BYG — Black / Yellow / Green

BYG is Fidune's decision model.

Before any piece of your information, or any action, leaves your devices, BYG gives it one of three colours:

• Black — it never leaves.
• Yellow — it leaves only after you approve the exact content.
• Green — it's allowed without asking.

It is careful by design. Anything it can't recognise counts as sensitive, and the most sensitive part of a request decides its colour. BYG decides the colour; ordinary code, not the model, enforces it at the one place where data can leave your devices.

BYG is still being built and tested. We'll publish how we test it.
