Lumo is a new AI assistant from Proton that gives users full control over their data. The tool operates without logging, data sharing, or using conversations for training purposes.
Proton, known for secure services like Proton Mail and Proton Drive, introduces Lumo: an AI assistant that prioritizes privacy. While many existing AI systems use user data for training purposes or advertisements, Lumo does not keep conversation logs, share data with third parties, or use input to train its language models.
The AI assistant is built within Proton’s existing privacy ecosystem, which operates from Europe and falls under EU privacy legislation.
Open source
Lumo uses open-source language models running in Proton’s own European data centers. All chats are encrypted by default with zero-access encryption, meaning even Proton cannot access stored data.

Users can use the tool anonymously without an account, or sign up to securely store chat history, readable only locally through encryption.
Applications
Lumo is designed for various applications, from summarizing legal documents to rewriting personal emails. Additionally, the assistant offers several features that cater to privacy-sensitive work scenarios:
- Ghost mode deletes a chat once the window is closed.
- File analysis allows users to upload documents without them being stored on servers.
- Web search is available but optional.
- Proton Drive integration enables secure file sharing in conversations.
Lumo is immediately available for free via Proton’s website, and there are apps for Android and iOS. Users who want to ask more questions or desire additional features can upgrade to a paid version with extended capabilities.
