If people were worried about Facebook 'listening to your phone' to show you ads (it wasn't) why are they not terrified of what sports betting apps share with everyone?
Welp, just learned Google nerfed the Google Photos API in 2025.
3rd party apps basically can't get access to a users Google Photos library.
You have to have the user manually select which photos they want, and you have to download them to the device to actual keep access.
