No. The app is free, with no in-app purchases, subscriptions, or ads.
Yes — translation runs on your device. By default the app uses a neural engine bundled with the app. If that engine is turned off or unavailable, it falls back to the on-device dictionary. Your source text and translations are not sent to our servers. A network connection is used for the daily weather sentence, for downloading on-device speech models the first time, and for opening the in-app Privacy Policy or Support pages (the first two talk only to Apple).
My words, translation history, and learning stats stay only on this device. You can clear them with “Reset all data” in Settings, or by deleting the app.
Location is used only to pick the city for today’s weather sentence (When In Use, one-shot, about kilometre accuracy, no background tracking). If you deny location, the app uses the fallback city in Settings. You can turn off “Show weather sentence” in Settings, or revoke location access in iOS Settings. Weather comes from Apple WeatherKit and is requested from Apple, not from us.
No. Recognition always runs on the device. The first time you use it, the app may need to download Chinese and English on-device speech models from Apple (that step needs a network connection). After that, it works offline.
No. The photo is used only to recognize Chinese or English on the device and fill the translation box. It is not saved to your library and is not uploaded.
Open Settings (the gear in the corner) and choose “Reset all data”. This permanently clears saved words, history, and progress on this device.
Some meanings come from the bundled CC-CEDICT dictionary (CC BY-SA 4.0).
