Terms of Service

These Terms of Service (“Terms”) govern access to and use of the TeraQuant website, applications, and related services (collectively, the “Service”). By creating an account, signing in, or otherwise using the Service, you agree to these Terms on behalf of yourself and, if applicable, the organisation you represent (the “Customer”).

If you do not agree, do not use the Service. If you accept on behalf of a company or other legal entity, you represent that you have authority to bind that entity.

The Service is provided by TeraQuant (“TeraQuant”, “we”, “us”, or “our”), a Hong Kong construction-tech company offering verification-first MEP (mechanical, electrical, and plumbing) tender takeoff software.

“You” means the individual using the Service and, where the Service is used for a business, the Customer organisation that authorises such use.

Access to protected areas of the Service requires an account. Authentication is provided through Clerk (or a successor identity provider we designate). You must provide accurate registration information and keep it current.

You are responsible for safeguarding your credentials and for all activity under your account. Notify us promptly if you suspect unauthorised access. You must be at least the age of majority in your jurisdiction and capable of forming a binding contract. The Service is intended for professional and business use in connection with construction tendering and related quantity workflows—not for consumers acting outside a trade or profession.

TeraQuant provides software tools that help teams upload and review multi-discipline PDF drawings and Schedule of Rates (SOR) workbooks, run AI vision extraction of quantities and related elements, display evidence overlays and location pins on drawings, compare AI quantities to SOR / Schedule C ground truth by discipline (for example P&D, FS, MVAC, and EL&ELV), and retain an audit trail of claims and review activity.

Features may include page-level extract, guided legend takeoff, geometric length measurement, project dashboards, and related configuration. We may add, modify, or discontinue features with reasonable notice where practicable. The Service is offered on a software-as-a-service basis unless we agree otherwise in writing.

You agree not to:

• use the Service in violation of applicable law, regulation, or third-party rights;
• upload or process content that is unlawful, infringing, defamatory, or that you lack rights to use;
• attempt to gain unauthorised access to the Service, other accounts, or underlying systems;
• interfere with or disrupt the integrity or performance of the Service (including denial-of-service, malware, or excessive automated load beyond permitted APIs);
• reverse engineer, decompile, or disassemble the Service except to the limited extent such restriction is prohibited by applicable law;
• resell, sublicense, or provide the Service to third parties except as expressly authorised; or
• use the Service to train competing models or products using our non-public outputs or platform materials in a way that violates these Terms or other written agreements.

We may investigate suspected violations and suspend or terminate access as described below.

As between you and TeraQuant, you (or your licensors) retain all ownership rights in drawings, PDFs, SOR workbooks, project metadata, annotations, review decisions, and other materials you upload or submit to the Service (“Customer Content”).

You grant TeraQuant a limited, non-exclusive, worldwide licence to host, store, process, transmit, display, and otherwise use Customer Content solely as needed to provide, maintain, secure, and improve the Service, to comply with law, and to act on your documented instructions. This includes using AI and related processing pipelines to extract quantities, generate overlays and claims, and compare results to SOR data you provide.

You represent that you have all rights and permissions necessary to upload Customer Content and to grant the licence above, including any employer, client, or third-party rights in tender documents. We do not claim ownership of your drawings or commercial quantities.

TeraQuant is designed around a verification-first stance: AI outputs (including symbol counts, labels, geometric lengths, Schedule C matches, summaries, and related suggestions) are proposals, not final certified quantities. Humans—typically quantity surveyors, engineers, or other qualified reviewers—must confirm, correct, or reject outputs before relying on them for tenders, contracts, or commercial decisions.

The Service is not a substitute for professional quantity surveying, engineering, design, or legal judgment. Drawing scale, rotation, OCR/vision limits, legend ambiguity, and incomplete uploads can all affect results. You remain solely responsible for the accuracy and completeness of any quantities, submissions, or decisions made using the Service.

TeraQuant and its licensors own all right, title, and interest in the Service, including software, models (to the extent owned or licensed by us), interfaces, documentation, trademarks, and branding, excluding Customer Content. These Terms do not transfer any platform IP to you. You receive only a limited, revocable, non-transferable right to access and use the Service in accordance with these Terms and any order or subscription agreement.

Feedback you provide about the Service may be used by us without obligation to you, to the extent it does not include confidential Customer Content.

Each party may receive non-public information from the other that is marked confidential or that a reasonable person would understand to be confidential given its nature (“Confidential Information”). Customer Content is treated as your Confidential Information. Our product roadmaps, pricing discussions, and non-public security details are our Confidential Information.

The receiving party will use Confidential Information only to perform under these Terms and will protect it with reasonable care. Obligations do not apply to information that is or becomes public through no fault of the receiver, was independently developed, or was rightfully received from a third party without duty of confidentiality. Disclosure may be made if required by law, with notice where legally permitted.

Commercial access may be provided under a separate order form, quotation, pilot, or subscription agreement. Pricing is typically custom-quoted for project or organisation scope; we do not publish a fixed self-serve price list as part of these Terms.

Free trials, demos, or evaluation access may be offered at our discretion, may be limited in time or functionality, and may be withdrawn or converted to paid terms on notice. Unless otherwise agreed in writing, unpaid evaluation use is provided “as is” and may be terminated at any time.

You may stop using the Service at any time. We may suspend or terminate access if you materially breach these Terms, create risk to the Service or other users, fail to pay applicable fees when due, or if we are required to do so by law.

Upon termination, your right to access the Service ends. We may delete or disable access to Customer Content after a reasonable retention period, subject to legal holds, backup cycles, and any written data-return commitments. Provisions that by nature should survive (including ownership, disclaimers, liability limits, indemnity, and governing law) will survive termination.

To the maximum extent permitted by applicable law, the Service is provided on an “as is” and “as available” basis, without warranties of any kind, whether express, implied, or statutory, including implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.

We do not warrant that the Service will be uninterrupted, error-free, or free of harmful components, or that AI extracts, length measurements, SOR matches, or other outputs will be complete or accurate. No oral or written information from us creates a warranty unless expressly set out in a signed agreement.

To the maximum extent permitted by applicable law, TeraQuant and its directors, employees, and suppliers will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or business opportunity, arising out of or related to the Service or these Terms, whether in contract, tort (including negligence), or otherwise, even if advised of the possibility of such damages.

Our aggregate liability arising out of or related to the Service or these Terms will not exceed the greater of (a) the amounts you paid to TeraQuant for the Service in the twelve (12) months before the claim, or (b) HKD 1,000 if you have not paid fees. Some jurisdictions do not allow certain limitations; in those cases, our liability is limited to the fullest extent permitted by law.

You will defend, indemnify, and hold harmless TeraQuant and its officers, directors, and employees from and against reasonable claims, damages, losses, and expenses (including reasonable legal fees) arising from (a) Customer Content, (b) your use of the Service in breach of these Terms or applicable law, or (c) infringement or misappropriation alleged to result from Customer Content or your combination of the Service with materials not provided by us.

These Terms are governed by the laws of the Hong Kong Special Administrative Region (“Hong Kong SAR”), without regard to conflict-of-law principles. The courts of Hong Kong SAR have exclusive jurisdiction over disputes arising out of or relating to these Terms or the Service, subject to any mandatory consumer or other protections that cannot be waived by agreement (which typically do not apply to B2B use).

We may update these Terms from time to time. When we do, we will revise the “Last updated” date and, where changes are material, take reasonable steps to provide notice (for example via the Service, email associated with your account, or a notice on our website). Continued use after the effective date of updated Terms constitutes acceptance, except where applicable law requires additional consent.
