Use nostr:npub1exv22uulqnmlluszc4yk92jhs2e5ajcs6mu3t00a6avzjcalj9csm7d828 messenger! It gives you the best #privacy protection.
Unlike #Signal it doesn’t need your phone number.
#Telegram and #WhatsApp not only want your phone number they collect loads of data and metadata from your device. Especially vile is the collection of your device‘s IMEI (device ID) and sharing all that data with companies to make money and with authorities due to the need to comply.
In authoritarian countries this metadata can cost you your life!

It is, but if an authority demands access to your data they’ll get it. And your metadata gives away a lot of information. When did you talk with whom, where etc.

Encrypted after side client scanning so encryption matter a lot in this case
