Privacy Policy · 隐私政策
Effective: 22 September 2026 / 生效：2026 年 9 月 22 日
Published by Darvin. Contact: shudal@qq.com. This policy covers the Android app com.emerald.yujian.
Story Mode and Practice work offline. Chapter progress, character selection, language and audio settings are stored on your device. The game does not require an account, show ads, offer purchases, access your contacts, microphone, camera or location, or use an advertising ID.
Analytics is off by default. If you enable it in Privacy & Data, the app sends a randomly generated installation ID, session and event IDs, visits, match starts/ends, game mode and play duration to our server over HTTPS. This helps us count active installations and improve the game. These identifiers are not hardware fingerprints. We do not sell this data or share it for advertising.
You can turn analytics off at any time in Privacy & Data. This stops future analytics. To request deletion of analytics already sent, email shudal@qq.com with the analytics identifier shown in that screen. We respond to deletion requests within 30 days. Records are retained until deletion is requested or the service closes. Clearing app storage or uninstalling removes local progress and identifiers, but does not itself delete previously submitted analytics.
Online mode sends a temporary room code, chosen character, player inputs and match state through our encrypted relay so the other player can join and play. No chat, voice or user-created content is available. Room and match state are kept in server memory and removed when the room closes. Your IP address is needed to establish the connection; game relay access logging is disabled and we do not put IP addresses into gameplay analytics.
Google Play may process installation, purchase-free distribution and platform security information under its own privacy policy. External links open in your browser. This game is intended for ages 13 and older and does not knowingly collect personal information from children under 13. Contact us if you believe such information was submitted.
We will update the effective date when this policy changes. Material changes to optional collection will be explained in the app.

统计默认关闭。你在「隐私与数据」主动开启后，应用会通过 HTTPS 向我们的服务器发送随机生成的安装标识、会话与事件标识、访问、对局开始和结束、游戏模式及游玩时长，用于统计活跃安装和改进游戏。这些标识不是硬件指纹；我们不出售数据，也不将数据用于广告分享。
你可随时在「隐私与数据」关闭统计，停止后续发送。如需删除已发送的数据，请将该页面显示的统计标识发至 shudal@qq.com，我们会在 30 天内处理。记录保留至你申请删除或服务关闭。清除应用存储或卸载会删除本机存档与标识，但不会自动删除已发送的统计数据。
联机时，临时房间码、所选角色、操作输入及比赛状态通过加密中转服务传递给另一位玩家。游戏没有聊天、语音或用户创作内容。房间与比赛状态仅保存在服务器内存，房间关闭后删除。建立连接需要处理 IP 地址；游戏中转访问日志已关闭，玩法统计不保存 IP 地址。
Google Play 按其自身隐私政策处理安装、免费分发及平台安全信息。外部链接在浏览器中打开。本游戏面向 13 岁及以上玩家，不会明知而收集 13 岁以下儿童的个人信息。如你认为发生了此类情况，请联系我们。
