Fantastic app. It starts in simple view, easy to use for a quick check, and has some advanced options available without having to navigate through menus and settings. I loved the graph where we can zoom not just x-axis but also the y-axis!

Demands permission to share your data with advertisers. There's no "reject all" option, all you can do is "accept all" or go through every single vendor. This is either illegal or a serious grey area, i'm not sure.
