Privacy policy

Effective October 18, 2026

HurriMap shows hurricane forecasts and warnings. It is built to need as little about you as possible: no account, no advertising, no analytics, and no tracking across other apps or websites. We do not sell or share your information.

Your place

You can set "My place" with a ZIP code, by pressing on the map, or with your device's location. Location is only read when you tap "Use my location." Your place is stored on your device so the app can show what each storm means there.

To work out those details, the app sends the place's coordinates to public government services: the National Weather Service (for your forecast office, local statements, weather radio stations and alerts) and NOAA's map services (for storm surge risk). Map tiles are loaded from mapping providers such as Esri, which see the area of the map you are viewing, as with any map app.

Storm data

The app, your watch and your widgets download forecasts, maps and storm information from hurrimap.com. These downloads are the same for everyone and contain nothing about you or your place.

Alerts

Alerts are designed so that we never learn where you are. If they're on, your phone subscribes, through Google's Firebase Cloud Messaging, to the National Weather Service forecast zone that contains your place (for example "FLZ151"), with a separate subscription for watches if you have Pro. When the National Weather Service issues a watch or tropical storm warning for that zone, our server sends one message to the zone, and Firebase delivers it to every phone following it, through Apple Push Notification service on iPhone.

Our server never receives your place, your zone, your device's push token or anything else that identifies you or your phone. To deliver messages, Firebase keeps your phone's push token, an app instance ID it creates and the zone your phone follows, under Google's privacy policy. HurriMap does not use Firebase for analytics or advertising.

Removing it: turn off alerts or remove your place in the app, and your phone stops following the zone. Uninstalling the app stops all notifications.

If you used version 1.0: its warning alerts registered your place (rounded to about 100 meters), a short label (such as "ZIP 33606"), its National Weather Service zones, your alert choices and a push token with our alert server. When you update the app, it deletes that registration from our server automatically. Turning off alerts or removing your place in version 1.0 deletes it too. When we retire the version 1.0 alert service, every remaining registration is deleted.

Apple Watch, Wear OS and widgets

Your place and settings are shared from your phone to your own watch and widgets on your devices. They download the same public storm data the app uses.

Subscriptions

HurriMap Pro is purchased through the App Store or Google Play. They process the payment; we never see your payment details. The app only checks whether a subscription is active.

Support messages

If you use the form on our support page, we store what you enter (your message, topic and device, and your name and email if you give them) on our server so we can read and answer it. We use it only for that. Messages are deleted after we've dealt with them, and in any case after one year.

To limit spam, the form counts messages per connection for one hour using a scrambled (hashed) form of your IP address; the address itself is not stored.

This website

hurrimap.com uses no cookies, analytics, advertising or third-party scripts or fonts. Like any website, it is delivered through our hosting provider and Cloudflare, whose servers keep standard technical logs (such as IP address, browser type and pages requested) for security and reliability.

Children

HurriMap is a general audience app and is not directed to children under 13. We do not knowingly collect information from children.

Questions and requests

To ask about your information or have it removed, use the form on our support page and choose the "Privacy" topic.

Changes

If this policy changes, we will update this page and its effective date.
