Privacy Policy

Last updated: 20 September 2026

Dayworld is a personal daily-tracking app — meditation, focus sessions, daily to-dos, and planetary positions. It is designed to be private by default, and this site is built the same way.

What Dayworld stores

Everything you enter in Dayworld — meditation minutes, focus sessions and reflections, focus tags, and daily to-dos — is stored locally on your device, in the app's own storage area. The developer operates no server for your data and has no access to any of it.

Optional Notion sync

Dayworld can optionally sync your entries to a Notion database that you own. This happens only if you paste your own Notion API key and database ID into Settings.

• Data travels from your device to Notion's API under your Notion account. The developer is never in the path and never sees it.
• Your Notion credentials are stored only on your device, in the app's private preferences.
• Notion's handling of that data is governed by Notion's privacy policy.
• Sync is entirely optional. Without credentials the app works fully offline and keeps everything on the device.

Optional Apple Health and Apple Calendar

On iPhone, Dayworld can optionally copy two kinds of record into Apple's own apps on the same device. Both are off until you turn them on in Settings, each is a separate switch, and iOS will ask your permission the first time. The app is the record and these are copies of it — nothing in Dayworld depends on what is in them.

• Apple Health. A finished meditation is written as Mindful Minutes — its start and its length, and nothing else. Dayworld asks Health for permission to write that one type and nothing else, and never reads any of your health data. You will not see a prompt asking to read it, because the app never asks. (One piece of small print, so nothing here is a surprise: iOS requires any app with the Health capability to declare a reason for reading even when it requests none, so the app carries one. It says that nothing is read, and it is never used.)
• Apple Calendar. A finished focus session is written as an event in a calendar named Dayworld that the app makes for itself. Your existing calendars are never read and never changed, and deleting that one calendar removes every event the app has ever written. iOS grants calendar access as a single permission rather than a write-only one, so the app holds more access than it uses: it needs to be able to find and make its own calendar, and that is all it does with it.
• Both stay on your device, in Apple's own storage. The developer is not in the path, sees none of it, and nothing is sent to any server. What Apple does with it is governed by Apple's privacy policy.
• You can withdraw either permission at any time in iOS Settings, or turn the switch off in Dayworld. Records already copied stay in Health and Calendar until you delete them there.

This website

dayworld.space is a set of static files. It has no accounts, no sign-in, no analytics, no advertising, no tracking pixels and no third-party scripts — nothing on the page is loaded from anywhere but this domain.

• No cookies. The site sets none.
• The timers record nothing. The meditation and focus timers on the home page run entirely in your browser. The timeline a finished focus session lands on — its time, its icon, whatever you typed into it — lives in that page and nowhere else. Nothing is saved, sent, or counted, and closing the tab ends it.
• Your birth details are not kept. The chart section asks for a date, a time and a place. They are used to work out the chart, on your device, and are thrown away the moment you close or reload the page. They are never sent anywhere, and the place list they search is a file that ships with the site — not a lookup service.
• The sky is computed on your device. The planetary positions are worked out by an ephemeris shipped inside the page. It uses the date, nothing else — no location, no requests, no lookups.
• One thing is remembered: whether you chose Chinese or English, stored in your browser's own local storage so the site opens in the same language next time. It never leaves your browser. Clearing your browser's site data removes it.
• Like every web server, the machine serving this site may keep ordinary request logs (IP address, time, page requested) for security and troubleshooting. They are not used to build a profile of you and are not shared.

What Dayworld does not do

• No accounts, no sign-in.
• No analytics, no advertising, no tracking of any kind.
• No third-party SDKs beyond the open-source Capacitor app framework.
• No data is collected by, shared with, or sold to the developer or anyone else.

Children

Dayworld is not directed at children under 13, and collects no data from anyone — including children.

Data deletion

Deleting the app deletes all locally stored data. If you used Notion sync, your synced entries live in your own Notion database — delete them there if you wish. If you used Apple Health or Apple Calendar sync, those copies live in Health and in the Dayworld calendar respectively; deleting that one calendar removes every event the app wrote.

隐私条款

最后更新：2026 年 9 月 20 日

DayWorld 是一个私人的日常记录应用 —— 冥想、专注、每日待办与行星位置。 它默认就是私密的，这个网站也是按同样的原则做的。

DayWorld 存了什么

你在 DayWorld 里输入的一切 —— 冥想时长、专注记录与感想、专注标签、每日待办 —— 都只存在你自己的设备上，在应用自己的存储区里。 开发者不运行任何服务器来存放你的数据，也无法访问其中任何内容。

可选的 Notion 同步

DayWorld 可以选择性地把你的记录同步到你自己拥有的 Notion 数据库。 这只在你把自己的 Notion API key 和数据库 ID 填进设置之后才会发生。

• 数据从你的设备直接发往 Notion 的 API，走的是你自己的 Notion 账号。 开发者不在这条路径上，也看不到它。
• 你的 Notion 凭据只存在你的设备上，在应用的私有偏好设置里。
• Notion 如何处理这些数据，适用 Notion 的隐私政策。
• 同步完全可选。不填凭据，应用可以完全离线使用，所有东西都留在设备上。

可选的苹果健康与苹果日历

在 iPhone 上，DayWorld 可以选择性地把两类记录拄一份到同一台设备的苹果自带应用里。 两者默认都是关的，要在设置里自己打开，各自一个开关，第一次打开时 iOS 会向你询问权限。 应用本身才是记录，那边只是副本 —— DayWorld 不依赖那里面的任何东西。

• 苹果健康。一次完成的冥想会被记为「正念分钟」—— 只有开始时刻和时长，没有别的。DayWorld 只向健康申请写入这一种数据的权限， 不申请其他任何类型，也从不读取你的任何健康数据。 你不会看到请求读取的弹窗，因为应用从没请求过。（一句小字，免得你日后觉得意外： iOS 要求任何带有健康能力的应用都声明一个读取理由，即使它从不申请读取， 所以应用里带了一条。它写的是“不读取任何数据”，并且从不会被用到。）
• 苹果日历。一次完成的专注会写成一条事件，放在应用自己新建的、 名为 Dayworld 的日历里。你原有的日历不会被读取，也不会被修改； 删掉那一个日历，就等于删掉应用写过的全部事件。iOS 的日历权限是一整份而不是“只写”的， 所以应用拿到的权限比它用到的多：它需要能找到和新建自己的那个日历，也只用来做这件事。
• 两者都留在你的设备上，存在苹果自己的存储里。开发者不在这条路径上， 看不到其中任何内容，也没有任何东西被发往服务器。苹果如何处理这些数据，适用 苹果的隐私政策。
• 你可以随时在 iOS 设置里收回任一权限，或者在 DayWorld 里把开关关掉。 已经拄过去的记录会留在健康和日历里，直到你在那边删掉它们。

关于这个网站

dayworld.space 是一组静态文件。没有账号、没有登录、没有统计分析、没有广告、 没有追踪像素、没有第三方脚本 —— 页面上的一切都只从本域名加载。

• 不使用 Cookie。本站一个都不设置。
• 计时器不记录任何东西。首页的冥想与专注计时器完全在你的浏览器里运行。 一次专注结束后落在时间线上的内容 —— 时刻、图标、你写下的字 —— 只存在于那个页面里。 没有任何东西被保存、上传或统计，关掉页面就结束了。
• 你的出生信息不会被保留。星盘那一栏会问你出生日期、时间和地点。 它们只用来在你的设备上算出这张盘，页面一关或一刷新就没了。它们不会被发往任何地方； 搜索出生地用的城市表是随网站一起下发的文件，不是查询服务。
• 星野是在你的设备上算出来的。行星位置由页面内置的星历表计算， 只用到日期，不用别的 —— 不需要定位，不发任何请求。
• 只有一件事会被记住：你选的是中文还是英文，存在浏览器自己的 local storage 里，好让下次打开时还是同一种语言。它不会离开你的浏览器； 清除浏览器的站点数据即可删除。
• 和所有 Web 服务器一样，提供本站的服务器可能会保留常规的访问日志 （IP 地址、时间、请求的页面），用于安全与排查故障。它们不会被用来建立关于你的画像， 也不会被分享。

DayWorld 不做的事

• 没有账号，不需要登录。
• 没有统计分析、没有广告、没有任何形式的追踪。
• 除了开源的 Capacitor 应用框架之外，不引入任何第三方 SDK。
• 没有任何数据被开发者或其他任何人收集、共享或出售。

儿童

DayWorld 并非面向 13 岁以下儿童，并且不从任何人（包括儿童）收集数据。

删除数据

删除应用即删除全部本地数据。如果你用过 Notion 同步， 同步过去的内容在你自己的 Notion 数据库里 —— 需要的话请在那里删除。 如果你用过苹果健康或苹果日历同步，那些副本分别在健康里和名为 Dayworld 的日历里；删掉那一个日历，就删掉了应用写过的全部事件。
