For example, let’s say I want to use a Fitbit. I download the app, enter my real height and weight, but I give a masked email, fake name, fake birthday, etc. I always use the app with a VPN.
When doing an outdoor activity, I would allow my precise location on a run.
Is there really much of a privacy risk if they don’t know who I am?
Please don’t just suggest Gadgetbridge or a similar alternative.
IMO it isn’t so much about knowing who you are, but where you are, what you do, what you like etc. From that they (e.g. G👀gle) will extrapolate a profile and do whatever they want with it - faked data or not.
Furthermore Fitbit belongs to Google. I wouldn’t use a Google product if I was concerned about privacy.
