DeletedUser218 I'm still concerned... Is WhatsApp spying on me?
If you deeply care about privacy, do not use Whatsapp. It's owned by Meta/Facebook and is not open source, so nobody can verify which privacy violations it may or may not do.
You can choose to use Signal/Molly, Threema, SimpleX and others. But of course you will have to convince those who you really want to comminicate with to use that app too.
