Safety and Privacy

A Promise Kept from the Start

Minor Protection and Guardian Consent

Protect minors and keep guardian consent from the start—handle sensitive information with care.

Default is 'Only me'

Learners choose the sharing scope themselves, and for minors the default is more conservative (not public and no real-name display).

Haru and Guardian Peace of Mind Assets

Like a quiet companion by your side

Haru’s reassuring expression, with towel and band accessories and a raindrop effect, directly conveys a sense of safety and care.

Privacy

You always decide who can see my records. By default, it’s set to “Only me.”

There’s nothing you get by luck. It’s exactly as much as the sweat you’ve shed.

Learn together

Start with pocket money—end without it.

Follow along

Parents and children follow each other’s learning. Both sides must accept to start, and each person progresses independently.

Learning Habit Bootstrapping

Start with allowance—end without it. It’s a program that helps your child study independently (about 12 weeks by default, tailored to your child’s pace).

If you graduate early, you can also choose to donate the remaining funds to another friend’s education.

How to Build Motivation

Pocket money is just a starter.

“If you study well, you get spending money” can push the fun out of studying if it’s designed the wrong way. SAUNA uses spending money only as a “starter,” and is designed so motivation shifts toward “money → meaning → learning becomes part of me.”

The child suggests first

Let your child suggest the goal and the allowance amount first, and you act as a negotiation partner. Feeling like they chose it themselves is the first step toward motivation.

Allowance decreases gradually

It starts with pocket money, but if you see them studying on their own, it gradually decreases. By graduation, they do it on their own without pocket money.

Specific praise

Not “Good job,” but more like, “You’ve perfectly mastered five phrasal verbs.” I’m your AI parent cheering coach.

Habits, one by one

Finish your vocabulary first, then grammar—don’t try to build multiple habits at once. That’s the fastest way.

Transparent Progress

We show the distance left to your current level and the next level in your parent dashboard in real time.

Rest is a right

We respect your choice to take a break this week. Rest isn’t a penalty—it’s what helps you go further.

Early Graduation Special Choice — Sharing

일찍 졸업하면 남은 비용을 크레딧·구독 대체·현금 환불·나눔 기부 중에 골라요. 나눔을 고르면, 기회가 없던 다른 아이가 우리 아이 덕분에 배우게 돼요 — "나 때문에 누군가 공부할 수 있게 됐다"는 뿌듯함은 돈으로 닿을 수 없는 깊이예요. (강요하지 않아요, 기본은 크레딧이에요.)

Please avoid this only

  • “You paid, so work harder,” they pressure—one sentence like that can collapse the design.
  • Setting goals unilaterally without discussing with your child — autonomy is lost.
  • “Make them donate the remaining money”—giving shines only when a child chooses it themselves.
The app shows virtual points, and the actual payout is up to your parents’ discretion. The child’s goals and reflection entries are private by default, so you can write honestly without feeling awkward.

Start with confidence, with your child

Parents watch from the side, while learners choose for themselves and continue on.
