Any fitness watch with internet access, by definition, is spyware, yes or yes. Personal and health data are too succulent for large companies not to turn them into profits. There are fitness apps that save data locally, if you want to monitor your health status during your workouts, there is no need for a Cloudservice for this purpose, the data from a workout is not so much that it cannot be saved on a cheap SD card, with much a transfer via Bluetooth to the PC or Mobile, if you want to review this data.

I was forced into using a Fitbit last year, and I instantly went back to my Samsung Galaxy watch when I got the chance. Samsung Health is annoying on iOS, but at least you don't need to send all your data to Samsung in order to use it

Godamnit ! Again I missed out on the data sharing opportunity. My uncle got an apple watch and said that I am missing out on all the cool features. I replied , I dont want anything that connects to internet. He laughed.
