I uploaded a picture to Google Maps once. They told me they needed to access my photos to be able to upload the picture.
A week later I get a notification “hey do you want to upload this photograph of a restaurant you took at location x?”. So Google Maps was busy rifling through my photos while I was going about my day-to-day business.
GrapheneOS has storage scopes which make the app think it has full folder/file access but in reality you can choose the exact files or folders to give access. It helps keep invasive apps in line.
Yes, they scan your photos and text and look for reasons to report you to a government agency. They can completely misinterpret or fabricate what you have with no real controls other than good faith.
For somethings I think they are legally obligated to do this. It is creepy.
