About
This is a provisional page: the site currently offers no paid products, so no specified-commercial-transactions disclosure is legally required yet. A dedicated disclosure page will be added before any paid ("Pro") feature launches.

Our approach
This Service converts official primary sources into deterministic calculations with a confirmed verification date. Every figure links back to its government or official source; no AI-generated guesses are used in calculations.
