BUILDSYNC LIMITED · Hong Kong
Terms of Use
Version: 2026-10-01-v1 · Effective date:
Contact address: Hong Kong Science and Technology Park
[email protected]
1. Scope and agreement
These terms cover the BuildSync public website and, where expressly accepted, BuildSync Workspace. “BuildSync”, “we” and “us” refer to the operator identified above. Website information describes the product and does not itself create a subscription, professional appointment or service-level commitment. Workspace subscriptions require an order or other express agreement and acceptance of the applicable version of these terms. If you act for an organisation, you must have authority to bind it. An executed order, negotiated agreement and data processing agreement prevail over these terms to the extent of a conflict concerning their subject matter. Mandatory law always prevails. A privacy notice explains processing; acknowledging it is not blanket consent to optional processing.
2. Eligibility, accounts and access
Workspace is intended for authorised adult business and professional users. Protect your account and authentication methods, provide accurate account details and promptly report suspected compromise. An organisation may manage its own workspace and invitations, subject to the contract and access permissions. Access to one workspace or project does not authorise access to another. Only invite people who are entitled to receive the relevant information. We may refuse or suspend access where reasonably necessary to address unlawful activity, compromise, material breach or risks to other users. We will give reasons and an opportunity to resolve the issue where practicable, unless doing so would create security risks or breach law.
3. Service scope and professional responsibility
BuildSync assists with organising project information, research, analysis and collaboration. AI outputs, maps, extracted text, quantities, forecasts and regulatory summaries may be incomplete, inaccurate or outdated. They are not statutory approvals, certifications of safety, professional sign-offs, legal opinions, valuations or guarantees of constructability, compliance or financial performance. Appropriately qualified and authorised professionals must check source documents, current requirements, site conditions, assumptions and calculations before decisions, submissions or site work. A workflow label such as “reviewed” records an action within the service; it does not establish a person's professional qualification or an authority's approval. Synthetic demonstrations are illustrative. Product direction and pilot features are not contractual promises unless included in your order.
4. Customer content and limited permission
You and your licensors retain your rights in documents, drawings, models, messages and other content you supply. You must hold the rights, permissions and lawful basis needed to upload, share and instruct processing, including for third-party intellectual property and personal data. You grant us a limited, non-exclusive permission to host, copy, transmit and process that content only to deliver the agreed service, follow authorised instructions, protect the service and meet legal obligations. This is not a transfer of ownership or a general right to publish customer material. The permission ends when processing is no longer necessary, subject to lawful retention and agreed deletion arrangements. Customer publicity, case studies and identifiable examples require separate authorisation. Restrictions in source licences, confidentiality agreements, government datasets and project contracts continue to apply.
5. Outputs and intellectual property
As between you and us, you retain your input rights and may use outputs made for you for your authorised business purposes, subject to third-party rights and your agreement. To the extent we own assignable rights in an output created specifically for you, we assign those rights to you; our pre-existing software, templates, methods and know-how remain ours. This does not promise that an AI output attracts copyright, is unique, is non-infringing or can be exclusively owned. Our brand, website materials and software are protected by applicable intellectual property law. No licence to our source code, internal prompts, orchestration, security design or proprietary datasets is granted except expressly in writing. You must not unlawfully copy protected materials, misappropriate confidential information, remove rights notices, circumvent access controls or reverse engineer except to the extent applicable law permits despite this restriction. This does not prohibit lawful independent development or legitimate criticism, comparison or research conducted without infringement or unauthorised access.
6. Acceptable use
Follow the Acceptable Use Policy. Do not use the service for unlawful activity, unauthorised surveillance, doxxing, infringement, credential theft, malicious code, access-control evasion, abusive automated extraction, or unsafe decisions made solely from AI output. Security testing requires written agreement on scope, except ordinary use and lawful reporting under the Vulnerability Disclosure Policy. Public search engines may index approved public pages in accordance with published crawler instructions; that does not authorise access to private content or bulk extraction of proprietary datasets.
7. Third-party services and connections
Optional connections and AI/OCR processing may involve third-party providers. We will identify material processing and applicable providers through the privacy notice, relevant notices and contractual schedules. Authorise only necessary scopes. Disconnecting a source connection can stop future access but does not automatically erase copies already lawfully imported; deletion follows the applicable process. Independent source websites and services have their own terms. A provider failure may affect functionality; we do not guarantee independent third-party availability. We remain responsible for our contractual obligations and applicable processor oversight duties.
8. Fees and commercial changes
Fees, taxes, usage limits, billing periods, renewals, cancellation and refunds must be stated in your order before purchase. No paid renewal, additional usage charge or non-refundable commitment is created merely by visiting the website. Material pricing or scope changes require the notice and rights set out in your agreement. Preserve all mandatory consumer rights if a consumer transaction is offered.
9. Confidentiality
Each party must protect the other's non-public information identified as confidential or reasonably understood to be confidential, use it only for the agreement and disclose it only to people or approved providers who need it and are bound by suitable confidentiality obligations. This includes customer project and commercial information and BuildSync's non-public technical and business information. Exclusions apply to information lawfully public without breach, independently developed without use of protected information, lawfully received without restriction, or already lawfully known. Legally required disclosure should be limited and preceded by notice where lawful. These duties continue while the information remains confidential; trade-secret protection is not limited by an arbitrary short expiry.
10. Privacy and security
The Privacy Policy describes relevant processing. A signed data processing agreement governs processing on a customer's behalf where applicable. We will use reasonable care and appropriate safeguards required by law and the agreement; no system can guarantee freedom from every incident. Users must use appropriate permissions and avoid including secrets or excessive personal data in support messages. No certification, encryption coverage, service level, data residency or “no training” commitment is implied unless specifically verified and included in the applicable documentation or contract.
11. Warranties and liability
We will provide contracted services with reasonable care and skill. Website information and experimental outputs are supplied without additional warranties to the extent lawful. Nothing excludes liability for death or personal injury caused by negligence where exclusion is prohibited, fraud or fraudulent misrepresentation, or any liability or remedy that cannot lawfully be restricted. Any service-specific liability cap or exclusion must be expressly agreed in the customer order and meet applicable reasonableness and mandatory-law requirements. This website notice does not impose a monetary cap on free visitors. Confidentiality, personal-data incidents, intellectual property and wilful misconduct require express treatment in any agreed allocation. Mandatory rights under applicable Hong Kong, UK, Australian or other consumer law are preserved. No blanket user indemnity is imposed by these Terms.
12. Ending the service and data
You may terminate or cancel as provided in the order. We may terminate for a material breach not remedied after reasonable notice, or immediately where necessary to prevent serious harm or comply with law. Where practicable, we provide an opportunity to export authorised customer data before access ends. Export formats, the export window, operational deletion and backup expiry must be specified in the agreed retention schedule. Archiving, disconnection and soft deletion are not the same as erasure. Lawful record retention and legal holds must be limited, protected and explained. Termination does not transfer ownership or extinguish accrued rights.
13. Changes and notices
We maintain dated versions and give reasonable advance notice of material contractual changes. Obtain fresh acceptance where legally or contractually required. Changes will not retrospectively expand content licences or reduce mandatory rights. Security or legal changes may take effect sooner with an explanation where lawful. Contact us at [email protected]; formal notices follow the order.
14. Governing law and disputes
The agreed governing law is Hong Kong law, with Hong Kong courts as the agreed forum. Parties should first attempt to resolve disputes through the legal contact. This provision does not remove mandatory protections or court access available to consumers under their applicable law. Sever an unenforceable provision only to the extent lawful; the remainder continues.
15. Languages and related documents
English and Traditional Chinese versions are available with equivalent substance. English and Traditional Chinese versions have equal status unless a signed order expressly specifies a prevailing version, subject to mandatory law. Related documents: Privacy Policy, Cookies and Tracking Notice, Acceptable Use Policy, AI and Professional Use Policy, Vulnerability Disclosure Policy and Intellectual Property Reporting Policy. The data processing agreement applies only when executed or validly incorporated.
