Whether the phone can be used right now, “Ask for time” (only when time is short; during a break — “Ask to end the break”), the lesson now, a task, “I'm OK” (the family gets a message and the location), “Write to family”, “Call family”, and further down “What adults see”, “Where I am” and “My rules”.
Before a break, a schedule or the end of the day's time the child sees a warning in advance — a banner over the game and a notification, to save and finish. Calling and texting work during a break too.
