The Privacy-First, Open-Source Life360 Alternative for Android.
🌟 Why Kin-Tracker • 📊 Comparison • 🚀 Features • 🛠️ Tech Stack • 🌟 Ecosystem

- 🛡️ 100% Privacy-First: No location data brokers, no user telemetry, and no accounts required — data is encrypted and shared strictly within your private family circle.
- ⚡ Bulletproof Screen-Off Background GPS: Intelligent hardware
WakeLockcycling and foreground service prioritization ensure continuous 24/7 location streaming without being killed by Android Doze mode. - 💸 Free & Sovereign Forever: No paywalled geofences, no driving reports subscription fees, and zero ads.
