Privacy
Last updated: August 2026
The short version
This app needs no account, no email and no personal data. You pick a point on a map; we compute physics for that point.
Your location
Coordinates you select (or share via your browser's geolocation, only after you tap the button) are sent to our server solely to compute solar results and fetch irradiation data. They are never stored together with any identifier. Cached solar data is keyed to a ~5 km grid cell, not to you.
On-device storage
Your language choice and last viewed location are kept in your browser's local storage so the app remembers them. They never leave your device.
Third-party services
Solar data is fetched from PVGIS (European Commission) and NASA POWER; place search uses OpenStreetMap Nominatim; map tiles are loaded from their providers. These requests are proxied or covered by the providers' own policies.
