My VPS (virtual private server) is hosted on Soleus hardware, which is managed by the community of techie members. My website is here, plus my own chat instance using the Matrix protocol (Synapse implementation) and Jitsi videoconference software.
I fully support Delta Chat messaging. Download it asap, because it really is the most private app there is. Unlike the others (Signal, Telegram, etc) it doesn't need to know your telephone number. Feel free to contact me, I am happy to help you get acquainted with it.
