The Story package is free. Each other package is a one-time purchase that unlocks all of its practices, including ones added later. There are no subscriptions; prices appear in Me → Practice packages.

Open Me → Practice packages and tap Restore purchases, signed in with the Apple Account you bought with. Purchases belong to that Apple Account, not to a Koucai account.

Tap your avatar on the Me tab to open App settings, then choose Practice language. The app’s own language is set separately under Display language. Each recording keeps the language it was made in.

Transcripts are made on your device. The first time you transcribe a language, iOS may need an internet connection to download its speech model, and some devices can’t transcribe every language. Your audio is saved either way; to try again, open the recording and tap Transcribe again.

Koucai has no account or sync. Your recordings move with an iCloud or computer backup, or with Quick Start when you set up a new iPhone or iPad. Check that they arrived before you erase the old device. Exported files are for keeping and listening elsewhere, and can’t be imported back.

Touch and hold a recording and choose Export recording to share its audio. To export your voice journals, open Me → Journal records and tap Export all recordings, or touch and hold a month to export just that month. Journal archives include titles and transcripts as text files.

Open Settings → Apps → Koucai on your device. The daily practice reminder and its time are in Koucai’s App settings.

Touch and hold a recording and choose Delete recording. To delete every recording, tap your avatar on the Me tab to open App settings, then choose Delete all recordings. Recordings are removed with their transcripts and titles; your profile, favorites and settings stay. Deleting the app removes all of its data. See the Privacy Policy.
