Your privacy

Your location

Location is only used when you press “Use my location”, and only after your browser asks you. Your coordinates are sent to LA County’s and CalHeatScore’s public map services to work out your city, community or ZIP code, and are used to sort relief sites by distance. HeatGridLA does not send them anywhere else and does not save them: they are gone when you close or reload the page.

What is kept on your device

The site uses your browser’s local storage, not cookies, for:

• the area you last chose (a ZIP code or city name), so your local emergency numbers are ready next time;
• your language choice (English or Spanish);
• short-lived copies of public data (heat scores, fire zones, forecasts and open relief sites), so pages load faster.

Nothing in local storage is sent to HeatGridLA. To remove the saved area, press the × next to it under Emergency contacts; to remove everything, clear this site’s data in your browser settings.

Services your browser contacts

To show live, official information, your browser loads data directly from these public services. Like any website, they receive your IP address and browser details when it does.

• OpenStreetMap — map tiles (the background map).
• CalEPA CalHeatScore and CAL FIRE (hosted on Esri ArcGIS Online) — today's heat scores by ZIP and the fire hazard zones.
• LA County and City of Los Angeles map services (LA County GIS and ArcGIS Online) — relief sites opened for a current heat event or emergency, and which city or community a point is in.
• National Weather Service (api.weather.gov) — the forecast high for the area you are looking at.

“Google Maps” buttons open Google Maps, which has its own privacy policy.

Hosting

The site is hosted by Lovable. Its servers receive standard request details (such as your IP address and the page you asked for) when pages load. If a page crashes, a description of the error and the page address may be sent to Lovable so it can be fixed.
