally installed app remain on your devices but future recurring billing should stop. If you used a third‑party platform (Apple, Google, PayPal), the platform controls billing and any remaining access period.
Will I get a refund?
Duet’s stated policy is that there are no refunds or credits for partial months, unused time, or upgrades/downgrades; refunds are only issued for duplicated payments or other cases approved by Duet billing. If you cancel during a trial period (where applicable), cancellation generally prevents billing at the trial end.
If you were charged through Apple or Google, refund requests are generally handled through their respective refund processes (Apple Support or Google Play support). If charges continue after you cancelled, you may be able to dispute the charge with your bank or request a refund through the platform that processed the payment.
Duet plans and pricing
| Plan | Price | Period | Features |
|---|---|---|---|
| Duet Display (sale example) | C$10.99 | One-time purchase (sale, 2016) | Standard Duet Display functionality |
| Duet Display (sale example) | C$8.99 | One-time purchase (sale, 2015) | Standard Duet Display functionality |
Your consumer rights in Canada
Canadian consumer protection requires that cancellation processes be clear and functional. If a free trial cannot be cancelled or the cancellation method is opaque, that may raise concerns under provincial and federal consumer protection laws. There is no single nationwide “right of withdrawal” for all digital content, but provinces enforce fair business practices and disclosure rules; deceptive or difficult cancellation processes may be actionable.
If charges continue after cancellation, you have several options in Canada: request a refund from the merchant (Duet), request a refund from the platform that charged you (Apple or Google), or file a dispute/chargeback with your bank or card issuer. For subscriptions billed via PayPal, you can also cancel the automatic payment in PayPal and raise disputes there. If you believe your consumer rights have been breached, you may contact your provincial consumer protection office for guidance.
Customer experiences
User feedback is mixed. Many users praise Duet as a strong, affordable alternative for external displays and note good technical support experiences where Duet support responded quickly to installation or technical issues.
At the same time, complaints exist about billing and cancellation: some users report difficulty cancelling free trials, unexpected charges after deleting the app, or continued billing after they thought they had cancelled. There are reports where support described charges as “finalized” and declined refunds; these experiences highlight the importance of confirming cancellation and checking billing statements.
Documentation checklist
- Account email and username used with Duet
- Order receipt or subscription confirmation (email or app store receipt)
- Subscription ID (if provided) or transaction ID from Apple/Google/PayPal
- Screenshots showing your subscription settings and any cancellation attempts or error messages
- Confirmation email of cancellation (if received) or a record of the absence of one
- Bank/credit card or PayPal statement showing the charge(s) in question
Common mistakes
Users often assume deleting the app or signing out will cancel a subscription - it will not. Subscriptions must be cancelled through the account management flow where they were purchased (Duet website, Apple, Google, or PayPal). Another common error is cancelling only in Duet when payment was set up with PayPal (or vice versa); both places must be addressed. People also expect prorated refunds for unused time despite Duet’s stated no‑refund policy; check the policy before assuming a refund will be issued.
Comparative recap
| Method | Refund | Difficulty |
|---|---|---|
| Web (Duet Account Management) | Generally no (exceptions for duplicates or billing‑approved refunds) | Easy - preferred, immediate cancellation and confirmation |
| iOS (App Store) | Possible via Apple refund processes; subject to Apple’s review | Medium - manage via Apple subscription settings |
| Android (Google Play) | Possible via Google Play refund processes; subject to Google’s review | Medium - manage via Google Play subscriptions |
| PayPal (Duet partner payments) | Generally no via Duet policy; you must also cancel automatic payments in PayPal; refunds only if approved | Medium - High - cancel in both Duet and PayPal to stop future billing |
After cancelling
After you cancel, look for a cancellation confirmation from Duet and verify that no further charges appear on your bank, card or PayPal statements. If you were billed through Apple or Google, use their refund request workflows if you need a refund. If charges continue despite cancellation, contact Duet at team@duetdisplay.com, then your payment provider (Apple Support, Google Play support or your bank) to dispute the charge.
