[Xposed Framework Modules] hikaritenchi:
Looks like I was mistaken about the 1 week thing, that's one of Google's messages. In any case, these are the calls being made, with my information removed:

Making 'device_session' request to https://apps.gpshopper.com/mobile/220/10/2500/device_session:

Making 'device_profile_save' request to https://apps.gpshopper.com/mobile/220/10/2500/device_profile_save:

Registration ID successfully saved to the server.

Device ID is actually regenerated with each install, so I'm not really sure what is going on here. If you believe it's stored somewhere else, you can either:

1. uninstall confirmed and use SD Maid to clean up tombstones

2. here's a list of files that the app looks in, you can see if there's something of interest here.

I guess one last question, did you add confirmed to the list of blacklisted apps in rootcloak before you started the app?
