Terms of Service & Computational Charter

1. Informational, Scoping & Preliminary Planning Purpose Only

Homecalpro operates as a free, universal online calculation hub providing standardized computational tools across personal finance, residential construction, structural framing, mathematics, business economics, and daily utilities.

All calculation outputs, formulas, amortization schedules, and unit yields are provided for preliminary scoping, educational comparison, and retail budgeting purposes only. While our algorithms are calibrated against recognized engineering and financial benchmarks, digital calculations cannot substitute for physical on-site inspections by licensed professional engineers, certified public accountants, licensed building contractors, or registered architects.

2. Zero-Hallucination Deterministic Math Policy

Homecalpro formally discloses that all 240 master calculation engines on this platform are programmed in deterministic, client-side TypeScript code verified by an automated test suite containing 340+ unit tests.

We formally disclose that no numerical output is generated by or routed through generative Large Language Models (LLMs) or statistical AI at runtime. Calculations execute deterministically within your browser's local memory engine, calibrated to standards published by:

• The National Institute of Standards and Technology (NIST) for unit conversions.
• The International Residential Code (IRC) and International Building Code (IBC) for architectural geometry and structural spans.
• The American Concrete Institute (ACI) and ASTM International for volumetric material densities and compaction yields.
• Federal Truth in Lending Act (TILA) guidelines and the Federal Reserve for financial amortization compounding.

3. Mandatory Human Editorial Review & Metadata Oversight

In strict compliance with official Google Search Central Helpful Content Guidelines, Google Search Quality Evaluator Guidelines (E-E-A-T), and Google's Guidance About AI-Generated Content:

• All articles, mathematical proofs, worked scenarios, and table figures on Homecalpro are authored, fact-checked, and reviewed by human technical specialists.
• All search metadata—including title tags, meta descriptions, image descriptions, and Schema.org structured data—is reviewed by humans to prevent automated metadata hallucinations, keyword manipulation, and misleading search snippets.
• Homecalpro does not employ synthetic AI author personas, fictitious headshots, or fake biographies. Content is governed by institutional accountability under the Homecalpro Engineering & Standards Board and founder Deepak Kumar (M.Pharm).

• Deploy automated bots, scrapers, headless crawlers, or harvesting tools to extract calculator formulas, tabular datasets, or editorial text without our express prior written permission.
• Engage in scaled content abuse or automated programmatic syndication by republishing Homecalpro calculation logic into doorway pages or low-value MFA (made-for-advertising) networks.
• Frame, mirror, or repackage any portion of Homecalpro within an iframe or third-party commercial application without attribution and explicit written licensing.
