Privacy Policy for Badugi Study (바둑이 족보 · 교환 확률)
Privacy Policy for 바둑이 족보 · 교환 확률 (Badugi Study)
Effective date: October 7, 2026
Brainer provides 바둑이 족보 · 교환 확률, package com.brainer.badugistudy, as an advertising-supported, independent card-learning application. This policy explains how the app handles information. Privacy contact: auction@mekorean.com. Developer website: https://mekorean.com.
Offline learning and local information
Card selections, hand evaluations, one-exchange calculations, quiz answers, wrong-answer review, and learning records are processed on your device. The developer does not receive these card selections or learning records and does not operate a server for them. Records and preferences remain in the app's local storage until you clear app data or uninstall the app. Android cloud backup of this app's local records is disabled. There are no user accounts, subscriptions, in-app purchases, deposits, prizes, or real-money betting services.
Advertising and Google services
The app uses Google Mobile Ads (AdMob) for banner and interstitial advertising and Google's User Messaging Platform (UMP) for applicable privacy notices and choices. When advertising is requested, Google and its advertising services may collect and share the device's IP address (which may indicate approximate location), device and account identifiers such as the advertising ID and app-set ID, app and advertising interactions, and diagnostic or performance information. These are used for advertising, measurement and analytics, and fraud prevention or security. The app does not request precise location, contacts, camera, microphone, or access to your personal files.
Advertising SDK processing can occur even when the developer does not directly receive the information. The app does not use a separate developer analytics or crash-reporting service. Google processes information according to its own policies. See Google Privacy Policy, Google advertising privacy information, and Google Mobile Ads data disclosure.
The app may offer Google's official in-app review flow after a completed learning milestone. Leaving a rating or review is optional and does not affect access to learning features. Ratings and review text that you submit are handled by Google Play, may become public on the store, and can be deleted through your Google Play or Google Account controls. The app does not receive your selected star rating or review text.
Privacy choices
Where required, the app requests an updated consent status and presents the applicable consent form before requesting ads. The app includes an advertising privacy-options entry when UMP requires it. Depending on your region and choices, ads may be personalized, non-personalized, limited, or unavailable. You can reset or delete the Android advertising ID in your device's settings. The core learning features remain available if an ad or consent request fails or the device is offline.
Security, retention, and deletion
Advertising SDK information is encrypted in transit using TLS. Local learning information is stored in the app's private device storage. No method of storage or transmission is completely secure. The developer retains no server copy of local learning information. Clear app data or uninstall the app to remove local records. Google determines retention and deletion of information it processes under its policies and your privacy controls. Contact auction@mekorean.com for privacy questions or requests; the developer cannot retrieve or identify your device-only learning records.
Audience and international processing
This app is intended for adults aged 18 and over and is not directed to children. It is an offline educational tool and does not provide gambling participation or a betting service. Google may process advertising information in countries other than your own, subject to its applicable safeguards and policies.
Changes and contact
This policy may be updated when app features or data practices change. The effective date above identifies the current policy. Contact Brainer at auction@mekorean.com or https://mekorean.com.
