On the Home screen, choose a subject, a question pack, then your child's favourite game. The “Continue” button takes them back to the most recent lesson.

Open the parent area via the “Parents” button to manage a separate profile for each child and view their learning progress.

Use Pack Studio on a computer (starjar.nsn-software.com/studio) and sign in with the same StarJar account as the app. Write at least 5 questions using the formats: choose text, choose image, listen then choose, fill in the blank, and speak English, then publish privately or share with a code/QR. In the app, go to the parent area → Library → enter the code to add the pack. Creating and sharing packs is always free.

In the parent area → Library, tap “Report content” on that pack, or email us with the share code. You can remove the pack from your device straight away; we will review and remove packs that break the rules.

Open StarJar Quiz on the App Store or tap the “Download iOS” button on the home page, then install the app on your iPhone or iPad.

Tap the “Download Android” button on the home page and follow the instructions on the download page to install the app.

Built-in question packs and some games are free. Neon Defender is a one-time purchase. “All games — monthly” (49,000 VND/month) is an auto-renewing Apple subscription on iPhone/iPad; on other platforms it is a 30-day PayOS pass that does not renew (buying again extends by 30 days). Purchases are only made in the parent area and require a signed-in parent account.

No. Sign in again with the parent account, then go to the parent area → Store → Restore purchases. Refunds are handled by Apple at reportaproblem.apple.com.

Go to the parent area → Settings → account → Delete account. All StarJar data on our servers will be deleted. See the privacy policy for details.

The forum, community accounts and sharing packs on the website are still being prepared. The community page will show “Coming soon” during this period.
