In addition to that, in most European countries you have to register with your ID in oder to get a mobile phone number. So its provably end-to-end related to your identity.

I prefer apps that require no phone number. Like Threema, SimpleX, Session, Status, XMPP, or Tox.

SimpleX is good tho.

How does signal match your contacts based on their phone number then?

Hashing doesn't really do anything because there are too few possible phone numbers. Easy to bruteforce. See the researchers who enumerated the WhatsApp users database recently via the internet...

Is it good?

I have had this idea in my mind of building a privacy-first, open source dating app built on "privacy by design" principles. Still didn't get to it tho.

Tried it, doesn't work. Too many bugs. I can't input a location and it fails to auto-detect so I am just living in cyberspace apparently.

Depends on your security and feature requirements. I found that Mega works well for music streaming on mobile, and the E2EE is reasonably trustworthy for that use case.

Did someone call me?

No.

Fortunately VPN exists in Italy, too.

First you should ask yourself why you would not want advice.

Which results in: a) accept and implement advice OR b) prove the advice wrong
