This is definitely something we need to address on the site, and we'll update it in the next few days. We think showing ads to kids or selling their personal information is completely unacceptable and will never do that. The way we plan to make money is though the classic fremium model - the basic features (including the ones we have right now) will be free, but we'll ask parents to pay for premium features. Right now, carriers charge $10/month for GPS and $5 for call limits. We want to give these away for free and provide parents with real value they feel good about paying.
