FAQ

随机号码真的公平吗？

本工具使用浏览器的 crypto.getRandomValues() 方法生成随机数，该方法是密码学安全的随机数生成器，比普通的 Math.random() 更公正、不可预测。每个号码的生成概率完全均等，没有任何偏向。

可以生成彩票号码吗？

可以。本工具支持设置数字范围和数量，你可以生成特定彩票游戏的号码组合。例如，双色球可以选择1-33范围内选6个号码加1-16范围内选1个号码。生成的号码仅供娱乐参考，不保证中奖。

生成的数字会重复吗？

默认设置下，生成的数字不会重复。如果你需要允许重复（如骰子点数），可以取消勾选"不重复"选项。建议彩票号码选择时启用不重复，以符合实际彩票规则。

数据会被保存或分析吗？

不会。所有随机数生成完全在浏览器本地完成，不会将任何数据发送到服务器。你的号码历史在刷新页面后会消失，不会被保存或分析。
