Before the first message the adult and the child accept the chat rules. There are quick replies (“Where are you?”, “I'm home”, “All good”), and the child can send a photo or a voice recording. Messages are kept for 30 days. The child can hide an upsetting message, report it or turn messages off — you'll see that the chat is off.
Your messages carry ticks, as in messengers: ✓ — the message reached the child's phone, ✓✓ — the child saw it (the chat was open on their screen). The same on the child's side: ✓ — their message reached you, ✓✓ — one of the adults saw it. Messages sent before the ticks existed have none. A message the child hid on their phone never becomes “seen”. If the child must see it at once, call from KidPair.
