## Undercast Weather Aether Description
UndercastWeather Aether delivers National Weather Service forecasts alongside on-device, model-enhanced predictions you can compare side by side.

The idea is simple: you should be able to see the official forecast AND a smarter interpretation of it — without giving up your privacy.

WHAT MAKES UNDERCAST DIFFERENT
• Dual-mode forecasts — switch between raw NWS data and Aether-enhanced predictions with a tap
• On-device learning — Aether refines its forecasts using local signals; nothing leaves your device
• Severe weather Live Activities — Tornado, Thunderstorm, Flood, and other warnings appear on your Lock Screen and in the Dynamic Island the moment they're issued, with hazard-specific icons
• Astronomical data — sunrise, sunset, moon phase, and twilight times sourced from the U.S. Naval Observatory
• Searchable — find any U.S. location by ZIP code, city, or state, no location sharing required

BUILT FOR APPLE PLATFORMS
Native experiences on Mac, iPhone, and iPad — with a Home Screen widget for at-a-glance conditions.

ONGOING UPDATES
UndercastWeather regularly updates Aether to improve accuracy, performance, and features.

PRIVACY FIRST
Aether's learning happens on device. Your trained data never leaves your devices — with optional iCloud sync, it moves only between your Apple devices through your private iCloud account. You don't need to share your location to use the app, and we don't collect telemetry on your forecast usage.

Our apps do not use third-party analytics, advertising SDKs, tracking SDKs, data brokers, or third-party service connections. We encourage every user to turn on Apple’s App Privacy Report to see this for themselves.
To enable App Privacy Report on iPhone or iPad, open Settings > Privacy & Security > App Privacy Report > Turn On App Privacy Report. After you use the app for a while, iOS will show the network domains contacted by the app.
For our apps, expected network activity should be limited to Apple-operated services needed for normal App Store, iCloud, device, or system functionality. In our weather app, you may also see direct connections to official weather or environmental data sources, such as NOAA, EPA, or similar public data originators used to provide the requested forecast, alert, air-quality, or environmental information.

We believe privacy claims should be inspectable, not merely promised.

NOTE
Only locations within the United States are supported, as Aether is trained (on device) on data sourced by you from the National Weather Service.
