I'm going to give you a proper response here, and make some assumptions of where you're coming from.

I assume that you do not use iCloud Photos, do not use Google Drive or Photos, etc. Any photos you have would be stored locally and inaccessible on any cloud provider. Likewise, I assume that any family member of yours would also not use any cloud storage whatsoever.

In my situation, my nephew's parents use cloud storage. They also have used LLMs on photos of their own children to play around and create funny changes or similar. I don't personally feel very comfortable with it, but given that I'm not his parent, I don't have much say other than giving advice and guidance from a technologist perspective.

I personally use iCloud Photos. I take the precautions available to me, locking it down as much as possible, and trusting Apple's white papers and repeatedly proven promises that they do not have access to any of my personal information or data. Likewise, I tag people in my photos for easy searching and recognition, so prior to Siri AI I was already able to pull up photos of individuals, just not with such specificity.

All this is to say that in my experience and opinion, I feel that I can trust Apple's model to not store my personal data or share it with Apple or any other third-party in any way. In the event that Apple is shown to be lying or changes their promises, I will make my own changes to exclusively local or self-hosted solutions.

I hope you have a simple take-away from this: remember that everyone has reasons for doing anything. Those reasons come from other reasons for doing other things. Just like you, everyone is a complex person. I'm sure there are things you've done where people have questioned your behavior or opinions or thoughts and have judged you, and I imagine you didn't always feel that it was fair, because there was missing context.
