Effective date: August 21, 2026
Dragon River: The Jade Mandate ("Dragon River") is an offline Chinese chess game. No account is required. Matches, move history, and game settings stay in local app storage unless you delete the app.
The free version uses Google AdMob and Google's User Messaging Platform (UMP). Ads are never shown automatically during a match: the banner appears only on the Home and completed-match Result screens, and the completed-match interstitial only after a match has finished. There are no ads during a purchase, restore, or privacy flow. Two optional rewarded videos exist, both entirely your choice: one exchanges a video for an extra 军师献策 (a suggested move) once the match's free counsel is used, and one reveals the 军师复盘 (the engine's review of the match you just finished — the number of mistakes is always shown for free, only the moves themselves are the reward). It is never started without an explicit tap, it is never required to keep playing, and players who bought permanent ad removal receive the counsel without any ad. This release requests non-personalized ads, disables the Google Mobile Ads publisher first-party ID for this app, and does not request App Tracking Transparency permission or use the IDFA for cross-app tracking.
Google's advertising services may automatically process data such as IP address (which may indicate coarse location), device or other identifiers, ad data, product interactions, diagnostics, and performance data to deliver, measure, secure, and prevent fraud in advertising. Dragon River does not receive a user profile or sell this data. Google's handling is governed by Google's Privacy & Terms.
Where required, UMP asks for consent before the Google Mobile Ads SDK is initialized. You can reopen Settings → Privacy Choices to review available advertising privacy controls.
Dragon River offers one non-consumable in-app purchase, Permanent Ad Removal, through Apple StoreKit. Apple processes payment and Apple Account transaction data. The app reads only the verified StoreKit entitlement needed to remove ads and restore the purchase. Once that entitlement is verified, Dragon River suppresses further ad requests.
Dragon River is not directed specifically to children and does not knowingly collect personal data through a developer-operated service. Advertising requests are configured as non-personalized; applicable consent and age laws still apply through Google's consent platform.
Material changes will be published on this page with a revised effective date. For privacy questions, use the channel on the support page.

《龙河玉玺》是一款离线中国象棋游戏，无需注册账号。对局、棋谱与设置保存在设备本地。
免费版使用 Google AdMob 与 User Messaging Platform（UMP）。对局中不会自动弹出任何广告：横幅广告只出现在主页和完整对局结束后的结果页，插屏广告只在一局结束之后出现；购买、恢复购买和隐私流程中不展示广告。另有两个完全可选的激励视频：本局免费的「军师献策」用完后，可以观看一段视频换取一次额外献策；对局结束后可以观看一段视频查看「军师复盘」（失着的数量始终免费显示，只有具体是哪几手才是奖励内容）。它必须由你主动点击才会开始，不看也不影响继续对局；已购买永久去广告的用户直接获得献策，不会看到任何广告。本版本仅请求非个性化广告，并为本应用停用 Google Mobile Ads 发布商第一方标识；不申请 App 跟踪透明度权限，也不使用 IDFA 进行跨 App 跟踪。
Google 的广告服务可能自动处理 IP 地址（可能推断大致位置）、设备或其他标识符、广告数据、产品交互、诊断和性能数据，用于投放、衡量、保护广告安全及防止欺诈。开发者不会获得用户画像，也不会出售这些数据。相关处理受 Google 隐私权政策约束。在适用地区，UMP 会先完成同意流程，再启动广告 SDK。你可以通过“设置 → 广告隐私选项”重新查看可用选项。
应用通过 Apple StoreKit 提供一次性非消耗型内购“永久去除广告”。付款与 Apple 账号交易信息由 Apple 处理；应用只读取经过验证的 StoreKit 权益，用于去除广告和恢复购买。权益确认后，应用会停止后续广告请求。
应用不使用开发者自建账号、分析服务、遥测或服务器，也不访问通讯录、照片、相机、麦克风、精确位置或健康数据。用户主动打开的隐私政策、条款和支持页面托管于 bubucn.com，托管方可能按其自身日志策略处理访问请求，本应用不会收到这些浏览数据。
