Open-Mesh tracks only the computer MAC address (and the computer name if given in the DHCP leases file). Usage tracking is only aggregate bytes up and down. We do not track, store, save or in anyway know about anything else, and even the above aggregate data is only tracked and saved for 24 hours.
On open reports (when no password is given), we mask significant parts of the MAC address and do NOT show the computer name. To see this info, you must be the network administrator or have that password.
