QuicLoc

QuicLoc is an Android utility that lets trusted contacts request your real-time GPS location by sending a single keyword — via SMS or any messaging app. It responds automatically, even when your screen is off.

How It Works

1. You add a contact's phone number or display name to an encrypted, biometric-protected whitelist. 2. That contact sends you the message loc or quicloc (case-insensitive) from any messaging app. 3. QuicLoc detects the trigger, fetches your current GPS location, and replies automatically with a Google Maps link.

No app needs to be open. No buttons need to be pressed.

Features

- Homescreen Widget — Tap the widget once to mark your parking spot (texts your own number #Parking), double tap to alert up to 3 priority starred contacts (#SafetyCheck), or triple tap to alert your entire whitelist (#Emergency). - Works across messaging apps — responds to SMS, WhatsApp, Telegram, Signal, Google Messages, Messenger, and any app that supports notification inline replies. - Encrypted whitelist & Priority Contacts — trusted contacts, "My Phone Number", and up to 3 "starred" priority contacts are stored using AES-256-GCM encryption backed by the Android Keystore. The data never leaves your device. - Biometric protection — the app requires fingerprint, face unlock, or device PIN to open. Falls back to PIN/pattern if no biometric is enrolled. - Reliable location — uses a three-stage fallback (GPS fix → cached location → forced update) to ensure a location is returned even from a cold start. - Fully background — operates silently when the screen is off. Auto-replies work without the app being open or unlocked. - Passphrase & Device Lock — Set a 10-150 character single-use passphrase and a 6-digit PIN. Sending the passphrase starts a 5-minute location tracking interval and forces a lock screen on the device. Failing the PIN 3 times captures a photo of the intruder and escalates tracking to 1-minute intervals with MMS image updates. - No data collection — no analytics, no crash reporters, no servers. Nothing leaves your device except the location reply sent directly to the requesting contact.
