Obviously it comes to personal judgment when people use my tools. I mean they could also do as described in transfer.sh, pipe first the data through gpg. The server accepts any kind of data as long as it doesn't overflow the current set size limit.

But indeed I do agree that I can't guarantee or even prove that I can't access the files on my server. That's why I offer a quick and simple way for people to setup this on their own machine, so they can have this lightweight server and use it as if it was mine just by modifying a line in the configuration file of the client (or changing the URL in the curl commands)

I'm glad you enjoyed the tool though :D
