  1. Implement TEE-Based Confidential Computing for Lumo Inference

    Feature Request: Implement TEE-Based Confidential Computing for Lumo Inference
    Summary

    Lumo'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 Problem

    Lumo'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 the

  2. Keyboard shortcuts for Proton Calendar

    Would love to see functionality (like with Google Calendar), where pressing "m" on your keyboard allows you to toggle to a monthly main calendar view, "w" shows a weekly view, and "d" shows a daily view. It's a small thing, but I use it often with Google and it makes using Proton Calendar feel more friction-filled. Thanks!

  4. Feature Request: Persistent "Reasoning View" for Transparency & Collaboration

    Hello, Proton.

    Fair notice: I did allow Lumo to aid my crafting of this feedback and suggestion. I thank you folks for all that you do!

    Susana

    To: Lumo Product Team / UX Design From: Susana [User]

    Observation: Following the recent UI update (April 2026), I noticed that Lumo briefly displays a numbered list of internal reasoning steps (e.g., "User is asking X, analyzing data Y") before posting the final response. While this currently disappears quickly, it offers a unique glimpse into the AI's logic.

    Insight: Rather than viewing this as a transient artifact, I believe this "reasoning trace" could…

  5. Poll a list of RSS feeds on a schedule

    I'm tired of traditional RSS apps. They need to evolve.

    Add an RSS polling feature to Lumo to schedule regular cadences of getting new articles from a list of RSS feeds. And I should be notified when the articles are available.

    I would use this with a prompt that would sift through the list of articles for me and only surface the ones I'd be most interested in.

  6. App Design and Usability

    The Lumo app has some design inconsistencies. When you tap any button, a blue border appears, similar to older versions of Android. Please update the app to make it run more smoothly; to me, it seems slow and unpolished too (in terms of both design and usability).

  7. No restrictions for files made by Proton´s own tools

    I can understand some restrictions like upload sizes (although even for unlimited subscribers they are way too small to be useful), but at least have unlimited features for Proton's own tools like Sheets and Docs. That would further incentivize users to use them as well.

    The 10 MB limit is likely an outdated restriction that doesn't reflect Proton's current technology. Since Proton already has a secure storage system (Drive) and collaboration tools (Docs/Sheets), the technical challenge isn't processing files, but integrating them directly into the chat. In a "Unlimited" tier, Lumo could read and analyze files directly from Drive without…

  8. Voice of the Proton Community app

    DISCLAIMER: It's my ideea but due to going back and forth for hours, i had enough. As such, sorry proton and anyone else, the "corrected version" from Lumo is "wierd" but i hope i make it clear that (sadly for me....) it's still better whatever rambling i wrote. AKA proton or whoever, please ignore any "wording" and just focuse on the idea/suggestion. Since sadly it might not be clear why i suggest this app, aka for everyone to have a (well due to Lumo) have an easier, faster, more accurate, so on and on. Whatever, it's explained so here it…

  9. jump to prompts in long chats

    I love bouncing ideas with Lumo Ai and seeing how resourceful it can be in realistic or emotional scenarios. In lieu of this, the chats can get really long and it would be nice to be able to jump between prompts instead of having to scroll all the way up. I noticed that DpSk has that feature and it would be very helpful.

  10. Implement Bias Mitigation for Chinese Open-Weight Models (Qwen, Kimi K2)

    As noted in Lumo's Privacy Documentation, the system currently routes queries to several open-weight models, including Qwen and Kimi K2. While utilizing these models supports cost-efficiency and open-source diversity, research (e.g., NDSS 2026, "S1761") indicates they contain significant internal censorship and narrative engineering aligned with authoritarian state interests.

    Proton’s core mission is to champion digital rights, encryption, and freedom against state surveillance. However, deploying models with embedded propaganda or censorship mechanisms creates a contradiction:

    • Cognitive Risk: Users may receive subtly altered information or suppressed viewpoints on sensitive geopolitical topics (e.g., HK, Taiwan, human rights).
    • Value Misalignment: This conflicts with Proton's…

  12. Allow Reordering of Projects

    Currently, the five most recently created projects are listed under the Project section; however, these may not be the most frequently used. It would be great if we could rearrange them to allow easy access to favorite projects.

  13. Show time zone names (or custom labels) in the calendar view, not just GMT offsets

    When two time zones are enabled, both columns are only labeled with their GMT offset. Example: Europe/Vienna and Africa/Johannesburg both display as "GMT+2" during European summer time — completely indistinguishable. In winter the offset differs by one hour, but "GMT+1 / GMT+2" still doesn't tell you which column belongs to which zone.

    Please show one of the following next to (or instead of) the offset:

    The IANA city name (e.g. Vienna, Johannesburg), or
    A user-defined label per zone, or
    The standard abbreviation (CET/CEST, SAST).

  14. Calendar Booking buffers

    Calendar Booking. I just found this feature on Proton and LOVE it I've been trying to use 3rd party booking tools. The enhancement it needs is to be able to set buffers before/after events on the calendar so they are not back to back. Other booking tools have this feature and found it very helpful.

  15. Voice typing in Ubuntu Linux and/or Firefox

    It would be great to have at least a web-based voice typing for Lumo on Firefox for those who, like me, are using Linux OS's. I'm on Ubuntu but am forced to another IA b/c of the lack of voice typing on LUMO. 😭

  16. To make Lumo more human

    Subject: Proposal: A "Dual-Loop" Architecture for Next-Gen LLMs Inspired by Neuro-Mechanical Models

    Dear Research and Engineering Team,

    I am writing to share a conceptual proposal for a new architectural approach to Large Language Models (LLMs), inspired by the neuro-mechanical theories of Lee Kent Hempfling (specifically the distinction between Short-Term and Long-Term memory loops).

    While current LLMs excel at pattern recognition and statistical prediction (effectively acting as massive Long-Term Memory systems), they lack a mechanism for inhibition, self-correction, and proactive intent. This proposal suggests a "Dual-Loop" architecture that could significantly reduce hallucinations, bias, and reactive behaviour.

  17. 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…

  18. Responsive email templates

    I'd like to be able to write beforehand email templates, or email paragraph templates, which once I select them Lumo would adapt to the person I'm sending the email to, based on the conversation history, the calendar app, and possibly other things I'm sure you'll figure out.
    e.g. : I have an appointment confirmation template ; Lumo will automatically adapt the tone, gender, name, date, time, place, etc.

  19. Van AI to PI*

    Subject: Feature Request: From "AI" to "PI" – The Solution for Persistent Context
    Dear Proton & Lumo Team,

    I am writing to you as a user who values Lumo for its privacy, but who is stuck on a fundamental design issue: Digital Amnesia.

    My Context: After a serious motorcycle accident in 2008 (traumatic brain injury, coma), I had to rebuild my entire life from scratch. For me, continuity is not a luxury—it is a necessity. When Lumo "forgets" who I am with every new session, it feels like losing my identity all over again.

    The Problem: The Bell Without the…

  20. Ability to disable "same output"

    Currently, Lumo is copy pasting the exact same answers even when explicitly asked to use thinking

    insted of using thinking, it just outputs the same answer

    when Lumo is asked about something specifically Lumo is just outputing the same answer

    Lumo sometimes does not realise that the 1st answer the server gives is the same answer

    Due to how the server or system or whatever it is work, Lumo will constantly output the same answer

    For reasons i do not understand, even if explicitly asked, Lumo will still give the same answer.

    On mutiple test, over mutiple weeks, me insisting…
