  1. It would be interesting to be able to buy a single month of Lumo services, instead of a full year.

    I would buy individual months at certain times of the year. The whole year is too much for me.

  2. Make the highlight for today's date bigger

    If you view the calendar in month view, and put at least 4 events per day for the entire month, it can be very hard to easily find where today's date is.

    Currently it's just the number inside the date box that is boxed/highlighted and this gets lost when there are lots of events in a given month.

    Request: Simply just make it obvious. Or better yet, instead of boxing just the number, why not highlight the entire date box, and change its background colour to your primary colour instead? pls and thanks

  3. Timestamp

    I would find it helpful to have access to a timestamp for each chat input. Some of my chats go over months and sometimes I would like to know when I input a specific information.

  4. Implementation of sorting options for Projects, Chats within Projects and additional sorting options for All Chats in Lumo (alphabetical as

    Thank you to the Lumo team for building and continuing to improve upon such an easy-to-use privacy-respecting assistant, and for Projects in particular, which have become central to how I organise ongoing work.

    I would love to see additional sorting options for the Projects list, the Chats within the Projects themselves, and All Chats that have not been assigned to Projects. If possible, these could include:

    - Alphabetical order (ascending and descending).
    - Manual reordering via drag and drop.
    - Retaining the current 'Last updated' and 'Date created' sorting defaults in All Chats for those who prefer them, and adding…

  5. 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.

  6. Custom Lumos usability (quick selection and/or prompt)

    In order to make the use of custom Lumos more efficient (I still catch myself prompting instructions every time instead of selecting the relevant custom Lumo) present custom Lumo icons in the tool bar of the prompt window so i can activate them with one click.
    Maybe allow to 'pin' certain custom lumos for folks that have too many ...
    Mentioned in other posts: a prompt that activates a specific custom lumo would be great too.

  7. Duration of appointment in Proton Calendar for 45 and 75 minutes

    Thank you for the security and privacy of Proton Calendar, including Booking pages.
    In Proton Calendar, duration of appointments can default to 30, 60, 90 minutes. Is it possible to add 45 and 75 minute duration?

  9. Transparency Gap in Lumo — Model Disclosure Consistency Issue

    Dear Proton Team,

    I'm writing as a supporter of Proton's privacy mission who deeply appreciates what you've built with Lumo. The zero-access encryption architecture, European datacenter infrastructure, and commitment to keeping conversations off training pipelines are exactly what the AI privacy space needs. However, I've identified a significant inconsistency in transparency that undermines this otherwise exceptional privacy-first positioning.

    THE CORE ISSUE

    Currently, Proton markets Lumo as using "open-source language models" without disclosing which specific base models or model families power the service. This creates a transparency gap between your stated values and your actual disclosure practices.

    WHAT IS CURRENTLY DISCLOSED:…

  10. Add a copy icon for users own prompts

    Add a copy icon for the users own prompts in the chat. Some of us like to copy and paste question and answers into Obsidian for example. It saves having to ask again in the future. We can copy the response but often if copying and pasting that some kind of context is needed sometimes hence being able to use/paste our questions/prompts into a note app etc.

  11. is LUMO sharing details with US Government on for US defence industry?

    is LUMO sharing details with US Government for US defence industry? If this is the case, we'll stop using it. See Anthropois canceling..and Chat GPT, X Grok, AWS and Meta complying to US Government requests. Had Proton been getting these requests and what were their response?

  12. Make all Project Knowledge files searchable and selectable with @ and selectable with @

    When using Lumo Projects with files linked from Proton Drive, all files can appear correctly under Project Knowledge, but only a subset of them is available when typing @ in the chat.

    This creates a usability problem: a file may clearly exist in Project Knowledge, yet it cannot be found or explicitly selected through the @ mention interface, even when typing part of its exact filename.

    Because Lumo also uses smart retrieval, it is currently difficult to understand whether:

    • the file has been fully indexed,
    • indexing is still in progress,
    • indexing has failed,
    • or the @ autocomplete simply shows a…

  13. Farb-Funktion gratis zur Verfügung stellen bitte

    Hallo,
    wäre es möglich die Farbfunktion von Kalenereinträgen kostenlos zur Verfügung zu stellen, bitte? Es hört sich etwas absurd an, wenn ich mit Leuten über Alternativen zu Google Produkten (u.a. Kalender) rede und ich dann erklären muss, dass man für das Einfärben von Kalendereinträgen 5€ im Monat zahlen muss. Im google Kalender geht das einfach und gratis. Es ist somit halt echt schwer mit dem begrenzten Funktionsumfang von Proton Kalender Leute zum Umsteigen zu bewegen...
    Deshalb meine Bitte: Stellt die Farb-Funktion von Kalendereinträgen bitte gratis zur Verfügung, vielen Dank.

  14. recurring

    It would be great to edit the current and upcoming events only, without messing up past events. The overwriting all previous modifications to a recurring event makes it very inflexible to use.

  15. Our Privacy due to Apertus and similar to be clarified

    Hello

    WARNING: there is only 1 single suggestion: when an update, or system or otherwise is added, Lumo needs to be aware of.

    Everything else i write, is me explaining the context, why, and more. But please remember that all this is for the above suggestion.......... Because i asked lumo to do a summary and it added "suggestion" that i did not say (like usually, adding extras....) but they are on the point, and can, hopefully, help everyone understand the suggestion better.

    HERE IS COPY PASTE FROM LUMO:

    On 11 September 2026 I used the thumbs-down button to report an…

  16. "Get Lumo+" Confusing/Misleading on Proton Family Subscription

    I find the "Get Lumo+" button in Lumo very distracting/confusing. I already have Proton Family, which I understand already comes with Lumo Plus (I have confirmed Scribe acces in my Mail). But this button shows me a dialog that tries to upsell me what looks like 6 additional AI licenses?

    It doesn't really state that I already have Lumo Plus for my current 6 seat Proton Family plan.

  17. Disable animated background when WebGL is disabled

    Currently the web app crashes when WebGL is disabled through NoScript (or in Tor Browser's "Safer" setting), but only when the animated background is enabled. Therefore the animated background should be disabled when Lumo finds that WebGL is disabled.

  18. I love using Lumo. But have difficulty with the small gray scrollbar. Please make that in a contrast colour or much much bigger.

    I love using Lumo. But having difficulty with the small gray scrollbar. Please make that in a contrast colour or much much bigger. I do not want to squint every time I have to scroll up and down. Recently I asked Lumo and he suggested settings. So by trying myself, I realized something and succeeded in making the background white. That helped a bit. But the bar is still very small. Can you please fix this.

  19. Lumo Branding / Design

    Lumo Logo / Design / Branding

    Suggesting an overhaul and alignment with the Proton family of product.

    The current choice has no cohesion with the established design language.
    Unless it is design for an audience of kids and adolescents specifically it feels
    playful, cute and disjointed.

    Surely kids and adolescents are not the primary market for the company's
    flagship AI product. Given the importance and relevance of AI a bit more
    thought could very well go into the branding here.

    As huge Proton fan and customer of many years I frequently wonder about
    the design choices. Form, function and aesthetic…

  20. Learning Feature on Lumo

    I would love to see Lumo receive a learning feature similar to ChatGPT or other AI tools. The idea would be that Lumo could help users study by generating learning materials such as quizzes, flashcards, or practice exercises automatically based on input. This would make Proton not only a privacy-focused productivity suite but also a helpful tool for education and personal development. Adding such a feature would make Lumo far more versatile and improve its value for students and lifelong learners.
