âī¸ Technology
CalculateIA is built with pure HTML, CSS and JavaScript â no frameworks, no build tools, no external libraries. This keeps the site fast, lightweight and fully offline-capable.
Our Natural Language Date Parser is a highlight feature. It's a fully rule-based engine that understands date inputs like "next friday", "15 aug 1990", "in 2 weeks", or "q3 end" â with zero AI API calls and zero dependencies. It handles ambiguous formats, generates alternative suggestions, and visualizes tokens with colour-coded pills.
đ Privacy
We take privacy seriously. CalculateIA operates entirely client-side â no input values, personal data, or calculation results are ever transmitted to any server. We do not use cookies, analytics trackers, or third-party scripts of any kind.
The only external resource loaded is the Google Fonts stylesheet for typography. All calculator logic, parsing and rendering happens on your device.
