What this site does
Open Bolt is a free map tool. You choose a location and time range; the site sends that search to our API, which reads public NOAA GOES-R GLM data. There are no user accounts and no paid features.
Data we process
- Search parameters — latitude, longitude, date, and time range you enter are sent to our backend API to run the query.
- Browser location — if you tap My location or use map geolocation, your browser may ask permission; coordinates are used only in your browser session for the search form.
-
Theme preference — light/dark mode may be stored in your browser’s
localStorage. - Analytics — aggregate page views and usage via Google Analytics (GA4). Google may process IP address, device and browser information, and pages visited. See Google’s privacy policy.
What we do not do
- No selling or sharing of personal data
- No login or email collection
