Hangul Studio — Privacy Policy

Effective date: October 11, 2026

1. Information we collect

- No account is needed. We do not ask for your name, email address or phone number. - Your study progress, section checkmarks and notes are saved only on your device and are never sent to our servers. - Lessons you unlock by watching ads are also recorded only on your device. - Advertising data: when you watch a rewarded ad, Google AdMob may collect your device's advertising identifier (only if you allow tracking), IP address, device model, OS version and how you interact with ads. - Purchases are handled by Apple. We never receive your payment details such as card numbers.

2. How we use it

To show rewarded ads that unlock lessons, to confirm and restore your full-course purchase, and to keep your study records on your device.

3. Third-party services

The App uses the services below, and your information is handled under each provider's own policy. - Google AdMob (ad delivery): https://policies.google.com/privacy - Apple App Store (in-app purchases) - Apple text-to-speech (pronunciation playback runs on your device)

4. Sharing with third parties

We do not share personal information with third parties, except the advertising data that Google AdMob needs to show ads, or where required by law.

5. Your choices

- Tracking: you can allow or deny tracking when the App asks, and change it any time in iPhone Settings > Privacy & Security > Tracking. Ads still appear if you deny it, but they are not personalized. - You do not have to watch ads. You can unlock lessons with a one-time purchase instead.

6. Retention and deletion

Everything the App stores is kept on your device. Deleting the App erases your progress, notes and the lessons you unlocked with ads. A full-course purchase can be recovered at any time with "Restore Purchase".

7. Children

Children under 13 should use the App only with a parent's or guardian's consent.

8. Changes to this policy

We may update this policy when needed. We will tell you inside the App about any important change.
