There is also Chitchatter, an encrypted P2P communication platform, ephimere, no account, similar Otr
Also SimpleX although your server probably needs to run in Linux not Android.
P2P don’t need really an server or selfhosting, content’s are pointing direct to the user devices. The drawback is that your device must be online when the receptor want to retrieve the content. There is nothing which store the content in between. The advantage, more privacy impossible, out of the reach of any third parties, not even the ISP.
There is also something similar, like eg. Croc, which allows even the transfer of any content this way, full encrypted like the others, same as the others is download and use it.
P2P is always the safest form to communicate and share content, as it was since the beginning with the paleolytic finger command from 1971, which still can be used for text transfer (most Linux, Unix like Mac and Windows)
Eg, write in your command line

Finger is a security risk.
Naturally, because it isn’t encrypted, not so good for sharing sensible information, that is the only risk. Despite that you see my message in your console, it isn’t possible for me to access through this to your PC, nor that you can access to my data with it, apart of the sended text, which can see anybody with the finger link. But it’s a curiosity and the ancestor of the P2P, nice to prank your friends and for fans of vintage computing, because it’s way older as the internet we know. Apart it’s so old, that it isn’t anymore in the focus of govs and hackers, it’s like sending messages with Morse or with an FAX.
