Frequently asked questions

Is LumaCard free?

Yes. v1.0 is free with no advertising and no in-app purchases. We may add optional content packs in future versions; the existing free content will stay free.

Does it work offline?

Yes — everything works without a network connection. All audio, character data, and vocabulary cards are bundled inside the app.

What languages does it support?

The app's interface is available in Traditional Chinese (zh-Hant) and English (en). The learning content covers three languages side-by-side:

Japanese UI translation is planned for v1.1.

What age range is LumaCard for?

Designed for ages 4–9. Younger kids will enjoy the tracing and stickers; older kids will move on to vocabulary cards and word puzzles.

Can multiple children share one device?

Yes. Tap the profile chip on the home screen to add a new learner. Each child has their own progress, sticker collection, and Leitner review schedule.

How do I reset my child's progress?

Settings → Reset Progress. You can reset a single deck (e.g. just the Zhuyin tracing) or reset all vocabulary progress. Profiles themselves are managed under Settings → Profiles.

Why is there a math problem when I tap a link in Settings?

That's the parent-verification gate. Apple's "Made for Kids" guidelines require a simple gate before any link that leaves the app (privacy policy, contact email). It protects your child from accidentally tapping out. Adults solve it in two seconds; small kids generally can't yet.

How do daily reminders work?

If you opt in (Settings → Notifications), LumaCard schedules a single local reminder at the time you pick. There's no push server involved — everything is on-device. Disable any time in iOS Settings → Notifications → LumaCard.

I think there's a bug. What should I include in the email?

Helpful details:

Will there be new content?

Yes. The current 600 vocab cards and 181 traceable characters are v1.0. We're already planning more themes for v1.1+. Email us if there's a specific topic your child wants — we read every request.

Where can I read the privacy policy?

Right here. TL;DR: we collect nothing.
