What it does
Weather apps got slow, loud
and crowded. This one isn't.
-
Your day at a glance
The current temperature, a plain-language briefing, a patio-work index (can you take the laptop outside?), a weekend outlook, and a note when the temperature swings hard.
-
Live radar
NOAA NEXRAD radar across the contiguous US: the last 50 minutes in 5-minute frames. Outside the contiguous US, Stratus falls back to RainViewer radar.
-
Widgets
19 home screen widgets (hourly, rain, pollen, patio, wind, UV, sun, moon and more), in light and dark, with Material You colors.
-
Status bar temperature
The current temperature as a number in your status bar, sized to match the clock.
-
Pixel Watch
Nine tiles and eight watch-face complications.
-
Alerts without the noise
Rain alerts only when rain will reach your location soon, and at most one every two hours. US severe-weather warnings come straight from the National Weather Service.
-
Pollen
Tree, grass and weed levels from Google's Pollen API. US coverage only.
Screens
On the phone, and on the wrist.
Data sources
Where the weather comes from.
- Open-Meteo: forecast, geocoding and air quality
- NOAA / National Weather Service: US severe-weather alerts
- Iowa Environmental Mesonet: NOAA NEXRAD radar tiles
- RainViewer: radar outside the US
- Google Pollen API: pollen levels (US)
- Esri: map basemap
Privacy Policy
Your location goes to the weather.
Nowhere else.
What Stratus collects
Location. Precise or approximate location, only while you use the app or when it refreshes in the background, so it can fetch the weather where you are. You can search for a city instead. Location permission is requested at runtime, and Stratus works without it.
Nothing else. No account, no name, no email, no advertising ID, no contacts and no files.
Where your location goes
These third-party services receive your coordinates, a city name or the map area you are viewing, so they can answer the request.
| Service | Receives | Purpose |
|---|---|---|
| Open-Meteo | Coordinates or city name | Forecast, geocoding, air quality |
| National Weather Service (api.weather.gov) | Coordinates | Severe-weather alerts |
| Iowa Environmental Mesonet (NOAA NEXRAD) | Map tile coordinates (the area you are viewing) | Radar |
| RainViewer | Map tile coordinates | Radar outside the US |
| Esri | Map tile coordinates | Map basemap |
| Google Pollen API (US) | Coordinates | Pollen levels |
Like any web request, these services also see ordinary network metadata such as your IP address and the time of the request. Stratus sends them no identifier tied to you, and Applied Flux runs no server that receives your location. Each service's own policy applies to what it does with a request; the links above go to them.
What stays on your device
Saved locations, settings and cached forecasts live in the app's local database. A Pixel Watch syncs with the phone app through Google Play Services; that sync is device to device.
What Stratus does not have
No advertising, no analytics software, no crash-reporting software, no tracking, and no sale or sharing of data for advertising. Google Play itself may collect install and crash statistics under Google's policy.
Notifications
Rain, pollen and severe-weather notifications are optional. Permission is requested at runtime, and each category can be turned off.
Children
Stratus is not directed at children under 13, and it collects nothing from anyone.
Retention and deletion
Nothing is stored on a server, so there is nothing to delete remotely. Uninstalling the app removes all of its local data.
This website
The statements above describe the Stratus apps. This page sets no cookies and loads no analytics. It does load its typefaces from Google Fonts, so Google receives your IP address when the page loads. The rest of appliedflux.com uses Google Analytics to count visits, which is unrelated to the apps.
Changes
Changes are dated here. Material changes will be noted below the date at the top of this policy.

Stratus is built by one person, Ricky Cadden, under Applied Flux. Bug reports and feature arguments land in the same inbox, and I read them.
