provided you have whatsapp and facebook on your phone the following happens though. 1. they both know your mobile phone book. 2. they both know your imei 3. they both know your phone number(this doesn't have to be the same by the time you sign up for the other) just no.1 is already enough to get an accurate estimate on who the person is. notice how they never said that they didn't log that information? it's also very unlikely that they don't have access logs to their service, which usually includes ip's i.e. location, but for all we know they could be encoding carrier information in a couple of bytes during the transmission of the contact list. edit: while the mobile ip's don't give you exact information, they still give you enough heuristics to overlap them with other services

> it's also very unlikely that they don't have access logs to their service, which usually includes ip's i.e. location. In mobile data world, the norm is MASSIVE NAT. Thousands of users per IP (you can IIRC make 65535 distinct connections over a single NATd IP). Also, the connections are usually terminated in one (or fairly few) data centres, so the IP only tells you the country and the provider, nothing more.

If I had known for even a second that the reason whatsapp took so long to start up on my phone, was it uploading MY ENTIRE PHONEBOOK to their servers, I would never use it. The damage has been done, but I never will use it. I don't understand how the whatsapp CEO can come out with a statement like this while presiding over a program that behaves like this.

Not only that but a few days ago they updated the Android app which can now retrieve your running apps. This means that, given enough time, they know all the apps you have installed. They also force you to update to the new version. Failing to do so means you can no longer use the app. They turned evil and that's why me and my friends started using Telegram. They don't care but privacy, they care about money, let's cut the BS.
