How Lumo Keeps Chats Private

AI is becoming the most powerful surveillance machine ever built and most people are feeding it their deepest secrets without realizing who can read them. Proton founder Andy Yen joins Bankless to explain how Big Tech captures your identity, why AI chat logs are a privacy disaster waiting to happen, and what a self-sovereign, user-aligned future could look like.
We explore how AI models profile you, why subscription business models don’t guarantee privacy, how Proton built Lumo without retaining user data, and why encrypted email remains the cornerstone of your digital identity. Andy also breaks down EU “chat control,” Apple’s privacy-washing, the crisis of trust in crypto, and the practical steps anyone can take today to reclaim their digital freedom.
