FritzTrack4U is a local, LAN-only tool. It talks to your FritzBoxes over TR-064 on your home network and (optionally) to a local MQTT broker. It makes no outbound internet connections and uses no cloud service or API keys.

• Credentials live in config.json (FritzBox users + MQTT) in plain text. This file is excluded via .gitignore — never commit it. Restrict its permissions: chmod 600 config.json.
• Create a dedicated FritzBox user for FritzTrack4U with only the "FRITZ!Box settings" permission, and do not allow internet access for that user. Don't reuse your admin password.
• The SQLite history (*.db) contains movement data of the people you track. Treat it as personal data. The 60-day auto-cleanup limits retention; lower retention_days if you want less.
• Data protection: use this only in your own home, for people who consent (your household). Tracking employees or customers raises serious GDPR/privacy issues and is explicitly not the purpose of this project.
