They don't tell you up front, but you can't receive verification text messages with the free app. This means 2 things. First, FreeText must be reading all your text messages and you have no personal privacy with this app. Second, they lie about having free texts just to steal your contact information. I'm uninstalling and finding another app to use. Hmm, based on their reply I'd say they don't care about privacy or they'd offer an option to use their service without collecting private numbers.
