Welcome to Lingying. We provide AI assistance, application creation and related project services. These Terms explain your rights and obligations when using our services. The Lingying Privacy Policy separately explains personal information processing.

Please pay particular attention to execution permissions in Section 4, sharing in Section 5, charges and refunds in Sections 7–8, termination and liability in Sections 10–11, and dispute resolution in Section 13. You may request clarification through our contact channels before accepting. Registration and sign-in provide document links and an affirmative checkbox. Acceptance does not replace separate consent required by applicable law.

1. Scope and related rules

1.1 These Terms cover our official website, web workspace, desktop client and the account, AI conversation, code and file generation, project management, preview, export, publication, automation, skills, plugin management, membership and balance services we directly provide.

1.2 Available features, supported regions, system requirements and limits depend on the relevant version and what is expressly presented at purchase. A model brand shown in the interface identifies a product service; it does not mean that we trained every underlying model or remove our obligation to disclose actual data recipients.

1.3 Orders, specific rules and permission notices you expressly confirm supplement these Terms for their stated subject matter. Privacy matters are governed by the Privacy Policy. Inconsistencies are interpreted according to applicable law, specific commitments at purchase and a reading that clarifies user rights. Backend settings and later announcements cannot retroactively diminish purchased rights.

1.4 Third-party products, plugins, app stores and applications operated by other users have their own terms. We remain responsible for the services and processing we provide.

2. Accounts, identity and minors

2.1 Use a supported phone number you are entitled to use. First successful verification may create an account; accounts with a configured password may sign in with it. Protect verification codes, passwords and session credentials. Do not rent, transfer or use an account to impersonate others.

2.2 Maintain accurate account information and manage devices and permissions. If you find unauthorized access, unusual charges or unknown tasks, stop the relevant activity and contact us. Authorization, security measures and each party’s fault must be considered in assigning responsibility; possession of a login credential alone does not exclude our responsibility.

2.3 If acting for an organization, obtain the necessary authority and comply with its rules and applicable law when handling organizational materials, confidential information and other people’s information.

2.4 The service is not directed to children. Users under 14 must not independently register or submit personal information; services directed to the United States also do not accept independent registration by children under 13. Other minors require guardian consent and guidance; paid purchases require guardian consent. Phone verification is not age verification. Guardians may contact us about child accounts or use and purchases without appropriate consent.

3. AI services and their limits

3.1 After submission, Lingying processes your input using the task, selected reasoning effort, context and tool permissions, and forwards necessary content through our backend to configured model services. Output and tool results may appear progressively. Networks, model response times, file sizes and tools affect duration; submitting a task does not guarantee a fixed completion time.

3.2 AI output may contain errors, omissions, bias, similar material or code unsuitable for your target environment. Check it against original sources. Medical, legal, financial and similar output does not replace qualified professional advice and must not be the sole basis for decisions materially affecting people or property.

3.3 Test generated applications and code on target devices, dependency versions and environments. Web previews, simulated device frames and packaged environments may differ. A preview alone does not establish app store acceptance, particular performance or production readiness.

3.4 User content is processed for your tasks and lawful service purposes. These Terms do not authorize unrestricted use of private prompts, files or projects for advertising or foundation-model training. New uses require notice and the applicable consent process. The actual upstream model and tool chain is addressed in our Privacy Policy and third-party disclosure; this clause is not an assurance about unverified third-party training, logs or retention.

4. Execution permissions, automation and external actions

4.1 Subject to your instructions and permission mode, tasks may read selected files, edit code, execute commands, install dependencies, access networks, start services or operate browsers and local applications. Modes such as “Full access” may allow actions affecting files or external services without an additional confirmation for every action. Review the scope, back up important files and supervise high-impact actions such as payments, publication or account changes.

4.2 You must actively start demonstration recording. Recorded screens and actions may be used to create or execute skills. Avoid recording passwords, verification codes and unrelated people’s information; inspect recordings and skills before sharing. Manage screen recording and accessibility permissions through the operating system. Revoking them affects dependent features.

4.3 Scheduled tasks can run when their operating conditions are met. Local tasks depend on the device and relevant programs being available; cloud tasks may continue after you close the web page. Check schedules, instructions, connected accounts and costs, and disable unneeded tasks. Stopping a task does not reverse completed actions or consumed usage.

4.4 Use trusted plugins and skills and follow their licenses and service rules. Connecting an external account or granting plugin access is not blanket authorization to process all personal information. Connections and permissions may be revoked. We do not require external account passwords in ordinary chat or support tickets.

4.5 Completion notifications are optional. After sending a task, you may choose completion alerts and grant browser or system permission, or manage them in Settings. Denying permission does not prevent execution. Delivery depends on the browser page or desktop program remaining available; this is not a promise of persistent offline push delivery.

5. Storage, cloud execution and sharing

5.1 Production desktop and web services share an account, membership and balance but store their workspaces separately. Desktop projects, conversations and files are primarily local; web work content is stored on servers. A shared account does not mean that local files are automatically synchronized or backed up in the cloud. AI requests, uploads and publication still transmit necessary content.

5.2 Publication uploads are limited to files needed to run the application. Dependency directories, caches, logs, backups, tests and private credentials should not accompany a publicly uploaded workspace. Supported hosting formats and resources depend on actual features; publishing static pages does not promise support for arbitrary backends, databases or persistent processes.

5.3 File storage is not runtime memory, processor capacity, bandwidth or a dedicated server. Application counts, build limits and resources follow the purchased plan; particular concurrency or unlimited execution is not guaranteed. Limits may restrict additional storage, builds or publication. Changes affecting existing content and services require lawful notice; we do not delete purchased storage content without notice.

5.4 Current Lingying sharing requires viewers to sign in; other signed-in users holding a valid link can view it without individual approval. Sign-in is not a private invitation, confidentiality agreement or copy protection. Check personal information, confidential material, credentials, code and asset rights before publishing. Sharing grants access to published content, not editing rights to your private workspace.

5.5 Current cloud projects can be restored for seven days after moving to trash. Emptying trash or expiry clears primary project content. Unpublishing, deleting a project or closing an account may disable access but cannot recall copies, screenshots or forwarded content already saved by others. Deletion and backup exceptions are in the Privacy Policy. Export important local and cloud material yourself.

5.6 You are responsible for applications you independently operate and their end users, including applicable content, privacy, payment, intellectual property and security requirements. We remain responsible for our own hosting, account and processing activities.

6. Content rights and acceptable use

6.1 You retain the rights you lawfully hold in inputs, files, projects and other user content. You authorize us to use that content only as necessary to provide the requested service, store, transmit and display it, protect security, troubleshoot and address disputes. This does not transfer ownership or grant unrelated permanent commercial exploitation rights.

6.2 You may use, modify and export AI output where lawful and without infringing third-party rights. We do not claim exclusive ownership merely by generating it. Protection and third-party rights depend on the content and applicable law. Open-source code and third-party assets remain subject to their licenses.

6.3 Lingying software, marks, interfaces and proprietary technology belong to us or their right holders. You receive a limited, non-exclusive, non-transferable right to use the service under these Terms. Activities allowed by law or open-source licenses are not restricted without a lawful basis.

6.4 Do not use the service for unlawful activities or prohibited information, fraud, infringement, harassment, discrimination, malicious attacks, data theft, unauthorized access, spam, or circumvention of security, billing or access controls. Do not fabricate AI material as authentic evidence, impersonate people, or remove legally required generated-content labels.

6.5 We may lawfully refuse generation, stop execution, limit distribution, remove content, preserve necessary records or report unlawful, harmful or infringing conduct. Measures should be proportionate to risk. Reports and appeals may be submitted through tickets or email. Legitimate criticism, complaints and lawful exercise of rights are not excluded merely to protect the platform.

7. Balance, membership and payments

7.1 Trial allowances, plans, billing regions, monthly/quarterly/annual prices, included balance, validity and resource quotas follow the purchase display and order record. Review the transaction and total before confirming. Later price changes do not retroactively change paid order quotes.

7.2 A membership “subscription” currently means an affirmative purchase for a specified period, not automatic renewal or recurring payment authorization. Further purchases require a new order. Membership follows its actual start and end times; included service balance is delivered according to the order. Other platforms’ monthly allocation and monthly expiry rules are not imported into Lingying.

7.3 Balance is for service consumption, not a deposit or freely transferable, withdrawable cash. Promotional balance is a service benefit. New expiry rules must be stated before allocation and cannot retroactively erase existing rights. Referral rewards follow activity rules and verified transactions; no fixed return is guaranteed and sham registrations, transactions and reward abuse are prohibited.

7.4 A task may reserve balance before execution, then settle verified model, image or tool usage and release unused reservations. Cancellation, failure or dissatisfaction does not necessarily mean no usage occurred; usage that did not occur should not be charged. Request human review of unusual usage, unreleased reservations or charges. Model-generated statements are not accounting evidence.

7.5 CNY top-ups and membership purchases use the available Alipay and WeChat Pay channels. USD memberships use one-time PayPal Checkout payments, without automatic renewal. Available methods are shown at checkout. Membership and included service credit are delivered after server-side payment verification; opening checkout, returning to the app or clicking “I have paid” is not proof of payment. USD balance top-ups and storage expansion are not currently offered. Use official purchase channels. We do not request full card details, payment passwords or payment verification codes.

7.6 Invoice, payment, fulfillment and billing questions may be submitted with an order number and necessary evidence. Do not include unrelated sensitive material. Order records, actual quotes and valid evidence support review; a display failure alone does not negate a confirmed payment.

8. Refunds and transaction disputes

8.1 Membership, delivered digital services and actually consumed usage generally do not offer voluntary refunds for a change of mind, non-use or subjective dissatisfaction with generated results. There is no self-service refund entry on the balance page. This does not exclude statutory cancellation, refund, return of prepaid funds or compensation rights, and unused prepaid balance is not automatically treated as a fully consumed service.

8.2 Report duplicate or incorrect charges, payment without delivery, failure to provide the agreed service, discontinuation and other legally refundable situations through tickets or email. We review the amount paid, performance and legal basis and communicate the outcome. Legally due refunds are processed through the original payment channel; receipt depends on that channel. You retain legal complaint and remedy options.

8.3 A refund adjusts the corresponding order’s balance, membership period, promotional benefits and referral commission. The same payment is not refunded twice and unrelated orders’ rights are not cancelled without a basis. Used promotional balance, reservations or an inability to automate processing do not by themselves defeat a statutory refund. Commission recovery follows referral settlement rules, not arbitrary deductions from future top-ups.

8.4 Mandatory protections for minors, digital content, prepaid funds and other transactions prevail. These Terms do not waive statutory rights or grant us an exclusive final right of interpretation.

9. Personal information and confidentiality

9.1 The Privacy Policy and third-party disclosure explain categories, purposes, permissions, recipients, retention and rights. Accepting these Terms does not authorize unrelated collection, public disclosure or all cross-border processing.

9.2 Non-public material we encounter while delivering services is processed only within lawful necessary purposes. Obtain a lawful basis to handle others’ material. Separately agreed organizational confidentiality terms apply as agreed. Ordinary accounts do not automatically provide dedicated deployment, zero logging or regulated-industry compliance services.

10. Changes, restrictions, closure and termination

10.1 We may maintain or update services. Material changes to prices, core purchased rights, data purposes and other important matters require appropriate notice of changes and effective dates. Required renewed or separate consent must be obtained. Users who disagree may stop affected features and address unperformed paid rights under applicable law. Continued use does not replace legally required express consent.

10.2 The desktop client may check compatible versions in the background. Downloads begin on your click and are verified; once ready, restart may follow the client workflow, while active tasks prevent an update restart. Version checks do not upload local projects, chats or attachments.

10.3 Proportionate responses to misuse or anomalies may include warnings, rate limits, feature restrictions, suspension or termination. Urgent risks may be addressed first; where lawful, we explain reasons and provide appeals. Restriction does not automatically forfeit paid balance without a basis.

10.4 Close an account through “Settings → Account & security → Delete account” after verifying its phone number. Pending payments, refunds, undelivered orders and active tasks must be addressed first; protected administrator accounts require support-assisted handover. Closure is irreversible: old membership, balance and content are not automatically transferred to a new account. Export materials and address outstanding rights first. Signing out or uninstalling is not account closure.

10.5 Closure disables access, revokes sessions, removes the login phone number and password, stops cloud scheduled tasks and disables associated sharing. It does not immediately physically erase every business, financial or backup record. Retention is explained in the Privacy Policy. The same phone number must wait 30 days to register again; historical rewards and trial usage do not reset.

10.6 If we discontinue the entire service, we provide legally required advance notice and practicable export and unperformed-rights handling. Settlement, confidentiality, intellectual property, privacy and dispute obligations survive where their nature requires.

11. Service safeguards and liability

11.1 We use security and operational measures appropriate to the service. Maintenance, network problems, third-party interruptions and force majeure may affect availability. We make reasonable efforts to notify foreseeable major interruptions, repair faults and mitigate loss.

11.2 Back up important materials and reasonably review output and external actions. Non-performance, data loss, unauthorized execution and other disputes are assessed under applicable law, specific commitments, causation and fault. Third-party participation or AI uncertainty does not categorically remove our duties.

11.3 These Terms do not exclude or limit liability for intentional misconduct, gross negligence, personal injury, unlawful personal information processing or other liability that cannot lawfully be excluded. They do not place all risk on users or impose a blanket liability cap equal to membership fees. Force majeure is addressed by law, including notice, mitigation and treatment of unperformed payments.

12. Contact, complaints and appeals

12.1 Submit account, billing, content, security, privacy and service disputes through “Help & tickets” or yanwancy@gmail.com. Provide necessary account identification, order or task identifiers, time, issue and requested action; rights complaints may require evidence of entitlement. Do not send passwords or unnecessary identity documents.

12.2 We review facts and lawfully communicate outcomes or necessary supporting materials. Appeal content or account measures through the same channels. Negotiation and appeals do not prevent lawful complaints, mediation or proceedings. Notices use the app, website or lawfully provided contact details; these Terms do not authorize unsolicited marketing texts.

13. Governing law and miscellaneous

13.1 Mainland China service relationships are governed by PRC law. Mandatory consumer, privacy and child protections applicable elsewhere are not excluded by currency, phone prefix or these Terms.

13.2 Parties may first seek resolution by discussion. Either party may bring proceedings before a court with lawful jurisdiction, or pursue lawful complaints and mediation. Consumers are not required to waive statutory jurisdiction or other remedies.

13.3 Chinese, English and Traditional Chinese display versions should convey equivalent rights and obligations. Differences are resolved under applicable law and the relevant relationship; Chinese governs Mainland China services without diminishing mandatory rights through translation differences. Invalid or unenforceable clauses do not invalidate the remaining lawful provisions.
