Privacy Policy
Koucai is a retelling practice and voice journal app for iPhone and iPad, published by Wende Li. This policy covers the app, this website and support email.
On your device
Local data
Koucai keeps your recordings, their titles and transcripts, and your corrections on your device, with each recording’s date, duration and language. It also keeps your display name, profile photo, favorites, settings and a random identifier for your local library.
The app has no account or server and sends none of this to us. It has no advertising, tracking or third-party analytics. This applies to everyone, including children.
Microphone and speech
Koucai asks for microphone access to record retellings and voice journals. A recording in progress continues if you switch apps or lock your device.
Apple’s speech recognition transcribes recordings on your device; the audio is not uploaded. A language’s first transcription may download its speech model, and support varies by device and language. Listen reads passages aloud with your device’s speech voices.
Photos and reminders
The system photo picker shares only the photo you choose. Koucai keeps a small copy without its location or other metadata.
Daily practice reminder asks for notification permission when you turn it on and schedules reminders on your device. Once you save a recording, that day’s reminder is skipped. No server is involved.
Managing your data
Backups and exports
Depending on your device settings, Koucai’s data may be included in iCloud or computer backups and in transfers to a new device. Koucai has no sync or backup service of its own.
You choose where to save or share an export. A single recording exports as audio; journal archives also include titles and transcripts as text files, where present. The app or service that receives a copy handles it, and exports cannot be imported back into Koucai.
Deleting data
Touch and hold a recording and choose Delete recording to remove its audio, title and transcript. To delete every recording, tap your avatar in Me to open App settings, then choose Delete all recordings. Your profile, favorites and settings remain; you can change your name or remove your photo in Profile.
Deleting the app removes its local data; offloading it keeps the data. Existing backups and exported copies stay where they are stored and must be managed separately.
Apple and other services
Purchases
Apple processes App Store payments; we never receive your payment details. Koucai checks your App Store purchases to unlock the packages you own. Apple may provide us with purchase reports that do not identify you. See App Store & Privacy.
Diagnostics
Koucai records operational errors in your device’s system log, without audio or personal text, and uses no third-party crash reporting. If you choose to share analytics with app developers in your device settings, Apple may provide aggregated or non-identifying crash and usage information. See App Analytics & Privacy.
