Privacy Policy · Jigu Korean · HarmonyOS

In short: learning in the HarmonyOS version of Jigu Korean needs no account and works offline. Only membership purchases go online, through Huawei In-App Purchases. There is no advertising or analytics SDK, and your learning data stays on your device.

1. Scope

This policy covers the HarmonyOS version of Jigu Korean (叽咕韩语, package tech.gentleflow.language.ko), operated by Lu Liang (developer brand: Gentleflow).

2. Information we process

The app processes the following on your device only. None of it is uploaded to our servers, and we do not run such servers:

Learning data: the starting level, goals and daily time you choose during setup, lesson progress, review schedule, mistakes and streak;
Preferences: speech speed, romanization display, haptic feedback, and whether and when the daily reminder fires;
Home screen service cards: the day's content shown on a card, generated from the learning data on your device.

Lesson audio, illustrations and stroke data are installed with the app and played and displayed locally. The app does not record audio and does not ask for microphone, camera, location or contacts permissions.

3. System permissions

Network access: after you accept this policy, used to query prices, make and restore purchases and refresh membership status through Huawei In-App Purchases. Your learning records are not uploaded.
Notifications and background agent reminders: requested only when you turn on the daily reminder, so the system can show a local reminder at the time you set. You can turn it off in Settings at any time.
Vibration: haptic feedback for answers and buttons; can be turned off in Settings.
Background running (audio playback): used only when you tap the pronunciation button on a home screen service card, for as long as that clip plays.

4. Membership purchases

Membership is bought through Huawei In-App Purchases; Huawei handles payment, charging, subscription management and refunds. We never receive your Huawei ID password, bank card or other payment details. The app only gets product prices, purchase receipts and subscription status from Huawei, to unlock or restore membership on your device. Signed receipts and the time they were last checked are stored on the device to verify membership; if the device cannot connect, a verified membership stays active offline for up to three days and never past the subscription's expiry. Huawei's handling of this information is governed by Huawei's privacy statement.

5. Feedback

When you email us through Feedback, we receive the content and address you choose to send, along with the app and system versions included in the email. We use them only to reply and to investigate the problem.

6. Retention and deletion

Learning data stays on your device for as long as you use the app. You can delete it in Settings › Data › Clear learning data (设置 › 数据 › 清空学习数据), or uninstall the app to remove all local data. Feedback emails are deleted within a reasonable time after the issue is resolved.

Apart from Huawei In-App Purchases as described above, we do not share, transfer or publicly disclose your personal information, except where the law requires it.

8. Your rights

You can view and change your learning preferences, turn off haptic feedback and the daily reminder, and clear your learning data at any time. You can also withdraw your consent to this policy in Settings; the app then closes and asks again the next time it opens, and your local learning data is not deleted. To access, correct or delete information we handle, such as feedback emails, contact us at the address below; we reply within 15 working days.

9. Minors

We do not knowingly collect personal information from minors. Children under 14 should use the app with a parent or guardian, and minors need a guardian's consent to buy a membership.

10. Changes to this policy

When this policy changes we update the date on this page, and for material changes to what we process, why or how, we will tell you clearly in the app.
