> The latest report suggests that the erased and sold iPad is somehow restoring old photos from an Apple ID that is no longer signed in to it. The Reddit user says the photos that are reappearing are from 2017, which is in line with similar reports. The images were initially taken on an iPhone, and so had been synced to the iPad via iCloud Photo Library before the iPad was wiped and sold.
This is probably iCloud related, I guess that's what you get for using unencrypted storage.
Ente is finally a realistic encrypted alternative for Google photos / iCloud if you are looking for one, it's also open source, but it's yet another subscription and it's not cheap at all.
