Terms of Use

1. Introduction and acceptance

These Terms concern access to and use of the StonePlan Tools website and its available content. Please read them before relying on a calculator result or reusing site material. We ask visitors to use the service responsibly and to observe the conditions below. Whether any provision forms an enforceable agreement depends on proper notice, the circumstances of use and applicable law; simply posting a page does not guarantee legal assent.

Accessing this website does not create an engineer-client, contractor-client, supplier-customer or other professional relationship.

2. What StonePlan Tools provides

StonePlan Tools develops informational guidance and material-estimation calculators for US stone, gravel, driveway, drainage and landscaping projects. The product categories tracked by the website are listed below. A listing marked In development is not a working calculator in this build.

• Crushed Limestone CalculatorOpen available calculator
• Drain Rock CalculatorOpen available calculator
• Asphalt Millings CalculatorOpen available calculator
• Crusher Run CalculatorOpen available calculator
• Stone Dust CalculatorOpen available calculator

Educational guides and measurement examples explain general principles and terminology. StonePlan Tools does not sell materials, arrange delivery, provide installation services, issue engineering certifications or quote for a supplier.

3. Appropriate use of calculator results

Where a calculator is available, its output is an estimate based on the measurements, units and assumptions used. Material volume and weight can be affected by product gradation, bulk density, moisture, void space and whether quantities describe loose delivery or compacted placement. Handling allowances, supplier sales units, order increments and any prices entered by the visitor can also change an order estimate.

Use results as a starting point for planning, then confirm the relevant inputs and product requirements before purchasing or installing material. Neither the formulas nor the displayed precision guarantee an exact quantity, cost saving or finished construction performance. See the accuracy explanation for more detail.

4. No professional engineering or construction services

Content on this website is not a substitute for a site-specific engineering design, structural evaluation, geotechnical investigation, hydraulic drainage design, licensed construction advice, manufacturer installation approval or supplier-confirmed quotation. Projects involving substantial loads, foundations, retaining structures, drainage discharge, traffic or public safety may require local professional input, permits or approvals. Not every small home landscaping project requires a professional engineer.

5. Your measurements and purchasing decisions

Before using an estimate to make a real-world decision, check your actual project measurements, intended finished depth, local product grade, supplier bulk density and its material state, site conditions, relevant installation instructions, local requirements, current prices, purchase units and delivery terms. Review unexpected values rather than assuming an output is correct. These practical checks do not remove any legal rights or protections that apply to you.

6. Permitted and prohibited website use

You may read the guides and use available calculators for ordinary personal, educational and business planning. Please do not disrupt the service, attempt unauthorized access, distribute malicious code, abuse a contact form if one is provided, interfere with other visitors, use automated access in ways that materially impair service availability, or falsely claim an affiliation with StonePlan Tools.

These restrictions are not intended to prohibit ordinary accessibility tools, legitimate search indexing or lawful good-faith research that does not harm the service.

7. Intellectual property

Original writing, software, illustrations and site branding may be protected by applicable intellectual property law. You may refer to information for lawful personal study and project planning; permission for broader copying or redistribution may be needed from the applicable rights holder. The site does not claim ownership of government publications, technical standards, third-party trademarks or independently supplied source data. A citation to another party's work does not transfer its rights to StonePlan Tools.

8. Third-party references and links

Where relevant, educational material may cite the Federal Highway Administration, state transportation agencies, the Concrete Masonry & Hardscapes Association, the National Institute of Standards and Technology, equipment manufacturers and material suppliers. These organizations are independent. Referencing them does not imply they sponsor, approve or endorse StonePlan Tools. External websites may change and are governed by their own terms and privacy practices.

9. Availability and site changes

Features, examples, calculator assumptions, links and articles may be revised, replaced or discontinued. The website may sometimes be unavailable because of maintenance, technical problems or third-party service interruptions. No continuous-availability promise or service-level guarantee is offered.

10. Accuracy and warranty limitations

We aim to explain our methods and limitations clearly, but cannot guarantee that all content is complete, current, suitable for a particular project or free from error. To the extent permitted by applicable law, the informational website and its estimates are offered without a promise that they will meet every individual requirement or produce a specified project outcome. This statement does not exclude any warranty, legal obligation or consumer protection that cannot lawfully be excluded.

11. Limitation of liability

Because the site does not inspect your site or verify supplier specifications, an estimate should not be treated as the sole basis for material orders, safety decisions or installation design. To the extent permitted by applicable law, StonePlan Tools does not assume responsibility for losses arising solely from reliance on unverified assumptions or measurements. Nothing here limits liability or statutory rights that applicable law does not permit us to limit, including responsibility for unlawful conduct. The legal scope and enforceability of this provision require qualified review.

12. Privacy

Information about personal-data handling belongs in the separate Privacy Policy when that policy is available and verified against the actual website services. These Terms do not describe or override those practices. No statement here should be read as a promise that cookies or other data-processing technologies are absent.

13. Changes to these Terms

These Terms may be updated to reflect changes to the website or applicable requirements. A newly approved version should display its effective date here. Check the page for the current published text; no account-based or email change notification is promised.

14. Applicable law and disputes

No US state, court venue, mandatory arbitration process or class-action waiver is designated in this draft. The applicable rules and any available remedies depend on the circumstances and governing law, including mandatory consumer protections. A qualified legal review, informed by the website operator's verified identity and jurisdiction, is required before adopting any specific dispute-resolution provision.

15. Contact and corrections

For background about the website and its editorial approach, see About StonePlan Tools. The current dependency branch does not publish a verified contact form or contact address. A working contact route will be linked here when it has been integrated and checked; no response-time commitment is made.
