Privacy policy
Effective October 22, 2026. This policy covers Mahjong Bloom (叠趣麻将), bundle ID com.sanfenggames.mahjongbloom. Contact: wdlgame@gmail.com.
Local data and purchases
Levels, daily challenges, tools, selected avatars and preferences are stored on your device. Core play does not require an app-managed account. There is no app-managed cloud save, chat or player content feed. Optional Game Center leaderboards share the information described below. The app does not request your address book, camera, microphone or precise-location access. Deleting the app may remove local progress.
Apple StoreKit handles payments and orders. The game reads localized product information and verified entitlements to unlock or restore Pro and respond to refunds or revocations. We do not receive card details or Apple passwords or send transactions to a developer-operated server.
Game Center and leaderboards
If you sign in to Apple Game Center, the game uses your Game Center player identifier and display name to submit and display your best campaign progress and daily challenge score. If you select a country or region in your profile, its code is sent with new best scores and may appear as a flag beside your leaderboard entry. This is a choice you make, not a location inferred from GPS or your Apple Account. Rankings, display names, Game Center photos and selected regions can be visible to other players through Game Center. Your locally selected game avatar is not uploaded.
The optional friends leaderboard uses GameKit's friends permission, separate from access to your address book. You can decline sign-in or this permission and continue core play. Progress awaiting submission is stored locally and retried when Game Center is available. We do not operate a separate leaderboard server. Apple controls Game Center account records, retention and privacy choices under its Game Center privacy information.
Advertising and consent
The app uses Google AdMob and UMP. These services may process IP-derived approximate location, app or device identifiers, ad impressions and interactions, usage events, and crash or performance diagnostics for ad delivery, measurement, analytics and security. Processing depends on region, consent, system permissions and Google configuration. See Google's privacy policy and SDK disclosure.
This launch version requests non-personalized ads and disables Google's publisher first-party advertising ID. It does not request ATT authorization or use IDFA without system authorization. Non-personalized ads still process the data described above for delivery, measurement, security and frequency control. UMP refreshes consent and presents forms when required; Settings exposes required privacy options. Core gameplay works offline. Pro removes automatic interstitial ads while voluntary rewarded ads remain available.
Support, retention and choices
If you email support, we receive your address, message and any device details you provide for responding, troubleshooting and necessary records. Do not send sensitive account or payment information. Delete the app to clear its local data. Google's services retain data under their policies. We do not sell information you email to support. Contact us for access or deletion requests; Apple and Google independently control their records.
Children, this site and updates
The service is not specifically directed to children and does not ask children to submit personal information. Contact us if a child has sent personal information to support. Policy changes carry an updated date and reflect new practices.
This site includes no advertising, analytics scripts, forms or tracking cookies set by us. Hosting infrastructure may process request IP addresses and technical logs to serve the pages.
