Hanzi Helper is a Chinese reading-aid app that adds pinyin transcription to words you select in a text. Your privacy is important to us, and the app has been designed with a simple principle: your data stays on your device.
Hanzi Helper does not collect, transmit, or store any personal information. Specifically:
We do not collect names, email addresses, or other identifying information. We do not track your location. We do not use analytics or advertising frameworks. We do not transmit any data from the app to external servers. All texts, word lists, and settings you create are stored locally on your device and are not accessible to us.
Hanzi Helper does not integrate any third-party analytics, advertising, or tracking services.
All content you add to Hanzi Helper — texts, pinyin annotations, word lists, and preferences — is stored locally on your device. If you delete the app, this data is removed.
Because Hanzi Helper does not collect any personal data, it is safe for users of all ages.
