Lumo by Proton

Lumo is an AI-driven chat application developed by Proton AG, the Swiss company renowned for its privacy-focused services like Proton Mail and Proton VPN. Launched as part of Proton's expanding ecosystem, Lumo emphasizes user privacy and data security by utilizing zero-access encryption for chat histories and operating under strict Swiss privacy laws. Unlike many mainstream AI tools, Lumo is designed to minimize data collection and ensure that user inputs and generated outputs remain private.

The product's development and infrastructure are centered in Switzerland, benefiting from the country's strong legal protections for digital data. As a software-as-a-service (SaaS) product, its 'manufacturing' refers to its software engineering and server hosting, which primarily occur within European jurisdictions to maintain the brand's commitment to neutrality and security. Proton AG remains an independent company, largely owned by the Proton Foundation, ensuring that it is not beholden to traditional venture capital interests that might compromise its privacy mission.
