Safety and privacy, said plainly
What Helio keeps, what it never does, and what you control.
What Helio keeps
Only what the lesson needs, and only once a parent agrees.
Voice
Turned into text. The sound is not saved.
Words
What your child says, to follow the lesson.
Board
What your child writes, to check the work.
Progress
What your child has learned, to plan what is next.
Before the first lesson
A parent says yes
Under 13, nothing starts until a parent agrees.
No email needed
Children sign in with a code and secret words.
Or a school says yes
A school can give permission for its own students.
During a lesson
Helio stays on the lesson, and you can see how it went.
Safe content
Both sides of every chat are checked for unsafe content.
You see what matters
Anything worrying shows on your child's page, with a replay.
Every step checked
Every math step is checked, Helio's and your child's.
You stay in control
Change any of it from your child's page, any time.
Download or delete
Get a copy of your child's data, or delete the account, any time.
Take back your yes
Withdraw permission at any time.
A daily limit
From 15 minutes to 2 hours a day, within your plan.
What Helio never does
No ads, no streaks
No points or leaderboards, and your child's data is not sold.
No training on kids
Your child's data does not train AI unless you allow it.
Honest about AI
It can be wrong
Math is checked. In other subjects, ask why.
A computer voice
Helio's voice is made by a computer, and it says so.
For schools
Student data is used only for the school. Small groups stay hidden in reports.
