How secure is sending files over Bluetooth? (lemmy.ml)

If I pair my Android phone and my laptop, I can share files over Bluetooth from the phone to the laptop. I've started finding this a really convenient method for me to send files to a Linux laptop without needing to install a separate app on either the phone or my laptop. Especially when I'm away from my home network (I use SFTP at home).

How secure is this? Is there encryption by default and could someone else nearby with a receiver potentially decode the file you're sending?

If it passes through, that means it is present on the server's storage, even if for a short period of time

All your data and traffic passes through various routers and servers (both of which are computers and have memory) while you do anything on the internet (You can find the list of such computers by doing a traceroute). But because it is end to end encrypted - you don't care.
