Latest stance: sublicensable or transferable

Subject to the terms of these Terms and Conditions, Duolingo grants you a non-transferable, non-exclusive license to download, install, and use one copy of each App in object code form only on an interactive wireless device that you own or control. You may not derive or attempt to derive the source code of all or any portion of any App, permit any third party to derive or attempt to derive such source code, or reverse engineer, decompile, disassemble, or translate any App or any part thereof. Duolingo and its licensors own and shall retain all intellectual property rights and other rights in and to the Apps, and any changes, modifications, or corrections thereto. The following terms and conditions apply to you only if you are using the Apps from the Apple App Store. To the extent the other terms and conditions of these Terms and Conditions are less restrictive than, or otherwise conflict with, the terms and conditions of this paragraph, the more restrictive or conflicting terms and conditions in this paragraph apply, but solely with respect to Apps from the Apple App Store. You acknowledge and agree that these Terms and Conditions are solely between you and Duolingo, not Apple, and that Apple has no responsibility for the Apps or content thereof. Your use of any App must comply with the App Store Terms of Service. You acknowledge that Apple has no obligation whatsoever to furnish any maintenance and support services with respect to the Apps.
