Description

TyphoonEye is a lightweight, open-source real-time typhoon tracking and weather alert app for Android.

Features:
• Live typhoon tracking with interactive MapLibre maps
• Historical tracks, forecast paths, and 7/10/12-level wind radii by quadrant
• Optional distance-based emergency alerts (needs location permission)
• Material Design 3, dynamic color, light/dark theme, multiple languages
• Clearly labeled sample data you can open when live data can't be loaded

Network note:
Typhoon data comes from third-party weather APIs (QWeather / Juhe) and is fetched through TyphoonEye's own relay server on Cloudflare. The API keys live only on the relay; the app contains none. The relay uses your IP address for rate limiting and does not store it. Your location is never sent to the relay: warnings near you are matched on your device and currently cover coastal areas only. Basemap tiles come from OpenFreeMap (OpenStreetMap data). Optional mainland China basemap tiles may use Amap. No ads or analytics.

This is not an official meteorological app. In an emergency, always follow your local meteorological authority.

F-Droid builds update through the F-Droid client (no GitHub APK sideload).

What’s new (1.3.1)

• Unsupported system languages now fall back to English instead of Chinese.
• Live typhoon data works right after install, with no API key needed. It is fetched from third-party providers through TyphoonEye's own relay server.
• Your location is not sent to the relay. Warnings near you are matched on your device and cover coastal areas only.
• Data is cached to cut network requests, and storms with no new observation for 24 hours are no longer shown as active.
