Privacy Policy / 隐私政策
This policy describes what we collect to run the game and pay out rewards.
Data we collect: your nickname and language preference; gameplay data (scores, action logs, device model/app version, timezone) used to verify fair play; a device identifier used only for anti-cheat (limiting how many accounts one device can hold); a push notification token, if you allow notifications; and, only if you are awarded a physical prize, the shipping address you provide.
How it's used: ranking leaderboards, verifying submissions server-side, detecting shared/abusive devices, sending you reward and reminder notifications, and mailing physical prizes.
Retention: reward grant records are kept permanently for financial/audit purposes and are never deleted, even on request, once a reward has been issued. Shipping addresses are retained as part of that same record. Other account data can be deleted on request except where retention is required for the reasons above.
Third parties: we use Supabase for backend storage and Firebase Cloud Messaging for push notifications; if you sign in with Apple or Google, those providers process your sign-in per their own privacy policies. We do not sell your data.
Contact us to request access to or deletion of your data, subject to the retention limits above.
隐私政策
本政策说明我们为运营游戏和发放奖励而收集哪些信息。
我们收集的信息：昵称与语言偏好；游戏数据（分数、操作序列、设备型号/App 版本、时区），用于验证成绩真实性；仅用于反作弊目的的设备标识（限制同一设备关联的账号数量）；如果你开启了通知权限，会收集推送 token；以及——仅当你获得实物奖品时——你填写的收货地址。
用途：排行榜排名、服务端成绩核验、识别共用/滥用设备、向你发送获奖与提醒通知、以及邮寄实物奖品。
保留期限：发放记录出于财务/审计目的将永久保留，一旦奖励已发放，即使你提出删除请求也不会删除；收货地址作为同一记录的一部分同样保留。其他账号数据可应你的请求删除，但受上述保留要求限制的部分除外。
第三方：我们使用 Supabase 提供后端存储服务，使用 Firebase Cloud Messaging 发送推送通知；如果你使用 Apple 或 Google 登录，这些服务商会按其自身隐私政策处理你的登录信息。我们不会出售你的数据。
如需查询或删除你的数据（受上述保留期限限制），可联系我们。
