Terms of Use

These terms govern your access and use of BuildLab, including calculation tools, quantity takeoff, estimation and reference content.

Effective 2026-09-17

PERSONAL PROJECT — this page is for reference only and is not professional legal advice.

1. Scope of service

BuildLab provides online tools for engineering calculation, quantity takeoff, cost estimation, project management and construction data lookup. Features may change, be suspended or be offered in an experimental state.

2. Results are for reference only

All calculation results, quantities, unit prices, suggestions and reports are for reference only; they do not replace design files, reviews, approvals or technical documents signed by a licensed engineer, architect or qualified organization. Users must verify input data and applicable standards and have a qualified professional approve before using for construction, acceptance, payment or safety decisions.

3. Accounts and security

You are responsible for providing accurate information, protecting your login credentials and notifying us immediately if you suspect unauthorized access. Do not share accounts in a way that defeats usage limits or access rights.

4. Permitted use

Do not use BuildLab to breach systems, distribute malware, collect data without permission, violate intellectual property, upload content you have no right to use or disrupt the service. Access may be restricted when we detect security risk or misuse.

5. Your data and content

You retain rights to your project data and uploaded files, while granting BuildLab a limited right to process them as necessary to provide, protect and improve the service. You are responsible for ensuring you have the right to process and upload that data.

6. Availability and third-party services

The service is provided as-is. Some features depend on third-party hosting, payment, analytics or file-processing providers; outages there may disrupt the service.

7. Limitation of liability

To the extent permitted by law, BuildLab is not liable for damages arising from using unverified results, incorrect input data, service interruption or your construction and commercial decisions. Nothing excludes liability that cannot be excluded under Vietnamese law.

8. Changes and termination

We may update these terms when the service or law changes and will record the new effective date on this page. You may stop using the service at any time; data deletion is handled under the Privacy Policy.

9. Service provider identity

[TO BE COMPLETED BY OWNER: legal entity or business name, tax code, registered address and representative].
