  1. More control over Lumo's behaviour

    I am very sorry, WHY is the "sytem from proton" allowing Lumo

    Write the same answer even when told it's not paying attention.

    it's wrong. So now it will write...

    wait.... Lumo says some ilogical thing: Yes it is x

    i say stop talkign about that because i am asking about somethign else

    Yes you are right i should have

    and to answer the question

    Yes it is x

    Me: stop insisting with something wrong.

    Lumo: yes you are right, i should have, i will not, and then

    and to once agian answer a question you did not ask, or…

  2. File types and size / unsupported file types

    The current file types to upload f.e. images don’t work well and constantly I’ll get the message of “unsupported file type” in the pop-up window and that’s a false flag. They are all files types that Lumo support. I can open those files without any problems within Proton Drive or iCloud. Same issue occurs on Windows desktop, iPhone and iPad. Drag and drop makes no difference.

    The file size is also an issue, limited to 10MB and I have a subscription. An average photo is already more than that. Files stored in Proton Drive can be uploaded with a maximum…

  3. Pull to refresh chats and history

    I use Lumo across many devices.
    Currently I have to force quit iOS and Android apps for them to update with the latest history.
    I would love to see pull to refresh in the history section.
    I would also expect the chat to pull all updates when selected from the history, but this is not currently the case - it does not show activity from another device.

  4. Feature Request: Exclusive Access to Larger LLMs for Lumo Plus Subscribers

    I would like to propose a feature specifically for paying Lumo Plus subscribers: the ability to enable Lumo to use larger LLMs (such as GPT-5, GPT-5 Thinking, Gemini 2.5 Pro, Grok 4, Claude Sonnet 4.5, etc.) for processing queries. The core idea is for Lumo to act as a privacy barrier—protecting user data—while still taking advantage of the advanced capabilities of top-tier models for those who subscribe.
    This enhanced feature should be strictly limited to users who actively pay for Lumo Plus. Free users would continue using the current models and would not have access to this option.
    Lumo Plus…

  5. 1) Lumo Live

    Lumo Live: Let Lumo see through the camera/share screen with permission to better assist users. Also can be combined with:

    Lumomojis: Enhance with animated expressions that reflect real time conversation state, rather than just the generic "speech bubble".

  6. Proton SMS app that uploads incoming sms to a proton drive file or a proton pass note

    A very simple proton sms app that I can log in to my proton account and have it upload all incoming sms automatically (and instantly) to a file on my proton drive (or maybe a note on proton pass).
    We all need a phone number tied to our identity wether that be for banks that only allow that form of authentication or other government related tasks.
    With that kind of app, we could leave one phone tied to our identity permanently at home, and access received sms on any other device through our proton account. That way we would not…

  7. Selecting multiple tasks pressing ctrl/cmd and moving them at once

    Sometimes I have a cluster of tasks planned in a day and I move them one by one to another tim. Instead I would love to be able to press and hold CTRL while I click on these and then move them all at once keeping their relative position to each other in bulk.

  8. Lumo chats are saved

    As I read the Lumo documentation, I find this FAQ: "Are my chats saved?". The answer given is: "Chats are only saved if you use a Free or Plus plan.". Hello? What plan other than the Free and Plus is there? Is the answer to the FAQ actually "yes"? Explain, please.

  9. Lumo - Lessed censored on the cybersecurity themes and subjects

    I'm using Lumo while working in cybersecurity (blue/red team, sometimes in challenges and CTFs)

    Right now, a lot of the time Lumo won’t answer questions that could be useful for us because the system assumes the info might be used maliciously. I get the intention behind that safeguard, but it ends up being a real pain when we’re trying to do legitimate security research, hardening, or authorized testing.

    As the saying goes, “knowledge is power.” When that knowledge is unnecessarily censored, it slows down our ability to protect systems and to understand threats.

  10. Option to start Lumo in a floating window

    As the Android Lumo app does not support Landscape orientation, not even on large screens, it would be VERY nice to have the possibility to launch Lumo in a floating window on systems that supports it.

    On e.g. OnePlus tablets Lumo runs nicely when switching it over to a floating window that can be resized and moved around, BUT there is no way to launch Lumo so it always starts in a floating window.

    Please, add the an option in the Lumo Android app making it possible to have it request a floating window upon start.

  12. Provide a Way to Hide Lumo

    I really hate this AI fad, because it is bad for the environment and will probably result in people losing their jobs and getting replaced by machines that can't actually do them, and is a privacy nightmare, and the models were trained on stolen data, so I would like to be able to stick my head in the sand and ignore it for as long as possible. Can you create a setting that would allow us to hide any mention of Lumo anywhere? I have been using uBlock Origin for this, but I occasionally have to go back in and…

  13. Private Lumo App Store for sharing & monetizing custom “MyLumos” (GDPR-safe alternative to GPT Store)

    Hi Proton Team and Community,

    first of all, thank you for creating Lumo — a privacy-first AI assistant that finally allows European users and businesses to use AI without compromising confidentiality or GDPR compliance. Proton has solved the fundamental problem that all other AI platforms struggle with: trust.

    Now that Lumo exists, I would like to propose the next major step:

    ➡️ A Private Lumo App Store for creating, sharing, and monetizing custom “MyLumos”.

    Just like OpenAI has custom GPTs (and a GPT Store), Proton could offer a secure and encrypted alternative — fully compliant, private, and built inside…

  14. Geolocation for the location field

    It would be so nice for the location field in the calendar to search for and populate a location (e.g. I type in the name of a store & city name, and then it gives me a few options to select, at which point it then replaces what I've typed for search with an address)

  15. Feature Suggestion: Built-In Email Productivity Tools for Faster Daily Workflow

    Many ProtonMail users handle a high volume of emails every day and often need small productivity tools to speed up their work. A built-in panel offering simple utilities like quick text formatting, a snippet creator, a link checker, and an email content helper could make daily communication much faster and easier.
    I’ve created an external toolbox at https://toolinq.com
    that provides similar utilities. If ProtonMail adds a simplified version of these features directly inside the inbox, it could make the overall user experience even more efficient.

    I would like the option to voluntarily share longer chat transcripts for model training when they contain useful corrections or insights. While the existing thumbs‑down feedback works for isolated messages, many improvements emerge only after a series of exchanges. Please add a simple opt‑in mechanism (e.g., a checkbox or toggle) that lets users grant permission for these extended conversations to be used for training, while keeping the default setting to keep all other data private.

  17. Improving response quality and reducing bias

    As it is, Lumo doesn't work very well.

    It hallucinates facts more often than other modern models that also don't access the web. When asked about privacy-related questions, it almost always promotes Proton's services (including ones that don't exist such as "Proton Chat"). I understand that there is an incentive to promote the company's own services, but most people interested in a privacy-respecting LLM, and especially those willing to pay, don't want it to act as a shill for Proton.

  19. Easy button to submit selected conversation as correction

    When I get a known incorrect answer from Lumo, I give it web access and lead it to find and report to me the correct information. There should be an easy button for me to submit just that discrete conversation to proton to correct the underlying knowledge base. All within the Lumo platform. I dont have time to go to another feedback or supprt forum, login again, go back and screenshot the incorrect information, paste that into the feedback platform, go back again and screenshot the correct information, switch to the feedback forum and paste in the corrected info, go…

  20. starting over from the beginning is annoying

    It's very annoying to have to scroll to pick up where I left off in a long chat. Please revert to the way things were before or add a setting for those who want to start the chat from the beginning.
