Overview

Korean ("we", "our", or "us") is a Korean language learning application. We are committed to protecting your personal information and your right to privacy. This Privacy Policy describes how we collect, use, and safeguard information when you use our mobile application and related services.

By downloading and using Korean, you agree to the practices described in this Privacy Policy. If you do not agree with our policies, please do not use our application.

Information We Collect

We collect information in two ways: information you provide directly, and information collected automatically when you use the app.

2.1 Information Collected Automatically

• Device Information: Device model, operating system version, unique device identifiers (IDFV on iOS, Android ID on Android), screen resolution, and system language.
• Usage Data: Features you use, lessons you access, session duration, tap/interaction patterns, error logs, and crash reports.
• Network Information: IP address, network type (Wi-Fi / cellular), and approximate geographic region (country/province level).
• App Performance Data: Load times, feature latency, and technical diagnostics to identify and fix bugs.
• Advertising Data: If you consent to personalized advertising, Google AdMob may collect your device's advertising identifier (IDFA on iOS, GAID on Android), IP address, and interaction data with ads (impressions, clicks). See Section 05 for details.

2.2 Information We Do NOT Collect

• We do not collect your precise GPS location.
• We do not access your contacts, camera, microphone, or photos unless you explicitly grant permission for a specific feature.

• We do not collect biometric data.

03

How We Use Your Information

• App Functionality: To operate Korean, sync your progress, and deliver personalized Korean lessons.
• Personalization: To adapt learning content and recommendations to your level, goals, and study history.
• Analytics & Improvement: To understand how users interact with our features, identify usability issues, and prioritize improvements.
• Advertising: To display ads through Google AdMob that help support the free version of the app. Ad personalization depends on your consent where required by law.
• Technical Support: To diagnose and fix crashes, errors, and performance issues.

• Legal Compliance: To comply with applicable laws, regulations, and legal processes.
• Safety & Integrity: To detect and prevent fraud, abuse, or violations of our Terms of Service.

04

Analytics — Firebase

Korean uses Google Analytics for Firebase and Firebase Crashlytics to collect and analyze anonymous usage statistics. This helps us understand user behavior, measure feature adoption, and improve the app experience.

Data Collected by Firebase

• Device model, OS version, and language settings
• App version, session duration, and timestamps
• Page/screen views, feature interactions, and custom event counts
• Crash logs and error reports
• General geographic region (country/city) based on masked IP addresses
• Device and app identifiers (such as Firebase Installation IDs, Android Advertising ID, or iOS IDFA/IDFV — depending on platform and user consent)

Firebase does not collect sensitive personal information such as your name, email, or precise location. Data is aggregated and used solely for statistical analysis and app stability improvements.

Firebase's Privacy Practices

Firebase processes data in accordance with Google's privacy policies. You can review Google's privacy policy at: https://policies.google.com/privacy and learn more about Firebase's privacy and security at: https://firebase.google.com/support/privacy.

05

Advertising

Korean uses Google AdMob, a third-party advertising service provided by Google LLC, to display ads within the app. Advertising revenue helps us keep the core features of the app free for all users.

Data Collected by AdMob

• Advertising Identifiers: IDFA (Identifier for Advertisers) on iOS, or Google Advertising ID (GAID) on Android — used to serve and measure ads.
• Device & App Information: Device model, operating system version, app version, and language settings.
• IP Address: Used to determine approximate geographic location for regional ad targeting and is not used to personally identify you.
• Ad Interaction Data: Such as ad impressions, clicks, and interactions within the app.
• Tracking Technologies: AdMob may use cookies or similar technologies where applicable to support ad delivery, personalization, and fraud prevention.

App Tracking Transparency (iOS)

On iOS 14.5 and later, we display Apple's App Tracking Transparency (ATT) prompt before accessing your IDFA. If you allow tracking, AdMob may use your IDFA to serve personalized ads tailored to your interests. If you deny tracking, AdMob will serve non-personalized ads based on contextual information only. You can change your choice at any time in Settings → Privacy & Security → Tracking.

Personalized vs. Non-Personalized Ads

In regions where consent is required (such as the European Economic Area and the UK), we will present a consent dialog before enabling personalized advertising. You may opt out of personalized ads at any time by adjusting your device settings:

• iOS: Settings → Privacy & Security → Apple Advertising → turn off "Personalized Ads"
• Android: Settings → Google → Ads → "Delete advertising ID" or "Opt out of Ads Personalization"

Opting out of personalized ads does not remove ads from the app; it means you will see ads that are less relevant to your interests.

AdMob's Privacy Practices

AdMob processes data in accordance with Google’s privacy policies. We do not sell your personal data. For more information, please review:

Children's Privacy

If you are a parent or guardian and believe your child under 13 has provided us with personal information, please contact us immediately. We will take steps to delete such information promptly.
