On the “meta” user profile yes, blocking trackers is more important than hiding my IP for that user profile

I use GrapheneOS, I run Instagram in a seperate user profile within its own storage scope alongside an app called “Tracker Control” and block most trackers that way.

I can’t answer about exporting data but having just done some research the 2 best options I have found for a privacy focused solution (open source) are either:

Bangle JS https://banglejs.com/

PineTime https://www.pine64.org/pinetime/
