Terms of Use

1. Purpose of the website

Buildcetra provides calculators and informational content for construction, renovation, and home-improvement planning.

The calculators are intended to help estimate quantities such as material requirements, dimensions, volumes, areas, and approximate costs. They are provided for general informational and planning purposes only.

2. Estimates, not guarantees

Calculator results are estimates based on the information you enter and the assumptions used by each calculator.

Actual project requirements may differ because of factors including site conditions, measurement accuracy, installation methods, material properties, product specifications, cutting and waste, supplier packaging, availability, and other project-specific conditions.

Buildcetra does not guarantee that a calculated quantity will be the exact amount required for a particular project.

You should verify important quantities before purchasing materials or beginning work.

3. Your inputs and assumptions

You are responsible for entering appropriate measurements, prices, product specifications, and other information into the calculators.

Where a calculator provides an editable default or planning assumption, that value is provided as a starting point and may not be appropriate for every project.

Review the assumptions shown by the calculator and replace them with project- or product-specific information where appropriate.

4. Not professional advice

Buildcetra does not provide structural engineering, architectural, building-code, legal, or other professional advice.

Calculator results should not be used as the sole basis for decisions involving structural capacity, loads, foundations, fire safety, electrical or plumbing systems, fastening requirements, or other safety- or code-critical work.

For these matters, follow applicable building codes, approved project documents, manufacturer instructions, local requirements, and advice from appropriately qualified professionals.

5. Product and manufacturer information

Some calculators may reference product specifications, manufacturer information, industry publications, standards, or other third-party information.

Product specifications and technical information can vary between products, locations, and versions and may change over time.

Always verify relevant specifications using the documentation for the actual product you intend to purchase or use.

References to a manufacturer, product, organization, or standard do not imply endorsement, sponsorship, or affiliation unless explicitly stated.

6. Cost estimates

Where a calculator includes cost estimation, the result is based on prices entered by you unless explicitly stated otherwise.

Estimated costs may not include labor, delivery, equipment, taxes, permits, disposal, regional price differences, or other project expenses.

Buildcetra does not guarantee current market prices or final project costs.

7. Website availability and accuracy

We aim to make the calculators useful and to explain important formulas, assumptions, and limitations clearly. However, we do not guarantee that the website or its content will always be error-free, complete, current, or continuously available.

Calculators, content, features, and methodologies may be corrected, updated, changed, or removed over time.

If you believe a calculator contains an error, please contact us through our Contact page.

8. Third-party links

Buildcetra may contain links to third-party websites or resources.

We are not responsible for the availability, content, accuracy, privacy practices, products, or services of third-party websites.

A link does not necessarily mean that Buildcetra endorses the third party.

9. Advertising and affiliate relationships

Buildcetra does not currently display advertising, sponsored content, or affiliate links.

If any of these are introduced in the future, they will not change the calculation formulas used by our calculators, and these Terms will be updated accordingly.

10. Limitation of liability

To the extent permitted by applicable law, Buildcetra is not responsible for losses, damages, costs, injuries, material shortages or overages, project delays, or other consequences arising from reliance on calculator results or information provided on the website.

You are responsible for verifying information relevant to your project before making purchasing, construction, safety, or financial decisions.

Nothing in these Terms excludes or limits liability where doing so would not be permitted by applicable law.

11. Intellectual property

Unless otherwise indicated, the original website content, calculator interfaces, written explanations, and other original materials on Buildcetra are provided as part of this website and may not be reproduced or redistributed in substantial part without permission.

Third-party names, trademarks, product names, standards, and other third-party materials remain the property of their respective owners.

12. Changes to these Terms

We may update these Terms of Use as the website develops or when our services or practices change.

When the Terms are updated, the “Last updated” date at the top of this page will be revised.
