Guam Life
Last updated 6 November 2026
Guam Life is the island's magazine, events guide and weather app, published by Kar Kulture. This policy describes exactly what the app does with information, and it is written from the app's actual behaviour rather than from a template. The app works the same way on iPhone and Android; where the two differ, this policy says so.
The short version. There are no accounts. Guam Life is paid for by local businesses that advertise in it, but the ads are sold directly to those businesses and are the same for everyone — they are not targeted at you, and the app does not track you or use an advertising identifier. To tell advertisers how many people saw their ad, the app sends an anonymous count that carries no identifier and no location. Your location is used to fetch weather for where you are. The one thing our servers keep for your device is a push notification address, so that a change in Guam's Condition of Readiness can reach you.
If you allow it, the app takes a single location fix each time it refreshes the weather. There is no background location tracking. The coordinates are used to request the forecast, observations and tide predictions for your position, which means they are sent to the weather services listed under Services the app contacts.
Your location is never stored on our servers, never linked to an identity, never used to choose which ads you see, and never shared with advertisers. You can decline location entirely and choose one of Guam's villages instead; the app works fully either way, and the choice can be changed at any time in Settings.
When an ad is shown, tapped, or used to call, get directions to or visit a business, the app sends our server a record containing only:
The record contains no device identifier, no account, no session, no location and nothing else about you, and our database does not store IP addresses with it. Advertisers receive totals only — for example, how many times their ad was seen in a month — never individual records.
To work out "first time today", the app remembers on your device which ads it showed today. That list is one day deep: earlier days are discarded rather than kept, so it cannot build up into a history of what you have seen.
Ads and promoted events can offer to call a business, get directions to it, or open its website or ticket page. Those actions hand you over to your phone's dialler, its maps app (Apple Maps on iPhone, Google Maps on Android), or a web browser, and whatever happens next is between you and that business — and, for directions, the maps provider — under their own privacy practices. Guam Life only counts that the button was used, as described above.
Deleting the app removes all of this.
The magazine's articles and images, the events listings, the ads, and the anonymous advertising counts described above, and the push notification address described below. Nothing that identifies you. Our hosting provider, like any web host, may keep standard request logs, including IP addresses, for a short period for security and to keep the service running. We do not use those logs to identify or profile anyone.
If you allow notifications, weather alerts are worked out on your device from the weather data the app has fetched.
The one exception is the island's Condition of Readiness (COR). So that a COR change — and any official message sent with it — can reach you even when the app is closed, the app registers your device for push notifications when it starts. Apple (on iPhone) or Google's Firebase (on Android) gives the app a push address for this device — a random string that works only for sending notifications to this app on this device — and the app saves it to our backend along with:
Nothing else is attached: no name, no account, no location, no contact details. We use it only to tell every registered device at once when the COR changes — never to single anyone out, and never for marketing or ads. Whether a notification appears on your screen is governed by your notification permission; the address is registered either way, and is simply unused if you have notifications turned off. When Apple or Google reports an address as no longer valid — for instance after the app is deleted — it is removed the next time a notification is sent.
To answer a request, each service necessarily receives what is being asked about — for the weather services, the coordinates — and, as with any internet request, your device's IP address. Each has its own privacy practices, which we do not control.
| Service | Provides | Operated by |
|---|---|---|
| Supabase | Magazine, events, ads and ad counts; stores push addresses | Supabase Inc. (our backend host) |
| Apple Push Notification service (iPhone) Firebase Cloud Messaging (Android) | Delivers COR notifications | Apple Inc. Google LLC |
| api.weather.gov | Forecasts, observations, alerts | US National Weather Service |
| radar.weather.gov | Radar imagery | US National Weather Service |
| aviationweather.gov | METAR and TAF | US National Weather Service |
| tidesandcurrents.noaa.gov | Tide predictions | US NOAA |
| data.epa.gov | UV index forecast, asked for by island and not by your position | US EPA |
| earthquake.usgs.gov | Recent earthquakes near Guam, asked for by island and not by your position | US Geological Survey |
| data.jma.go.jp | Satellite imagery | Japan Meteorological Agency |
One of these — the Japan Meteorological Agency — is outside the United States, so requests to it leave US jurisdiction. We mention it because it is true, not because anything unusual happens to the data.
Guam Life sells nothing and has no purchases of its own. The magazine's ads come off when you subscribe to GL Weather, our separate paid weather app, on the same device. That subscription is sold in GL Weather and processed by Apple through the App Store on iPhone, or by Google through Google Play on Android. Guam Life never sees or handles your payment details and never asks the store about you: it reads only the note from GL Weather described above, saying whether that subscription is active.
Guam Life is not directed at children and collects no personal information from anyone, including children. The push address described above is not linked to any person.
If this policy changes in a way that affects what the app does with information, the updated date above will change and the new version will be published here before the change ships.
