It is proven! I am apiote on Keybase: https://keybase.io/apiote/sigchain#fb83a3b2df36ba0bef2627e3ae5b2214fa90533317f005a038f3d3e84f621ff20f
I have ditched the #protonmail Android app. It was the last non-FOSS one on my phone. It complained all times about Google Services I don't have (LineageOS). And now I discovered that the said app uploads all the contacts I mail to PM’s servers where they’re kept in an unencrypted form. Not to mention all the bugs—since 2 versions or so the app crashes when there's no Internet connection. And new versions introduce only regressions; no changelog, no new functions. Just misery.
The PM client can authenticate with single password so it now has a name (Cobalt) and a repo (https://notabug.org/apiote/Cobalt)
I’ve put off tooting this but now that my room is painted (and I didn’t paint it, black) I think I shouldn’t any more.
I hereby claim to be the man behind @bimba. I also code Miei (E2EE, self hosted, free as in freedom contacts and calendars storage) [https://notabug.org/apiote/Miei-server], and as of lately I try to write an Android client for ProtonMail.
