Bringing Humanity and Privacy to AI

I defined Lumo’s brand strategy and story, bridging Proton’s privacy-first DNA with a more approachable AI expression.

The name Lumo (from lumen, “light”) guided a visual universe built on clarity, guidance, and trust — a bold, purple-driven identity marked by the keyhole symbol of protection and control.

I designed a dedicated set of Emojis, called Lumojis, expressive emojis that extend Lumo’s personality into every interaction.

They add playfulness and warmth to conversations, turning functional feedback into emotional connection.

The Lumo app is designed as Lumo’s home — a quiet, immersive environment that users step into.

Each screen reinforces a sense of comfort and confidentiality, where Lumo welcomes you into its world.

We designed Lumo Incognito, a mode for ephemeral conversations, extending Proton’s commitment to discretion.
