How secure is the transfer in syncthing?

I’m sorry as I don’t quite get it. Not a tech savy person. I read somewhere that syncthing transfers the files as is from one to another.

I read in the documentation that the file on transfer is protected by TLS Encryption.

My question is, can the relays or the global discovery see my files being transferred? I mean, the files are being passed from thru those relays right? Meaning the files touch those servers/relay, or am I wrong here? should cover all your questions (especially the sections on global discovery and relaying). If anything isn’t clear, please point them out.

Just for clarity, no, the Syncthing infrastructure can’t see or touch your files.

Okay, I quite get it know. Thank you very much.
