Frequently asked
Quick answers. Email hello@lumikids.dev if you don't see yours.
What ages is Lumi for?
K–3 — kindergarten through third grade. Phase 1 is optimized for Level 5 (roughly mid-kindergarten through early first grade).
Does my child need to read to use Lumi?
No. Lumi speaks every instruction. Every interactive element has audio-on-hover or audio-on-mount so a child who cannot read yet can navigate Lumi unaided.
How long should a session be?
5–8 minutes is ideal. Lumi gracefully wraps a session at 8 minutes (when it finds a good stopping point) and hard-caps at 15 minutes. Most reading research shows shorter, daily sessions out-perform long weekly ones.
Is Lumi really free?
Yes. We may offer paid school licenses later, but the family product stays free.
Why is Lumi free?
Founder cross-subsidy from Digital Boutique AI plus future school-license revenue funds the family product. More on our funding model.
What devices does Lumi work on?
Any modern web browser — desktop Chrome, Safari, Firefox; iPad Safari; Android Chrome. Best experience is on iPad held in landscape. A native iPad app is on the roadmap for a later phase.
Will Lumi replace my child's school reading instruction?
No. Lumi is a supplement, not a curriculum replacement. A great reading teacher in a great classroom is still essential.
Does Lumi work for kids with dyslexia, ADHD, or learning differences?
Many users with these profiles use Lumi successfully — the voice-first design, large touch targets, and adaptive pacing all help. That said, Lumi is not a diagnostic tool; see a qualified specialist if you suspect a learning difference. Phase 6 will add explicit modes (e.g. OpenDyslexic font toggle, slower-default-pace).
What about Spanish or other languages?
English-first in Phase 1. Spanish curriculum is planned for Phase 6.
Why is there no microphone in Phase 1?
Speech recognition for under-7 voices is still unreliable. We'd rather ship no microphone than a frustrating microphone that mis-hears your child and demotivates them. Phase 2 adds microphone for fluency tasks with SpeechAce or ElevenLabs Scribe.
How is Lumi different from Lexia, Reading Eggs, or Khan Academy Kids?
See the comparison on the homepage. Short version: Lumi is faster (≤1.2s first-sound P50), free, has an actually-adaptive AI tutor, and remembers your child across sessions.
How does Lumi protect my child's data?
The full posture is at /compliance: COPPA-compliant, no ads, no AI training on child data, no data resale, single source of truth on which sub-processor sees what, full retention schedule.
Can I delete my child's data?
Yes — one click in the parent dashboard under "Data." Hard-deletes everything within seconds; a 7-year audit record (parent ID + timestamp, no child data) is retained per legal requirement.
