The introduction of Lumo aligns with this mission, as Proton claims this AI tool is designed to provide help without tracking users, retaining or sharing their data, and hiding risky functions in closed-source code. Proton has launched a new tool called Lumo, offering a privacy-first AI assistant that does not log user conversations and doesn't use their prompts for training. Instead, Lumo is based on open-source large language models (LLMs) and utilizes Proton's open-source encryption scheme.

Proton is a Swiss company behind proven privacy and security tools and services, including Proton Mail, Proton VPN, and Proton Drive. Lumo's interface resembles those of mainstream LLM services, while the tool supports file uploads with full encryption support. Lumo's infrastructure is located in Europe, where the GDPR applies, so no sensitive data is transmitted to jurisdictions with weaker data protection regulations. Lumo's default setting is not to search online, delete all chats upon closing, and not store conversations on the server-side.
