Overview

Mapme.sh is a coverage mapping platform for the MeshCore LoRa mesh network. This policy explains what data we collect, how we use it, and what rights you have.

Hosting

This website is hosted on a server operated by Hetzner Online GmbH in Germany. All data processing takes place in Germany.

Data We Collect

1. Location Data

What: Your GPS location, converted to H3 hexagonal grid cells (approximately 150m resolution)
Why: To record where you mapped and show coverage on the map
Storage: Coverage data is stored indefinitely as aggregated, anonymous hexagons

2. Radio Signal Data

What: Signal strength (RSSI) and quality (SNR) of received radio packets
Why: To show network coverage quality on the map
Storage: Stored indefinitely, associated with location hexes only

3. Device Information

What: Your MeshCore device's public key and node name
Why: To verify your session and display your name on the leaderboard
Storage: Stored for leaderboard functionality

4. Live Mapper Status (Live Mode only)

What: Your current location and online status
Why: To show active mappers on the map in real-time
Storage: No longer displayed shortly after your last activity

5. Server Logs

What: When using the platform, technical access data may be recorded server-side (e.g., IP address, timestamp, accessed endpoint)
Why: To ensure platform operation and prevent abuse
Legal basis: Legitimate interest (Art. 6(1)(f) GDPR)

Privacy Modes

You control your visibility with three modes:

Live: Your position is visible on the map, data appears immediately
Normal: Not visible on map, coverage data appears after 3 hours
Ghost: Completely anonymous, data appears after 24 hours

Data Anonymity

Coverage data (colored hexagons on the map) is anonymous — it shows signal quality in an area, not who measured it
Only in Live mode can other users see your approximate position
The leaderboard shows node names and points, but not location history

Data Retention

Data Type	Retention Period
Coverage hexes (signal data)	Indefinitely
Leaderboard entries	Until deletion requested
Live mapper status	A few minutes after last activity
Session tokens	24 hours

Cookies and Local Storage

Mapme.sh does not use cookies. However, the following client-side storage technologies are used:

localStorage: Map preferences (e.g., selected map style), cached statistics
sessionStorage: Welcome dialog control (shown once per browser session)

This data does not leave your browser and is not transmitted to our server.

Access (Art. 15): Request a copy of your data
