Terms of Service
Last updated: 2026-07-26
Welcome to Lingtu AI. These Terms of Service govern your access to and use of Lingtu AI, including our website, merchant dashboard, customer intake links, AI-assisted brief collection tools, file management features, design prompt workflows, billing features, and related services. By creating an account, purchasing a plan, sharing a customer link, or otherwise using the service, you agree to these Terms.
1. Service Overview
Lingtu AI helps print shops, sign makers, advertising studios, and creative teams collect client requirements, organize uploaded materials, generate AI-assisted questions, summarize ad briefs, create design prompts, and manage design-related order workflows. The service is intended to support human teams and does not replace professional review, legal review, design judgment, or client approval.
2. Eligibility and Authority
You may use Lingtu AI only if you can legally enter into a binding agreement. If you use the service on behalf of a business, shop, agency, or other organization, you represent that you have authority to bind that organization to these Terms. You are responsible for ensuring that all users you invite or authorize comply with these Terms.
3. Account Registration and Security
You must provide accurate account and contact information and keep it current. You are responsible for maintaining the confidentiality of your login credentials and for all activity under your account. Notify us immediately at support@lingtu.io if you suspect unauthorized access, credential compromise, billing misuse, or any security issue affecting your account.
4. Merchant Responsibilities
You are responsible for your client relationships, order details, design decisions, quotes, deadlines, approvals, printing requirements, production files, and final delivery. You must review AI-generated questions, summaries, prompts, and outputs before using them commercially. You are also responsible for obtaining any client consents required to collect, upload, process, or share client information and materials through Lingtu AI.
5. Customer Intake Links
The service may allow you to create links, forms, QR codes, or other intake pages for your clients. You are responsible for how you distribute those links, the instructions you provide to clients, and the information you request. You may not use intake links for spam, phishing, misleading collection, unlawful data gathering, or collecting sensitive information that is not reasonably necessary for your order workflow.
6. User Content and Client Materials
You retain ownership of materials that you or your clients submit, including text, images, logos, brand references, files, order notes, and customer responses. You grant Lingtu AI a limited, non-exclusive license to host, process, transmit, display, transform, summarize, and analyze that content solely as needed to provide, secure, maintain, and improve the service. You represent that you have the rights and permissions needed to upload and process all submitted content.
7. Acceptable Use
You may not use Lingtu AI to violate laws, infringe intellectual property rights, impersonate others, deceive clients, distribute malware, scrape or reverse engineer the service, overload infrastructure, bypass access controls, interfere with other users, collect data without permission, or submit abusive, defamatory, discriminatory, exploitative, or harmful content. You also may not use the service to request, create, generate, edit, summarize, promote, distribute, or facilitate workplace-inappropriate, adult, pornographic, explicit sexual, sexually suggestive, nude, or fetish content. We may refuse, block, remove, suspend, or restrict any request, output, file, intake link, account, or workflow that appears to violate these rules.
8. Content Restrictions: Adult and Workplace-Inappropriate Material
Lingtu AI is designed for professional advertising, print, signage, and creative business workflows. The service may not be used to generate or process content that is not appropriate for a workplace setting, including adult entertainment, pornography, explicit sexual acts, nudity intended to be sexual, sexually suggestive depictions, erotic roleplay, fetish material, sexualized minors, non-consensual sexual content, sexual exploitation, or any content that would reasonably be considered unsafe, harassing, degrading, or inappropriate in a professional environment.
9. Copyright, Trademark, Publicity, and Likeness Rights
You may not use Lingtu AI to copy, imitate, reproduce, modify, distribute, or commercialize copyrighted works, trademarks, logos, brand assets, images, characters, artwork, celebrity identities, customer materials, or third-party creative assets unless you have the necessary rights, licenses, permissions, or legal basis. You may not use the service to create misleading endorsements, unauthorized advertisements, impersonations, deepfakes, or content that violates a person’s portrait rights, publicity rights, privacy rights, image rights, voice rights, or other personal rights. You are responsible for confirming that all submitted materials and requested outputs are lawful to use.
10. AI Features and Output
Lingtu AI may use artificial intelligence to ask follow-up questions, summarize requirements, draft prompts, classify missing information, or generate creative suggestions. AI output can be inaccurate, incomplete, biased, outdated, or unsuitable for a specific use. You must independently review output before printing, publishing, producing, quoting, or delivering any work. Lingtu AI does not guarantee that AI output will be unique, error-free, non-infringing, legally compliant, or fit for a particular purpose.
11. Plans, Billing, and AI Credits
Available plans, usage limits, AI credits, image generation allowances, storage limits, and prices are shown on our pricing pages, checkout pages, dashboard, or order forms. Unless otherwise stated, prices are intended to be charged in U.S. dollars. You authorize us or our payment providers to charge applicable fees, taxes, renewals, and usage purchases. AI credits are digital usage units and may be consumed when requests are submitted, even if you later discard the result.
12. Taxes and Payment Providers
You are responsible for any taxes, duties, bank fees, currency conversion fees, or payment processing fees that may apply to your purchases, unless they are already included in the displayed price. Payments may be processed by third-party payment providers, and your use of those payment methods may be subject to the provider terms and privacy policies.
13. Intellectual Property of Lingtu AI
Lingtu AI and its software, interface, workflows, databases, documentation, branding, templates, prompts, design, trademarks, service marks, and related technology are owned by Lingtu AI or its licensors. These Terms do not transfer any ownership rights to you. You may not copy, resell, sublicense, reproduce, modify, or create derivative services from Lingtu AI except as expressly permitted by these Terms.
14. Third-Party Services
The service may rely on third-party infrastructure, AI providers, hosting providers, analytics tools, payment providers, email providers, or storage systems. We are not responsible for third-party services that we do not control, but we use reasonable efforts to choose providers that support the service. Third-party outages, policy changes, rate limits, or processing failures may affect availability or output quality.
15. Privacy and Data Protection
Our Privacy Policy explains how we collect, use, store, and protect personal information. By using Lingtu AI, you agree that information may be processed as described in the Privacy Policy. You are responsible for providing any notices and obtaining any consents required from your clients or team members before submitting their personal information or materials to the service.
16. Confidentiality
If you submit non-public business or client information, we will treat it as confidential and use it only to provide, secure, support, or improve the service, unless disclosure is required by law or necessary to protect rights, safety, or service integrity. You must also protect any non-public information you access through Lingtu AI and may not share it outside your legitimate business workflow.
17. Suspension and Termination
You may stop using the service at any time. We may suspend or terminate access if you violate these Terms, fail to pay fees, create security or legal risk, misuse the service, or if continued access could harm Lingtu AI, other users, clients, or third-party providers. Termination may result in loss of access to your dashboard, intake links, files, credits, and stored data, subject to applicable law and our retention practices.
18. Service Availability and Changes
We aim to provide a reliable service, but we do not guarantee uninterrupted, error-free, or permanently available access. Features may change, be added, be limited, or be discontinued. We may perform maintenance, update models, modify plan limits, or change workflows. When changes materially affect paid users, we will use reasonable efforts to provide notice where practical.
19. Disclaimers
To the maximum extent permitted by law, Lingtu AI is provided on an as-is and as-available basis without warranties of any kind, whether express, implied, statutory, or otherwise. We disclaim warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, availability, and reliability. You are responsible for validating all outputs, files, instructions, and final deliverables.
20. Limitation of Liability
To the maximum extent permitted by law, Lingtu AI will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost revenue, lost data, business interruption, production errors, print errors, client disputes, or reputational harm. Our total liability for any claim relating to the service will not exceed the amount you paid to Lingtu AI for the service during the three months before the event giving rise to the claim.
21. Indemnification
You agree to defend, indemnify, and hold Lingtu AI harmless from claims, damages, losses, liabilities, costs, and expenses arising from your content, client materials, use of the service, violation of these Terms, violation of law, infringement of third-party rights, or disputes between you and your clients or team members.
22. Changes to These Terms
We may update these Terms from time to time. Updated Terms will be posted on this page with a revised date or made available through the service. Continued use of Lingtu AI after updated Terms take effect means you accept the revised Terms.
