Terms of Service

Terms for using kling-4.ai, the independent Kling 4.0 AI video generator.

2026/07/09

Introduction

These Terms of Service ("Terms") govern your access to and use of kling-4.ai, including our website, AI video generation workspace, account features, APIs, credits, subscriptions, and related services (collectively, the "Service").

kling-4.ai is an independent platform for creating AI video with the Kling model family and related generation providers. We are not affiliated with, sponsored by, or endorsed by Kuaishou Technology or the official Kling AI product.

By accessing or using the Service, you agree to these Terms. If you use the Service on behalf of a company or other organization, you confirm that you have authority to bind that organization.

Eligibility and Accounts

You must be at least 13 years old, or the minimum age required in your country, to use the Service. If you are under the age of majority, you may use the Service only with permission from a parent or legal guardian.

You are responsible for:

  • providing accurate account and billing information;
  • keeping your login credentials secure;
  • all activity that occurs through your account, API keys, browser session, or guest usage;
  • notifying us promptly if you believe your account or API key has been compromised.

We may refuse, suspend, or terminate access if account information is inaccurate, the Service is abused, or use of the Service may create legal, security, or safety risk.

AI Video Generation

The Service lets you submit prompts, images, reference materials, and other inputs ("Input") to generate videos, previews, metadata, and related content ("Output").

AI-generated Output can be unpredictable. You understand that:

  • Output may be inaccurate, incomplete, offensive, or unsuitable for your intended use;
  • similar or identical Output may be generated for other users;
  • Output may not be protectable by copyright in every jurisdiction;
  • the Service does not guarantee that Output is free of third-party rights, likeness rights, trademarks, privacy rights, or publicity rights;
  • you are responsible for reviewing Output before publishing, selling, advertising, or otherwise using it.

Ownership and Licenses

You retain any rights you have in your Input. As between you and kling-4.ai, and to the extent permitted by applicable law, you may use your Output for lawful purposes subject to these Terms, your plan limits, and any checkout terms presented to you.

You grant kling-4.ai a worldwide, non-exclusive, royalty-free license to host, store, process, transmit, reproduce, display, and modify your Input and Output as needed to:

  • provide and operate the Service;
  • generate, store, preview, and deliver Output;
  • troubleshoot, secure, and improve the Service;
  • enforce these Terms and our safety policies;
  • comply with law and respond to support requests.

We do not claim ownership of your Input or Output. We retain all rights in the Service itself, including our website, interface, branding, documentation, code, design, workflows, prompts, templates, and technology.

Commercial Use

Commercial use is available only where your selected plan, checkout page, or written agreement expressly allows it. Free generations are provided for personal evaluation unless we state otherwise.

You are responsible for confirming that your Input and Output can be used in your intended context, including advertising, client work, e-commerce, social media, music videos, film, television, games, and other commercial settings.

Prohibited Uses

You may not use the Service to create, upload, share, or distribute content or activity that:

  • violates any law, regulation, court order, or third-party right;
  • infringes copyright, trademark, trade secret, privacy, publicity, or contractual rights;
  • impersonates a person or organization without clear authorization or disclosure;
  • creates non-consensual intimate imagery, sexual content involving minors, or exploitative content;
  • harasses, threatens, defames, or targets people based on protected characteristics;
  • deceives people about elections, public issues, identity, endorsements, or material facts;
  • promotes self-harm, dangerous instructions, malware, fraud, scams, spam, or illegal activity;
  • attempts to bypass safety filters, rate limits, credits, access controls, or security systems;
  • scrapes, reverse engineers, benchmarks for competitive purposes, or resells the Service without permission;
  • overloads, disrupts, or interferes with the Service or its infrastructure.

We may review, block, remove, or restrict content and accounts when we believe these Terms or applicable laws may have been violated.

Third-Party Services and Model Providers

The Service may rely on third-party providers for AI generation, hosting, storage, payments, email, authentication, analytics, abuse prevention, and customer support. Your use of those components may be subject to third-party terms and policies.

We may route your Input and related metadata to generation providers so they can produce Output. We are not responsible for third-party platforms, model availability, provider outages, or changes made by those providers.

Credits, Subscriptions, and Billing

Some features may require credits, a paid subscription, or a one-time purchase. Prices, credit amounts, renewal terms, plan limits, taxes, and supported payment methods are shown at checkout or in the product interface.

Unless stated otherwise:

  • credits have no cash value and are not transferable;
  • credits may expire according to the plan or promotion through which they were issued;
  • subscriptions renew automatically until canceled;
  • you can cancel future renewals through the billing flow when available, or by contacting support;
  • fees already paid are non-refundable except where required by law or expressly stated at checkout.

If payment fails, is disputed, appears fraudulent, or violates payment processor rules, we may suspend paid features, cancel credits, or terminate access.

API Use

If we provide API access, you are responsible for keeping API keys confidential and for all requests made with your keys. You may not share keys publicly, use the API to bypass product limits, or present the API as your own model service without permission.

We may set or change API rate limits, model availability, credit costs, request size limits, retention settings, and safety controls.

Content Moderation and Enforcement

We may, but are not obligated to, monitor content, prompts, accounts, API usage, payment activity, and abuse signals. We may remove content, limit generations, withhold Output, suspend accounts, revoke credits, or report activity if we believe it is necessary to protect users, third parties, the Service, or the public.

Privacy

Our Privacy Policy explains how we collect, use, share, and protect personal information. By using the Service, you acknowledge that we process information as described in that policy.

Availability and Changes

We aim to keep the Service reliable, but we do not guarantee that it will always be available, error-free, secure, or uninterrupted. AI models, generation quality, processing time, output formats, free quotas, and pricing may change over time.

We may update, suspend, discontinue, or restrict any part of the Service at any time, including features that are experimental, beta, free, or dependent on third-party providers.

Disclaimers

The Service is provided "as is" and "as available." To the maximum extent permitted by law, kling-4.ai disclaims all warranties, whether express, implied, statutory, or otherwise, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, availability, and uninterrupted operation.

We do not provide legal, intellectual property, advertising, medical, financial, or professional advice. You should obtain appropriate professional review before using Output in high-risk or regulated contexts.

Limitation of Liability

To the maximum extent permitted by law, kling-4.ai and its owners, operators, employees, contractors, and service providers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, lost data, business interruption, reputational harm, or the cost of substitute services.

To the maximum extent permitted by law, our total liability for any claim related to the Service will not exceed the greater of: (a) the amount you paid to kling-4.ai for the Service in the three months before the claim arose, or (b) USD $100.

Some jurisdictions do not allow certain limitations of liability, so some limitations may not apply to you.

Indemnity

You agree to defend, indemnify, and hold harmless kling-4.ai from and against claims, damages, losses, liabilities, costs, and expenses arising from your Input, Output, use of the Service, violation of these Terms, violation of law, or violation of third-party rights.

Termination

You may stop using the Service at any time. We may suspend or terminate your access if you violate these Terms, create risk for the Service or others, fail to pay, or use the Service in a way that may expose us or third parties to liability.

After termination, some sections of these Terms will continue to apply, including ownership, licenses needed for operation and enforcement, payment obligations, disclaimers, limitation of liability, indemnity, and dispute-related provisions.

Governing Law and Disputes

These Terms are governed by applicable law without regard to conflict-of-law rules, except where consumer protection laws in your jurisdiction require otherwise. If a dispute arises, please contact us first so we can try to resolve it informally.

Changes to These Terms

We may update these Terms from time to time. When we make material changes, we will update the date on this page and may provide additional notice where appropriate. Your continued use of the Service after changes become effective means you accept the updated Terms.
