Being on vacation for a few weeks, I only have access to public WiFi.
After I have done some research on google and using the search button here (because "how safe is public WiFi" is a really common question), there's one question I have left: Since encryption seems to make my logins and my WhatsApp messages safe, I wondered if this is true for contacts too?
Is it possible that my number or the number of my phone contacts is exposed? I have disabled any app to have access to those except WhatsApp, phone, messages and Google services.
While the content of the messages may be encrypted - is the contact information like a phone number encrypted, too? Or is it more like that I am spreading the numbers of my friends and family through public WiFi, while no one can read the messages?
