Before using the service
Privacy, data and limitations
Data sent to external services
Place names submitted with Find are sent to the configured geocoding provider. Coordinates A and B may be sent by the server to Copernicus Data Space to retrieve elevation tiles. Map and satellite tile providers receive the usual web request information, including your IP address and browser headers.
Browser geolocation
Your position is requested only after you select “Use my current location” and grant browser permission. It is used to fill point A. Sightelo does not intentionally create user accounts or store a history of your calculations.
Local caches and operational logs
The server caches place-search responses and elevation tiles to reduce calls to public services. Operational logs may contain request paths, response status and duration, but are not designed to contain OAuth secrets. Hosting providers may retain IP addresses in their access logs.
Indicative result
The calculation models terrain, Earth’s curvature and optional standard refraction. It does not model buildings, vegetation, clouds, haze or local variations in atmospheric refraction. Do not use the result for navigation, rescue, aviation or any safety-critical decision.
