Hurricane: Storm Tracker, from Delightful Data Studio. Effective October 10, 2026.

What the app shows

Public information from the National Hurricane Center (NHC), the National Weather Service (NWS), NOAA and the Joint Typhoon Warning Center (JTWC), with the time of each advisory or warning and where it came from. It is not an official product of any of these agencies, and they do not endorse it.

Your location

To tell you how far a storm is from you, and whether a watch or warning covers your place, the app sends that place's coordinates to our service. The service asks NHC, JTWC and, for places in the United States, the NWS about it and answers. We do not save the coordinates, build a profile, or link them to you. We do not log them: our logs leave out the part of a request that holds them.

Your saved places

Places you save stay on your phone. They are sent to our service when the app looks up a place, and, if you turn on alerts, kept for those alerts (below).

Alerts

If you turn on alerts, we keep a random install ID made by the app, your device's push token, the places you ask us to watch (coordinates rounded to about 1 km) and the alert setting you chose for each, only to send those alerts. A Live Activity on your Lock Screen uses its own push token, kept while it runs. Turning alerts off in the app removes them.

What we do not do

No ads, no tracking across other apps or sites, no selling data.
No account or sign-in.

Services we rely on

Our hosting provider and network provider handle requests and may keep short-lived technical logs. Maps come from Apple. Storm data comes from NOAA's National Hurricane Center and National Weather Service and from the Joint Typhoon Warning Center. Push alerts go through Apple Push Notification service. On our web pages, place search uses OpenStreetMap's Nominatim, maps use OpenStreetMap tiles, and the studio's site counts page views without cookies or IP addresses.
