About Lumo
Lumo is Proton's privacy-first AI assistant built for users who refuse to trade confidentiality for convenience. Conversations stay encrypted and confidential, with no training on user data, no advertising profiles, and no tracking. Lumo delivers general-purpose chat, writing, research, and coding help inside the Proton ecosystem already trusted by millions for email, VPN, and cloud storage.
Built on open-source language models and run on European infrastructure, Lumo encrypts every chat so that even Proton cannot read user conversations. Sessions can be fully ephemeral, with no long-term storage by default, and the assistant integrates with Proton Mail, Drive, and Calendar so users keep one zero-access identity across every Proton service.
Key benefits:
- Zero-access encryption keeps conversations private from Proton and third parties
- No training on your data so questions never feed external AI models
- Ephemeral chats leave no persistent record unless the user opts in
- Open-source models running on Proton-operated European servers
- Proton ecosystem integrates neatly with Mail, Drive, and Calendar
- No ads, no profiling consistent with Proton's long-standing privacy mission
Lumo is operated by Proton AG, headquartered in Geneva, Switzerland, and runs on Proton's own European data centers under strict Swiss privacy law and GDPR. Proton is ISO 27001 certified and independently audited, offering a sovereign alternative to US-owned chatbots for EU businesses and privacy-sensitive individuals.
Ideal for journalists, lawyers, healthcare professionals, and privacy-conscious users who need a capable AI assistant without surveillance baggage.
Why choose Lumo over Gemini?
The decisive argument is data jurisdiction. Gemini is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Lumo removes that overhead. As a Switzerland-based provider, it operates under Swiss FADP + GDPR for EU users, and data stays in Switzerland, which the European Commission recognises as offering an adequate level of protection. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
