QIP.Online - Is it safe?

Today, my QIP Infium offered to download the latest version of the client - QIP Infium RC3 (9017). After that, an offer to download the QIP.Online client also appeared, which reports on new incoming messages from:

Odnoklassniki.ru
Vkontakte.ru
My Mir@Mail.Ru
Vspomni.Ru
Loveplanet.ru
Mamba.ru (and all partner sites, including dating on Mail.ru and Rambler.ru)

Immediately the question - is it safe? And to be more precise, aren't the creators of QIP stealing my passwords? After all, on all social networks in the support service they say that in no case can you enter your logins and passwords except inside social. network. Or QIP'a agreement?
