# About BQ Calculator

BQ Calculator is a BQTools utility property focused on fast answers, transparent formulas and calm professional interfaces.

## Calculator first

Every dedicated calculator page puts the interactive calculator before long explanations. Supporting content exists to clarify formulas, units, assumptions and limitations—not to pad pages with decorative copy.

## Local by design

Calculator inputs are processed in JavaScript in your browser. No account or external calculation API is required. Optional recent history is stored in localStorage on your device.

## Zero calculator dependencies

The calculator interface uses HTML, CSS, vanilla JavaScript, native Canvas and browser APIs without a framework, external font or chart library. Google Analytics is optional and loads only after analytics consent.

## Quality before quantity

We prefer a smaller set of complete calculators over many thin variants. A calculator must have a distinct purpose, working logic, useful documentation and quality checks before it is published.

## Scenario comparison and export

Calculator pages can compare up to three local scenarios, restore prior inputs, export current inputs and results as CSV, copy formulas and surface a compact live result dock on smaller screens. Favorites and recent-tool shortcuts make repeat calculations faster without requiring an account.
