MeshCore Coverage Mapper — Last updated: April 2026

Overview

MeshCore Coverage Mapper is an Android app that connects to MeshCore LoRa mesh devices via Bluetooth Low Energy (BLE) to record signal coverage data. This coverage data is used to build a community coverage map at mapme.sh.

This policy explains what data the app collects, how it is used, and what choices you have.

Data We Collect

Data Type	Details	Purpose
GPS Location	Your device's GPS coordinates, converted to H3 hexagonal grid cells (~150m resolution)	Map where you recorded signal coverage
Signal Samples	RSSI (signal strength) and SNR (signal-to-noise ratio) from received LoRa packets	Measure and display network coverage quality
MeshCore Device Info	Your MeshCore device's public key and node name	Session verification and leaderboard display

The app does not collect:

Personal information (names, email addresses, phone numbers)
Advertising identifiers or device fingerprints
Contacts, photos, or other files on your device

How We Use Your Data

All collected data serves a single purpose: building and displaying a community coverage map for the MeshCore LoRa mesh network. Coverage data is aggregated into anonymous hexagonal grid cells and shown on the public map at mapme.sh.

Privacy Modes

The app gives you full control over your data sharing through three privacy modes:

Live: Your position is visible on the map in real-time. Coverage data appears immediately.
Ghost: You are not visible on the map. Coverage data is submitted anonymously and appears after a 24-hour delay.
Offline: No data is uploaded to the server. Nothing leaves your device.

Data Sharing

We do not share your data with third parties. Specifically:

No data is sold to advertisers or data brokers
No advertising or analytics SDKs are included in the app
No tracking frameworks are used
Coverage data is only transmitted to mapme.sh servers

Data Retention

Data Type	Retention
Coverage hexes (signal data)	Stored indefinitely as anonymous, aggregated data
Leaderboard entries	Until you request deletion
Live mapper status	Removed shortly after your last activity
Session tokens	24 hours

Permissions

The app requests the following Android permissions:

Location (Fine/Coarse): Required to record GPS coordinates for coverage mapping
Bluetooth: Required to connect to MeshCore LoRa devices via BLE
Internet: Required to upload coverage data to mapme.sh servers

Data Security

All data is transmitted over HTTPS (TLS encryption)
Session authentication uses cryptographic signature verification
No passwords are stored
Server infrastructure is hosted in Germany by Hetzner Online GmbH

Your Rights

You can:

Use Offline mode at any time to stop all data collection
Use Ghost mode for anonymous, delayed contributions
Request a copy of your data by contacting us
Request deletion of your data by contacting us
Uninstall the app at any time to stop all data collection permanently

Under the GDPR, you also have the right to access (Art. 15), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), and objection (Art. 21). You may lodge a complaint with a data protection supervisory authority.
