About FYGIX

FYGIX publishes bilingual calculators designed to make methods, assumptions, limitations, and sources inspectable.

How the calculators are maintained

The FYGIX project maintainers implement and test the software. Formula versions, calculation fixtures, rounding policies, and source references are recorded with the calculator implementation.

A cited organization supplies a reference used by a calculator. Citation does not mean that organization built, reviewed, approved, or endorses FYGIX.

What review means here

Automated and manual checks cover calculation behavior, translations, accessibility, privacy boundaries, and deployment integrity. FYGIX does not claim independent, medical, financial, or legal accreditation.
