Privacy

Last updated: 12 September 2026

The short version

Our apps are built for children, so they collect nothing. No accounts, no ads, no analytics, no third-party trackers, and no advertising identifiers. Your child's progress never leaves the device.

What stays on the device

• Practice history, stars, mistakes and review schedules (stored in the browser's local storage).
• Child profiles and settings created inside the apps.
• Phonics reading progress and earned stickers.

The Olympiad Practice Hall can export this data to a JSON file you control, so you can back it up or move it to another device yourself. Exporting is manual and only happens when you press the export button.

What we never do

• We do not ask for names, email addresses, phone numbers or any sign-up.
• We do not run analytics or embed third-party scripts on this site.
• We do not sell, share or transfer any data, because we never collect any.
• We do not show ads or track your child across other apps and websites.

Offline use

Both apps work offline once loaded. While offline, nothing is sent anywhere because the apps make no network calls for their content or your child's activity.
