Privacy Policy

Battle Rummy ("the app") is provided by Lee Eungsuk.

Overview

Battle Rummy is a mobile board game based on rummy-style gameplay. The app supports solo practice against AI and local versus play over Bluetooth.

Battle Rummy does not operate its own gameplay backend server or standalone user database. Core gameplay is designed to work without account creation or sign-in.

Information We Collect

The app itself does not ask users to create an account, upload public content, or submit profile data to a developer-operated server.

Depending on the app version and enabled services, the following information may be processed:

• Device and app information, such as app version, device model, operating system version, language, and general diagnostics
• App activity and usage events, such as app opens, sessions, screen views, gameplay events, and feature usage
• Advertising or app instance identifiers, when supported by the device or third-party SDKs
• Approximate location inferred from IP address by advertising providers
• Bluetooth-related access needed to discover or connect to nearby devices for local multiplayer
• Basic network state or connectivity information when required by the platform or SDKs

How We Use Information

• Provide local Bluetooth multiplayer functionality
• Maintain and improve app stability and gameplay quality
• Measure usage and performance through analytics
• Show ads and measure ad performance
• Detect abuse, invalid traffic, crashes, or technical issues

No Developer-Operated Account System

Battle Rummy does not currently provide:

• developer-operated online matchmaking
• developer-hosted user accounts
• cloud save tied to a personal account
• a separate backend database for player content

Gameplay data is generally processed on-device unless third-party services described in this policy are enabled.

Firebase Analytics

Battle Rummy may use Firebase Analytics, a Google service, to understand how the app is used and to improve the product.

Firebase Analytics may process information such as:

• app launches and sessions
• device and app identifiers
• gameplay or interaction events
• technical and diagnostic data

For more information about how Google processes data, see Google Privacy Policy and Firebase privacy and security information.

Advertising and AdMob

Battle Rummy may use Google AdMob to display advertisements.

If AdMob is enabled, Google and its partners may process information such as:

• advertising identifiers
• app interaction data
• IP address
• approximate location derived from IP address
• diagnostic information
• performance and fraud-prevention signals

Advertising data may be used to deliver, measure, and improve ads, including limited personalization where permitted by law and app settings.

For more information, see Google Privacy Policy and Google AdMob Help.

Data Sharing

The app does not intentionally sell personal information.

Information may be shared only as needed with service providers and platforms that operate app features, analytics, or advertising, including Google services such as Firebase Analytics and AdMob.

Data Retention

Because the app does not currently maintain a developer-operated user account system or separate backend database, the developer does not maintain a dedicated server-side account record for ordinary gameplay.

Retention of analytics or advertising-related data is governed by the applicable third-party service providers and their policies.

Data Deletion

Because the app does not currently maintain user accounts on a developer-operated backend, there is generally no server-side account record for the developer to delete.

Users may stop using the app at any time and may remove app data by uninstalling the app or clearing local app storage on their device.

Children's Privacy

Battle Rummy is not intended to solicit personal information directly from children through a developer-operated account or upload system.

Parents or guardians should review app use where required by local law or platform policy.

Security

Reasonable efforts are made to protect the app and related services. However, no method of electronic transmission, storage, or processing can be guaranteed to be completely secure.

International Use

The app may be made available in multiple countries and languages. Third-party services used by the app may process data in different countries in accordance with their own privacy practices.

Changes to This Policy

This Privacy Policy may be updated from time to time. The latest version will be published at the active policy URL and will include a revised effective date.
