1. What Are Cookies & Local Storage?

Cookies are small text files that websites store on your computer, smartphone, or tablet when you visit a webpage. They enable websites to remember your device, preferences, and session state over time.

Browser Local Storage is a modern web standard that allows websites to store structured data directly on your device without sending that data across the internet with every network request. We use local storage to keep our calculators blazing fast and 100% private.

2. Categories of Cookies We Use

Helps us understand how visitors interact with our calculators by collecting anonymous aggregate data (page visits, bounce rates, device types) via Google Analytics 4.
