Idiom Sprout: Chinese Stories

Chinese Idioms is a focused learning app for children ages 6–8 who are beginning to explore Chinese language and literacy. Children first hear clear Mandarin pronunciation, then learn through character ordering, missing-character choices, meaning choices, usage checks, and listening questions. Sessions are short and have no countdowns, lives, leaderboards, or streak pressure. A simple explanation follows a mistake, and the idiom returns for review at an appropriate time. The first release includes 210 carefully prepared four-character chengyu: - Learn the first 3 chengyu in full for free - Unlock the remaining on-device content with one permanent purchase - No subscription and no advertising - Price and purchase options appear only after a parent completes the parent check Designed with children’s privacy in mind: - No registration or sign-in - No requests for camera, photos, microphone, location, contacts, or tracking access - No advertising or third-party analytics SDK - Progress, mistakes, and favorites stay on the device - Chinese pronunciation uses Apple’s on-device speech synthesis Core learning remains available offline. After a parent completes the parent check, the optional Learning Playground uses the fixed China storefront to request public App Store information and HTTPS icons from Apple. It displays only same-developer App IDs on a manually reviewed allowlist, does not read or send the device region, and sends no learning records, children’s information, account details, or advertising identifier. The returned public catalog information is cached on the device. Opening a selected app’s App Store page requires a new parent check before leaving the app. In the Parent Center, adults can choose the daily number of new chengyu, control pinyin, speech, sounds, and haptics, read the terms and privacy notices, restore a purchase, or reset on-device learning data. The 200 added chengyu currently use Chinese explanations, examples, and feedback in every interface language. The original 10 retain their translated learning text.
