By using Grey Structure Calculator, you agree to use its calculators and guides as informational planning aids, verify important decisions independently, and avoid interfering with the site or misrepresenting its content.
1. Agreement
These Terms and Conditions govern use of greystructurecalc.com. If you do not agree, stop using the site. The Privacy Policy, Cookie Policy and Disclaimer also apply.
2. Site purpose
The site provides browser-based construction planning calculators, worked examples, methodology and educational guides. It is not a design, contracting, inspection, procurement, certification or approval service.
3. Calculator outputs
Results depend on user inputs and published assumptions. You are responsible for checking dimensions, units, scope, rates and suitability before using an output. No result is a quotation, bill of quantities, structural schedule or guarantee of cost.
4. Acceptable use
You may use public pages and calculators for lawful personal, educational and internal business planning. You may link to public pages accurately and without implying endorsement.
You must not:
- Disrupt, overload, probe or bypass site security.
- Introduce malware, deceptive redirects or abusive automated traffic.
- Use the site to mislead another person about a project price, approval or professional opinion.
- Remove attribution and republish substantial original site content as your own.
- Collect personal information from the site or its users unlawfully.
- Use contact channels for spam, harassment or unlawful material.
5. Saved, copied and shared estimates
Saved estimates remain in local browser storage. You are responsible for devices, downloads, printed copies and URLs you share. A shared calculator URL can expose its embedded input values to recipients, browser history, messaging services or other systems through which it passes.
6. Contact submissions
The contact form prepares an email draft. You retain responsibility for sending it and for having permission to share its contents. By sending a correction or suggestion, you allow the site to review and use it to respond, maintain security and improve or correct the publication. Do not send confidential or infringing material.
7. Intellectual property
Original text, calculator interfaces, code, branding, graphics and editorial compilations are protected by applicable intellectual-property law. Limited quotation, linking and lawful fair use are not prohibited. Mass reproduction, resale, deceptive copying or removal of attribution requires permission unless law provides otherwise.
8. Third-party sources and links
External sources remain controlled by their publishers and may have separate terms, access restrictions and copyright. Linking does not grant a right to reproduce a standard or publication and does not create sponsorship.
9. Advertising and affiliations
The site may display advertising or introduce disclosed affiliate relationships. Advertising does not create a warranty or endorsement. Advertisers and external merchants are responsible for their own products, terms, privacy and transactions.
10. Changes and availability
The site may correct, add, remove or suspend content and functionality. Material methodology changes should be documented, but uninterrupted availability and preservation of locally saved estimates are not guaranteed.
11. Disclaimer of warranties
To the fullest extent permitted by law, the site is provided “as is” and “as available,” without express or implied warranties of accuracy, merchantability, fitness, title, non-infringement, compatibility or uninterrupted operation.
12. Limitation of liability
To the fullest extent permitted by applicable law, the site owner, operators, contributors and service providers are not liable for direct, indirect, incidental, special, consequential or punitive losses related to site access, calculator use, estimates, construction or procurement decisions, third-party links, data loss or interruption. Liability that cannot lawfully be excluded remains unaffected.
13. Responsibility for misuse
You are responsible for losses and claims caused by your unlawful misuse of the site, infringement of another person's rights or violation of these terms, to the extent permitted by law.
14. Governing requirements
You are responsible for complying with the laws, codes, approvals and contractual requirements that apply to your location and project. These terms do not choose a project jurisdiction or replace legal advice.
15. Updates to these terms
Revised terms become effective when posted unless a later date is stated. The update date changes only when the terms materially change.
16. Contact
