When you say simplex collects users data, What do you mean? If I self host it and people use my server, that those people's Data is on my server? But if they use the anon feature, you're saying Metadata right? If that's what you're saying I'll go check my logs and see what exactly I can view and see if I can setup a purge job.

well that's weird: when I said simplex collects users' data, I meant «when you use application SimpleXChat, it sends anonymized diagnostics about the use to improve your usage experience» — yet now I cannot find any proofs of that not. I was sure I read it myself in their privacy policy. Huh...
Anyway, yes, official servers do collect some statistics (which may be somewhat dangerous: https://www.nature.com/articles/s41467-019-10933-3 — yet not too bad). I'm not sure if using own server won't identify you by centralizing all your connections, killing the main reason to use the app: when 100 (your) pseudonyms uses all one same small server, and no or almost no other people are using it, pseudonyms can clearly be identified as belonging to a one person, or am I wrong?
You'd have to have a link between the pseudonym and the user right? So that only exists upon full server compromise right? I which case only the admin would be fucked (potentially) VS users bc you'd assume those using simplex would use a vpn giving them plausible deniability between and user IP correlations
