About Lumo by Proton
Lumo is a privacy-centric artificial intelligence service developed by Proton AG, the creators of Proton Mail and Proton VPN. Based in Switzerland, Lumo is built as a 'zero-access' encrypted AI assistant, ensuring that the service provider cannot access or read user conversations. It serves as a confidential alternative to mainstream AI tools that typically track and record user data for model training. The service operates under strict Swiss privacy laws and is owned by the Proton Foundation, a non-profit organization. By leveraging the same security principles as other Proton services, Lumo aims to provide a conversational AI experience that prioritizes user anonymity and data sovereignty. While it functions as a SaaS model, its core architecture is designed to minimize data collection and prevent unauthorized data exploitation.
