We don't collect your data
We do not store your searches, locations, AI requests, IP-based profiles, or any personal information on our servers. The only thing counted is anonymous page views, described below. AI requests are processed to generate a response and are not retained.
Anonymous visit counts
We count visits with Vercel Web Analytics, which is part of the service that hosts this site. It sets no cookies and stores nothing on your device. For each page view it records the page address, the site that linked you here, an approximate location (country, region and city) worked out from the request, and your browser, operating system and type of device. Anything after a ? or # in the address is removed before the count is sent, because that part can hold a place you searched for. It does not store your IP address. Visitors are told apart only by a hash of the request that Vercel discards after 24 hours, so a page view cannot be tied to you, to your other visits, or to what you do on other websites. What we see is totals: how many people opened which page. On this plan Vercel shows the figures for a month and may keep them longer, and we copy the daily total for each app into a private dashboard. Neither describes any individual. We count visits because knowing whether an app is used is in our legitimate interest, and the count is built so that it cannot identify you. A content blocker, or turning JavaScript off, stops the count and changes nothing else about the site.
What stays on your device
Your favorites, recent locations, and unit preference are saved only in your browser’s local storage — on your device, never sent to us. Clearing your browser data removes them. In incognito mode they vanish when you close the window.
Third-party data sources
Weather and hazard data come from public providers (Open-Meteo, USGS, GDACS, NASA FIRMS). Searching for a place calls Open-Meteo’s geocoder directly from your browser. When you load the map, tiles are fetched from OpenStreetMap / Esri, and the rainfall overlay from RainViewer. These providers may log standard request metadata under their own policies; we pass them only the coordinates needed to answer your query.
AI
AI features summarize only the verified data shown on the page and cite their sources. The AI never invents weather, severity, or coordinates.
