This app processes only the minimum information necessary to provide the service. Ads are served by Google AdMob; in-app purchase restoration is handled by RevenueCat.

1. Information Collected

  • We do not directly collect: account registration, email addresses, phone numbers, or other directly identifying information.
  • Stored locally on your device only: study progress (level and word index), saved word list, and a cached flag for the Remove Ads purchase. This data is never transmitted to external servers.
  • Third-party SDK automatic collection
    • Google AdMob (ads): advertising ID (AAID/IDFA), approximate location (IP-based), device info (model/OS), ad impressions and clicks.
    • RevenueCat (in-app purchases): anonymous user ID, store receipts (linked to your Apple ID or Google account), and purchase history. Identity verification is performed through your store account.

2. Purpose of Use

  • Providing Korean vocabulary learning features (saving progress, managing word lists)
  • Delivering and measuring ads
  • Processing in-app purchases and restoring purchase history
  • Service stability and quality management

3. Third-Party Sharing and International Transfer

  • Google LLC (AdMob): for ad delivery and measurement. Data may be processed on servers outside your country, including the United States.
  • RevenueCat Inc.: for in-app purchase processing and restoration. Data may be processed on servers outside your country, including the United States.

    We do not sell your data and do not share it beyond what is described in this policy.

4. Retention and Deletion

  • We do not maintain our own servers storing personal data.
  • Ad-related data follows AdMob's retention policy; purchase data follows RevenueCat's policy.
  • Local on-device data is deleted when the app is uninstalled.

5. Your Rights

  • You may request access, correction, deletion, or restriction of your data.
  • Contact: contact@oandh.org

6. Your Choices (Opting Out of Personalized Ads)

  • Android: Settings → Google → Ads → Opt out of Ads Personalization (or reset Advertising ID)
  • iOS: Settings → Privacy & Security → Tracking → disable per-app tracking (ATT)
  • Purchasing Remove Ads permanently disables all ads in the app.

7. Children's Privacy

This app is not directed at children. We do not knowingly collect information from children. If we learn such data has been collected, we will delete it promptly.
