1. Data we process and why

• Accounts: Firebase UID and, when Google is linked, provider identifiers, email, and basic profile information may be processed for sign-in, account separation, save linking, and purchase protection. The operator does not collect your Google password.
• Game and cloud saves: UID, nickname, epithet, profile choices, progression, currencies, equipment, relics, entitlements, attendance, rewards, mail, and save times are processed to save, restore, synchronize, support, and operate the Game.
• Rankings: nickname, epithet, realm, stage, and similar ranking data may be visible to other players. Do not use personal contact information as your name.
• Purchases: product ID, purchase token or receipt, order status, account link, and fulfillment records are processed to verify, grant, restore, and support purchases. Google Play handles payment card details.
• Analytics and diagnostics: Firebase Analytics and Crashlytics may process app, device, OS, installation identifiers, gameplay events, error logs, and crash information for product improvement, balancing, and troubleshooting. The Game UID is linked to these records.
• Ads and access: AdMob may process IP address, approximate location derived from IP, ad and app interactions, diagnostics, advertising ID, and app set ID to deliver and measure ads and prevent abuse. Authentication and cloud services also process connection information for security and delivery.
• Support: email address, message content, UID, order number, and attachments you provide are used to answer requests and handle account recovery or deletion.

Some data is provided by you or by an account and payment provider. Other data is generated automatically while you use the Game and its SDKs.

The Game is intended for users aged 14 and older. If we learn that data belongs to a child under 14, we will review and delete it. A parent or guardian may contact us using the details below.

2. Service providers and processing locations

• Google LLC / Firebase and Google Cloud: authentication, cloud saves, server features, diagnostics, and hosting. Firestore and server functions are configured in Seoul, Korea (asia-northeast3). Firebase Authentication and global services may process data in the United States and other countries where Google or its processors operate.
• Google LLC / Google Analytics, AdMob, and Google Play: analytics, advertising, measurement, payments, and purchase verification through Google's global infrastructure.
• NAVER / NAVER Mail: receipt, storage, and response for support email and attachments sent by the user.

Stopping required processing may limit authentication, saving, rewarded ads, or other related features. Contact us to ask about overseas processing or available deletion and restriction options.

3. Retention and deletion

• Account and game data is kept while the account remains active and is deleted after a verified deletion request, except where law requires retention.
• Ordinary support material is deleted when its purpose is complete. Transaction and dispute records may be retained for periods required by Korean consumer law, including five years for contract, payment, and supply records; three years for consumer disputes; and six months for advertising records.
• Analytics, diagnostics, access logs, and backups follow provider retention settings and technical deletion processes and may not disappear immediately when the account is deleted.

4. Account deletion and your rights

You may request account and data deletion, access, correction, or restriction even without the Game installed. Email lds0910@naver.com with the subject “Murim Master account deletion request” and include, where known, the UID, nickname, and linked email. We may request reasonable proof to prevent deletion of another person's account, but will never request your password or verification code.

Deletion covers the authentication account, cloud progress, currencies, entitlements, ranking data, rewards, and mail linked to the account. Records required by law are retained separately. App deletion or clearing device data does not delete the cloud account, and account deletion is separate from deleting a Google account or canceling a Google Play order.

5. Advertising choices

Where required, Google presents a consent message for advertising. If privacy options are available, they can be changed from the Game settings. Android advertising settings may also allow you to reset or delete the advertising ID.

6. Security

Cloud communication uses HTTPS or equivalent transport protection. Game storage uses account-based access controls, while operator tools use authenticated roles and audit important actions. These measures reduce risk but cannot eliminate every security risk.
