Your coordinates are checked against live lightning-strike networks, official national weather service warnings (Met Éireann in Ireland, the Bureau of Meteorology in Australia, MetService in New Zealand) and thunderstorm forecast models. When a storm is heading your way, we send a push notification to your device using the stored token — a Storm heads-up when strikes are detected or imminent, and a Thundery watch earlier in the day when the forecast shows a risk.
We share your coordinates with those weather and lightning data providers only to calculate your alerts. They receive a map position, never your identity. Your data is never sold, never used for advertising, and never used to build a profile of you.
