Piri coins are Piri's coins. The child gets them for accepted tasks, and you can “Give Piri coins” — what for and how many. The child has one jar for all their phones and tablets. “Tasks” → “Jar”: how many coins, the history (what came in and what was spent) and “Take off Piri coins” — e.g. when the child bought something as agreed: “Lollipop, 10”. The child sees it in their jar.
Did the coins arrive: under “Give” and in the history, coins given and tasks accepted show “Not on the phone yet”, “✓ Reached the phone” and “✓✓ Masha saw it” — when the child's “+10 Piri coins in the jar!” screen opened. “Saw it” comes from the child app 1.0.16 or newer; coins given before have no marks.
“Piri coins for time” (also in “Jar”): turn it on and choose the rate — e.g. “1 coin = 1 min” — and how many minutes a day can be bought. Below, “When the swap works”: “When the “Daily limit” is used up” (on from the start: the minutes go on today's limit), “When an app's time is used up” (minutes for that app today) and “During schedules” — each one separately: e.g. “School” yes, “Sleep” no (the schedule steps aside for the bought minutes, then applies again). During a break the swap never works: only you end a break. The child swaps coins themselves — on the block screen when that case is allowed, or in their “Jar”, which shows where the swap works. “At most per day” counts all cases together. If the swap would open nothing, no coins are taken.
“Extra time” — you can also offer an exchange for minutes in one app with a limit: how many coins and how many minutes.
