Re: Contacts
You said that you'd allowed WhatsApp access to your contacts.
WhatsApp is owned by FaecesBorg and had steadily changed it's T&Cs to the detriment of anyone but FaecesBorg. It's proven that you cannot trust any statement by FB regarding privacy - after all, it's most senior person has no problem lying to the US government about what it does !
So by allowing WA access to your contacts, you have broken the law - simply because you cannot have any confidence in that information remaining confidential. That's the case even if not a single piece of information did end up with FB - which I would doubt anyway.
Unless, for every single contact, you got their informed consent to allow their details to be given to WA.
EDIT: Oh yes, whether or not you think you have a FB account is largely irrelevant. Max Shrems demonstrated that you have an account with them whether you like it or not - that was in a large part the substance of his original complaint, that they were building shadow profiles of people without the consent of the data subjects.
