Terms of Service
Plain-Language Summary (TL;DR)
You are completely welcome to use Area of Circle Calculator for personal, classroom, educational, engineering, and commercial calculations free of charge. Our calculations run 100% locally on your device with high-precision mathematics. However, while our equations are rigorously proven, they are provided for educational and analytical purposes — you must independently verify all measurements with certified professional engineers prior to physical construction or safety-critical fabrication.
1. Acceptance of Terms
By accessing, browsing, linking to, or otherwise utilizing Area of Circle Calculator (accessible at https://www.areaofcirclecalculator.com and associated subpaths, collectively the “Service” or “Site”), you acknowledge that you have read, understood, and agree to be legally bound by these Terms of Service (“Terms”) and our associated Privacy Policy.
If you do not agree with any provision set forth in these Terms, your sole remedy is to immediately discontinue access and use of the Service. These Terms apply to all visitors, registered users (if any), students, professionals, and all third parties accessing our computational tools.
2. Permitted Use & License Grant
Subject to continuous compliance with these Terms, Area of Circle Calculator Ltd. grants you a personal, non-exclusive, non-transferable, revocable, worldwide, royalty-free license to access and interact with our web applications, interactive visualizers, mathematical reference tables, and educational explanations.
- Perform unlimited personal, academic, scientific, and commercial calculations.
- Incorporate calculated outputs and formulas into homework solutions, academic papers, research publications, and engineering notes with appropriate citation.
- Display or demonstrate the calculators in classrooms, lectures, webinars, and educational seminars.
- Copy and export derived tables, dimensions, and conversion values for architectural drafts, cost estimations, and trade estimates.
3. Professional & Structural Engineering Disclaimer
PLEASE READ THIS SECTION WITH HEIGHTENED SCRUTINY BEFORE UTILIZING COMPUTATIONS FOR PHYSICAL WORK:
While Area of Circle Calculator implements rigorous double-precision arithmetic (Math.PI ≈ 3.141592653589793), Base-SI normalization, and strict geometric boundary algorithms, all tools, formulas, graphs, tables, and guides are provided solely for educational, analytical, and preliminary planning purposes.
Calculations provided by the Service do not constitute certified engineering advice, architectural blueprints, structural load certifications, pressure vessel ratings, or safety-critical recommendations. Real-world physical systems involve material tolerances, thermal expansion, weld factors, fluid viscosity, shear stress, and environmental load factors that cannot be captured by pure geometric area equations alone.
Prior to purchasing structural materials, pouring concrete caissons, boring pipeline channels, milling aerospace alloys, or executing any safety-critical build, you are strictly obligated to have all specifications, dimensions, and safety tolerances independently calculated, reviewed, and stamped by a licensed Professional Engineer (PE) or registered architect.
4. Mathematical Accuracy & “As Is” Warranty
The Service and all associated contents are provided strictly on an “AS IS” and “AS AVAILABLE” basis without warranty of any kind, whether express, statutory, or implied.
To the maximum extent permitted under applicable law, Area of Circle Calculator Ltd. expressly disclaims all warranties, including but not limited to the implied warranties of merchantability, fitness for a particular purpose, non-infringement, quiet enjoyment, and any warranties arising out of course of dealing or trade usage. We do not warrant that results will be uninterrupted, error-free, immune to browser script anomalies, or compatible with every legacy mobile operating system.
5. Intellectual Property & Public Domain Geometry
Our Proprietary Materials: The unique design architecture, custom responsive layouts, interactive SVG canvas logic, branding, custom typography pairings, bespoke CSS, software source code, and original pedagogical articles on this website are the intellectual property of Area of Circle Calculator Ltd. and are protected by international copyright, trademark, and trade dress regulations.
Public Domain Mathematics: Universal geometric theorems, algebraic identities (e.g. A = πr², A = (πd²)/4, C = 2πr), and fundamental mathematical constants (π) are inherent properties of mathematics belonging to the public domain and are not claimed as proprietary.
6. Prohibited Activities
When accessing our Service, you expressly agree not to engage in:
- Malicious Automation & Scraping: Using automated bots, web scrapers, spiders, or harvesting tools to extract site assets, reproduce whole pages, or artificially overload our hosting network.
- Denial of Service Attacks: Launching Distributed Denial of Service (DDoS) attacks or intentionally flooding our edge servers with spurious HTTP requests.
- Malware & Exploit Injection: Introducing viruses, trojans, worms, logic bombs, or other technologically harmful payloads.
- Impersonation: Misrepresenting your identity, pretending to represent Area of Circle Calculator Ltd., or framing the Service inside third-party iframe containers without explicit attribution.
7. Limitation of Liability
In no event shall Area of Circle Calculator Ltd., its directors, employees, affiliates, contributors, or technology licensors be held liable for any direct, indirect, incidental, special, consequential, exemplary, or punitive damages of any nature whatsoever — including, without limitation, damages for loss of profits, construction delays, material waste, engineering defects, equipment downtime, loss of data, or commercial injury — resulting from:
- Your access to, use of, or inability to access or use the calculation utilities;
- Any errors, omissions, or mathematical discrepancies within the calculators, educational texts, or conversion charts;
- Reliance placed upon any mathematical output, formula breakdown, or unit conversion;
- Any unauthorized access to, alteration of, or security events impacting our infrastructure.
8. Indemnification
You agree to defend, indemnify, and hold harmless Area of Circle Calculator Ltd., its officers, directors, contractors, agents, and contributors against any and all claims, liabilities, damages, losses, costs, and expenses (including reasonable attorney fees) arising out of or in connection with: (a) your use of or reliance on calculations obtained from the Service; (b) your violation of these Terms; or (c) your violation of any rights of a third party in connection with your work.
9. Modifications to Service & Terms
We reserve the right, at our sole discretion, to modify, update, replace, or temporarily discontinue any portion of the Service or these Terms at any time without prior individual notice. When updates occur, we will revise the “Last Updated” timestamp at the top of this document.
Your continued use of the Service following the publication of any revised Terms constitutes your unconditional agreement to be bound by the updated stipulations.
10. Governing Law & Severability
These Terms and any dispute or claim arising out of or related to them shall be governed by and construed in accordance with generally recognized principles of international commercial and contract law, without giving effect to any choice or conflict of law principles.
If any individual provision of these Terms is determined by a court of competent jurisdiction to be invalid, illegal, or unenforceable, that specific provision shall be limited or eliminated to the minimum extent necessary, and the remaining provisions shall remain in full force and effect.
