Simply Radar shows public weather radar and works out when a storm you point at will reach a place you choose. There are no accounts, and we operate no server: the app talks directly to public government weather services and to Google, and nothing you do in it is sent to us.
Your location is used on your phone to place the target. It is sent to one outside service — the US National Weather Service, to fetch the warnings in force at that point — and to nobody else.
The app asks for precise location so the arrival time is measured to where you actually are. On the phone it is used for three things: centring the map, marking your position as the free-tier target, and the arrival calculation itself. You can decline; the map still works and you can move the target by hand (Premium) or use the demo storm.
What leaves the phone, and to whom:
| Sent | To | Why |
|---|---|---|
| Your position, rounded to about 10 m (four decimal places) | US National Weather Service (api.weather.gov) | To list the watches and warnings active at that point |
| The map area you are looking at | NOAA / National Weather Service radar image service | To fetch radar tiles for that area — this is where the map is pointed, not where you are |
| The map area you are looking at | Google Maps (base map) | To draw the streets and terrain under the radar |
| A place name you type into the target search (Premium) | Android's built-in geocoder, which Google operates on most phones | To turn "Tullahoma, TN" into a point on the map |
Nothing else is sent. There is no analytics, no crash reporting, and no telemetry of ours. The request to the National Weather Service identifies the app by name and gives our support address as the contact, as their API terms ask — it carries nothing about you.
Your location is never sent to Cypress Technology. We have no server to send it to.
The app opts out of Android's cloud backup and device-to-device transfer, so none of this is copied to your Google account. Uninstalling deletes all of it.
On the free tier the app displays one banner advertisement supplied by Google AdMob, and that SDK collects data. With Premium the advertising SDK is never started and none of the following applies.
| Data | Collected by | Purpose |
|---|---|---|
| Advertising ID (a resettable device identifier) | Google AdMob | Advertising, measurement, fraud prevention |
| Approximate location, derived from IP address | Google AdMob | Serving regionally appropriate ads |
| App interaction and diagnostic data | Google AdMob | Ad delivery and performance |
| Purchase status and transaction | Google Play | Processing and restoring your Premium purchase |
Google's handling of this is governed by the Google Privacy Policy. You can reset or delete your Advertising ID in Android Settings → Privacy → Ads. In the EEA, the UK and Switzerland the app presents a consent form on first launch, and you can change that choice later at Settings → Ad preferences.
Radar imagery is the National Weather Service's MRMS composite, served by NOAA. Watches and warnings come from the National Weather Service alerts API. Both are public US government services with their own availability; when they cannot be reached the app says so and keeps the last loop it has. Simply Radar is not affiliated with NOAA or the National Weather Service.
The app does not request background location, camera, contacts, microphone, storage, SMS or phone permissions.
Simply Radar is not directed to children and is not intended for anyone under 13. We do not knowingly collect information from children.
Because we hold no personal data about you, there is nothing for us to export or delete on request — but if you have a question, please write to us.
If this policy changes materially we will update the date at the top and, where the change affects how data is handled, note it in the app's release notes.
