About CalcNote
**CalcNote: The Smart Notepad Calculator**
Turn your browser tab into a powerful, intelligent scratchpad that blends a text editor with a scientific calculator. CalcNote is designed for anyone who needs to crunch numbers without losing context—developers, students, freelancers, and quick planners.
Forget about switching between a calculator app and your notes. With CalcNote, you just type your math naturally, and the results appear instantly in the margin.
**🚀 Key Features:**
* **Live Evaluation:** Type `120 * 4 + 15` and see `495` appear instantly next to your line. No "Enter" key required.
* **Smart Variables:** Define values like `budget = 500` or `tax_rate = 0.2`, then use them later: `budget * tax_rate`.
* **Responsive & Dynamic:** Go back and edit a number in the first line, and every calculation that depends on it updates immediately.
* **Notepad Style:** Write comments, make lists, and mix text with math. Ideally suited for drafting invoices, estimating project costs, or solving homework.
* **Auto-Save:** Your work is saved automatically to your browser's local storage. Close the popup, restart Chrome—your notes are still there.
* **File Operations:** Save your calculations as a `.txt` file to your computer or load previous sessions with a click.
* **Scientific Power:** Supports standard arithmetic plus power (`^`), modulus (`%`), and constants like `pi` and `e`.
**📝 Example Usage:**
```text
Monthly Salary = 5000
Rent = 1200
Groceries = 450
Utilities = 150
Total Expenses = Rent + Groceries + Utilities
// Result: 1800
Savings = Monthly Salary - Total Expenses
// Result: 3200
```
**Why CalcNote?**
Traditional calculators are rigid. Spreadsheets are overkill. CalcNote hits the sweet spot—fast, flexible, and persistent.
**Privacy Policy:**
CalcNote operates entirely offline within your browser. It does not collect, store, or transmit any user data. Your calculations live only on your device.
