TankDuo隐私政策
1. 概述
TankDuo是一款面向iPhone和iPad的原创复古坦克游戏，提供单人战役和附近双人合作。我们重视你的隐私，并将数据处理限制在实现本地游戏功能所必需的范围内。
TankDuo is an original retro tank game for iPhone and iPad with a solo campaign and nearby two-player co-op. We respect your privacy and limit data processing to what is necessary for local game features.
2. 我们收集哪些信息
TankDuo无需注册账号，不包含广告、第三方分析或用户跟踪SDK，也不会把个人资料、游戏记录、设备标识符或位置信息上传到开发者服务器。
TankDuo does not require an account, include advertising, third-party analytics, or tracking SDKs, and does not upload personal information, gameplay records, device identifiers, or location data to the developer's servers.
3. 本地存储内容
TankDuo使用Apple提供的UserDefaults在设备本地保存最高分和音效开关。这些设置不会由TankDuo发送给开发者或第三方。删除App会一并删除这些本地设置。
TankDuo uses Apple's UserDefaults to save the high score and sound preference locally on your device. These settings are not sent to the developer or third parties and are removed when the app is deleted.
4. 附近双人联机
当你主动进入附近双人模式时，TankDuo使用Apple的MultipeerConnectivity在两台附近设备之间发现并建立加密连接。系统可能根据环境使用本地网络、点对点Wi-Fi或蓝牙能力。
- 附近广播使用随机生成的
TankDuo-四位码，不会广播用户设置的设备名称。 - 连接期间，两台设备会直接交换移动、开火和战场状态数据。
- 对局数据不会上传到开发者服务器，也不会在对局结束后由TankDuo另行保存。
When you enter nearby co-op, TankDuo uses Apple's MultipeerConnectivity to discover and establish an encrypted connection between two nearby devices. The system may use the local network, peer-to-peer Wi-Fi, or Bluetooth capabilities depending on the environment.
5. 系统权限
附近双人模式需要本地网络和蓝牙相关权限，仅用于发现附近玩家和传输对局状态。拒绝这些权限不会影响单人模式。
Nearby co-op requires local network and Bluetooth-related permissions only to discover nearby players and exchange gameplay state. Denying these permissions does not affect solo play.
