Privacy Policy — J霧霾 (JPM)
Last updated: 2026-09-06 · applies to the Android app
“J霧霾” (package com.jintin.pm25.tw)
J霧霾 shows publicly available air-quality readings for Taiwan. This page
describes exactly what data the app handles, which is deliberately little.
Data that stays on your device
- Favorites, alert settings, theme — stored locally,
never uploaded, removed when you uninstall the app.
- Location — if you grant the permission, your location
is used on the device only to center the map on nearby stations. It is
never sent to us and never attached to ad requests. The app works fully
without it.
Data collected by third-party services
The app includes the following Google services, which collect data as
described in the
Google Privacy Policy:
- Google AdMob (advertising) — collects the advertising
ID and device information to serve and measure ads. In the EEA, UK and
Switzerland, ads are only requested after you answer the consent form
(Google UMP). You can reset or delete your advertising ID in Android
settings, and remove ads entirely via the in-app purchase. See
AdMob ad
technology providers.
- Firebase Crashlytics & Performance — collect crash
logs and app diagnostics so failures can be found and fixed.
- Firebase Analytics — collects aggregate usage
statistics (e.g. which screens are opened).
- Google Play Billing — processes the “remove ads”
purchase. We never see your payment details.
Air-quality data
Readings and forecasts are fetched from Taiwan’s Ministry of Environment
open-data platform. These requests carry no account and no personal data.
What we do not do
- No accounts, no sign-in, and no server of our own storing personal data.
- We do not sell data, and we share nothing beyond the services listed above.
- The app is not directed at children under 13.

J霧霾顯示台灣公開的空氣品質資料。本頁完整說明 App 處理哪些資料——刻意保持得很少。
只留在你裝置上的資料
- 最愛站點、警示設定、主題 — 僅儲存在本機,不會上傳,解除安裝即刪除。
- 定位 — 若你授予權限,定位只在裝置上用來將地圖置中到附近測站,
不會傳送給我們,也不會附加在廣告請求上。不授權也能完整使用。
第三方服務收集的資料
App 內含以下 Google 服務,其資料收集方式見
Google 隱私權政策:
- Google AdMob(廣告)— 收集廣告 ID 與裝置資訊以放送及評估廣告。
在歐洲經濟區、英國與瑞士,必須先回覆同意表單(Google UMP)才會請求廣告。
你可以在 Android 設定中重設或刪除廣告 ID,也可以透過 App 內購買完全移除廣告。
- Firebase Crashlytics 與 Performance — 收集當機記錄與診斷資料,用於修復問題。
- Firebase Analytics — 收集彙總使用統計(例如哪些畫面被開啟)。
- Google Play 帳款服務 — 處理「移除廣告」購買,我們不會看到你的付款資訊。
空氣品質資料
測站讀數與預報取自環境部開放資料平台,這些請求不含帳號或任何個人資料。
我們不做的事
