If only this were restricted to Google and Facebook...
Signing up with Polar to get the full functionality of one of their fitness devices is exactly the same - you must agree to everything before you can do anything, nothing is optional. If you want to use their fitness trackers in total isolation then you're good. But you can't connect to anything without first installing a mobile or desktop app. And agreeing to:
- Handing over all your personal details (lots of mandatory data collected)
- Your data being exported outside the EU for processing
- Your data being used to verify your identity, investigate fraud and 'misuse'
- Your data being used for activities not directly related to fitness tracking
- Your data being made available to subcontractors
Some of this you can subsequently revoke but only by contacting customer services...
