How can I make photos that I take on Android private?

I take a photo. It's automatically saved in "Photos" which is Google's, which is on Android, which is Google's, which I'm signed in to to use Android.

Yes I've got backup disabled, but really, we're not just going to trust they will completely keep their eyes off.

So how can I take photos on my phone and complete. Keep if off prying eyes?
