Why do I need to provide my cellular phone number? And what does YouData do with it?

The issue comes up often during the sign up process, usually in the form of the following 2 questions:

1) Why do I have to provide my cell phone number?
The only reason we require a cellular number is to prevent any individual from creating more than one MeFile in the system. If we did not have such a strict control in place, a few might be tempted to create multiple MeFiles. This would erode the confidence of the advertisers in the quality of the attention they are purchasing, and lower the prices they are willing to bid for your attention.

We encourage consumers to think of your relationship with advertisers as a business. (Corner the market on you.TM) Advertisers are your customers. You want to ensure your customers that your product (your attention) is high quality and "bonafide". By validating against your cell phone, and piggy-backing on all the validation that your carrier did when you got your phone, you are ensuring quality. They pay more for quality. Good business right?

2) What are these guys going to do with my cell number?
Truly nothing. We will never call you or text you without you having explicitly asked for it. We will never give it to anyone else. Advertisers will never see it. We securely store it with the MeFile to ensure nobody else can create a MeFile using that number.

Hope this helps!
