Privacy Policy
This Privacy Policy explains how the Hangeul Blocks app ("the app", "we", "us") handles information. We built Hangeul Blocks to be private by design: we do not collect, sell, or rent your personal information. The app has no user accounts and never asks for your name, email, or phone number to function.
1. Information we do not collect
The app has no login or registration. We do not collect your real name, email address, contacts, photos, precise location, or any directly identifying information on our own servers — because we do not operate servers that store your personal data.
2. Information processed on your device and in your iCloud
Learning progress. Your scores, streaks, review schedule, and game settings are stored locally on your device. If you are signed in to iCloud, this data may sync across your own Apple devices using Apple's iCloud (CloudKit). It is stored in your iCloud account; we cannot read it. This data is governed by Apple's Privacy Policy.
3. Purchases
Hangeul Blocks offers a single optional one-time in-app purchase ("Premium"). All payments are processed by Apple through the App Store using StoreKit. We never see or store your payment-card details. Apple shares with us only an anonymous receipt confirming whether the purchase is active, so the app can unlock Premium features.
4. Advertising & tracking
Hangeul Blocks shows no advertising and includes no third-party advertising, analytics, or behavioral tracking. The app does not present an App Tracking Transparency (ATT) prompt and never accesses your advertising identifier — there is nothing to opt in or out of.
5. Children's privacy
Hangeul Blocks is suitable for all ages. The app has no ads, no tracking, and no user accounts, and it does not knowingly collect personal information from anyone, including children. If you believe a child has provided us personal information, contact us and we will address it.
6. Analytics
The app does not include third-party advertising, analytics, or behavioral tracking SDKs. Apple may provide us with aggregate, anonymized App Store and crash statistics if you have opted in to share analytics with developers in your iOS settings; this data is not linked to your identity.
7. Data summary
| Data | Purpose | Who handles it |
|---|---|---|
| Learning progress & settings | Save your progress, sync across your devices | On device + your iCloud (Apple) |
| Purchase receipt | Unlock Premium | Apple (StoreKit) |
8. Your choices
- Delete all local progress by removing the app; manage iCloud data in iOS Settings → [your name] → iCloud → Manage Account Storage.
9. Data retention & security
Because progress is stored on your device and in your own iCloud, you remain in control of it. We apply reasonable measures appropriate to an app that holds no central database of users.
10. Changes to this policy
We may update this policy as the app evolves. Material changes will be reflected here with a new "Last updated" date.
