Geofencing
A geofence may trigger a message, workflow, measurement event, or access rule. Implementations rely on location services and must account for accuracy, battery use, background permissions, and delayed signals. Because location can be sensitive, teams should use clear purpose limitation, appropriate consent or other legal basis, minimal precision, and conservative retention.
What is Geofencing?
Geofencing uses a virtual geographic boundary to detect when a device enters, exits, or remains within a defined area.
Why it matters
A geofence may trigger a message, workflow, measurement event, or access rule. Implementations rely on location services and must account for accuracy, battery use, background permissions, and delayed signals. Because location can be sensitive, teams should use clear purpose limitation, appropriate consent or other legal basis, minimal precision, and conservative retention.
Example
A transit app sends a service alert when an opted-in user enters a station area affected by a closure.
