why do you think people are willing to have their personal data sold to someone else? if I got it right, that's what you're gonna do
All personal data is encrypted. It's not connected to you as a person. Basically.
how am I gonna know that my info doesn't get into the wrong hands?
For a user it only means that he is going to get highly personalized and more accurate offers. No one is going to use your data against you there's just no way to get past the encryption. No wrong hands here too.
we'll see about that

Just wait until it's ready we promise there's no hidden catch. The platform is only designed for your convenience.
Can you guarantee that? I mean, except just promising. Promises are not enough, since we even see data being sold by major companies, although their prosecuted for that.
