1. Your Rights in and Warranties for User Content
You retain intellectual-property and other rights you lawfully hold in User Content. You confirm and warrant that you own the rights in the User Content or have obtained the lawful rights needed to upload, edit, dub, add music, translate, adapt, publish, disseminate, and authorize our use of it; and that the User Content does not infringe any third-party rights.
Before using another person's works, film or television clips, music, images, subtitles, trademarks, portraits, or personal information, you must obtain required authorization and retain and provide proof when required by law or the right holder. Labeling content "derivative creation" or "personal opinion," or identifying a source, does not by itself remove the obligation to obtain authorization or bear liability.
2. Authorization Needed to Provide the Service
To store, review, transcode, generate subtitles for, translate, recommend, distribute, play, display, share, back up, and maintain User Content you submit, you grant us a non-exclusive, worldwide, royalty-free license within the scope necessary to provide and improve the Service. To complete the relevant technical processing, we may allow necessary service providers bound by us to process User Content within their entrusted scope, without transferring ownership of the content.
This license is limited to:
providing and displaying content to users according to your visibility settings;
enabling search, recommendations, subtitles, translation, content safety, sharing cards, and playback adaptation;
introducing and promoting LingoFly and your public content reasonably on LingoFly-owned pages, app-store pages, or official accounts; and
handling complaints, infringement notices, content governance, disputes, backups, and statutory obligations.
Unless otherwise required by law or separately authorized by you, we will not sell your User Content, use your non-public content for off-platform marketing, or allow third parties to independently operate your content apart from LingoFly. We will separately obtain your authorization before using your likeness, voice, or works in independent advertising, commercial endorsements, general-model training, or commercial purposes beyond what is necessary to provide and improve the Service.
3. Authorization Term and Termination
When you delete content, make it visible only to yourself, or cancel your Account, the corresponding authorization for public display ends according to actual functionality and legal requirements, except where:
the content has been lawfully shared by other users and is beyond our control;
restricted retention for a limited period is necessary for backup recovery, security, complaints, infringement, disputes, or statutory obligations, and the content is no longer used for public display, recommendation, or marketing;
you separately and affirmatively choose to retain public content in the account-cancellation process, and rules in the applicable region and app store permit continued display; or
you and we have separately entered into a lawful and effective creator or commercial authorization agreement.
Before cancelling your Account, you may first delete content that you do not wish to remain public. You may contact us to request deletion of content that must be deleted by law or whose continued public display would unreasonably harm your rights.
4. Content Labels
When publishing, you may choose labels such as "no label needed," "contains a real person on screen," "AI-generated content," "contains virtual items," "derivative creation," or "personal opinion." Except for "no label needed," the selected label will be prominently displayed in the playback layer or content page as an "Author Declaration."
When you use AI technology to generate, synthesize, or materially alter text, images, audio, video, or virtual scenes, you must truthfully select the appropriate label and retain existing generated/synthetic identifiers in the file. You must not maliciously delete, tamper with, forge, or conceal explicit labels, implicit identifiers in file metadata, or dissemination identifiers we add.
For content legally required to be labeled, we may add a clearly identifiable explicit notice, such as "AI-generated content" or "suspected AI-generated content," around the content based on file metadata, your declaration, and necessary technical detection, and record necessary generation or dissemination elements in file metadata under applicable rules. Specific placement and style are subject to applicable law, mandatory standards, and publishing-page instructions.
Where law requires prominent notices for AI-generated or synthesized content, content that may affect minors' physical or mental health, or other specific content, we may require supplemental or corrected labels. If you refuse to correct them, we may restrict publication or dissemination. Labels such as "AI-generated content," "derivative creation," or "personal opinion," or identifying a source, do not exempt you from responsibility for the legality, authenticity, and source of rights in your content.
