When conflict, displacement or hardship interrupts school, children lose years that are hard to give back — and most learning tools assume an account, a paid plan and a steady connection.

One road through mathematics alone — school years first, then university-level courses and open problems — taught in the learner's own language, in the order and notation of their national curriculum. No sign-up, no ads, no personal data: it installs as an app, runs on a cheap phone, and works offline once downloaded.

A free, non-commercial school and academy in twelve languages — lessons, games and exercises that follow each country's published curriculum.
