Dark app icon for Lumo
All the other Proton apps have an icon for light and dark mode. I think it would be great to have a dark icon for Lumo since it only has a light icon.

Add a usage tab to Lumo
Lumo should provide a dedicated usage tab where users can see their daily resource consumption in real time, including Max model requests, image generations, and any other rate-limited features.
Lumo enforces daily limits on features like the Max model and image generations, but these limits are not surfaced to the user. The only feedback is an automatic fallback from Max to Lite when the daily Max cap is reached. Users have no way to check how much of their quota they've used or how much remains, making it difficult to manage their own consumption throughout the day.
It would be…

Lumo payment separate from my other products
Currently, to sign up for Lumo+, you must add it to your current subscription, with the same time period, so if you have a 1-year subscription, you have to pay for 1 year of Lumo, if you have a 2-year subscription, you have to pay for 2 years of Lumo up front.
The other option is to lose all the discounts on your main Proton account in order to activate Lumo+ for the new term.
For example, if you have a 2-year Duo subscription (€11.99 per month) and you only want 1 month of Lumo for both users, you have…

Please add Biometric (fingerprint) unlock to Lumo
Please add Biometric (fingerprint) unlock to Lumo (and Calendar), it and Calendar seem to be the only Proton apps that do not have this feature.

Please list reference links for various parts of the answer
It would be great if the Lumo AI would include web links with all answers referencing where answers came from and/or where further direct research could be carried out. Perplexity offers this functionality and I really like it because it allows you to put a little more trust in the quality of the answers.

Reoccurring tasks
I would like to see a feature where you set up a job for Lumo, like "summarize the news" (ofcourse with a more finegraded prompt), using web search, with an option to make it reoccurring, like a calendar event, for example every day at 7am.
Lumo would then message me on its own, with the latest findings.
This could be used in many ways.24 votes -
Use better open-source ai models.
Dear Proton Team,
I would like to propose integrating several high-quality open-source AI models into the Lumo platform. These models align with Proton’s core values of privacy, transparency, and user data sovereignty, while offering excellent performance and flexibility.
The recommended models include GPT-OSS 120B, LLaMA 3, DeepSeek-V3, Mistral 8x22B, and BLOOM. These models stand out because they are open source, enabling complete self-hosting and customization. This means Proton can maintain full control over user data, keeping all processing within secured European data centers, aligned with Proton’s zero-access policy and strong privacy commitments.
GPT-OSS 120B offers powerful capabilities close to proprietary…

Import Chat to Project
I've already had a number of chats that I realized would be best in a dedicated Project, but there's no easy chat-import function. Thanks to Lumo's report, I see it's a privacy-protection feature, so I'm quite thankful for that. But at the same time, perhaps a good balance would be to have a selective-transfer function, we can cause check-boxes to appear beside all prompts, Lumo-replies, and chat-knowledge files, so we can choose what to copy and what to allow for deletion, then paste it into a Project?

Add support for Skills
I suggest Proton Lumo adopt Skills from (for example, skills.sh) as a lightweight way to package predefined trusted, domain-specific knowledge into small, reusable text modules. In practice, a Skill gives Lumo a clearer “expert lens” for a given topic, so instead of offering broad generic answers, it can respond with guidance that is more grounded, consistent, and relevant to the user’s actual question.
This matters for Proton Lumo because users will judge the product on whether it feels genuinely helpful in everyday moments. Skills can make Lumo better at explaining complex topics in plain language, guiding people through sensitive or…

Lumo integration in meet for meeting summaries & transcriptions
It would be great if the upcoming meet app would have an option to summarize and transcript meetings.
Making this possible with a trustful AI like Lumo would be amazing (and I think no one else has a meeting transcription feature with a trustful AI)23 votes -
ghost mode (and/or web search) saved
Hi there,
after I started using Lumo for a while, I like to use the ghost mode by default. However, under current setting (both on webpage and on Android app) I have to switch Lumo to ghost mode (and turn on web search) every time. Can we make it a setting to use the ghost mode (and/or web search) by default? It will save a lot of effort.
Thanks.
By the way, I like Lumo very much. After I found it, it became my main AI assistance.

Emphasize that user data is never used to train AI models
From the Lumo "Getting started" webpage: "Information you enter is never used to train AI models." I think this should be emphasized more and expounded on, perhaps giving scenarios using both Lumo and other AI chatbots. (It looks like a no-brainer choice, to me, of which bot to use given that all the other ones (Maybe not DuckAssist?) exploit you and your data/thoughts.) While the privacy mantra of Proton is well-known and can be assumed, that's no reason to be subtle.

Import chat history from other LLM
Please allow us to import chat history from other big commercial cloud hosted LLMs to ease transition and not lose all the information prior LLMs gleaned from us, what we are doing, what is important to us, etc.

Wider response area (smaller margins)
On a tablet or portrait monitor, the response should take up the full width - currently there is a lot of wasted space on each side, with the response in a narrow center block.
On larger screens, I still find it too cramped - especially with rich results such as tables. Tables are often very compressed and hard to read.

Implement TEE-Based Confidential Computing for Lumo Inference
Feature Request: Implement TEE-Based Confidential Computing for Lumo Inference
SummaryLumo's current security model does not protect user prompts during inference — the window when plaintext is most exposed and most exploitable. This is not a theoretical concern; it is a documented architectural gap with a proven, production-ready solution that a direct competitor is already shipping.
The ProblemLumo's security model blog post dismisses inference-time privacy by framing the only alternative as homomorphic encryption (HE), correctly noting it is impractically slow. However, this framing is a false dichotomy.
As Proton's own documentation acknowledges:
…"prompts are asymmetrically encrypted so only the19 votes
