The Digital Twin is a private learning profile. It starts empty, fills in from your child's own lessons, and decides what Jero teaches next and how.

Most learning apps track five to ten numbers, like scores and streaks. The Twin keeps 50 to 75, so it can say something useful: “ready for two-step problems, remembers best with spaced practice, keeps going longer on real-world problems.”
Sample Twin for an 8-year-old scholar.
The concept and the standard stay the same for everyone. How your child meets it changes.
Set at the edge of what your child can do, and moved after each answer.
Football scores, animals or building blocks, depending on what keeps them going.
Guided steps first, or straight to the challenge.
Objects, pictures or puzzles, chosen by what your child still remembers a week later.

The Twin is never sold and never used for advertising.
It decides the next lesson. It is never used to rank children or label them.
You can see it, download it and delete it from your portal.
Stored in your family's data region, under the privacy law where you live.
