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.
Creepy, gross and repulsive.
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.
