Overview
Zentjong is a Mahjong-solitaire-inspired puzzle game for Android. The app can
be played without creating an account and does not include a
Zentjong-operated backend service.
Zentjong does not use cloud save, user accounts, leaderboards, analytics, crash
reporting, or developer-operated support tooling.
Information Stored On Your Device
Zentjong stores game-related preferences and statistics locally on your device,
including:
Sound and vibration settings.
Theme choice.
Games started.
Games won.
Best move count.
This local data is stored with Android DataStore. Zentjong does not
intentionally upload this local settings or statistics data to a developer
server.
Advertising And Consent
Zentjong uses Google AdMob for advertising and Google User Messaging Platform
for consent management. Zentjong does not currently use other third-party
analytics, account, cloud-save, or crash-reporting SDKs.
Google AdMob and Google's User Messaging Platform may process data such as:
Advertising ID and other device identifiers.
Ad views, ad clicks, rewarded-ad interactions, and other ad-related app
interactions.
Approximate location or inferred region used for advertising, consent, fraud
prevention, and compliance.
Device, diagnostics, and performance information related to ad delivery.
Consent status and privacy choices.
This data may be processed by Google according to Google's own policies and the
privacy choices available to the user.
Privacy Choices
When required, Zentjong shows privacy options in the Settings screen through
Google User Messaging Platform. Availability of the Privacy Options control
depends on Google's reported requirements for the user's region and consent
state.
Users can also reset local Zentjong data through Android system settings by
clearing app data or uninstalling the app.
Children And Families
Zentjong is intended for a general audience and is not specifically directed to
children.
Sharing
Zentjong does not share local settings or game statistics with a
developer-operated server.
Google AdMob and Google User Messaging Platform may collect, process, and share
data as described by Google and controlled by applicable user choices and law.
Secure Data Handling
Zentjong stores local app preferences and statistics using Android platform
storage. Data transmitted by Google AdMob or Google User Messaging Platform is
handled by those Google SDKs according to Google's security and privacy
practices.
Data Retention
Local settings and statistics remain on the device until the user clears app
data, uninstalls the app, or the app changes its storage behavior.
AdMob and Google User Messaging Platform data retention is controlled by Google
and the user's privacy choices.
This retention statement reflects the current Zentjong release.
