No, they don't and it isn't. Well, maybe now they do, after I inadvertently stumbled into this. Apparently none of my existing contacts use Whatsapp, so thats why I see "No contacts yet. Try to resync". I wanted to try out this app after all the hype around here to see if I can suggest it to some close friends as SMS or IM substitute. I expected to be able to add those friends manually.

OK, I misunderstood the underlying technology and I know Wazapp is simply relying on the Whatsapp platform. But that's not the point.

What I don't understand is what you all get up in a huffy about someone asking for proper disclosure. I'm not saying the app shouldn't do what it does. I'm not trying to piss on your parade. All I'm saying is, include a dialog that says
"Running this app will upload your phone book to Whatsapp servers. Tap to agree."
Not something buried in 10 pages of "Terms & Conditions" legalese.

Is that too much to ask? Would it make the app any less useful for you guys? You are basically arguing "No, we MUST do this sneakily under the hood, without telling the user. We will absolutely not be upfront about it."
Why?

Maybe it would give some people pause and lead them to not sign up. But this is a 3rd-party app - tgalal, why do you care? You're not making any money from people using or not using the Whatsapp platform via your app. So what if a few drop out?

I actually did some digging and found Path did a similar thing not too long ago and they ended up apologizing profusely:

That story actually caused quite a bit of uproar and a lot of other companies got caught up in it and changed their policies:

Finally, even Apple now requires apps to get explicit permission before accessing contact data:

Say what you want about Apple and the iPhone, but in this case, why not follow that example?
