We never see any of your personal information. We do not store any of your personal information or data on our servers. We have no servers.
We do use a service called Flurry. It shows us aggregate information about our users (there are thousands of you). Aggregate information such as total users by country. It does not allow us to narrow down to a single device or user, unless you're the dude in North Korea.
In short, we know nothing about you, Susan.
