游戏如何处理数据
游戏在设备本地保存闯关进度、每日谜题进度、音量和语言偏好，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。1.4.3 及更早版本仅提供本地存档；以下 Google 云存档说明适用于 1.5.0 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，将关卡完成情况、棋盘及每日谜题进度保存到你的 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谜题进度。
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。
删除数字接龙数据
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 Number Chain / 数字接龙的单个游戏数据，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。
也可通过浏览器打开 Google Play 游戏个人资料，在“你的数据”中选择“删除 Play 游戏账号和数据”，然后只删除 Number Chain / 数字接龙的数据，无需删除整个 Google 账号。云端删除涉及 Google 保存的本游戏数据；设备上的进度和备份、客服邮件不会一并删除。Smart Hippo 不在自有服务器保留云存档副本；Google 服务记录的保留与删除时间以其政策为准。

Game data
The game stores campaign progress, daily puzzle progress, sound settings, 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 1.4.3 and earlier provide local saves only. The Google cloud save information below applies to Android version 1.5.0 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 levels, boards, and daily puzzle progress 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 puzzle progress until you enable cloud saves.
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.
Delete Number Chain data
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 Number Chain 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.
You can also open your Google Play Games profile in a browser, find Your Data, choose Delete Play Games account and data, then delete only Number Chain's game data. You do not need to delete your entire Google account. This removes this game's data held by Google; it does not remove progress or backups on your devices, or support correspondence. Smart Hippo retains no cloud-save copy on its own servers. Retention and deletion timing for Google's service records follow Google's policies.
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 buy, install, or update the 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.
