Private by design

No ads, no trackers, no accounts. Everything stays on your device. We never collect or sell your family's data.

👨‍👩‍👧‍👦

A profile for each child with their own subject, difficulty, time limits and progress.

How it works

Three simple steps

1

Set it up once

Create your child's profile, pick their subject, choose the apps to lock, and set the difficulty and unlock time. Settings are protected by Face ID.

2

Kids learn to unlock

When your child wants their apps, their penguin guide gives them a short set of questions. Get enough right, earn the screen time.

3

Time's up, learning's back

When the timer ends, apps re‑lock automatically. A quick new challenge unlocks them again. Practice becomes a daily habit.
