Looking for a CLI-friendly pastebin service for with decent privacy policy, open source, and has at least shortest retention of 1 month. Other features in order of priority:

• free (self-hosting inevitably means it's not free when you need to pay to host?). Obviously this would be the best option in terms of privacy.

• does not require dedicated client (except a simple shell script) or much additional dependencies if at all.

• shorter burn retention, e.g. 1 day, 1-2 weeks. Ideally, burn on-demand!

• Optional syntax highlighting.

• optional encryption. Raw text needs to be supported because most people use a pastebin service to share to stuff to the public.

Arch Wiki is the first place to check, but the here is what I've found after some brief searching of popular services:

• ix.io: "The codebase for ix.io is intended to be free and open-source. It is not published at the moment..." (not likely to ever be published tbh, ix.io has been around for a long time).

• sprunge: No response from author regarding retention.

• 0x0: No real predictable/controllable way to delete pastes (you need to message the author to delete...). Smaller pastes retain for ~365 days.

• termbin: As I learned today after setting up a shell function last night, it relies on port 9999(? Which seems like it's blocked at Dunkin' Donuts... or at least I get the error: ztcp:16: connection failed: connection timed out that I didn't at home.

At the end of the day, you're posting unencrypted raw text online, so you should assume everything posted is on the internet forever. But there are so many pastebin services available and it's a popular tool used by IRC (open protocol that encourages decentralization) so it's hard to imagine there isn't one that is particularly privacy-friendly for raw texts (PrivateBin seems promising but it requires encryption).
