# CalcWise.org - Extended LLM Notes

## Overview
CalcWise is a privacy-first, open source calculator library built by a solo developer (Aaron Jegla). The site focuses on speed, clarity, and respectful UX. All calculations run client-side in the user browser. No calculation inputs or results are collected or stored.

## Core Principles
- Privacy-first: no data collection from calculator inputs.
- Transparent and honest: clear assumptions and limitations.
- Fast and lightweight: minimal JS, strong Core Web Vitals.
- Open source: code and formulas are public.

## Content Structure
- Home: calculator search + top categories + popular tools + Learn highlights.
- Calculators: category pages and individual calculator pages.
- Learn: blog posts, guides, and explainers that funnel to calculators.

## Categories (example set)
- Finance
- Health
- Math
- Conversions
- Business
- Science

## SEO and Linking
- Use extensionless, canonical URLs only (no .html).
- Prefer internal linking from Learn articles to calculators.
- Use structured data where applicable (WebSite + SearchAction).

## Analytics
- Plausible only (cookieless).
- Ads are served via Google AdSense; consent banners may appear in regions where required.

## Policies
- Calculators provide estimates and are not professional advice.
- No accounts, no paywalls, no tracking of calculation inputs.
