Selfhosted @lemmy.world Using Termux to create a tiny selfhosted hidden chat server with E2EE.

Yes it can. I've been doing it for the past few months. You can also host onion services really easily with no root needed.
Here is a clone of Instagram I made for termux. It's all inclusive and will turn your phone into a social media web server.
I've been testing this with 6 family members over the past 3 weeks it works really well for what it is. We have over 100 private posts. Just follow the usage instructions and you can turn your phone into a little private social media safe haven.
