If privacy is of uttermost importance
This messaging app does not require phone number. Can register with whatever lexis or in language you wish.
In order to find somebody, one needs an invitation, either a link or a QR code and confirming a profile - incognito or regular one.
So, no spam, ads, strangers won't reach you.
Multi layer encryption, quantum resistant too.
Proxies change, the app is rather DEX like. All data on a mobile device until servers deliver chunks of cryptic info.
6.2 or 6.3 beta has gotten Flux crypto security.
They've got the policy of honesty - if asked for data by officials tney publish it. None of that has occured yet.
Read what you accept. A lot of interesting things can be found out.
Chat groups are also present.
The app is free of charge by now
