Cinqic Software / 01
Cinqic Calculator
A lightweight, private desktop calculator for Windows. Perform standard and scientific calculations, convert common units, review local calculation history, and use practical financial tools — without an account, cloud service, or internet connection.
Windows 10/11 · 64-bit · Version 1.0.1
01 — Overview
Useful without an account, and without AI.
Cinqic Calculator is Cinqic’s first small public software product — a genuinely useful desktop tool built around the same principle that will guide the rest of Cinqic’s software: AI should remain a choice.
Unit conversion
Length, mass, temperature, area, volume, speed, time, and data storage — decimal and binary units kept distinct.
Financial tools
Discounts, sales tax, tips, bill splitting, and simple & compound interest estimates.
Local history
Recent calculations stay on your device, with an easy way to disable or clear them.

Juniper relationship
Built for the future Juniper ecosystem.
Cinqic Calculator works entirely without artificial intelligence. Juniper is not integrated into Cinqic Calculator 1.0. Future versions may add optional local Juniper explanations while the calculator keeps working fully offline without AI. AI should remain a choice.
