Thank you for using Hanitoo Korean. This policy explains what data we collect, how we use it, and your rights.
1. Data we collect
- Account data: when you choose to sign in with Google or Apple, we receive your email and display name via Firebase Authentication to identify your account and sync data. Sign-in is optional; most features work without it.
- Learning data: words you save, study progress, wrong answers, and settings. When signed in, these sync to Firebase (Cloud Firestore). Otherwise they stay only on your device.
- Purchase data: subscriptions are handled by the Apple App Store. We never see your payment details.
- Ads & device data: if you are not subscribed, Google AdMob ads may be shown. AdMob may use an advertising identifier to serve and measure ads.
2. How we use data
To provide and sync learning features, process subscriptions, show ads, improve the service, and maintain security. We do not sell your personal data.
3. Third-party services
Firebase (Google), Google AdMob, Apple/Google in-app purchases, the National Institute of Korean Language Krdict open dictionary API, and Anthropic Claude (to generate learning content). Each has its own privacy policy.
4. Retention & deletion
You can permanently delete your account and synced data at any time via Settings → Account → Delete account. This cannot be undone.
5. Children
This app is not directed to children under 13.
6. Changes
We will post any updates to this policy in the app.
