你目前以游客方式使用。不会自动上传本地数据。You are currently using guest mode. Local data is not uploaded automatically.
已登录：Signed in:
统一账号Shared account
先玩，再决定是否登录。Play first. Sign in when it helps.
游客可以直接浏览、试玩和保留本地存档。Google 登录只为云存档、跨设备同步、积分、购买及账号管理提供稳定身份。Guests can browse, play, and keep local saves. Google sign-in provides a stable identity only for cloud saves, cross-device sync, points, purchases, and account management.
登录不会做什么What sign-in does not do
登录本身不会接受全部法律条款，不会自动导入匿名存档，也不会把 Google Token 放进 localStorage。启用云端数据前会分别确认当前隐私和条款版本，并由你确认是否导入本地数据。Sign-in itself does not accept every legal term, automatically import anonymous saves, or put Google tokens in localStorage. Before cloud data is enabled, the current Privacy and Terms versions are acknowledged separately and you choose whether to import local data.
账号中心能力Account-center controls
账号中心支持查看会话和设备、撤销单个会话、退出全部设备、导出数据，以及删除账号和云端数据。删除账号不会删除 Google 账号或设备上的本地存档。The account center supports viewing sessions and devices, revoking one session, signing out all devices, exporting data, and deleting the account and cloud data. Account deletion does not delete the Google account or device-local saves.
地区限制Region restriction
统一账号和云数据服务仅面向中国大陆以外地区。服务端在注册、会话和每个用户数据 API 强制执行；地区无法确认时失败关闭。Shared account and cloud-data services are offered only outside mainland China. The server enforces this for registration, sessions, and every user-data API and fails closed when country cannot be confirmed.
