Strike Weather
Last updated: October 11, 2026
Strike Weather shows you the weather. It has no accounts, no ads and no analytics, and the developer runs no server that receives your data.
What the app uses
Your location. With your permission, the app uses your location while it is open to get the forecast for where you are. Your coordinates, rounded to about 10 meters, are sent to the weather service you have chosen in Settings to fetch the forecast: Apple Weather, the National Weather Service (US), Environment and Climate Change Canada, Germany's Deutscher Wetterdienst (through Bright Sky), Sweden's SMHI, the Finnish Meteorological Institute, MET Norway, or, with your own key, Tomorrow.io, OpenWeather or WeatherAPI.com. The default is Automatic: it uses Apple Weather. If Apple Weather can't be reached, it uses the official service for the country you're in, which the app works out on your phone from rough outlines of each country (a place elsewhere is never sent to them), and then MET Norway. If you have Strike+ and choose the Strike Select (beta) source, each refresh sends the same rounded coordinates to the official national weather service for that country (where one is built in), Apple Weather and MET Norway at once, and combines their answers on your device. When the National Weather Service is providing your forecast, the name of the nearest town (not your coordinates) also goes to the US Environmental Protection Agency for its UV index forecast. Your location is not sent anywhere else. The app keeps your last position, rounded to about a mile, on your device only, so the widgets still work when they can't find you; it is cleared if you turn off the app's location access, and it is never synced.
Rain alerts (optional). If you turn on Rain alerts, the app remembers your last position, rounded to about a mile, on your device only, so it can check for rain when the app is closed. It is deleted when you turn Rain alerts off, and it is never sent to iCloud. If Rain alerts are on, the app also keeps the next few hours' chance of rain (times and percentages only, no location) on your device for up to three hours, so it can check its short-range rain forecast against the hourly forecast when the app is closed. It is never sent anywhere or synced.
The rain and snow Live Activity (optional, on by default). While rain or snow is happening or due within the hour where you are, the app can show a Live Activity on your Lock Screen and in the Dynamic Island. It keeps a position rounded to about a mile on your device while the activity is active, and there is no push server: it only updates while the app itself is able to run, and it never leaves your device. The on-or-off preference syncs like your other settings; the position does not.
Places you search for. What you type in Search is sent to Apple Maps to complete place names. The last six places you opened from Search are kept on your device so they're there next time; swipe one away or tap Clear to remove them. If you save a place as a Favorite, its name and coordinates are kept so it appears next time — and, like your other preferences, that syncs between your devices through your private iCloud account. If you set a home address in Settings, its name, the address text and its coordinates are saved on your device and synced the same way. They are never sent to us; the weather service only receives the coordinates when you look at the weather at home. You can remove the address in Settings, or delete all iCloud data there.
Radar and maps. Local radar decodes NEXRAD data from NOAA's Open Data (NODD) on AWS on your device, for the site nearest you or one you pick by hand; that request tells NOAA/AWS which radar site and product you're asking for. The wider radar map instead uses NOAA's MRMS mosaic (via nowCOAST) for the US and the Americas, Environment and Climate Change Canada for Canada, or the Deutscher Wetterdienst for Germany, whichever covers the map area you're viewing — that service sees the map area, not who you are. The Day and Week forecast ranges work the same way, using NOAA's HRRR model (also NODD on AWS) for the next day in the US, and NOAA's GFS model (also on AWS) elsewhere and for the week ahead. Lightning, satellite, storm-cell tracking and warning layers come from NOAA (nowCOAST and the National Weather Service); tropical storms come from the National Hurricane Center (NOAA), which is asked for the active storms and never sent your location; the Wildfires layer comes from NASA FIRMS; the Burn Bans layer comes from the state forestry agencies that publish county burn bans (the Tennessee Division of Forestry, Texas A&M Forest Service, the Florida Forest Service, Oklahoma Forestry Services, the Mississippi Forestry Commission, the Arkansas Department of Agriculture Forestry Division and the Washington Department of Natural Resources) and, for Wyoming, the Bureau of Land Management's map of county fire restrictions with county outlines from the US Census Bureau, which are asked for a state's list of counties (or Washington's fire danger areas), never your location, and only for states the map area you're viewing touches or, with Strike+, the state of the place the weather page is showing (which county it's in is worked out on your device); the Wind layer comes from NOAA's GFS model on AWS; the Smoke layer comes from NOAA's HRRR-Smoke model, also on AWS. Each of these sees only the map area or radar site involved, never your identity. Tapping the map with Warnings on sends that point to the National Weather Service. Tapping a county with Burn Bans on is answered on your device and sends nothing. Whether a storm cell is heading toward your place is worked out on your device, and the radar site markers come from a list built into the app, so neither sends your location anywhere. Maps and place names come from Apple Maps.
Time Machine and rain heads-ups. The place's coordinates and the date you pick are sent to NASA's POWER service for the Time Machine. The rain heads-up banner and Rain alerts use MET Norway's hourly rain forecast, which receives your coordinates rounded to about 10 meters (and Apple's minute-by-minute forecast, when Apple Weather or Automatic is your source).
Ask (beta, optional). If you have Strike+ and turn on Ask (beta) in Experimental, your questions and the answers are handled by Apple Intelligence on your device and aren't sent anywhere. To answer, Ask uses data the app already gets in the same ways: the forecast, the radar around the place and the burn bans for its state. If a question names a place, just that place's name is sent to Apple Maps to find it, as in Search. For a question about a past day, the app sends that place's coordinates and the date to NASA's POWER archive, as the Time Machine does, or, for the last two days, the rounded coordinates and the date to Apple Weather. You can also talk to Ask (beta): only while its talking screen is open, the app uses your microphone to hear your question, and Apple's speech recognition turns it into text on your device. Your voice isn't recorded, kept or sent anywhere. The answer is read aloud by your device's built-in voice, also on the device.
Home Screen and Lock Screen widgets (optional). If you add a Strike Weather widget and allow it to use your location, the widget asks iOS for your location each time it refreshes and handles it exactly as the app does: your coordinates, rounded the same way, go to the weather service you've chosen (and to MET Norway for the short-range rain forecast, and to Apple for its minute-by-minute forecast when Apple Weather or Automatic is your source), and your location is not stored. If a widget can't get a fresh location, it uses the last position the app kept (described above) or your home address; if you've told iOS not to let widgets use your location, it uses only your home address. The last weather and radar a widget showed are kept on your device only, so it has something to show if a refresh fails. The radar widget instead fetches the same local or mosaic radar image described above, for the area around your location. So it can show what you've chosen, a widget reads your temperature unit, weather source and any Tomorrow.io, OpenWeather or WeatherAPI.com key you've added — kept on your device only, through a shared App Group and Keychain group that your location is never placed in.
Apple Watch (optional). With Strike+, the Strike Weather app on Apple Watch and its complications ask the watch for your location, with your permission, and handle it the same way: your rounded coordinates go to the weather services Automatic uses (described above) and to MET Norway for the short-range rain forecast, and your location is not stored. The watch reads your temperature unit, home address, Favorite places and whether you have Strike+ from your private iCloud account, where your iPhone keeps them.
Strike+ and tips (optional). Strike+ and the Tip Jar's tips are bought through Apple's App Store. Apple handles the payment; the developer never sees your name, Apple Account or payment details. To know whether Strike+ is on, the app asks the App Store on your device, and keeps the answer (a yes or no) on your device and in your iCloud key-value storage, so your Apple Watch can see it. It also asks the App Store which version of the app you first downloaded, to give earlier users three months with the features that were free before Strike+, and keeps the date those months began on your device and in your iCloud key-value storage, so they aren't started over. None of this is sent to the developer or anyone else. Tips don't unlock Strike+.
Feedback, reviews and the beta. Request a Feature and Report a Bug open forms on Tally in your browser, Rate Strike Weather opens the App Store, and Join the Beta opens TestFlight. The app sends them nothing. Anything you type into a form goes to Tally and to the developer, and each service has its own privacy policy.
Your own API keys (optional). If you choose Tomorrow.io, OpenWeather or WeatherAPI.com, you paste your own free API key. It is kept in your device's Keychain (this device only) and is sent only to that service.
Settings sync. Your preferences — temperature unit, weather source, where the weather page opens, map layers and your favorite layers, the radar's wind style, radar product and site, the rain and snow Live Activity on-off, Rain alerts on or off and their timing, your saved Favorite places, your home address, the achievements you've unlocked and your progress toward them (saved as the time each was unlocked), which Home Screen sections you show and their order, the Experimental switch, and Ask (beta)'s voice and whether its tab shows — sync between your devices through your private iCloud account. Your location, recent searches and API keys are never synced. To remove it all, use Settings › Delete iCloud Data: it deletes your synced preferences, home address, Favorite places and achievements from your iCloud account and puts the app back to its defaults on that device, and your other devices reset the next time they sync. Your API keys stay in the Keychain.
What the app does not do
It does not track you, build a profile, show ads, use analytics or crash-reporting services, or share your data with anyone other than the weather and radar services above, which receive only what is described here. Each of those services has its own privacy policy.
Children
The app is suitable for all ages and collects no personal information about anyone.
