Privacy Policy — KOREA DRIVING MASTER (한국 운전면허 마스터)

1. Independent Educational Status, Translation Transparency & Non-Affiliation Disclaimer

KOREA DRIVING MASTER is an independent educational study application developed and published by ALISOPLAY (Alisoplay).

The application is NOT an official government application and is NOT affiliated with, endorsed by, or sponsored by the Korea Road Traffic Authority (KoROAD / 한국도로교통공단), the Korea Transportation Safety Authority (TS / 한국교통안전공단), the SafeDriving official portal (safedriving.or.kr), the National Police Agency, or any government entity of the Republic of Korea.

All 1,260 questions feature verified Korean, English, and Arabic translations; draft machine-translated questions in ur, ne, si, fil, and uz are transparently labeled in-app with the badge "Draft Translation — Pending Human Legal/Linguistic Review".

2. Guest-First Local Study Data & Optional ALISOPLAY ID Cloud Synchronization

KOREA DRIVING MASTER is Guest-First: you can open and use the app immediately as a Guest without creating an account. Your study progress, practice history, bookmarks, wrong-answer review queues, and language preferences are stored locally on your Android device using SQLite (sqflite) and SharedPreferences.

Optionally, you may create or sign in to a unified ALISOPLAY ID account using Email & Password or Google Sign-In (OAuth 2.0 ID token verification). Signing in enables optional cloud synchronization of your KOREA DRIVING MASTER study progress across devices (https://alisoplay.com/api/mobile/kdm/sync) and account-linked subscription verification.

When signing in from Guest mode, you can choose whether to keep local progress only or merge compatible local progress with your account. Study progress for KOREA DRIVING MASTER is strictly isolated from other ALISOPLAY applications.

• Local & Cloud Study Records: Completed lessons, practice attempts, mock exam history, bookmarks, wrong-answer queues, and topic mastery
• Optional ALISOPLAY ID Profile: Email address, display name, hashed password (for email accounts) or verified Google OAuth subject identifier (for Google Sign-In), and active session refresh token hash
• Selected interface and study language (ko, en, ar, ur, vi, ne, si, fil, zh, uz) and theme settings

3. Google Play Billing, Purchase Tokens & Server-Side Subscription Verification

KOREA DRIVING MASTER offers a Free tier (10 designated questions per bank = 110 free questions total, plus 1 introductory lesson per learning track) and optional auto-renewing Premium subscriptions (Weekly Premium: kdm_premium_weekly, Monthly Premium: kdm_premium_monthly).

All payment transactions are processed directly by Google Play Billing. ALISOPLAY never receives, processes, or stores your credit card number, bank account details, or raw payment credentials.

To verify active entitlements and prevent unauthorized tampering, the application transmits the Google Play purchase token, product ID, and package name over encrypted HTTPS to the ALISOPLAY verification endpoint (https://alisoplay.com/api/mobile/kdm/billing/verify), which validates subscription status and expiry time with the official Google Play Developer API (subscriptionsv2) and processes Google Play Real-time Developer Notifications (RTDN).

• Purchase Token & Order ID: Used strictly to verify subscription status (FREE, PREMIUM_ACTIVE, PREMIUM_EXPIRED, PREMIUM_PENDING), renewal/expiry timestamps, and purchase acknowledgement
• Tamper-Evident Offline Receipt Cache: A cryptographically signed verification receipt is cached on your device so legitimate active subscribers retain Premium access during temporary offline periods

4. Google AdMob Advertising (Banner, Interstitial & Native Ads)

For users on the Free tier, KOREA DRIVING MASTER integrates the official Google Mobile Ads SDK (Google AdMob, App ID: ca-app-pub-5662448443036988~6012438567) to support three advertisement formats: Adaptive Banner ads, Interstitial ads at natural session transitions (with strict frequency cooldowns and never during active timed questions), and clearly labeled Native ads.

When a user holds an active verified Premium subscription (PREMIUM_ACTIVE), all Banner, Interstitial, and Native advertisements are immediately disabled and removed.

When advertisements are active on the Free tier, Google AdMob may automatically collect and process the following data over HTTPS, subject to your consent:

• Device or Other IDs: Android Advertising ID (com.google.android.gms.permission.AD_ID / GAID) for ad delivery, frequency capping, and fraud prevention
• Approximate Location: Coarse IP-based geographic region for regional ad relevance and regulatory compliance (the app never requests GPS permissions)
• App Interactions & Diagnostics: Ad impression/click events, SDK crash logs, and screen dimensions required for adaptive ad rendering

5. User Privacy Choices & Google User Messaging Platform (UMP)

KOREA DRIVING MASTER integrates Google User Messaging Platform (UMP) to manage user consent in the European Economic Area (EEA), the United Kingdom, and other applicable jurisdictions.

Before requesting advertisements, the application checks UMP consent status and respects whether ads may be requested. Users can review or update their privacy choices anytime in Settings or reset their Android Advertising ID in Android Settings > Google > Ads.

6. Android Permissions, Data Retention & Two-Tier Account / Data Deletion Rights

The application requests only android.permission.INTERNET, com.google.android.gms.permission.AD_ID, and com.android.vending.BILLING (for Google Play subscriptions). It never requests camera, microphone, contacts, or GPS permissions.

You have full control over both local and cloud data deletion, with two distinct deletion options available directly in the app (Settings > ALISOPLAY ID Account > Delete Account / Data) or on the web at https://alisoplay.com/en/account-deletion (and https://alisoplay.com/en/apps/korea-driving-master/account-deletion):

(A) Delete KOREA DRIVING MASTER Application Data Only: Permanently deletes your synchronized KOREA DRIVING MASTER cloud study progress while keeping your unified ALISOPLAY ID account active for other ALISOPLAY apps. (B) Delete Unified ALISOPLAY ID Permanently: Permanently deletes your entire ALISOPLAY ID account, sign-in credentials, active sessions, and all synchronized cloud data across all connected ALISOPLAY services. Please note that deleting your account does not automatically cancel an active Google Play subscription; manage or cancel subscriptions in Google Play Store > Subscriptions.
