What we collect / 我们收集什么
Guest play does not require an account. We count game starts without collecting IP addresses, device fingerprints, or browser fingerprints. If you sign in with Google, we store Google's stable account identifier, your Google display name, your chosen public callsign, login timestamps, game sessions, and scores. We do not store your Google email address.
游客游玩无需账户。我们只统计游戏启动次数，不收集 IP、设备指纹或浏览器指纹。使用 Google 登录时，我们保存 Google 稳定账户标识、Google 显示名、自选公开昵称、登录时间、游玩记录和成绩；不保存 Google 邮箱。
How data is used / 数据用途
Data is used only for authentication, public leaderboards, abuse prevention, and private owner analytics. Raw game-session detail is retained for up to 90 days; daily aggregate counts may be retained permanently.
数据仅用于身份验证、公开排行榜、防滥用和主人后台统计。原始游玩明细最多保留 90 天；每日汇总数据可永久保留。
Account deletion / 删除账户
Signed-in players can request account deletion from the account controls. This removes their profile and scores and disconnects identity from prior session counts.
登录玩家可从账户控制中删除账户。删除后会移除个人资料与成绩，并断开身份和历史游玩统计的关联。
