The short version
DotWx has no accounts, no ads, no analytics, no tracking, and no third-party
SDKs. Your data never leaves Apple's platforms. We (the developer) run no
servers and receive none of your data.
What the app uses, and why
- Location (While Using, optional). Used on your device to
fetch the weather for where you are via Apple WeatherKit and to name your
current city via Apple MapKit reverse geocoding. Your coordinates are sent
only to these Apple services, never to us or any third party. You can deny
location and add cities manually instead.
- Saved cities & settings. Stored locally on your
device. If you enable iCloud Sync, they are stored in your private iCloud
key-value storage, readable only by your Apple account. Your
current-location city is never synced to iCloud.
- Apple Watch (optional). If you pair an Apple Watch, your
weather data (including your current-location city) and any custom glyph
edits are sent directly to your Watch via Apple's WatchConnectivity — a
device-to-device channel between your own devices. Nothing is sent to us
or any third party.
- Weather cache. A local copy of recent forecasts is kept
on your device (shared with the app's widgets) so widgets and offline views
work. The app also keeps a local per-city daily summary (up to about two
years) to draw the annual dot-matrix poster, and a 48-hour pressure log
for the barograph — both on your devices only.
- Notifications (optional). Rain alerts and the daily
briefing are scheduled locally on your device. No push servers are involved.
- Photo library (add-only, optional). Only if you choose
"Save Image" when exporting a weather card or poster. The app can add that
image; it cannot read your photos.
- Purchases. The one-time DotWx Pro unlock is processed
entirely by Apple's App Store (StoreKit). We never see payment details.
What we don't do
- No data collection, sale, or sharing with third parties.
- No advertising, no tracking across apps or websites (App Tracking
Transparency is not required because there is no tracking).
- No accounts — so there is nothing to register or delete on our side.
Data retention & deletion
All data lives on your device (and, if you enabled sync, in your private
iCloud). Deleting the app removes local data; you can clear synced data by
disabling iCloud Sync and deleting the app, or via iOS Settings → Apple
Account → iCloud. Weather data is provided by Apple Weather
(data source
attribution) under Apple's own privacy terms.

简要说明
DotWx 无账号体系、无广告、无统计分析、无跟踪、无任何第三方 SDK。
你的数据不会离开 Apple 平台。开发者不运营任何服务器,也不会收到你的任何数据。
App 使用哪些数据,为什么
- 位置(使用期间,可选)。仅在你的设备上用于通过 Apple
WeatherKit 获取所在地天气,并通过 Apple MapKit 反向地理编码得到城市名。
坐标只发送给上述 Apple 服务,绝不发送给开发者或任何第三方。你可以拒绝定位,改为手动添加城市。
- 已存城市与设置。存储在你的设备本地;开启 iCloud 同步后,
存入你的私人 iCloud 键值存储,仅你的 Apple 账户可读。当前定位城市永不参与 iCloud 同步。
- Apple Watch(可选)。配对手表后,天气数据(含当前定位城市)与你的自定义字形
经 Apple 的 WatchConnectivity 在你自己的设备之间直传到手表,绝不经过开发者或任何第三方。
- 天气缓存。近期预报的本地副本保存在设备上(与小组件共享),
用于小组件与离线展示;另在设备本地保留逐日天气摘要(至多约两年,用于年度点阵海报)与 48 小时气压日志(用于气压走纸)。
- 通知(可选)。雨警报与每日简报均为设备本地调度,不经任何推送服务器。
- 照片图库(仅添加,可选)。仅当你在导出天气卡片/海报时选择"存储图像"。
App 只能写入该图像,无法读取你的照片。
- 购买。DotWx Pro 一次性买断完全由 Apple App Store(StoreKit)处理,
开发者不接触任何支付信息。
我们不做的事
- 不收集、不出售、不与第三方共享任何数据。
- 无广告,不进行跨 App / 网站跟踪(因不存在跟踪,无需 App 跟踪透明度授权)。
- 无账号——因此也不存在需要注册或注销的内容。
数据保留与删除
所有数据仅存在于你的设备(以及你自己开启的私人 iCloud 同步)。删除 App 即删除本地数据;
可通过关闭 iCloud 同步后删除 App,或在 iOS 设置 → Apple 账户 → iCloud 中清除同步数据。
天气数据由 Apple Weather 提供(数据来源署名),
适用 Apple 自身的隐私条款。
变更
如本政策发生变更,更新版本将发布于本页面并标注新的生效日期。
