NO ONE sees your FAFSA except the places where you submit your FAFSA. And each school sees only THEIR school…not any of the other places.
Why are you so concerned about this? Colleges DO know that students apply to other colleges. What do you think would happen?
But…doesn’t matter because younare worrying for NO reason.
I will say…do you plan to apply to an instate CA public universities where you can continue to use your state college funded grant money? If so…do not miss the deadline for sending your FAFSA. Don’t miss it.
