Find your house, then nudge the pin until it sits right on it. Overhead shows what's flying over that spot.
Drag the pin, or tap the map, to move it.
Your location, settings and flyover history are saved only in this browser. The server doesn't store them, and your location goes to it only inside each request, never in a web address. Address search goes to OpenStreetMap's Nominatim, and the ground elevation lookup to Open-Meteo, from your browser.
