Man, if you really value your privacy you shouldn't use WhatsApp (difficult of course as everyone uses it)
and social media (difficult as everyone use it), except for Lemmy, Mastodon or Signal !!
Privacy is not an easy path as it's against the whole mainstream society.
But its worth embracing, because it's a human right, even if it's not "comfortable" doing so.
Edit: there is of course other ways of communication like regular phone calls or sending SMS instead of WhatsApp messages. So feel free to liberate yourself.
