Terms of Service

These Terms of Service ("Terms") govern your use of the MaterialCal website ("the Site", "we", "us"). By accessing or using the Site, you agree to be bound by these Terms. If you don't agree, please don't use the Site.

1. Use of the Site

MaterialCal provides free online calculators for construction, landscaping, and material estimation. You may use the Site for personal or commercial purposes without registration, subject to these Terms.

You agree NOT to:

• Use the Site for any illegal purpose or in violation of any laws
• Attempt to gain unauthorized access to the Site, our servers, or other users' data
• Use automated tools (bots, scrapers) to extract data beyond what's permitted by our robots.txt
• Interfere with or disrupt the Site, including overloading our servers
• Misrepresent your affiliation with us or any other entity
• Copy, reproduce or republish substantial portions of our content without permission (see Intellectual Property below)

2. Calculator Accuracy and Disclaimer

Our calculators are estimating tools, not engineering substitutes. They produce theoretical results based on input dimensions and average material density values. Actual material orders should account for:

• Local supplier variation in density and grading
• Moisture content (wet materials weigh significantly more)
• Compaction and settling during installation
• Project-specific waste and irregularities
• Site conditions, drainage, and grading requirements

For any project involving structural integrity, building permits, or significant financial commitment, consult a licensed professional engineer, contractor, or architect. Our calculators are not a substitute for professional engineering judgment, code compliance review, or supplier-specific quotes.

We make reasonable efforts to ensure formulas, density values and pricing references are accurate and current. However, we make no guarantee of accuracy and accept no liability for decisions made based on calculator results.

3. Intellectual Property

All content on the Site — including calculator interfaces, design, text, images, code, formulas presentations, reference tables, and FAQs — is the property of MaterialCal or our content contributors, protected by copyright and other intellectual property laws.

You may:

• Use calculator results for personal and commercial projects
• Reference and quote short excerpts from articles with attribution and a link back to the source page
• Embed our calculators on your own site using our official embed code (when available)

You may not:

• Copy or republish substantial portions of our written content without permission
• Re-host our calculator code or recreate functionality that's substantially similar
• Remove or modify attribution when using embed widgets
• Use our brand name "MaterialCal" or our logos without written consent

For permission requests, contact [email protected].

4. Third-Party Links

The Site may contain links to third-party websites including affiliate links to suppliers like Home Depot, Lowe's, and Amazon. These third-party sites are not under our control, and we are not responsible for their content, privacy practices, or accuracy.

Affiliate links may pay us a small commission if you make a purchase. This does not affect the price you pay. Our editorial recommendations are not influenced by affiliate relationships — we link to commonly accessible suppliers regardless of commission.

5. Advertising

The Site displays advertising from Google AdSense and may display additional ads from select partners. We don't control which specific ads appear; placement is automated. If you believe an ad is misleading, illegal, or harmful, please report it to us and we will work with the ad network to address it.

6. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, MATERIALCALC AND ITS OPERATORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES ARISING FROM YOUR USE OF THE SITE, INCLUDING BUT NOT LIMITED TO:

• Material under-orders or over-orders based on calculator results
• Project failures attributed to calculator-based estimates
• Lost profits, lost data, or business interruption
• Errors or omissions in calculator formulas, density values, or price references
• Third-party services linked from the Site

OUR TOTAL CUMULATIVE LIABILITY FOR ANY CLAIM ARISING FROM OR RELATED TO THE SITE SHALL NOT EXCEED $50 USD.

7. No Warranty

THE SITE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.

8. Privacy

Our handling of your information is governed by our Privacy Policy, which is incorporated into these Terms by reference.

9. Modifications

We may revise these Terms at any time. Material changes will be flagged on the Site for 30 days before taking effect. Your continued use of the Site after changes constitutes acceptance of the revised Terms. The "Last updated" date reflects the most recent revision.

10. Termination

We reserve the right to refuse service, block access, or otherwise restrict use of the Site to any user, at our discretion, for any reason — including violation of these Terms.

11. Governing Law

These Terms are governed by the laws of the United States and the State of Delaware, without regard to conflict-of-law principles. Any disputes arising from these Terms shall be resolved in the state or federal courts located in Delaware.
