Privacy Policy

1. About CalculatorDigital & Controller Identity

CalculatorDigital ("we," "our," "us") is a digital computational resource developed and maintained by Chandan Yadav, reachable at calculatordigital.in. This Privacy Policy details our procedures regarding the collection, use, protection, and disclosure of technical and analytical data when you use our online calculation tools.

By accessing or using CalculatorDigital, you acknowledge that you have read and agree to the practices outlined herein. If you do not agree, please discontinue using our website.

2. Client-Side Calculation — Complete Data Isolation

The foundational engineering principle of CalculatorDigital is zero server transmission of computation parameters. All calculation formulas execute strictly within your local browser JavaScript environment. When you enter financial figures (such as loan amounts, salary, savings balances), anthropometric measurements (height, weight, body fat), or mathematical values:

• Your input data is never transmitted across the internet to our web servers or backend cloud instances.
• Your data is never recorded in any server-side database, telemetry cache, or access log.
• Input numbers exist purely in volatile device memory and are destroyed when you close or refresh the web page.
• Optional calculation history features store records exclusively in your browser's localStorage, which never leaves your physical device.

3. Automatically Collected Technical Information

To maintain network security, ensure cross-browser compatibility, and monitor uptime, our web server software automatically records standard non-identifying server logs:
