中文
本应用无需应用账号。棋局和 AI 在设备上运行。广告、购买和段位同步使用 Google 服务并需要网络。
本地数据
应用在私有存储中保存语言、音效、计时器和席位偏好，以及每款游戏的一个存档、每日免费额度、该局悔棋用量和购买权限缓存。每款游戏的存档独立保存，不会因跨天或关闭应用而删除。再次保存只覆盖同一游戏的存档。卸载应用或清除应用数据会删除本地存档。存档和额度/权限缓存不参与 Android 备份；普通偏好设置可由 Android 备份至你的 Google 账号。
广告与购买
应用集成 Google AdMob 和 User Messaging Platform，用于奖励广告、结算广告和隐私选择。Google Mobile Ads SDK 会处理 IP 地址、设备/账号标识符、应用和广告互动以及诊断信息，用于广告、分析和防欺诈。具体处理取决于 SDK 配置及隐私选择。Google 的说明见 SDK 数据披露 和 Google 隐私政策。需要时，应用会显示同意表单，并提供“广告隐私”入口。
Premium 购买及恢复通过 Google Play 处理。应用读取购买状态并在本机验证购买签名以解锁 Elite，不读取付款卡资料。重装后可通过 Google Play 恢复符合条件的购买；本地棋局存档不会因此恢复。
应用记录不含玩家标识符或购买令牌的本地功能诊断事件。本版本未配置开发者自有的分析数据上传服务。Google SDK 仍会按其服务说明处理数据。
段位与 Google Play 游戏
段位（每款游戏每档 AI 的段位和已点亮的菱形）保存在设备上，并可随普通偏好设置由 Android 备份。登录 Google Play 游戏是可选的：登录后，应用会把段位保存到你的 Google Play 游戏云存档，用于在你的设备之间同步，以及重装或换新设备后恢复。云存档只包含段位和同步所需的计数，不包含棋局存档、对局记录或购买信息。登录和云存档由 Google 通过 Play 游戏服务处理，并会使用你的 Play 游戏个人资料，适用 Google 隐私政策。应用在设备上只保存玩家标识的不可逆摘要，用来判断段位上次与哪位玩家同步，不保存也不记录玩家 ID。你可以在 Google Play 游戏中退出登录，或管理、删除该游戏的数据。
权限、受众和联系
网络权限用于广告、隐私表单、购买和段位同步。应用面向 13 岁及以上用户。

English
The app requires no app account. Games and AI run on your device. Advertising, purchases and rank sync use Google services and require network access.
Local data
Private storage holds language, audio, clock and seat preferences, one save per game, daily allowances, match Undo usage, and a purchase entitlement cache. Each game’s slot persists across days and app restarts. Saving again replaces only that game’s slot. Uninstalling the app or clearing its data deletes local saves. Saves and allowance/entitlement caches are excluded from Android backup; ordinary preferences may be backed up by Android to your Google account.
Ads and purchases
The app integrates Google AdMob and the User Messaging Platform for rewarded ads, result-screen ads and privacy choices. Google Mobile Ads processes IP addresses, device/account identifiers, app/ad interactions and diagnostics for advertising, analytics and fraud prevention, depending on SDK configuration and privacy choices. See Google’s SDK data disclosure and the Google Privacy Policy. Where required, the app presents a consent form and an “Ad privacy” control.
Google Play handles Premium purchases and restoration. The app reads purchase status and verifies purchase signatures locally to unlock Elite; it does not read payment card details. Eligible purchases can be restored through Google Play after reinstalling. This does not restore local saved games.
The app records local feature diagnostics without player identifiers or purchase tokens. This version has no developer-operated analytics upload service. Google SDKs still process data as described in their service disclosures.
Ranks and Google Play Games
Ranks (each game’s rank and lit gems at every AI level) are stored on your device and may be backed up by Android with ordinary preferences. Signing in to Google Play Games is optional. Once you sign in, the app keeps your ranks in your Google Play Games cloud save, to sync them between your devices and restore them after a reinstall or on a new device. The cloud save holds only the ranks and the counters needed to sync them, not saved games, match history or purchase information. Google handles sign-in and the cloud save through Play Games Services, using your Play Games profile, under the Google Privacy Policy. On your device the app keeps only a one-way digest of the player identifier, to tell which player the ranks were last synced with; it neither stores nor logs the player ID. You can sign out of Google Play Games, or manage and delete this game’s data there.
Permissions, audience and contact
Network access supports ads, privacy forms, purchases and rank sync. The app is intended for users aged 13 and over.
