Don't know why they hide their pricing plans but you have to sign up to get to see the pricing plans when you try to add a website to your account.

There is a free plan for less than 30k pageviews per month and 3 month data retention, $4.95 for 100k and 6 month retention all the way up to 179.95 for 10,000k pageviews and 36 month data retention. There are added features for the more expensive plans too.
