Increase lumo chat message count past 250
The limit of 250 is too few. The ability to hold more, say 1000 per session or more than 250.

Improved visibility of the Internet search icon in Lumo
I find the current icon for the integrated Internet search in Lumo difficult to distinguish, especially with dark themes or low screen brightness. I suggest introducing a clearer, higher-contrast icon that automatically adapts to the selected theme (light/dark).
Possible implementation:
A minimalist magnifying glass icon with a subtle frame that is highlighted in color when search is activated.Optional: A short tooltip display (“Start/stop search”) when pressed and held to support new users.
A clear icon makes it easier to find and activate the search function, which increases the overall usability of Lumo.

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…

Have a monthly calendar view that displays a month ahead of the current day
In the current month view, when you are nearing the end of the month, the vast majority of the screen is taken up by past events and therefore often not very useful. Have an additional view that shows the month ahead from the current date.

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 - 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.

Provide a way to keep accounts completely disconnected from AI
No AI, nor company that integrates it, truly cares about user privacy and security. Frankly it makes me reconsider my choice to move to Proton. It's certainly prevented me from moving to any paid tiers

binary file type parsing
According to Lumo, uploaded binary files are only read as a first snippled, and this is no different in the Lumo+ version. Hence, an Excel table or a pdf cannot be parsed or only the first few lines, rendering the function useless. Pls, parse full files. Output of Lumo:
File‑type handling: I can read the first few lines of a text‑based file (CSV, plain‑text, JSON) that you upload, but I cannot open binary formats (PDF, DOCX, XLSX) or run arbitrary parsing libraries. Your annual‑report PDFs and the Excel workbook itself are binary; I can see the file name and a…

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…

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).

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.

"Terse" mode or "conversational" mode
I often don't need 3-page instructions and checklists on the topic I've asked a question about. For example, it recently gave me instructions on how to set up an email. It can be a bit overwhelming and difficult to go back to important information in the conversation.

Link to Lumo app on a F-Droid, .apk (Github)
Since Google Play is not private, it should not be a big deal for a privacy company (Proton) to publish link to a Lumo Android .apk and a Github repository at https://lumo.proton.me/download and at https://protonapps.com (if that is official source). Also I would welcome F-Droid link.
There is a Github repo at https://github.com/ProtonLumo/android-lumo but the parent user shows no signs of validation as a official Proton AG account, despite Lumo claims there should be some check-mark on the user page.

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.1 vote -
delete button (outside of settings)
Can you please move the delete button out of the settings and into the sidebar, or somewhere? I know lots of people keep AI chats, I don't. It seems like extra steps to hide it in settings.

First reply is occasionally given with no words
I find on a fairly frequent reoccurrance that when I ask Lumo a question, it simply spits sources back at me with no words to explain the answer. I have to follow up with a "Please expand" reply in order for it to finally give me an answer. It's not the worst thing, but a little annoying

Allow pasting underscores
I want to paste a regex
.*_([^_]+_[^_]+)$into chat. As soon as I paste, the underscores are removed and my text is converted to italic. I am unable to create a fenced code block with triple backticks. If I create a code block with single backticks and then paste my regex inside, it breaks the code block in half and inserts non-code text.- If the chat box is going to magically remove characters, CTRL+Z should put them back
- I should be able to create a code block, and paste text inside that code block without any magic
