Privacy Policy

Last updated · 2026-07-02

TL;DR

There's no sign-up, and your coloring and gallery data stays on your device in your browser's localStorage. We do run Google AdSense ads and a visit-stats tool to support the site, which may set their own cookies — see 'Third-party services' below for details.

What we don't collect

Names, emails, phone numbers — no identifiers
Location, device IDs, advertising IDs
User accounts — there's no sign-up

What lives in your browser

These items are stored in your browser's localStorage only. They never leave your device. You can clear them anytime from your browser settings.

Your language preference (Korean / English)
Whether sound is on or off
Your gallery of completed storybooks (up to 12, cover image + metadata)

Browser features we use

Web Audio API — sound effects are generated in your browser (no audio files downloaded)
Web Speech API — used to pronounce Korean words. Your browser handles this locally; we don't transmit the text
Web Share API — used when you share a completed storybook. You choose where to share

Third-party services

We show ads via Google AdSense to help cover hosting costs, and use Vercel Analytics to see basic visit statistics. Both may use cookies or similar technologies for ad personalization or usage analysis.

You can learn how Google uses ad data at Google's Ads Privacy page, and manage or opt out of personalized ads at google.com/settings/ads.

Children's privacy

This site is designed to be safe for children. Because we don't collect anything, we cannot knowingly or unknowingly collect personal information from children under 13.
