Privacy Policy
Your privacy is fundamental to our service. Read how Right Triangle Calculator safeguards user data, executes client-side computations, and manages technical analytics.
We operate with complete transparency: 100% of triangle calculations execute locally in your web browser with zero server data logging, no registration required, and total user data security.
Encrypted & Privacy-First Client-Side Execution Engine
1. Introduction & Core Principles
Welcome to Right Triangle Calculator (accessible via https://righttrianglecalculator.online). We are committed to protecting your online privacy. This Privacy Policy explains what information we collect, how it is used, and the steps we take to protect your data when visiting our website.
Key Privacy Guarantee: We do NOT require user accounts, passwords, email registration, or payment information to use any of our right triangle calculators or geometry guides.
2. Client-Side Mathematical Computation
All mathematical calculations performed on our website (including Pythagorean theorem evaluations, trigonometric inverse calculations, altitude, area, and perimeter calculations) execute entirely within your web browser using JavaScript.
The values you type into our calculator fields (leg lengths $a$, $b$, hypotenuse $c$, or acute angles $A$, $B$) are processed locally on your device. No mathematical inputs or calculation outputs are sent to, logged by, or stored on our web servers.
