Does anyone have an opinion on the Angel Sensor activity tracker?

I want to buy an activity tracker for fitness. But the main products out there, like FitBit, seem kinda well evil to me (in that you have no right to your own data, and have no idea what who they are going to sell it to).

The only product I could find that seems less evil is this one, the Angel Sensor M1:

Has anyone heard of them or used their product? They are apparently IndieGoGo funded. I am slightly concerned that the product is just vaporware.
