Contracting party and scope
These terms apply to LynHub managed professional design services in Mainland China. 青岛泽森引擎信息科技有限公司 (the Company) contracts with customers and bears quotation, agreed performance and after-sales responsibility. Public registration identifier, contractual address and contacts must be truthfully displayed before order confirmation and retained with the order. Formal contracting is unavailable without a verifiable party and valid terms. Professionals are independent suppliers; participation does not replace the Company as customer contracting party. Services follow legally valid confirmed orders, delivery lists and changes expressly confirmed by both parties, identifying inclusions and exclusions and whether construction, purchasing, site measurement, supervision, construction management or approval handling is included. Unlisted independent work not legally promised is not automatically undertaken, but exclusions cannot remove valid promises, agreed services or statutory duties. Mandatory provisions and valid individual negotiations prevail; these terms govern specific matters and the User Agreement general matters.
Contract formation and payment obligations
Choosing a candidate proposal or winning designer or entering a formal service page does not itself form a paid contract. In the normal online flow, the customer reads the fixed-version quotation, terms, actual party and material clauses, actively ticks and clicks 'Confirm order and undertake payment obligations' to form the contract. No default ticking; browsing or ticking does not mean every clause is understood. Customers may request explanations before confirmation. Expired quotations or changes to scope, party or key settings require reconfirmation. Retain relevant versions, text hashes, quotation and choice records, without future-draft substitution. Obligations and payment stages follow the order. This flow does not exclude contracts already legally formed or pre-sale commitments legally forming part of them.
Main order, customer materials and stage payments
The main order specifies exact project and version baseline, milestone scope, outputs, formats, times, price, currency, revision counts and necessary prerequisites. Payments follow milestones; unpaid stages receive no formal delivery. Price and taxes follow the confirmed quotation; extras require valid confirmation. Customers buy from the Company, which separately settles supplier payments. No wallet or fund-custody service is provided. Customers must provide truthful complete areas, layouts, site measurements, structure and utility information, property restrictions, budgets and authorised materials and promptly clarify and confirm key assumptions. The Company reasonably flags and checks obvious contradictions and cannot knowingly use errors and shift all responsibility to customers. Attributable customer errors, omissions, failures to pay, respond or check sites as agreed, or unauthorised construction changes actually obstructing a stage require explanation, demand for correction and reasonable opportunity. The affected stage may be paused or deadlines adjusted to actual impact. Extra work, costs and changes require valid confirmation; simultaneous Company delay is assessed separately. Pausing does not automatically forfeit unused prepayments; termination and refunds follow law and actual completion.
Precise delivery, revisions and changes
Formal delivery is linked to order milestones, agreed outputs, exact files and versions, formats and standards and notified through agreed channels. Customers may check, preview and download authorised versions. Chats, previews and concept sketches do not automatically replace formal delivery or negate actually completed agreed electronic delivery. Replacing historical files must not overwrite confirmed scope and outputs. Correcting non-conforming Company services is not a customer-paid added change. New spaces or outputs, reversal of confirmed baselines or non-defect revisions beyond agreed rounds require prior recording of reasons, scope, version, price and schedule and valid confirmation. Without confirmation, fees or replacement of confirmed outputs are not implied. Ordinary revisions or disputes do not automatically prove agreement to paid changes.
Seven-day review and human acceptance
Review begins when exact deliverables are normally accessible and notice reaches the agreed channel. Customers have seven days to accept, request revisions or dispute. Reading or download faults must first be repaired, with review timing adjusted to actual impact. Seven days without response does not automatically accept delivery or waive rights. After agreed reminders without response, the Company may conduct human acceptance against agreed objective standards, preserving verifiable evidence and specific reasons and notifying the customer. A further seven-day appeal period does not exclude statutory rights. Open revision requests or disputes follow their procedures. Human acceptance is a business decision, not final adjudication; customers may submit contrary evidence and seek legal remedies. Customer delay affecting subsequent stages follows the preceding section's notice and handling.
Correction, refunds and loss liability
Non-conforming services are assessed by defect impact, reparability and contractual purpose. Where reasonably repairable without serious impairment of purpose, explain and prioritise reasonable agreement on correction or re-performance scope and timing. Non-repairability, failure within reasonable time, unsuccessful repair, serious impairment or other lawful termination grounds lead to lawful price reductions, partial or corresponding refunds, termination and damages. Unlimited remedies cannot deprive consumers of lawful choices. Subjective preference changes are distinguished from non-conformity; dissatisfaction does not always yield full refunds or blanket refusal. Customer refunds and Company recourse against suppliers are assessed separately, without automatic equal supplier deductions. Supplier invoices, verification or settlement problems do not excuse Company customer duties. Liability and losses follow legal duties, attribution, causation, reasonable foreseeability at contracting and mitigation; lawful performance-interest compensation is not excluded merely as indirect loss or profit. Unpromised independent opportunities or earnings are not guaranteed. Customer or independent contractor conduct causing or enlarging losses follows lawful attribution. Consumer compensation has no permanent hard order-amount cap. Any non-consumer limit requires genuine prior negotiation of amount, scope and exceptions; this general draft inserts no unconfirmed limit. Personal injury, intentional or grossly negligent property damage and other non-excludable responsibility remain unrestricted.
Customer completion and supplier settlement
Order completion and supplier settlement are independent. When agreed delivery, acceptance and lawful valid responsibility handling and other completion conditions are met, pending supplier invoices or payment review do not negate customer completion or create added duties for completed customer orders. Actual supplier payments still require necessary identity, tax, invoice, receipt and compliance conditions. Completion points are issued only after actual order completion under applicable rules.
Intellectual property, customer assets and project licence
Customers acquire project-specific use licences or expressly agreed order rights after full payment of the applicable service price. Stage licences and output use follow express order terms. Silence does not transfer all copyright; third-party materials and pre-existing rights follow actual licences. Suppliers need authority to grant Company performance rights. Public display and open collaboration rules cannot extend to unauthorised customer information, source files or formal commercial files. Customers truthfully disclose rights and use scope of supplied assets. Attributable unauthorised provision causing valid third-party claims entails actual reasonable losses and necessary enforcement and remedies within their responsibility. The Company provides factual and loss grounds, lawful notice and opportunity to participate; arbitrary settlements are not automatically passed on in full. Company and suppliers retain responsibility for their own infringing provision or processing. Company responsibility and reasonably avoidable increased losses are not shifted to customers.
Site conditions, independent construction and safety approvals
Orders state whether site measurement occurs and who performs it. Unmeasured content relies on customer or site-professional data and explicit assumptions; online images do not guarantee discovery of concealed structures, utilities or other site conditions. Items needing checking must be prominently marked. Site discrepancies require pausing affected high-risk actions and checking; customer data does not remove all professional design-care duties. Structure, load-bearing, fire, gas, water, electrical and construction feasibility require appropriately qualified review against sites and applicable standards and necessary approvals. Property, fire, structural or administrative approvals are not guaranteed; agreed approval work remains a statutory performance duty. Independent contractors bear legal responsibility within their roles for materials, construction quality, drawing deviations and site safety. The Company retains responsibility for design defects, expressly undertaken construction management and other statutory duties despite independent construction.
Communication, evidence and dispute remedies
Customers may request revisions or raise disputes in the order collaboration room. Support, appeals and clause explanations: support@lynhub.com; legal matters and complaints: legal@lynhub.com. The Company explains facts, reasons and basis and provides human review. Text, quotations, exact versions, delivery and action records may be evidence; parties may lawfully rebut them. Hashes, ticks or internal records do not establish understanding or constitute sole final evidence. Mainland China services follow PRC law and applicable mandatory rules. Negotiation and review are not compulsory barriers to legal remedies. Lawful complaints, reports and mediation are available; valid arbitration agreements govern arbitration, otherwise competent courts hear suits. Consumer statutory rights remain. Specific corporate dispute arrangements require separate clear valid agreement, not later unilateral Company selection. Private orders and frozen contracts are accessible only by lawful parties and authorised administration, outside public legal-history search.
Force majeure, versions and existing performance
Force majeure applies only under statutory conditions with causation to inability to perform, and liability follows actual impact by law. Affected parties promptly notify, provide necessary proof and reasonably mitigate. Maintenance, network, supplier or technical Provider failures are not automatically force majeure; corresponding Company performance and remedies remain, and prior own delays and avoidable failures are not automatically excused. Long-term frustration of purpose leads to lawful termination and handling of sums received. Rule changes follow applicable consultation and publication; platform procedures require at least seven days for ordinary and fifteen for major changes, with reasonable transitions for important rights. Catalogue drafts are not effective, dates are not backdated and acceptance is not default. Users may exit lawfully; existing rights, fees and orders follow original effective arrangements and law without unreasonable obstacles. Lawful parties may read, save and continue historical contracts in their frozen versions, with no reduction of existing rights by new drafts. Invalid parts do not affect independently valid remainder; delay is not automatic waiver; assignments require lawful notice or consent.
