What Chunja is

Chunja is an educational app for studying the 千字文 (Thousand Character Classic), a classical four-character primer composed in 6th-century China and widely used in Korea and Japan to learn traditional Chinese characters. The app presents the original 250 four-character stanzas along with Korean readings and meanings, and offers a sequence-respecting spaced-repetition mode for memorization.

Scholarly nature, not authoritative reference

Translations, glosses, and readings shown in Chunja are drawn from public-domain sources (notably Korean Wikisource: 번역:천자문). They are provided for study and personal reference. Chunja is not a peer-reviewed scholarly edition. Do not cite it as a primary academic source without verifying against the source texts.

Pricing

Chunja is free to download and use. There are no subscriptions, no in-app purchases, and no advertising.

Acceptable use

You may use Chunja for personal study. You may not redistribute the app's bundled study content as a derivative product, decompile or reverse-engineer the app, or attempt to misrepresent the app as your own work.

License

Chunja grants you a personal, non-transferable, non-exclusive license to use the app on your Apple devices in accordance with the Apple Media Services Terms.

No warranty

Chunja is provided "as is" without warranties of any kind. The author is not liable for any losses or damages arising from the use of, or inability to use, the app.

Changes to these terms

We may update these terms over time. Continued use of Chunja after an update means you accept the revised version.

Governing law

These terms are governed by the laws of the Republic of Korea, without regard to conflict-of-law principles. Apple's standard EULA also applies to your use of the app as a licensed application from the App Store.
