Mini Calculator (Simple)

A simple mini calculator in the popup (offline).

Mini Calculator (Simple) is a lightweight Chrome extension built for one purpose: giving you a clean, fast calculator inside the extension popup. Open the popup and quickly calculate everyday math such as addition, subtraction, multiplication, division, and percentages—without opening a separate app or leaving your current page. The interface is intentionally minimal and easy to use, with both button input and keyboard support (numbers, operators, Enter, Backspace, and Esc). The extension works fully offline, requests no permissions, and does not collect or transmit any data. All calculations are performed locally in your browser.
