I will make things clearer. #HolosSocial has no web version. It can display profiles with some messages (during the TTL for public messages). The server runs on your device, and https://holos.social is just a relay that remains account-agnostic, so your account has little dependency on it.
This is very important to understand before using Holos Social. It is very different from what you currently use on the #Fediverse.
