I'm not familiar with iPhone picture storage. Are the pictures automatically sync'ed with cloud storage? I would assume (even if I don't like it) that cloud providers may be scanning my data. But I would not expect anyone to be able to see or scan what is stored on my phone. Incidentally, I work in computer vision and handle proprietary images. I would be violating client agreements if I let anyone else have access to them. This is a concern I've had in the past e.g. with Office365 (the gold standard in disregarding privacy) that defaults to sending pictures in word documents to Microsoft servers for captioning, etc. I use a Mac now for work, but if somehow this snooping applies to computers as well I can't keep doing so while respecting the privacy of my clients. I echo the comment on another post, Apple is an entertainment company, I don't know why we all started using their products for business applications.
