Precision Arithmetic Guarantees

At CalcOS, we believe calculations are only useful when they are 100% correct. We build dynamic calculators designed to help you make decisions.

Our Verification Methodology

Every equation integrated into the CalcOS engine undergoes a multi-step verification process to ensure absolute mathematical compliance:

1. Formula Verification

Formulas are sourced from peer-reviewed financial, health, and engineering standards (e.g. World Health Organization BMI thresholds).

2. Unit Testing

Every engine module undergoes automated verification using Jest, asserting outcomes against pre-calculated standard reference points.

3. Sandbox Execution

Our tokenized recursive-descent math parser isolates user input parsing, avoiding unsafe browser runtime scripts.

Open-Source & Privacy Standard

CalcOS runs entirely client-side for dynamic calculation equations. Your financial parameters, health statistics, and measurement details are processed on your device. We respect browser **Do Not Track** parameters and prioritize data protection.
