Privacy Policy

Updated September 23, 2026

1. Our commitment to your privacy

At HanziCue, we believe that your personal data belongs to you. The app helps you learn Mandarin with a course, reviews and widgets, and lets you study your own Chinese and Japanese decks, without compromising your privacy. We do not collect, store, track or share any of your personal information.

2. No server-side collection

We do not run backend databases or registration systems that log your activity. You do not need to create an account or sign in to use HanziCue. HanziCue contains no analytics or advertising.

3. Data stored on your device

Your course progress, voice recordings, imported Anki packages (.apkg) and CSV lists, settings and review history are stored locally in the app's storage and in a shared App Group container, which lets widgets show your cards. HanziCue does not sync this data through iCloud or any server. If you create a backup file, you choose where it is saved.

4. Microphone, recordings and tone checking

With your permission, HanziCue uses the microphone to record your spoken practice. Recordings are saved on your iPhone so you can listen back, and you can delete them. Check my tones analyzes the pitch of a recording entirely on your iPhone and keeps only a temporary file while the check is open.

If you allow speech recognition, HanziCue can transcribe a recording using Apple's on-device speech recognition only. If on-device recognition is unavailable, HanziCue does not send your recording anywhere.

5. In-app purchases

Purchases of HanziCue Pro (monthly subscription or lifetime) are processed by Apple through StoreKit. We do not have access to your payment methods or billing information. Apple provides only the purchase status needed to confirm your access.

6. Text-to-speech

Mandarin audio is produced on your iPhone with the voices installed in iOS. No text or audio is sent to third-party servers for this.

7. Changes to this policy

We may update this policy from time to time. Because we do not collect contact details, please review this page periodically. Updates are effective when posted.
