Terms of Service
Last updated: 28 August 2026
What you are getting
Duobot is a browser extension that automates Duolingo lessons. A subscription unlocks the automation for as long as it is active.
Your responsibility
Duolingo's own terms govern your use of Duolingo. Automating lessons may conflict with those terms, and your Duolingo account is yours to risk. We do not control Duolingo and cannot protect an account from action taken by them. If that risk is not acceptable to you, do not use Duobot.
Billing
Subscriptions renew automatically until cancelled. Cancel any time and access continues to the end of the period already paid for. Prices are shown before you pay and may change with notice, never retroactively for a period already billed.
Refunds
Write to support@appduobot.com within 14 days of a charge and we will refund it.
Acceptable use
One subscription is for one person. Do not resell access, share credentials, or redistribute the extension. Do not use Duobot to break the law.
Availability
Duolingo changes its site often, and a change on their side can stop parts of Duobot from working until it is updated. We fix breakages as quickly as we can but cannot promise uninterrupted service. Duobot is provided as is, without warranty, and our liability is limited to the amount you paid in the previous twelve months.
Ending it
You can stop at any time by cancelling and removing the extension. We may end an account that breaks these terms, with a refund of any unused period.
