Under the map is “History”: where the child was and how they travelled, day by day; the arrows switch days. It is kept for 30 days; you can turn it off — then only the last location is kept. A stretch with no points (the phone was off or offline) is drawn dashed with “No data for N min”.
While the child stays in one place — at home, at school — the phone finds its position by Wi-Fi and cell towers, 100–200 m off, and the points jump a little. So that time is drawn as one spot, and the line only when the child really walks or rides.
The day's route and the 30-day history need the subscription. Without it the history area says “Available with the subscription”, and where the child is now is always shown.
