Does this send my files remotely?

I just installed Syncthing on Linux and when I launch it in the command line, I notice various worry external IP addresses and wonder what they may be for?

I simply want to syncronize a local desktop with a local laptop and don’t see any reason to be connecting to anything outside of my local network.

The specific references are:

[DPIPJ] 19:39:23 INFO: Relay listener (dynamic+https://relays.syncthing.net/endpoint) starting

[DPIPJ] 19:39:23 INFO: Using discovery mechanism: global discovery server https://discovery-v6.syncthing.net/v2/?nolookup&id=LYXKCHX-VI3NYZR-ALCJBHF-WMZYSPK-QG6QJA3-MPFYMSO-U56GTUK-NA2MIAW

[DPIPJ] 19:39:33 INFO: New NAT port mapping: external TCP address 100.86.109.91:2795 to local address 0.0.0.0:22000.

[DPIPJ] 19:39:43 INFO: quic://0.0.0.0:22000 resolved external address quic://112.204.160.63:22447 (via stun.syncthing.net:3478)

[DPIPJ] 19:40:57 INFO: Joined relay relay://139.162.117.43:22067

Is anyone able to put my mind at rest regarding these please?

Please check https://docs.syncthing.net/users/security.html.

You can disable relaying and global discovery, as well as NAT punching in the Settings > Connections panel. If you ever need more than local LAN sync, don’t forget to turn them back on.
