(1) The policy differs per country. But how is it different in practice between the EU and USA and Brasil? It's not public knowledge.
(2) It's absurd the policy doesn't describe anything useful. I tried to find if the contact book is being sent to facebook and if so, for how long. The wording is so opaque it's impossible to figure out.

> When WhatsApp launched a major update to its privacy policy in August 2016, it started sharing user information and metadata with Facebook. At that time, the messaging service offered its billion existing users 30 days to opt out of at least some of the sharing. If you chose to opt out at the time, WhatsApp will continue to honor that choice. The feature is long gone from the app settings, but you can check whether you're opted out through the “Request account info” function in Settings.

That's good news but I can't find this stated anywhere in their policy:

It seems like an important thing to mention.
