我们为什么存在Why we exist

熬夜不是因为不知道熬夜不好。几乎每个晚睡的人都清楚代价，也都试过下决心。问题在于，决心是一次性的，而夜晚是每天都会来的。People do not stay up late because they are unaware it is bad for them. Almost everyone who sleeps late knows the cost and has resolved to change. The trouble is that resolve happens once, and night comes every day.

Liumi Tech 想做的，是把「今晚早点睡」这件事，从一次意志力的对抗，变成一段每天都愿意重复的体验。这需要设计、需要节制，也需要对数据保持诚实——三者缺一，产品就会退回成又一个让人内疚的记分板。What Liumi wants to build is a way to turn "go to bed earlier tonight" from a contest of willpower into an experience worth repeating every day. That takes design, restraint, and honesty about data. Without all three, the product falls back into being one more scoreboard that makes people feel guilty.

我们坚持的原则Principles we hold

• 不制造焦虑。产品不对用户的身体状况下判断，不用评分制造压力，也不把健康结论包装成营销话术。No manufactured anxiety. Our products do not pass judgement on anyone's body, do not use scores to create pressure, and do not dress health claims up as marketing.
• 缺数据就说缺数据。当传感器或授权无法提供可靠数据时，我们降级展示或直接留白，绝不用估算值填补空缺。Missing data is shown as missing. When sensors or permissions cannot supply reliable data, we degrade the display or leave it blank. We never fill the gap with an estimate.
• 核心功能不设收费墙。帮助用户改变作息的完整循环始终免费；付费只用于购买记录、归档与表达上的增强。No paywall on the core loop. The complete loop that helps someone change their sleep is always free. Paid tiers exist only for enhancements to archiving, records and self-expression.
• 健康数据属于用户。睡眠与健康数据默认只保存在用户自己的设备上，我们不建立以此为目的的服务器画像。Health data belongs to the user. Sleep and health data stay on the user's device by default. We do not build server-side profiles from it.
