What can Lumo do and protect you?
Basically, Lumo still fully meets the tasks you expect in an AI assistant: answering questions, summarizing text, or searching for information. However, the special highlight lies in the options designed to protect you.
- Lumo will not arbitrarily “wander” on the Internet. It only starts searching when you actively press the “Web Search” button, giving you all control.
- You can send files for anyone to analyze. Lumo will handle them immediately without storing a copy on their server.
- If you use Proton Drive, Lumo may interact directly with your encrypted files. Everything still happens in an absolute safe environment.
- Chat history is your own. If you have a proton account and choose to save, the whole history will be encrypted, only you read. If you want to “disappear without traces”, the Ghost Mode will erase everything after every session.

Lumo and pledged not to “learn” data
To both ensure performance and maintain security commitment, Lumo uses a very smart architecture. Instead of depending on a huge and expensive AI model, it flexibly chooses between many smaller open source models (such as Mistral Small 3, Openhands 32B …) depending on the task you require. This approach is both fast, economical and effective.

The reason is because a new bill in Switzerland is at risk forced technology companies to supervise users. This is unacceptable for a company that takes security as a life.
By placing a server in Europe, Proton wants to put Lumo under the protection of stricter privacy laws, ensuring your data is safe from all the look.
