Not sure I agree entirely. The actions I take are definitely data about me.
Also, in many jurisdictions data that could be combined (even in the future) with other data to identify you or something about you, is considered personal data.
For example, Device ID is AstridWipenaugh’s device and they use the app in the morning.
(I don’t like this kind of data collection either fwiw, not trying to defend them or anything)
On Android at least, device id’s are unique per app, and reset when you reset your phone to factory. In theory they can’t use this data to cross-track you personally, since every service that uses a device id has a different one for the same user.
They can probably still build up a pretty accurate profile of you based on other data they collect though.
