RAP DUO
Terms of Service
How Rap Duo works, your responsibilities, and the terms for credits and subscriptions.
Updated October 25, 2026
Who operates Rap Duo
RapDuo at rapduo.io is operated by Wang Xiaochun, an individual operator in Hong Kong. Contact support@rapduo.io for questions about these terms.
The service
RapDuo provides AI music and lyric generation, short photo-based videos, song performance videos and music gifts. Available models, duration, format and credit cost are shown before submission. Some audio tools run locally in your browser. AI results can vary in words, pronunciation, likeness, movement and synchronization. We do not promise an exact lyric, an existing song, a celebrity likeness or an artist voice.
Your account and permission to use photos
You must be at least 18 to purchase and use this service. Keep your account secure and provide accurate information. Upload only photos that you own or have permission to use, including consent from the people pictured. Do not upload intimate, exploitative, unlawful or deceptive material, or use the service to harass, defraud or impersonate someone. We may reject requests that violate these rules.
Optional song performance MVs
OmniHuman 2.0 creates a continuous character performance from one adult character image and your selected, already reviewed song. You may select 4 to 300 seconds, subject to model availability. The MV planner proposes creative direction from lyrics and song details, without measured word timings. Results can vary in identity, movement, camera response and synchronization; exact scene cuts or lyric-by-lyric actions are not guaranteed. Confirm the current video credit cost before generation. Existing songs, playback and downloads are not charged again. Optional AI character images have their own displayed image-generation price.
Credits and payment
The price, number of credits, currency and any applicable taxes are shown before payment. One standard 720p, 15-second generation reserves 45 credits. Credits are spent when a conforming video has been stored for your account. A confirmed generation failure returns the reserved credits. An uncertain provider status is investigated before the reservation is released or spent. Credits have no cash value and cannot be transferred to another account.
Credit packs and subscriptions
Credit packs are one-time purchases whose credits do not expire. Monthly subscriptions renew monthly; each allowance expires at the end of its paid month. Yearly subscriptions charge the full annual amount and grant the full annual allowance upfront; that allowance expires at the end of the paid year. Unused subscription credits do not roll over. Only one paid or pending subscription can be held per account across Stripe and PayPal.
Cancellation and refunds
You can cancel future renewals in Billing. Cancellation does not remove credits already paid for; they remain available until their original expiry. Plan changes take effect through a new purchase after the current paid subscription ends. Credit packs can be added in the meantime. See the separate Refund Policy for cash refunds.
Video effects and gift cards
Video effects use one or two authorized photos and a creative AI template; results may vary. Gift cards reserve the sender’s credits immediately and bind to one recipient account when claimed. Each successful gift video spends a whole selected opportunity, even if the recipient chooses a shorter duration, lower model or lower resolution. Failed generations restore an opportunity while the card is active; unused opportunities can be recalled. Subscription-funded gifts cannot outlive their original credits. The recipient owns access to their private photos and videos; the sender can see usage counts only.
Your content and downloads
You retain your rights in the photos, audio, lyrics and other material you provide. Upload or submit only content you have permission to use and share, including permission from people pictured. You permit us and our service providers to process it as needed for your requested service, safety, fraud prevention and support. We do not automatically publish your work to a public gallery. A gift link you explicitly create lets anyone with that link see its selected message and cover, and play or download its selected songs until it expires or you revoke it. AI output may not be unique or eligible for copyright protection; payment does not guarantee exclusive copyright.
Storage and availability
Download the results you want to keep before their displayed expiry. Source portraits in our application storage expire after 7 days; stored songs, cover images and finished videos normally expire after 30 days. Shared gifts cannot extend the original files' availability. Task, account, payment and dispute records have separate retention purposes. Exceptional retention may be needed for a legal obligation or a specific abuse or payment dispute. Generation time depends on the upstream provider; uninterrupted access and a particular creative result are not guaranteed.
Copyright and content complaints
To report a copyright, privacy, likeness or other content concern, email support@rapduo.io. Identify the work or person concerned, the RapDuo page or task needed to locate it, your connection to the rights involved and a way to contact you. We assess reports, may restrict access while reviewing them, and may ask the uploader to respond. We may restrict accounts that repeatedly infringe others' rights. Contact support if you believe a restriction was made in error.
Questions and changes
For billing, access, content or privacy questions, contact support with your account email and order or video reference. Do not send passwords or card details. Updates to these terms will be posted here. Nothing in these terms removes mandatory rights that apply to you.
