See, I wen’t one day through my google and apple accounts. I saw that they auto upload photos and videos they think are important to me and keep them there. Mostly memes and screenshots, not a single nude from my phone and I have a lot of nudes on it. I still don’t trust them so I’ve disabled all syncs, backups, and sorts. And yet Google still backups some, even that I explicitly disabled those. Apple on the other hand didn’t upload or backup anything since I made those changes… buuuuut, when I connect my phone to a PC and give it permission to connect, and I open my camera folders all hidden pictures and videos are there and visible. I can’t go through my photos on a PC with anyone, because of this. Google and Apple had a lot to work on their privacy and security, tho. Especially Google. But bare in mind that a lot of the apps you give permission to read and write your albums, backup them on their servers for quick access. Especially apps like snapchat, tiktok, etc…
