一笔安万民隐私政策
适用范围
本隐私政策适用于移动游戏《一笔安万民》（Hanzi: City of Strokes）及其相关服务。我们不会要求您主动创建账号，也不提供第三方账号登录。首次运行时，应用会为设备生成一个游客身份，用于保存游戏数据和提供相关功能。
我们处理的信息
根据您使用的功能、网络状态和广告展示情况，我们可能处理以下信息：
- 设备与标识符：游客设备 ID、广告标识符或其他设备标识符，以及应用版本、操作系统和设备基本信息。
- 应用活动：应用安装、打开、教程完成、达到指定关卡、激励广告完成和广告收入等事件。
- 应用信息与性能：崩溃、诊断、性能和请求结果等技术信息。
- 大致位置：广告和归因服务可能根据 IP 地址或设备网络信息推断大致位置；我们不会请求您的精确 GPS 位置。
- 游戏数据：游戏进度、设置、同步状态及与游戏存档相关的版本信息。
本地存档与云端同步
游戏存档首先保存在您的设备本地，应用在可用时也会将游客身份关联的存档和必要的同步信息发送到我们的服务器，用于跨启动恢复、备份和处理同步冲突。游戏在服务器不可用时仍可继续进行；如果未来停止服务器服务，应用仍会保留本地存档并继续支持本地游玩。
卸载应用或通过设备系统清除应用数据，可能会删除本地存档。当前应用没有用户自助删除云端数据的入口；如需咨询或提出删除请求，请通过下方邮箱联系我们。
广告与分析服务
应用使用 Google Mobile Ads SDK（AdMob）展示激励广告。AdMob 可能处理广告标识符、设备和网络信息、大致位置、广告展示与互动、诊断和性能数据，用于提供广告、衡量广告效果、防止欺诈和维护服务。
应用使用 AppsFlyer 处理安装归因、应用分析和广告收入回传。AppsFlyer 可能接收设备或广告标识符、应用活动事件、大致位置及诊断信息。我们会发送必要的广告收入事件，用于衡量广告表现和计算用户生命周期价值。
截至本政策生效日，应用尚未接通 TikTok Ads，因此不会依据 TikTok Ads 集成向 TikTok 分享上述数据。未来如接入新的广告或归因服务，我们会在更新本政策和相关商店披露后使用。
信息用途
- 提供游戏、存档、同步和客户支持功能；
- 了解应用使用情况并改进稳定性、性能和体验；
- 展示激励广告、衡量广告收入和投放效果；
- 进行归因、反欺诈、安全防护和遵守法律义务。
信息分享与传输
我们会将实现上述功能所必需的信息提供给我们的服务器、Google AdMob 和 AppsFlyer。我们的 API 使用 HTTPS 传输；广告和归因 SDK 使用其服务提供的加密网络连接。我们不会出售个人信息。
我们不会要求您创建账号，也不会将游客身份直接显示为您的姓名。我们会在实现相关目的所需的期间保留信息，或根据法律要求保留。第三方服务对信息的处理还受其各自隐私政策约束。
儿童隐私
本应用的目标受众为 13 岁及以上用户，不以儿童为目标受众。我们不会故意收集儿童的个人信息。如果您认为儿童向我们提供了个人信息，请通过下方邮箱联系我们。
政策更新与联系方式
当应用功能、第三方服务或法律要求发生变化时，我们可能更新本政策，并在本页面更新生效日期。发布者为 Fried Yuanxiao。

Privacy Policy
Scope
This Privacy Policy applies to the mobile game Hanzi: City of Strokes and its related services. We do not require you to create an account and do not provide third-party account login. On first use, the app generates a guest identifier for the device to support game data and related features.
Information We Process
Depending on the features you use, network availability, and ad delivery, we may process:
- Device and identifiers: a guest device ID, advertising or other device identifiers, app version, operating system, and basic device information.
- App activity: installation, app open, tutorial completion, reaching a specified level, rewarded-ad completion, and ad-revenue events.
- App information and performance: crash, diagnostic, performance, and request-result information.
- Approximate location: advertising and attribution services may infer approximate location from IP address or network information. We do not request precise GPS location.
- Game data: game progress, settings, sync status, and version information needed for save data.
Local Saves and Cloud Sync
Game saves are stored on your device first. When available, the app also sends the guest-associated save and necessary sync information to our server for recovery, backup, and conflict handling. The game remains playable when the server is unavailable. If we later discontinue the server, the app will retain local saves and continue to support local play.
Uninstalling the app or clearing its app data may delete local saves. The app currently has no self-service control for deleting cloud data. Contact us at the email below if you have a deletion request or question.
Advertising and Analytics Services
The app uses the Google Mobile Ads SDK (AdMob) to show rewarded ads. AdMob may process advertising identifiers, device and network information, approximate location, ad impressions and interactions, and diagnostic and performance data to deliver ads, measure ad performance, prevent fraud, and maintain its services.
The app uses AppsFlyer for install attribution, app analytics, and ad-revenue reporting. AppsFlyer may receive device or advertising identifiers, app activity events, approximate location, and diagnostic information. We send necessary ad-revenue events to measure advertising performance and user lifetime value.
As of the effective date of this policy, the app is not connected to TikTok Ads, so the app does not share the above data with TikTok through a TikTok Ads integration. If we add another advertising or attribution service, we will update this policy and the relevant store disclosures before using it.
How We Use Information
- Provide gameplay, saves, sync, and support;
- Understand usage and improve stability, performance, and the user experience;
- Show rewarded ads and measure advertising revenue and campaign performance;
- Perform attribution, fraud prevention, security, and legal compliance.
Sharing and Transfers
We provide information necessary for these purposes to our server, Google AdMob, and AppsFlyer. Our API uses HTTPS; the advertising and attribution SDKs use encrypted network connections provided by their services. We do not sell personal information.
We do not require an account and do not display the guest identifier as your name. We retain information for as long as needed for the purposes described above or as required by law. Processing by third-party services is also subject to their respective privacy policies.
Children's Privacy
The app is intended for users aged 13 and older and is not directed to children. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us at the email below.
Updates and Contact
We may update this policy when app functionality, third-party services, or legal requirements change. The effective date on this page will be updated accordingly. The publisher is Fried Yuanxiao.
