Hasegi Inc. ("we") values your privacy and complies with the Personal Information Protection Act of the Republic of Korea and relevant laws.
The Service does not require sign-up, so we do not collect personally identifiable information such as name, email, or phone number. The following data is processed automatically:
| Type | Details | Storage |
|---|---|---|
| Learning state | Bookmarks, recently viewed sentences, streak counts | Local device (SharedPreferences) |
| Advertising identifier | iOS IDFA / Android Ad ID (with user consent) | Google AdMob servers |
| Device & usage | OS, app version, device model (for ad delivery) | Google AdMob servers |
The Service uses Google AdMob to display ads. Because this is a learning app that may be used by children, the following protections are applied app-wide to every ad request:

You can additionally disable the advertising identifier through your device settings:

The Service offers a one-time, non-consumable in-app purchase ("Inception Premium"). All payments are processed entirely through Apple App Store or Google Play. We do not directly collect or retain any payment information such as card numbers or bank details. The only purchase-related data we recognize is the ownership flag, stored locally on your device.
We do not retain personally identifiable information on our servers. Learning data stored locally is deleted when the app is removed.
We do not share your information with third parties except as required by law or as described above for advertising delivery to Google AdMob.
We may entrust Google LLC (AdMob) with the processing of advertising identifiers for ad delivery purposes.
You may opt out of advertising identifier use at any time. To delete your learning data, simply uninstall the app. For additional rights, contact us below.
The Service is designed to be usable by children under 14. We do not collect identifiable personal information, so no separate guardian consent process is implemented. Additionally, the following protections are applied app-wide:
