隐私政策
生效日期：2026 年 11 月 13 日
止水（Stillwater）是一本情绪的航海日志。你写下的情绪是很私密的东西，所以我们的原则很简单：你的记录只属于你，只留在你自己的设备上。
1. 你的记录存在哪里
- 在网站 stillwater-9nm.pages.dev 上，你写下的每一笔记录（情绪、强度、身体感觉、发生了什么、想法等）只保存在你正在使用的浏览器里（浏览器本地存储）。
- 止水没有账号系统，不需要注册，也没有任何服务器保存你的记录。我们看不到，也拿不到你的记录。
- 这也意味着：清除浏览器数据、使用无痕模式、换手机或换浏览器时，记录可能会丢失。请用「航海日志」里的备份功能，自己保存一份。
2. 我们会收集什么
- 匿名访问统计。我们使用 Cloudflare Web Analytics 了解网站的访问情况，例如访问次数、页面浏览量、从哪个网站过来、所在国家或地区、浏览器和设备类型。它不使用 Cookie，不跟踪你在其他网站上的行为，也不用来识别你是谁；统计里不包含你写下的任何内容。
- 网站托管。网站由 Cloudflare Pages 提供。和所有网站一样，为了把网页送到你的设备、防范攻击，Cloudflare 会在传输过程中处理你的 IP 地址等网络信息。
- 字体。网页使用的字体来自 Google Fonts。加载字体时，你的浏览器会向 Google 的服务器发出请求，Google 因此会获得你的 IP 地址。
- 除此之外，我们不收集任何信息，也不使用广告或其他跟踪工具。
3. 存在你设备上的设置
语言、白天与夜晚、声音开关、分享卡片的版式、每日提醒的时间等偏好，同样只保存在你的浏览器里。
4. 分享、提醒与备份
- 分享卡片和宣传图都在你的设备上生成。只有你主动保存或分享时，图片才会离开你的设备，去哪里由你决定。卡片上只有情绪的名字（可以不写）、海况和画作，不包含你写下的其他内容。
- 每日提醒会生成一个日历文件，由你自己的日历 App 处理。
- 备份文件或复制出来的备份内容，由你自己保管。
5. 在 claude.ai 上使用止水
如果你在 claude.ai 上以 Claude Artifact 的形式打开止水，记录会保存在你自己的 claude.ai 账户中，由 Anthropic 按其隐私政策处理。只有当你主动点击「请 Claude 读一读这一周」时，这一周的记录才会发送给 Claude，只用于生成那一次的回看。
6. 你的权利
你可以随时在「航海日志」里编辑或删除任何一条记录；清除浏览器数据会删除全部记录。因为我们不保存你的记录，所以没有需要我们替你删除的数据。如果你对自己的信息有任何疑问，欢迎联系我们。
7. 儿童
止水不是为儿童设计的。我们不会有意收集任何人的个人信息，包括儿童。
8. 关于健康
止水帮助你看见自己的情绪规律，但它不是医疗或心理治疗服务，也不提供诊断。如果你正处在困难中，请看支持页上的心理援助热线。
9. 政策的变化
如果这份政策有变化，我们会更新本页，并修改上面的生效日期。将来推出 App 时，我们会在这里说明 App 的做法。

Privacy Policy
Effective 13 November 2026
Stillwater (止水) is a logbook for your feelings. What you write there is private, so our rule is simple: your entries belong to you, and they stay on your own device.
1. Where your entries live
- On the website stillwater-9nm.pages.dev, every entry you write (feelings, intensity, body sensations, what happened, your thoughts) is stored only in the browser you are using (its local storage).
- Stillwater has no accounts, needs no sign-up, and has no server that stores your entries. We cannot see them and we do not receive them.
- This also means entries can be lost if you clear your browser data, use a private window, or change phone or browser. Use Back up in the Logbook to keep your own copy.
2. What we collect
- Anonymous visit statistics. We use Cloudflare Web Analytics to understand how the site is used: number of visits and page views, the site you came from, your country or region, and your browser and device type. It uses no cookies, does not follow you across other sites, and is not used to identify you. Nothing you write is part of it.
- Hosting. The site is served by Cloudflare Pages. As with any website, Cloudflare processes network information such as your IP address to deliver the pages and protect the site.
- Fonts. The typefaces come from Google Fonts. When they load, your browser requests them from Google's servers, which therefore receive your IP address.
- Beyond this we collect nothing, and we use no advertising or other tracking tools.
3. Settings on your device
Your preferences, such as language, day or night, sound, share card layout and reminder time, are also kept only in your browser.
4. Sharing, reminders and backups
- Share cards and posters are made on your device. An image leaves your device only when you choose to save or share it, and you decide where it goes. A card shows only the name of the feeling (which you can leave off), the sea state and the painting, never the rest of what you wrote.
- The daily reminder is a calendar file handled by your own calendar app.
- Backup files and copied backups are kept by you.
5. Using Stillwater on claude.ai
If you open Stillwater on claude.ai as a Claude artifact, your entries are saved in your own claude.ai account and handled by Anthropic under its privacy policy. A week's entries are sent to Claude only when you tap “Ask Claude to read this week”, and only to write that reading.
6. Your choices
You can edit or delete any entry in the Logbook at any time; clearing your browser data deletes them all. Because we do not keep your entries, there is nothing for us to delete on your behalf. If you have any question about your information, please write to us.
7. Children
Stillwater is not designed for children. We do not knowingly collect personal information from anyone, children included.
8. About health
Stillwater helps you notice your own patterns. It is not a medical or therapy service and does not diagnose anything. If you are going through a hard time, the support page lists crisis lines.
9. Changes
If this policy changes, we will update this page and the date above. When a Stillwater app is released, this page will also describe how the app handles your data.
