If you originate a telephone call or send an email message to a third party, you give us the third party's contact information, such as email address. We complete the call and retain that person's information to contact them later to solicit them to join our AdCalls service or for other purposes.
Other purposes, eh? Very nefarious indeed; we wouldn't put it past these guys to break you off all sorts of nasty spyware too. Imagine the fun you'll have when all your buddies start getting barraged with credit card offers and they discover your dirty little secret. Et tu, Brutus?
