世界画报隐私政策
最后更新：2026 年 11 月 8 日 · English
本政策说明 X WAVE Inc.（以下称“我们”）开发的 iOS App「世界画报」（以下称“App”）会处理哪些信息，以及如何处理。
我们不收集的信息
App 不需要注册或登录，我们不会要求你提供姓名、手机号、邮箱等个人信息，也没有自己的用户数据库。
只保存在你设备上的信息
- 看过的图集记录（用于显示“已看”）、朗读和每日提醒的开关设置。
- 浏览过的图片缓存，可以在 App 的设置里清除。
这些信息只存在你的 iPhone 上，不会上传给我们。删除 App 即会一并删除。
App 会申请的权限
- 添加照片到相册：仅在你点击“保存”时用于把照片存入相册。App 只申请“添加”权限，不会读取你相册里的照片。
- 通知：用于每天 9 点的本地提醒，由手机本地安排，不经过我们的服务器。
加载图片时连接的服务
App 会直接从以下来源加载图片和说明文字。和访问任何网站一样，这些服务会看到你的 IP 地址等网络请求信息，并按各自的隐私政策处理：
- 国家地理中文网图集接口（dili.bdatu.com）
- 必应每日一图（bing.com）
- NASA 图库（images.nasa.gov）
- Unsplash：列表请求经过我们部署在 Cloudflare 上的转发服务（api.worldpicture.xwave.app），图片从 images.unsplash.com 加载。转发服务只转发请求和缓存公开的图片列表，不记录、不保存任何用户信息；Cloudflare 作为服务提供方可能保留常规的访问日志。
广告
App 使用 Google AdMob 显示横幅广告。AdMob 可能收集设备和使用信息（例如设备型号、系统版本、大致位置、广告互动情况）用于投放和统计广告，详见 Google 的说明。App 不会请求“允许跟踪”权限，因此不会读取你设备的广告标识符（IDFA）。
统计和崩溃报告
App 使用 Google Firebase（Analytics、Crashlytics、Performance Monitoring）了解功能使用情况、App 运行性能和崩溃原因，用来改进 App。这些数据与设备上的随机标识符关联，不包含你的姓名或联系方式，详见 Firebase 的隐私说明。
内购
“请开发者喝一杯”通过 Apple 的 App 内购买完成。付款信息由 Apple 处理，我们拿不到你的付款方式或 Apple ID 信息。
儿童
App 不面向 13 岁以下的儿童，我们不会有意收集儿童的个人信息。
政策变更
本政策更新时，我们会修改本页并更新顶部的日期。

Privacy Policy
Last updated: November 8, 2026
This policy explains what information the iOS app World Picture (世界画报, "the app"), made by X WAVE Inc. ("we"), handles and how.
What we don't collect
The app has no sign-up or login. We don't ask for your name, phone number or email, and we don't run a user database.
What stays on your device
- Which galleries you have viewed, and your read-aloud and daily reminder settings.
- A cache of images you have viewed, which you can clear in the app's settings.
This stays on your iPhone and is never sent to us. Deleting the app deletes it.
Permissions
- Add to Photos: used only when you tap Save. The app asks for add-only access and cannot read your photo library.
- Notifications: used for the daily 9 AM reminder, scheduled locally on your phone.
Services contacted when loading images
The app loads images and captions directly from the sources below. Like any website, they see network information such as your IP address and handle it under their own privacy policies:
- National Geographic China gallery API (dili.bdatu.com)
- Bing image of the day (bing.com)
- NASA Image Library (images.nasa.gov)
- Unsplash: list requests go through our forwarding service on Cloudflare (api.worldpicture.xwave.app) and images load from images.unsplash.com. The forwarding service only relays requests and caches public photo lists; it does not log or store any user information. Cloudflare, as the provider, may keep standard access logs.
Advertising
The app shows banner ads from Google AdMob, which may collect device and usage information (such as device model, OS version, approximate location and ad interactions) to serve and measure ads. See how Google uses information. The app does not ask for tracking permission, so it does not access your device's advertising identifier (IDFA).
Analytics and crash reports
The app uses Google Firebase (Analytics, Crashlytics, Performance Monitoring) to understand feature usage, app performance and crashes so we can improve the app. This data is linked to a random identifier on the device and does not include your name or contact details. See Firebase privacy information.
In-app purchase
The tip purchase goes through Apple's In-App Purchase. Apple handles payment; we never receive your payment method or Apple ID details.
Children
The app is not directed at children under 13, and we do not knowingly collect personal information from children.
Changes
When this policy changes, we will update this page and the date at the top.
