Well, if the data is never leaving your wrist you will never see any graphs and never actually enjoy the great things a training watch gives you.

Sure they may store my personal data and I would prefer if they didn't sell it to any third party. I would also prefer a product which can store information locally on the phone but never sync it to the "cloud".

The thing is, there is no such products because people are stupid and would be furious if they switch phones and their data was lost on them because they didn't understand that the data was only stored locally and never left the device.

I would buy such a product, if it existed, but it don't AFAIK. Fitbit stored the same amount of data as Withings do, it's just because Google bought them that people are worried.

Withings is basically a rival to Fitbit and since you don't want the data to ever leave your wrist, this sort of product is clearly not for you.

I think the point I was making is not whether the data is allowed to leave my wrist, but to "let me be in actual control" of my data.

In a world of USB sticks, micro SD cards, and $5 Raspberry Pis, I can imagine human-friendly ways of sharing data that don't involve tethering my wrist to someone else's computer.

"[P]eople are stupid"? I'd like to give people a bit more credit. They can move data around, without surprise or fury: plenty still use Ethernet cables, USB sticks, iPod Shuffles, Blurays, etc.
