Is there a FOSS Android app that tries to collect all data it can and then show it to you?
For example, I'm trying to find out how isolated the work profile on my phone is and whether it shares identifiers with the main profile, but in general I'm thinking of buying a new phone and keep Google et al. as far away as possible, but I need to understand exactly what data these companies have access to.
Although I don't know who much info you can get about the requests from it, I only used it to find the culprit and since it was an easy decision I uninstalled it, I didn't had to check what data was being collected.
