Terms of Service

These Terms of Service ("Terms") constitute a legally binding agreement made between you, whether personally or on behalf of an entity ("you", "user"), and Decimals Calculator ("we", "us", or "our"), concerning your access to and use of the website located at https://www.decimalscalculator.com and all associated tools, calculators, visualizers, and subdomains.

By accessing, browsing, testing, or performing calculations on Decimals Calculator, you confirm that:

• You have read, understood, and agreed to be bound by all of these Terms of Service;
• You have reviewed our Privacy Policy, which explains how we handle technical and client-side data;
• You possess the legal capacity to enter into these Terms (or have received proper parental/guardian or institutional permission if accessing as a minor).

If you do not agree with all of these terms, you are expressly prohibited from using the website and must discontinue use immediately.

Subject to your ongoing compliance with these Terms, Decimals Calculator grants you a non-exclusive, non-transferable, revocable, worldwide license to access and use our website and tools for:

• Personal Computation: Day-to-day decimal math, calculating ratios, unit conversions, financial tip breakdowns, and home improvement measurements.
• K-12 & Higher Education: Learning and teaching decimal place values, recurring decimal algebraic derivations, fraction simplifications (Greatest Common Divisor), and scientific notation.
• Professional & Technical Tasks: Performing decimal estimations, engineering tolerance checks, data set averages, and quick arithmetic within business workflows.
• Academic Citation: Researchers and educators may cite calculations, formulas, and visual demonstrations provided on Decimals Calculator in scholarly papers or curriculum materials with standard academic attribution.

Our engineering team implements rigorous algorithmic solutions—including custom fraction object representations, arbitrary-precision string math, BigInt arithmetic, and algebraic repeating decimal solvers—to counteract common IEEE-754 binary floating-point roundoff errors (such as the notorious 0.1 + 0.2 = 0.30000000000000004 artifact).

A. Our Proprietary Property

Unless otherwise indicated, the website, source code, visual design system, logos, illustrations, educational step-by-step algorithms, database schemas, and interactive visual components (including our Place Value Inspector, Algorithm Visualizer, and Exponent Visualizer) are our proprietary property and are protected by copyright, trademark, and unfair competition laws.

B. User Mathematical Content Ownership

We firmly believe that your mathematical inputs belong to you. We claim zero proprietary interest or ownership over the numbers, equations, formulas, or problem sets you enter into Decimals Calculator. You are free to copy, publish, publish-in-print, or distribute any results produced by our calculators.

Decimals Calculator operates as a client-side web application. When you execute an equation or conversion:

• Local Execution: Computation scripts execute in your web browser utilizing your device's CPU and memory.
• No Server Persistence: We do not receive, process on a remote cluster, or archive your mathematical inputs on our servers.
• User Device Responsibility: You are responsible for maintaining the security, compatibility, and updating of the browser, operating system, and hardware used to execute the calculators.
