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.
Pseudonymous just means it’s slightly more annoying for you. Given the reidentification that happens readily to “deidentified” information you’re absolutely getting that information tied back to you in some data broker database.
