Software engineer Vishnu Mohandas decided he would quit Google in more ways than one when he learned that the tech giant had briefly helped the US military develop AI to study drone footage. In 2020 he left his job working on Google Assistant and also stopped backing up all of his images to Google Photos. He feared that his content could be used to train AI systems, even if they weren’t specifically ones tied to the Pentagon project. “I don't control any of the future outcomes that this will enable,” Mohandas thought. “So now, shouldn't I be more responsible?”
The site (TheySeeYourPhotos) returns what Google Vision is able to decern from photos. You can test with any image you want or there are some sample images available.
Idk about viewing but for automatically synchronizing pics (or any files really) from android to other devices syncthing is great. Its p2p so doesnt require setting up a server but its not like a "cloud storage" where you download on demand, instead it will actually write changes to disk on the other end which is actually great in case you lose your phone.
