Introduction

Colota is a self-hosted GPS tracking app for Android. It sends your location to your own server over HTTP(S), works offline, supports geofencing, and doesn't share any data except with your configured backends.

Key Features

Self-Hosted - Send location data to your own server via REST API. Works with Dawarich, OwnTracks, PhoneTrack, Reitti, Traccar, or any custom backend.
Privacy First - No analytics, no telemetry, no third-party SDKs, no cloud services. Open source under AGPL-3.0.
Works Offline - Works without a server. Store location history locally and export as CSV, GeoJSON, GPX, or KML.
Background Tracking - Foreground service, auto-start on boot, retry with exponential backoff, battery-critical shutdown.
Geofencing - Create pause zones where location recording automatically stops.
Tracking Profiles - Automatically switch GPS interval, distance filter, and sync settings based on conditions like charging, car mode, or speed thresholds.
Sync Modes - Instant, batch, or offline. Wi-Fi only sync, configurable intervals with automatic retry.
Data Export - Export location history in CSV, GeoJSON, GPX, or KML formats.
Authentication - Basic Auth, Bearer Token, or custom HTTP headers with AES-256-GCM encrypted storage.
Quick Setup - Configure devices instantly via colota://setup deep links or QR codes. No manual typing required.
Dark Mode - Full light and dark theme support.
