BEHIND THE APP
WHAT KEEPS SENSORCIRCLE RUNNING?
Every search you make is backed by our servers that pull offender information from the national registry every single night — geocoding hundreds of thousands of addresses and delivering results to your map in seconds. That infrastructure has real costs.
SensorCircle was built and is maintained by a single developer who believes this information should be free and accessible to every family —not locked behind a subscription. If the app has been useful to you, a contribution of any amount helps keep it that way.

Dedicated hosting running 24/7 to serve every search instantly.
NIGHTLY DATA PIPELINE
Automated processes that run every night refreshing 500K+ offender records.
GEOCODING
Converting addresses to precise map coordinates for every offender location.
ONGOING DEVELOPMENT
Keeping the app current with every iOS and Android platform update.
