Reticulum packets include a hop count of how many nodes it’s been through (to prevent packets looping indefinitely) and the destination address. Two way links use tables on each node to reverse the route back to the origin and don’t use origin addresses.

The worst part privacy wise could be the announce packets which include a hop count and the address for the origin so if you had enough interfaces you could roughly say where a node is on a network graph (geo locating that is an entire other problem)

Privacy also depends on what interfaces you communicate over, eg TCP reveals IP addresses to the nodes you directly connect to (combine with hop counts to see if a packet definitely originated from that node), LoRa gives an idea of how close it might be because of its range limits and the fact radio emissions can be located.
