Privacy policy
Last updated 9 November 2026
BaroCast (“the site”) is a free tool that shows barometric pressure and weather for places around the world. This page explains what information is used when you visit the site, who it is shared with, and the choices you have.
Information we collect
The site has no accounts and we do not collect your name, email address or other personal details. We do not run our own analytics or tracking.
Stored on your device only. Your settings (units, theme), favourite and recent places, report details you type in (such as a site name or notes) and cached weather data are saved in your browser’s local storage and IndexedDB. This information stays on your device and is never sent to us. You can remove it at any time by clearing this site’s data in your browser settings.
Your location
If you choose Use my location, your browser asks for permission and then gives the site your approximate coordinates. They are used only to fetch weather and a place name for that spot, as described below. We do not store or receive your location.
Services the site uses
To work, the site’s pages in your browser connect directly to these services, which receive your IP address and the details of each request:
- Open-Meteo (weather data and place search): the coordinates, dates or search text needed for each request. Terms and privacy.
- BigDataCloud (place names for “Use my location”): your coordinates. Privacy policy.
- Esri (map tiles): the map area being viewed. Privacy statement.
- GitHub Pages (hosting): standard web server logs. GitHub privacy statement.
