Learn how Telegram's bilateral Live Location system allows mutual participants to trigger automatic proximity alerts anywhere from 1 meter to 99 miles away, tracking dynamic compass orientation while conserving mobile battery.

Watch official Telegram Tips #117: Set up proximity notifications when sharing Live Locations in Telegram chats.
Static location pins tell you where someone was in the past; Telegram Live Location streams where they are moving in real time. When two friends or family members both share their live location inside a chat, Telegram turns the chat map into a collaborative tactical radar.
Rather than staring at the map continuously while waiting for a friend to arrive at a train station or café, you can activate a Proximity Alert. By tapping the radar bell icon, you define an invisible geofence perimeter (e.g., 500 meters or 2 miles). The moment your friend crosses that boundary, your device rings with a customized high-priority audio-haptic chime.

Telegram calculates device gyroscopic orientation and compass heading. The user's marker displays a pointed arrow showing which direction they are walking or driving.

Adaptive Polling Economy
When your device is stationary, Telegram throttles GPS sensor polling to conserve battery. When high movement velocity is detected, polling frequency adapts automatically.

Group Telemetry Maps
In group chats with multiple members sharing locations, all participants are rendered on a shared interactive map simultaneously with real-time distance readouts.
Continuous location sharing requires absolute privacy safeguards. Telegram builds four key layers of security into the Live Location feature:
Granular Ephemeral Lifespans: Choose to share your location for 15 Minutes, 1 Hour, or 8 Hours. Once the countdown expires, your coordinates cease broadcasting immediately.
Global Top Alert Bar: While live location is active, Telegram renders a prominent persistent banner at the top of your chat list indicating active location broadcasting.
Instant Red Button Revocation: You can terminate all active live location sessions globally across all chats with a single tap.
