游戏如何处理数据
游戏在设备本地保存已通关记录、最佳成绩和语言偏好，以便你继续游玩。无需登录即可游玩；我们不建立自有玩家账号或存档服务器，也不接入广告、应用内购买或独立的广告分析 SDK。0.9.0 及更早版本仅提供本地存档；以下 Google 云存档说明适用于 1.0.0 及后续支持该功能的 Android 版本。
可选的 Google 云存档
启用云存档后，游戏使用 Google Play 游戏服务和 Saved Games，将按棋盘标识保存的关卡完成情况和最佳成绩保存到你的 Google 账号关联存储，用于在同一账号的 Android 设备间同步和恢复。游戏通过玩家标识区分账号，并在设备上保存同步状态及恢复备份；不会请求读取你的电子邮件、通讯录或其他云端硬盘文件。传输使用 HTTPS。未启用云存档时，游戏不会主动上传你的闯关进度。正在进行的棋局不保存到云端，语言偏好留在本机。
Google Play 游戏服务可能根据已有账号设置自动识别玩家。Google 的服务会处理玩家身份、SDK 使用情况和诊断数据，即使你尚未启用游戏内的进度同步；这些处理受 Google 的政策和账号设置约束。参阅 Google Play 游戏服务的数据说明和 Google 隐私权政策。云存档版本使用网络权限，不请求定位、通讯录、相机或麦克风权限。
你主动开启登录时，Google 可引导创建 Play Games 玩家资料，包含玩家昵称和头像。本游戏使用 Google 玩家标识及昵称，不建立另一套开发者账号；Google 的资料创建与账号设置由 Google 管理。
黑白棋：账号与数据删除
无需重新安装黑白棋即可操作：打开 Google Play Games 个人资料 →“你的数据”→“删除 Play Games 账号和数据”，在“删除单个游戏数据”中找到 Reversi / 黑白棋并选择删除。此操作删除本游戏关联的云端进度及成绩，不要求删除整个 Google 账号。
如果你还要删除 Play Games 玩家资料，可在同一页面选择删除整个 Play Games 资料；这会影响其他游戏的资料和数据，请先阅读 Google 的确认页面。只想停止本游戏访问时，也可在 Google 账号连接管理中移除 Reversi 的连接。客服可通过上方邮箱协助说明步骤，但无法代你操作 Google 账号。
在游戏设置中停止云同步可停止后续同步，但不会删除已有云存档。你可以在 Android 设置中清除本应用数据或卸载游戏，删除设备上的进度和本地备份；云端记录独立保留，再次启用同步时可能恢复。
要删除云端游戏数据，请在 Google Play 游戏个人资料的“你的数据”中删除 Reversi / 黑白棋的单个游戏数据，具体入口以 Google 删除游戏数据帮助为准。删除前请停止所有设备的云同步，避免保留的本地进度再次上传。如需同时清除本地记录，请在各设备清除应用数据。我们没有自有玩家账号，无法替你登录或删除 Google 账号中的数据。
Smart Hippo 不在自有服务器保留玩家资料或云存档，也不另设云存档保留期。Google 负责其服务数据的处理和保留；Play 历史记录与游戏资料相互独立，可在 Google Play 活动管理中单独管理。Google 的处理期限见其隐私政策；本机进度和客服邮件不会随云端删除自动清除，处理方法见本页。

Reversi Privacy Policy
Game data
The game stores completed campaign records, best scores, and language preferences on your device. You can play without signing in. We do not operate player accounts or a save server, and do not include ads, in-app purchases, or a separate advertising analytics SDK. Version 0.9.0 and earlier provide local saves only. The Google cloud save information below applies to Android version 1.0.0 and later versions that support this feature.
Optional Google cloud saves
When you enable cloud saves, the game uses Google Play Games Services and Saved Games to store completed level records and best scores identified by board UID in storage associated with your Google account. This enables sync and recovery across Android devices using the same account. The game uses a player identifier to distinguish accounts and keeps sync state and recovery backups on your device. It does not request your email, contacts, or other Drive files. Data is transmitted using HTTPS. The game does not upload campaign progress until you enable cloud saves. In-progress games are not saved to the cloud; language preferences remain on each device.
Google Play Games Services may automatically recognize a player according to existing account settings. Google's service processes gamer identity, SDK usage, and diagnostic data, including when progress sync has not been enabled. This processing is governed by Google's policies and account settings. See Google Play Games Services data disclosures and Google's Privacy Policy. Cloud-enabled versions use internet permission, but do not request location, contacts, camera, or microphone permissions.
When you choose to sign in, Google may guide you through creating a Play Games profile, including a gamer name and avatar. Reversi uses your Google player ID and display name; it does not create a separate developer account. Google manages its profile creation and account settings.
Reversi: delete your account and data
You do not need to reinstall Reversi. Open your Play Games profile, choose Your Data, then Delete Play Games Account & Data. Under individual game data, select Reversi and delete it. This removes this game's cloud progress and scores without deleting your Google account.
The same page also offers deletion of the entire Play Games profile, which affects other games. Read Google's confirmation before proceeding. To revoke Reversi's access, use Google account connections. Contact our support email for guidance; we cannot operate your Google account.
Stopping cloud sync in game settings stops future sync but does not delete an existing cloud save. Clearing the app's data in Android settings or uninstalling it removes local progress and backups. Cloud records remain separate and may be restored when you enable sync again.
To delete cloud data, use the individual-game deletion control for Reversi in the Your Data section of your Google Play Games profile. Follow Google's game data deletion instructions for current controls. Stop sync on all devices first to prevent retained local progress from being uploaded again. To also remove local records, clear the app's data on each device. We do not operate player accounts and cannot sign into or delete data from your Google account for you.
Smart Hippo retains no player profiles or cloud saves on its servers and imposes no additional cloud-save retention period. Google controls retention of its service data. Play History is separate and can be managed through Google Play activity controls. See Google's privacy policy for its retention practices. Local progress and support correspondence are handled separately as described on this page.
Support email
If you choose to email us, we use your email address and message to respond and resolve your request. We retain correspondence only as needed for that purpose. Please avoid sending unnecessary personal information. Contact the address above to ask about or request deletion of support messages.
Google Play
When you install or update the free app through Google Play, Google may process store, device, and diagnostic data under its own policies. The game does not control that processing. See Google's Privacy Policy.
Browser links
The privacy button in settings opens your device browser. The website host may process network information needed to serve this page. This is separate from data handled inside the game. The game does not add player identifiers or progress to the link.
Changes
If a later version changes how data is handled, we will update this page, its effective date, and applicable store disclosures.
