The iPhone app is available on the App Store.

Do I need an account or a subscription?

Local study does not require a separate app account. Compatible builds offer optional iCloud review synchronization in Settings. Paid access can be required after the introduction. The app shows the available purchase options before you buy. Apple manages App Store purchases and subscriptions.

How does the lock-screen word work?

A single Chinese character waits on your lock screen. You meet it every time you reach for your phone, before the scroll begins. Add the widget from your iPhone's lock-screen editor: press and hold the lock screen, tap Customize, choose Lock Screen, tap a widget slot, and pick Lock In Chinese. The word refreshes on a spaced-repetition schedule tuned to how you answer.

How does the Screen Time seal and quiz-unlock work?

When you seal a social app, opening it shows a seal instead of the app. Answer a short quiz on the words you have been learning; get them right and the seal lifts for a set window of time. When that window closes, the seal returns. This uses Apple's Screen Time / Family Controls framework, so which apps you seal and your usage stay on your device under Apple's privacy protections. Grant the Screen Time permission when the app asks, then choose which apps to seal in settings.

How do I restore purchases?

If you reinstall the app or switch devices, open Settings in Lock In Chinese and tap Restore Purchases. Purchases are tied to your Apple ID through the App Store, so make sure you are signed in with the same Apple ID you used to subscribe.

How do I cancel my subscription?

Subscriptions are managed by Apple, not by us. On your iPhone open Settings → [your name] → Subscriptions, select Lock In Chinese, and tap Cancel Subscription. You keep access until the end of the current billing period.

How do I delete my data?

Local study records stay on the device. If you connect iCloud in a compatible build, learning history also exists in your private iCloud database. Disconnecting stops synchronization; it does not erase saved cloud history. Removing the app does not delete those cloud records. The current review-sync controls do not include cloud-history deletion. Contact support@lockinchinese.com for help with data removal.

If you previously supplied a waitlist email, you can ask us to delete that record. The website also processes the analytics and diagnostics described in our Privacy Policy.
