That looks like a very bad recipe to get burned with your private data escaping your control. Just the choice of components alone is enough to give me the shakes but that gets compounded by a design that can only be described as 'insecure out of the box'.
This is a great research project/experiment but I would really suggest you pause before you give it actual data.
