Terms of Service

Last updated: November 1, 2026 · Version 2.0

These Terms of Service ("Terms") are an agreement between you and the operator of KUKU剪 ("we", "us") regarding access to and use of the kukucut.app website, the desktop client, and related services (the "Service").

Please read these Terms carefully before using the Service. By registering an account, purchasing credits, or using the Service, you confirm that you have read, understood, and agree to these Terms and the Privacy Policy. If you do not agree, please stop using the Service.

You confirm that you are at least 18 years old and have full legal capacity. If you use the Service on behalf of a company or other organization, you represent and warrant that you are authorized to do so.

1. The Service

KUKU剪 provides speech recognition, translation, Southeast Asian language voiceover, and video composition for Chinese spoken-word videos, as well as watermark-free parsing of short-video share links. You can upload audio, video, text, and other materials through the website and desktop client, and the Service generates subtitles, translations, voiceovers, and final videos. The desktop client uses the account you sign in with on the website, processes media in the cloud, and deducts credits from that account.

Features, credit consumption rates, supported languages, and input/output formats are those shown on the website and pricing page, and may change from time to time.
The Service uses artificial intelligence and third-party cloud services. Output may be inaccurate, incomplete, or unsuitable for your particular purpose. You should review accuracy, legality, and quality before publishing.
Free, test, or preview features are provided "as is" and may change, be rate-limited, or be discontinued.
We work to keep the Service available but do not guarantee that it will be uninterrupted, timely, or error-free.

2. Accounts

You must provide true, accurate, and complete registration information and keep it up to date.
You must verify your email address. Keep your password, API keys, and verification codes secure, and do not share your account or resell access.
You are responsible for all activity under your account. Notify us immediately of any unauthorized access or security incident.
To protect security or comply with legal obligations, we may require you to reset credentials, restrict features, or suspend your account.
You may delete your account at any time in account settings or by contacting us at the email below.

3. Credits, Pricing, and Payment

The Service uses prepaid credits. It does not offer subscriptions and does not auto-renew.
Credit package prices and the credit cost of each feature are those shown on the pricing page and at checkout. Prices are in RMB and include applicable taxes.
Paid services are sold through our payment provider. The payment provider acts as the merchant of record and is the legal seller of the paid service to you. It handles collection, invoicing, tax calculation and remittance, payment processing, refunds, and payment disputes; its terms of service and privacy policy also apply.
Credit types: credits purchased in a package are "purchased credits"; new-user grants and extra credits included with a package are "bonus credits". We deduct purchased credits before bonus credits.
New-user grant: after verifying your email, a new account may receive bonus credits, once per user. If you obtain bonus credits through bulk registration, alias emails, or similar methods, we may revoke the credits and restrict the account.
Validity and restrictions: credits do not expire, but they lapse when the account is deleted or terminated under Section 12. Credits may be used only in the Service and may not be transferred, withdrawn, or exchanged for cash.
Price changes: we may adjust package prices or credit consumption rates. Changes do not affect the number of credits you already hold; changes to consumption rates will be announced on the website in advance and apply only to tasks started after they take effect.
You authorize us and the payment provider to keep transaction records necessary for completing transactions, invoicing, refunds, tax, and dispute handling.
We may suspend paid benefits and claw back credits for payment failures, chargebacks, refund abuse, or other abnormal transactions.

4. Credit Consumption

AI voiceover: billed by the duration of the generated voiceover audio. The rate, minimum billable duration, and maximum source video length are shown on the pricing page. Videos that exceed the limit are rejected and not charged.
Watermark removal: billed per successfully parsed share link; failed parses are not charged, and downloading or re-downloading after a successful parse is not charged again. You must own the necessary rights to the video or have authorization, and you may not use this feature to infringe anyone's copyright or other lawful rights.
Estimates and confirmation: the estimated credit cost is shown before a task starts, and the actual charge will not exceed that estimate. If your balance is insufficient for an entire batch, the batch will not start and you must purchase credits first.
No charge on failure: failed tasks, invalid files, or failed link parses are not charged; credits held for the task are returned to your account.
You can view your balance and every credit grant and deduction in "Settings → Credits". If you have questions about a charge, contact us under Section 7.

5. Refunds

The Service is a digital service, and credits are delivered to your account immediately after payment. Refunds are generally not available.
Refund requests are reviewed manually. We will refund after verification in the following cases:
- duplicate charges or clear billing errors: we refund the overcharged amount;
- a continuous outage caused by us lasting more than 72 hours that prevents you from using purchased credits: we refund the amount corresponding to unused purchased credits, or provide equivalent credits with your consent;
- a right of withdrawal or refund that applicable law mandatorily grants you.
Refunds are calculated on unused purchased credits. Bonus credits (including new-user grants and extra credits included with a package) are non-refundable and non-withdrawable. When we refund, we deduct the corresponding credits from your account.
Email support@kukucut.app with your registered email, transaction ID or order number, and reason for the refund. We will confirm within 2 business days, and refunds are usually returned through the original payment method within 5–10 business days (bank or payment provider processing time is additional).
We do not refund consumed credits, bonus credits, accounts terminated for violating these Terms, or chargebacks and payment disputes initiated without good reason.
If you have a question about a charge, contact us first rather than initiating a chargeback without communication.

6. Billing Disputes

If you believe a bill is incorrect, email support@kukucut.app with your account email and transaction information. We will respond within 2 business days and complete our review within 5 business days; if we confirm an overcharge or incorrect charge, we will refund the relevant amount.

7. User Content and License

You retain your rights in the videos, audio, text, images, subtitles, and other materials you upload ("User Content").
To provide the Service, you grant us and our processors a worldwide, non-exclusive, royalty-free, sublicensable license to host, copy, transmit, transcode, transcribe, translate, voice, synthesize, render, display, cache, and delete User Content, for as long as necessary to provide the Service.
You represent and warrant that you own User Content or have all necessary authorizations; that uploading and processing it does not infringe any third party's copyright, trademark, likeness, voice, privacy, or other rights; and that if User Content contains another person's face, voice, or performance, you have obtained their explicit and valid consent. In particular, you must not clone, imitate, or forge another person's voice or likeness without consent.
You may delete uploaded files. After deletion, we will stop using them to provide the Service. See the Privacy Policy for data handling after account deletion.
We do not use User Content to train AI models unless we obtain your explicit consent. We require our AI service providers to process User Content only to provide the Service.

8. AI Output and Intellectual Property

As between you and us, the subtitles, translations, voiceovers, and final videos generated by the Service ("Output") are available for your use. However, Output may contain third-party rights, and AI-generated content may not be protected by copyright in some jurisdictions. We do not guarantee the rights status or registrability of Output.
You should review Output for accuracy, legality, translation and voiceover quality, and obtain any necessary authorizations before publishing, commercial use, or distribution.
The Service itself, including its software, interface, design, trademarks, documentation, and underlying technology, is owned by us or our licensors. We grant you no rights other than those expressly stated in these Terms.
We may use your feedback and suggestions without compensation, and we are not obligated to keep them confidential.

9. Acceptable Use

You may not use the Service to generate, upload, process, store, distribute, or help others create:

Sexual and NSFW content: pornography, nudity, sexual acts, sexual suggestions, adult content, sexual exploitation, or non-consensual intimate imagery.
Violent and graphic content: content that promotes, glorifies, or graphically depicts violence, gore, dismemberment, abuse, animal abuse, self-harm, or suicide, or terrorism, extremism, or incitement to violence.
Hate speech: content that incites hatred, discrimination, humiliation, threats, or harassment based on ethnicity, race, religion, nationality, sex, sexual orientation, gender identity, disability, illness, or another protected characteristic.
Content harmful to minors: any sexualized, sexually exploitative, or sexually abusive content involving minors (including child sexual abuse material, CSAM), grooming or harming minors, endangering minors' physical or mental safety, or attempting to circumvent age restrictions. If we discover such content, we will delete it immediately and report it to the competent authorities as required by law.
Deepfakes and impersonation: cloning, imitating, or synthesizing another person's voice, face, likeness, or identity without their explicit consent, or creating content intended to deceive, defame, manipulate public opinion, commit fraud, or impersonate a person, organization, or official identity.
Infringement of copyright, trademark, and other rights: unauthorized use of another person's film, music, audio, images, fonts, trademarks, likeness, voice, privacy, or trade secrets, or removing or altering rights management information.

You also may not:

violate applicable laws, regulations, or regulatory requirements;
create or distribute fraudulent, misleading, defamatory, or false information;
upload or distribute malware, viruses, phishing content, or spam, or conduct unauthorized scraping, scanning, or stress testing;
bypass quotas, payment limits, access controls, or security measures, or reverse engineer, decompile, or attempt to obtain source code;
resell, rent, white-label, or distribute the Service, or use it to provide a competing product, without our written permission;
use stolen accounts or payment methods, or circumvent regional restrictions;
otherwise abuse the Service, interfere with its operation, or harm others' lawful rights.

If we verify a violation, we may take one or more of the following measures: require you to delete or stop using the content; delete, remove, or block access to the content; issue a warning or restrict generation, upload, export, or sharing; suspend or terminate the account and cancel unused services; preserve evidence and report to law enforcement, regulators, or rights holders. Fees paid for accounts terminated for violations are non-refundable.

10. Reports, Moderation, and Appeals

If you find someone using the Service to generate, upload, or distribute prohibited content, or believe content infringes your rights, please report it:

Email: support@kukucut.app
Subject: Content Report
Please include:
- the link, file name, file ID, or screenshot of the reported content, and when you found it;
- the reported account's email, username, or user ID (if known);
- the violation category (for example, sexual/NSFW, violence/gore, hate speech, harm to minors, deepfake, infringement) and a brief description;
- if you assert copyright, trademark, likeness, or voice rights, proof of ownership, the scope of authorization, and the action you want us to take;
- your contact details. You may report anonymously, but we may not be able to tell you the outcome if you do not provide contact details.

We maintain content safety through "provider safety filtering + human review + report-driven re-review":

Automated filtering: third-party AI model providers may apply safety checks to content they process and may refuse content they consider sensitive. We do not claim to conduct continuous pre-publication automated scanning of all generated content.
Human review: after receiving a report, a provider safety alert, or a high-risk signal, the operator or personnel authorized by us and trained in content safety will review the matter.
Proactive sampling: we may reasonably sample high-risk content and repeatedly reported accounts based on reports, account behavior, and provider alerts.

We initially triage reports and discovered violations as follows:

Level	Typical cases	First response	Target handling
L1 Emergency	CSAM, imminent danger to life, terrorism, non-consensual intimate imagery	Within 2 hours	Within 24 hours
L2 High risk	Sexual/NSFW, violence/gore, hate speech, deepfake/impersonation, clear infringement	Within 24 hours	Within 3 business days
L3 General	Other violations, routine copyright or trademark complaints	Within 3 business days	Within 7 business days
L4 Inquiry/Appeal	Rule questions, false reports, appeals of decisions	Within 5 business days	Within 15 business days

These periods run from the time we receive a report containing the necessary information. If we need additional materials, rights verification, or complex legal analysis, handling may take longer, and we will keep you informed.

If you disagree with a decision, you may email support@kukucut.app within 30 days of the notice with the subject "Moderation Appeal", explaining your reasons and attaching evidence. We will review within the L4 period. The review will be conducted by someone who did not make the original decision; if team size makes that impossible, the operator will re-examine the matter against a written review checklist and record the reasons. The original measure usually remains in effect during the appeal. Except where required by law or with your consent, we will not disclose a reporter's identity to the reported party.

11. Third-Party Services and AI Models

The Service relies on third-party infrastructure, payment, email, and AI model services. The main categories are cloud hosting and storage, payment and merchant of record, email and notifications, speech recognition, subtitle translation and verification, speech synthesis, link parsing, and server-side audio/video composition components.

We provide these providers only with the information necessary for the relevant processing and require them to act on our instructions and not to use it for their own marketing or model training. Third-party services are governed by their own terms and privacy policies. We are not responsible for their outages, errors, data loss, or conduct, but we select processors with reasonable care and require appropriate security and confidentiality measures.

Models, versions, and availability are controlled by providers. We may change models or providers due to provider updates, availability, pricing, or quality, and will update these Terms and the Privacy Policy accordingly.

12. Changes, Suspension, and Termination

We may improve the Service and add, modify, or discontinue features. We will notify you of material changes through the website or email in advance.
We may suspend or terminate your account and access if you violate these Terms, fail to pay, are suspected of fraud or abuse, pose a security risk, or if required by law or a regulator.
You may stop using the Service and delete your account at any time.
After termination, we will delete or anonymize your data under the Privacy Policy, except where the law requires retention.
If we terminate your account because you breached these Terms, paid fees and remaining credits are non-refundable. If we terminate your account without cause or discontinue the Service, we will refund the amount corresponding to unused purchased credits.

13. Disclaimer

The Service is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim all express or implied warranties, including merchantability, fitness for a particular purpose, non-infringement, accuracy, uninterrupted availability, freedom from errors, and freedom from viruses. You use the Service and rely on Output at your own risk. This section does not exclude any warranty or liability that cannot be excluded by law.

14. Limitation of Liability

To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, consequential, or punitive damages, including loss of profits, revenue, data, goodwill, or business opportunities. Our total aggregate liability will not exceed the amount you actually paid for the Service in the 12 months before the claim arose, or, if you used a free service, USD 100 or the equivalent in RMB.

This section does not limit or exclude liability for our intentional misconduct or gross negligence, personal injury, death, or liability that cannot be limited or excluded by law.

15. Indemnity

If you breach these Terms, infringe third-party rights, upload illegal or infringing content, or abuse the Service, and this causes us to suffer third-party claims, penalties, or losses (including reasonable attorneys' fees), you agree to indemnify us and hold us harmless to the extent of that liability. We may choose our own defense strategy and may require your reasonable cooperation.

16. Governing Law and Dispute Resolution

These Terms are governed by the laws of the People's Republic of China (excluding conflict-of-law rules). Any dispute arising from these Terms or the Service shall first be resolved through friendly negotiation for 30 days; if negotiation fails, either party may bring a lawsuit in a people's court with jurisdiction at the operator's location.

These Terms do not affect your rights as a consumer under the law. If applicable law gives you the right to complain to or sue another competent authority, that right is not restricted.

17. Changes to These Terms

We may revise these Terms and post the updated version on the website. We will notify you of material changes through a website notice or email at least 15 days in advance. After the changes take effect, your continued use of the Service means you accept the updated Terms; if you do not agree, you should stop using the Service.

18. General

Severability: if any provision is held invalid or unenforceable, the remaining provisions remain in effect.
Entire agreement: these Terms and the Privacy Policy constitute the entire agreement between you and us regarding the Service.
No waiver: our failure or delay in exercising any right is not a waiver of that right.
Assignment: you may not assign your rights or obligations under these Terms without our written consent; we may assign them in a merger, acquisition, or restructuring.
Force majeure: we are not liable for interruptions or delays caused by natural disasters, war, government action, cyberattacks, third-party infrastructure failures, or other force majeure, but we will take reasonable steps to reduce the impact.
Language: these Terms are available in Chinese and English. If there is a conflict, the Chinese version prevails.
