Privacy hardening Grafana / Prometheus ? (ttrpg.network)

I have enough machines on my network that I've long wanted to get better monitoring going on, and I finally bit the bullet and I'm trying to push through learning my way around grafana and prometheus/node extension. I have been following this guide: https://grafana.com/docs/grafana-cloud/monitor-infrastructure/metrics/metrics-prometheus/prometheus-config-examples/docker-compose-linux/ (great, btw!) but after importing the dashboards so I have three dashboards providing some intense readouts of three different machines, it got me wondering: how privacy protective is this? Is Prometheus just sending out a steady stream of diagnostic data for anyone to snoop on if they get access to my LAN? How can I/should I harden these setups to be privacy conscious?

Since you don't need access to prometheus you could limit it to be only accessible by grafana and the servers you are pulling from. Other than that, you should read this https://prometheus.io/docs/operating/security/
