Privacy is one of the most common questions people ask us when they discover Lumina.
And honestly, they should.
If a product is helping you understand things like eye strain, posture, stress patterns, and screen habits, it’s reasonable to ask what data it uses, where that data goes, and who has access to it.
From the beginning, we wanted to build Lumina differently.
Instead of relying on cloud processing, Lumina uses open-source, on-device AI models to analyze wellness signals directly on your Mac. We believe the more personal the data, the more important it is to keep processing close to where that data is created.
This carousel explains how we think about privacy, why we made certain technical decisions, and the principles that continue to guide the product as we build.
Your wellness. Your data. Your control.
