I treat WhatsApp as a hostile app[1], which means I deny any access to my stuff even if I get a subpar experience. In places where it's required (as where I live), this is the bare minimum a privacy-minded person can do.

Yeah but other people share their contact list with WhatsApp and they have you in there, with your name and phone number and possibly more info.

I never understood why Apple allows access to the full address book including all Apple-specific settings such as "spouse" and "home address" that are useful within iOS. There should be a minimal permission mode: name and phone number only.
