Companies change their terms without announcing it. We capture governance documents, compare each new version with the last, and publish what changed, with the source text behind it. One email a week on what we found and what we could not reach.
This page describes what the document states, permits, or reserves. It does not constitute a legal determination about enforceability. Regulatory applicability may vary by jurisdiction. Methodology
“all data, information, and materials generated from your access and use of the educational activities made available on or through the Service...shall be exclusively owned by Duolingo, and you shall not have any right to use such Activity Materials except as expressly authorized...”
“All payments are nonrefundable and there are no refunds or credits for Virtual Items or partially used membership periods, unless otherwise required by the law in your jurisdiction.”
“you hereby grant to Duolingo a full-paid, royalty free, perpetual, irrevocable, worldwide, nonexclusive, transferable, and sublicensable license to use, reproduce, copy, adapt, modify, merge, distribute, publicly display, and create derivative works from the Content...”
“You acknowledge that this license cannot be terminated by you once your Content is submitted to the Service.”
“Duolingo may amend, update, or change these Terms and Conditions. If we do this, we will post a notice...for at least 7 days after the changes are posted...”
“If you redeem a Promotion Code from a Code Provider, you understand and agree that Duolingo may share data relating to your use of the Promotion Code with your Code Provider, including both anonymized, aggregate data, and individual usage data.”
Duolingo's Terms set out the rules for using its service, including what you own (very little — Duolingo owns data and materials from your use, and keeps a permanent license to anything you submit). All payments are nonrefundable unless your local law says otherwise, and your subscription renews automatically unless you cancel. If you have a dispute with Duolingo, you must resolve it through individual arbitration rather than a lawsuit or class action.
Duolingo's Terms of Service establish the contractual relationship between Duolingo and its users, defining ownership, licensing, liability, and dispute resolution. Duolingo exclusively owns all data and materials generated through users' engagement with its educational activities, and users grant Duolingo a perpetual, irrevocable, worldwide, transferable, and sublicensable license over any Content they submit, with no right to terminate that license. Duolingo excludes all indirect, incidental, special, consequential, and exemplary damages and caps its total liability at amounts paid by the user in the 12 months prior to the claim. Disputes are subject to mandatory individual arbitration under AAA rules, with class and collective arbitration prohibited except as permitted by AAA's Supplementary Rules for Multiple Case Filings. Duolingo retains unilateral authority to amend these Terms, subject only to a minimum 7-day posted notice requirement.
Using Duolingo means that any Content you submit is licensed to Duolingo permanently and irrevocably — you cannot take that license back. Duolingo owns all data and materials generated from your use of its educational activities. Payments, including for Virtual Items and partial subscription periods, are nonrefundable under the Terms, though local consumer protection law in your jurisdiction may provide a remedy. Your subscription renews automatically each period until you actively terminate it. If you have a dispute, you must bring it as an individual arbitration claim rather than joining a class action. Users who redeemed a Promotion Code can expect that individual usage data may be shared with the provider of that code. To avoid automatic renewal charges, you must cancel your subscription before the next renewal period begins.
