StayUp Terms of Use
Last updated: October 8, 2026
1. Acceptance
By downloading or using StayUp (今晚别熬) you agree to these terms. If you do not agree, please do not use the app.
2. What StayUp is
StayUp is a local-first routine planning aid for people with a fixed wake time. It turns your wake anchor, seven-day sleep debt and recent sleep into tonight's verdict, a latest bedtime and a short explanation, and it shows the weights, thresholds and reasons behind the result.
3. Not medical advice
StayUp is not a medical device and does not provide medical advice, diagnosis, treatment or monitoring. Its verdict, latest bedtime and sleep-debt figures are estimates for general scheduling guidance only, based on the records available at that moment. Do not use the app to decide whether to take or stop medication, or in place of advice from a qualified professional. If you have a health concern, contact a qualified professional.
4. Your responsibilities
You are responsible for the records you enter, for the permissions you grant, and for how you act on the app's output. Do not rely on StayUp as the only basis for safety-critical decisions, for care of a child or another person, or for any decision with consequences you cannot accept. You agree not to reverse engineer, redistribute, resell or misuse the app, and not to use it in a way that breaks applicable law.
5. Apple platform dependencies
StayUp depends on Apple system services including Apple Health (read-only), the Calendar framework (read-only), local notifications, the app group container, WatchConnectivity, App Intents and — when you enable it and your device supports it — Apple's on-device Foundation Models. Availability, accuracy and behaviour of those services are controlled by Apple, by your device and by your settings. If a permission is declined or a service is unavailable, the app falls back to manual entry; some features may then be reduced.
6. Local data, backup and export
Your records and settings are stored only on your device. You can remove a night, reset the personal baseline, or export a CSV through the iOS share sheet. You are responsible for your own backups. Deleting the app, resetting the device, or a storage failure can remove local data, and the developer cannot restore data that was never transmitted to a server.
7. Free app, pricing and purchases
The current release is free and has no in-app purchases, subscriptions, paywall or paid feature unlock. If a future version introduces paid content, the price and terms will be shown in the App Store before you buy, and Apple's App Store purchase terms will apply.
8. Availability, updates and termination
The app is offered as-is and may change or be discontinued. Updates may add, change or remove features, and are delivered through the App Store. You may stop using the app at any time by deleting it.
9. Disclaimer and limitation of liability
To the fullest extent permitted by law, the app is provided without warranties of any kind, express or implied, including fitness for a particular purpose or accuracy of any figure. The developer is not liable for indirect, incidental or consequential loss, or for loss of data, sleep, opportunity or profit, arising from use of the app. Nothing in these terms limits rights you have under mandatory consumer law in your jurisdiction.
10. Changes
These terms may be updated when the app changes. The current version is always the one published on this page, and material changes will be reflected here before the release that requires them.
11. Contact
Questions about these terms can be sent to [email protected].
今晚别熬 StayUp 用户协议
更新日期：2026 年 10 月 8 日
一、协议接受
下载或使用 StayUp（今晚别熬）即表示你同意本协议。如果你不同意，请不要使用本应用。
二、产品用途
今晚别熬是一款本地优先的作息规划工具，面向有固定起床时间的用户。它根据你的起床锚点、七天睡眠负债和最近一晚睡眠，给出今晚结论、最迟入睡时间与简短说明，并展示结论用到的权重、阈值和原因。
三、非医疗建议
今晚别熬不是医疗器械，不提供医疗建议、诊断、治疗或监测。它的结论、最迟入睡时间与睡眠负债都是基于当时可用记录的估计，仅用于一般作息参考。请勿用它决定是否服用或停用药物，也不要用它替代专业人士的建议。如有健康方面的疑虑，请联系专业人士。
四、你的责任
你需要对自己录入的记录、授予的权限以及如何采用 App 的结论负责。请勿把今晚别熬作为安全攸关决策、照护儿童或他人的唯一依据，也不要用于你无法承担后果的决策。你同意不对本应用进行逆向工程、再分发、转售或滥用，也不以违反适用法律的方式使用本应用。
五、Apple 平台依赖
今晚别熬依赖 Apple 的系统服务，包括 Apple 健康（只读）、日历框架（只读）、本地通知、App Group 容器、WatchConnectivity、App Intents，以及在你开启且设备支持时的 Apple 端侧基础模型。这些服务的可用性、准确度与行为由 Apple、你的设备与你的设置决定。如果某项权限被拒绝或服务不可用，App 会回落到手动记录，部分功能可能因此减少。
六、本地数据、备份与导出
你的记录与设置只保存在本机。你可以移除某一晚、重置个人基线，或通过 iOS 分享面板导出 CSV。请自行负责备份。删除 App、重置设备或存储故障都可能导致本地数据丢失，而开发者无法恢复从未上传到服务器的数据。
七、免费应用、定价与购买
当前版本免费，没有内购、订阅、付费墙或付费功能解锁。如果未来版本引入付费内容，价格与条款会在购买前的 App Store 页面中展示，并适用 Apple 的 App Store 购买条款。
八、可用性、更新与终止
本应用按现状提供，可能变更或停止提供。更新可能新增、调整或移除功能，并通过 App Store 交付。你可以随时删除 App 来停止使用。
九、免责声明与责任限制
在法律允许的最大范围内，本应用不提供任何明示或默示的保证，包括对特定用途适用性或任何数值准确性的保证。对于因使用本应用而产生的间接、附带或后果性损失，或数据、睡眠、机会、利润的损失，开发者不承担责任。本协议不限制你所在司法辖区强制性消费者法律赋予你的权利。
十、协议变更
当应用发生变化时，我们可能更新本协议。当前版本始终以本页面公布的版本为准；如需实质变更，我们会在需要该变更的版本发布前更新本页面。
十一、联系方式
如对本协议有疑问，请发送邮件至 [email protected]。
