I made a rollyo search engine for New Zealand news websites.

So you can search all the major national news sources in one go. Cool, huh?
Check out this piece of information in their privacy policy:
"We may use information about you for our own internal purposes, such as to estimate our audience size, measure aggregate traffic patterns as well as to understand demographic, customer interest, and other trends among our users. We may outsource these tasks and disclose personal information about you to third parties, provided the use and disclosure of your personal information by these third parties is restricted to performance of such tasks."
So Rollyo is basically a front for collecting marketing information about its users and passing it on to advertising companies. I wonder how much money they're making off this venture?
