Hangling

Privacy Policy

Last Updated: July 7, 2026

Hangling stores all vocabulary, progress, and streak data directly on your device. There is no account, no sign-up, and no backend server that holds your study data.

1. Overview

Hangling ("the App") is a mobile app for learning everyday Korean vocabulary and phrases. This Privacy Policy explains what information is collected and how it is used.

2. On-Device Processing

3. Information We Collect

3.1 Advertising Data

Hangling uses Google AdMob to show banner, interstitial, and rewarded ads. AdMob may collect device identifiers (IDFA/GAID) and approximate location for ad delivery. On iOS, we request App Tracking Transparency (ATT) permission before using the IDFA for personalized ads, and a consent form (UMP) is shown to users in the EEA/UK per GDPR.

3.2 Analytics & Crash Reports

We use Firebase Analytics and Firebase Crashlytics to understand feature usage and diagnose crashes. These do not include your name, email, or study content — only anonymous usage events and device/crash diagnostics.

3.3 No Purchases

Hangling does not process any payments. Premium characters are unlocked with in-app points earned by watching optional rewarded ads — no payment information is collected or transmitted.

4. Third-Party Services

5. Children's Privacy

Hangling does not knowingly collect personal information from children. Ads are configured to respect applicable content and age-rating settings.
