You keep the interface simple, but the law has to be invisible to the user, not an obstacle. Build it around a modular consent system: every data point has a “yes‑no” toggle, and each toggle is backed by a one‑sentence explanation that pops up on click. Use an opt‑in default for any sensitive data, and let the system audit every change so you can prove compliance at a glance. Make the privacy policy a short, bullet‑point summary and link it to the relevant toggle; that way you’re giving users control without burying them in legalese. Remember, a minimalist UI can be a fortress if you put the right controls in place.
