Therefore, frontend code is responsible for permission checks and privacy-preserving transformations that protect user’s data. We’ll get to that, but first let’s look at some examples of privacy policies and how they can be expressed. Any frontend can access the whole store, regardless of the application user consuming the results.

Apart from library code, maybe your application doesn't have frame pointers either, in which case everything is broken.
