Terms of Service

1. Acceptance of These Terms

By accessing footycalc.com (the "Service"), you agree to be bound by these Terms of Service. If you do not agree, please stop using the Service. The Service is operated by Richard Taylor, sole proprietor, with a mailing address at 1191 Aspen Blvd, Juneau, AK 99801, United States ("we", "us", "FootyCalc").

2. What The Service Is

The Service provides free, web-based square footage calculators and related educational content. All calculations run locally in your web browser: the arithmetic lives in /js/calc-core.js and is executed by your own machine. Submitting dimensions to a calculator does not send those numbers to us.

The Service also publishes machine-readable endpoints on purpose — an embeddable widget, an agent service document, a JSON lookup API, and an MCP server. Section 8 governs their use.

3. Use at Your Own Risk

We strive for accuracy, but our calculators are for informational purposes only. You should independently verify any numbers you rely on for:

• Construction, remodeling, or material purchasing decisions.
• Real estate listings, appraisals, or legal filings.
• Insurance claims or tax reporting.
• Zoning, permit, or code compliance.

Consult a licensed professional (architect, engineer, surveyor, appraiser, or contractor) for decisions of consequence. Where a page shows a waste factor or a coverage rate, that figure is a labeled assumption on the page, not a guarantee from a trade body — read the assumption before you buy material.

4. No Warranty

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT.

5. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, RICHARD TAYLOR AND FOOTYCALC WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES ARISING FROM YOUR USE OF THE SERVICE. OUR TOTAL AGGREGATE LIABILITY WILL NOT EXCEED USD $50.

6. Intellectual Property: Two Different Licenses

All content on the Service — calculators, articles, design, and code — is owned by Richard Taylor / FootyCalc or licensed to us, and protected by copyright and other laws. Because the embed widget and ordinary site use serve different purposes, they are licensed separately, and the two licenses are stated here rather than left to be inferred.

6.1 Browsing and using the site (default license)

You may use the Service itself for personal, non-commercial purposes. In practical terms: run calculations for your own project, link to any page, and quote a short passage with attribution and a link back. Business use of the pages — for example scraping them into a paid report, or republishing our guides wholesale on a commercial site — is not licensed by this section and needs written permission.

6.2 Embedding the widget (explicit commercial carve-out)

Section 6.1 does not limit the embed product. Through /developers/embed-calculator/ we additionally grant a license to embed our calculator widget in your own website or application, for personal or commercial use. A contractor site, a real-estate listing page, and a monetized blog may all embed it. Conditions of that license:

• Embed only pages under /embed/, using the published script tag — do not frame the rest of footycalc.com.
• Keep the attribution link visible; the embedded page renders it at the bottom of the iframe, and it must not be hidden or covered by host CSS.
• Do not modify or re-author the iframe content, and do not pass data-host to point visitors at a copy of the code you host yourself unless that copy is ours.

If this section and section 6.1 ever appear to conflict about an embed, this section governs the embed. That carve-out is deliberate: a "non-commercial only" clause sitting above an invite to use the widget on a business site would be a contradiction we would rather fix in the terms than leave for you to guess about.

6.3 Screenshots and results

You may share or embed screenshots of calculation results you produced — a quote from a job, a post, a bid sheet. That permission covers the picture of your own output; it is not permission to iframe the calculator page itself, which is what section 6.2 is for.

6.4 What we do not allow

• Scraping, copying, or redistributing the content at scale without written permission.
• Building a site, app, or product that is substantially our pages or our widget with the names changed.
• Removing or obscuring attribution, or passing off the widget as your own software.
• Using the Service to probe, overload, or disrupt it for other visitors.

7. Third-Party Content and Advertising

The Service displays advertisements through Google AdSense, and only after you click Accept on the cookie banner — see Cookie Policy and Privacy Policy. We are not responsible for the content, accuracy, or privacy practices of any advertiser. Our publisher account is disclosed in /ads.txt so you can check who is actually serving ads on this domain.

Some pages link to standards bodies, supplier data, or reference documents. Those links are for verification; we do not control the pages they point to, and a link is not an endorsement.

8. Automated and AI Access

We publish machine entry points openly, so the honest thing is to publish the rules for them too. Everything below describes what the Service actually does today, not an aspiration.

8.1 What we publish for machines

No public read endpoint requires an account, token, or key. /agent-auth/* returns HTTP 503 by design, so an agent that tries to register is told plainly that there is nothing to register against rather than being silently redirected.

8.2 What we ask automated readers to do

• Cite the page. Attribute to FootyCalc and link the specific footycalc.com URL you used, so a reader can check the number at source.
• Preserve what the Service returned — paths, units (sq ft), and dates. Do not silently convert or round.
• Leave unknowns unknown. If the Service does not state a figure, say so. Do not invent measurements, prices, or code points and attribute them to us.
• Use the widget, not a frame around the site (section 6.2), and honour the Disallow lines in /robots.txt, which cover our build inputs rather than any content.

8.3 What we do not authorize

We do not grant a license to ingest this site for training or fine-tuning a model, or to rebuild our pages or widget as your own product. Our crawler preference states it in machine-readable form:

Content-Signal: search=yes, ai-input=yes, ai-train=no

To be equally plain about what that line is worth: Content-Signal is not part of the RFC 9309 robots.txt protocol. Section 2.2.4 of that document says only that "Crawlers MAY interpret other records that are not part of the robots.txt protocol" and that "Crawlers MAY be lenient when interpreting other records", and RFC 9309 itself states that "These rules are not a form of access authorization." So the line is a stated preference, not a technical barrier or a license we can enforce from the edge. If you are building a product that needs a training or redistribution license, email us at the address in section 12 and we will answer honestly rather than let you guess.

9. Changes to the Service

We may add, modify, or remove features at any time without notice. We may also discontinue the Service entirely. Calculator behavior can change between visits: because browsers cache our scripts aggressively for a year, you may be running an older version of the arithmetic than the one on the server for a short window after an update.

10. Changes to These Terms

When we update these terms, we post the new version here and update the "Last revised" date above. We do not send you an email about it — we have no mailing list and hold no email address for you, so continuing to use the Service after changes means you accept the new terms as published on this page. If a change is material, the only honest notice mechanism we have is the date on this page plus the entry in our internal audit ledger.

11. Governing Law

These Terms are governed by the laws of the State of Alaska, United States, without regard to its conflict-of-law rules. Any dispute that cannot be resolved informally will be brought exclusively in the state or federal courts located in Juneau, Alaska.

Worked Example: How One Request Flows

Four concrete paths through this Service, so the terms above are checkable rather than abstract. Steps 1–2 need no network at all; step 4 shows what a machine sees.

1. A calculation. Enter length 12 and width 12 on /square-footage-calculator/. Your browser multiplies them: 12 × 12 = 144 sq ft. No request leaves the page, because the multiply is in a script your browser already has.
2. A conversion. The same page converts 144 sq ft to square meters with the exact NIST factor: 144 × 0.09290304 = 13.37803776 m², displayed rounded to 13.38 m². Still zero requests. That is what section 2 means by "runs locally".
3. An ad request. Only if you click Accept: the page pulls the AdSense script from Google, and Google's ad request carries the usual signals (IP-derived general location, ad cookies). That is why section 7 points at the Cookie Policy instead of pretending ads are invisible.
4. A machine request. curl -H "Accept: text/markdown" https://footycalc.com/terms-of-service/ returns this page as Markdown; curl https://footycalc.com/.well-known/api-catalog returns the discovery linkset. Both are served without a key, which is why section 8 exists — access we grant openly should come with conditions we state openly.

Every one of those requests also passes through our hosting provider's edge, which is a separate party described in the Privacy Policy; these terms do not change what that party can log.

Sources and How to Check This Page

• IETF RFC 9309 — Robots Exclusion Protocol. The source for both quotations in section 8.3, including "These rules are not a form of access authorization." Check our /robots.txt against it to see that Content-Signal is outside that grammar.
• US Copyright Office — DMCA section 512 notice-and-takedown (.gov). The legal basis for the takedown route described on our contact page; we describe the statute, and we do not claim to be a registered designated agent.
• CalculatorSoup — Legal / terms. A published example of the carve-out we copied in structure: embedding widgets is licensed for commercial or non-commercial use even though site content is not. Compare with section 6.2.
• Inch Calculator — Terms of Use. A published example of an explicit AI-training refusal, and of a "personal use only" clause that is not reconciled with its own embed offer — the inconsistency section 6 is written to avoid.
• Our own files, which you can pull without permission: /auth.md (agent instructions, including the 503 on /agent-auth/*), /developers/embed-calculator/ (the widget license terms and its attribution requirement), and /js/calc-core.js (the arithmetic behind section 2 — check 144 × 0.09290304 yourself).
