How This Data Is Sourced

Timezone

Read directly from your device's operating system using the Intl.DateTimeFormat API. No network request needed — it is always available instantly.

Elevation

Looked up from a global digital terrain model (SRTM/Open-Elevation) using your GPS coordinates. Accuracy varies from ±1 m to ±30 m depending on terrain.

Nearest City

Resolved via reverse geocoding against OpenStreetMap data (Nominatim). Returns the city, town, or village name associated with your coordinates.

Postal Code

Extracted from the same reverse-geocode result or, when GPS is unavailable, estimated from your IP address via ipinfo.io.

Frequently Asked Questions

Elevation is looked up from a digital terrain model based on your GPS coordinates once you grant location permission, rather than measured directly by your device.

Your timezone is read from your device's operating system settings, which is normally accurate, but it identifies a representative city for the whole timezone region rather than your specific location.
