@Proton
You need to add SimpleLogin compatibility!
It's useless to work hard to maintain all things separately and then dox your user acc in every shared document

How is this request nearly a decade old and Proton STILL does not have even a basic spreadsheet app? Kids in undergrad CompSci programs have been making these things for single semester homework assignments for longer than that.

Uncle Dre is exactly right.

Absolutely agree with this request - the timing couldn't be better for Proton to prioritise a collaborative office suite.

The landscape has fundamentally shifted. With the US Cloud Act in place and American companies increasingly disregarding GDPR compliance, our data simply isn't safe on US-based platforms anymore. We're seeing a growing exodus of privacy-conscious users seeking alternatives, and this trend is only accelerating.

Whilst Nextcloud remains the gold standard for self-hosted collaborative document editing, the reality is that it's far too complex for the average user to set up and maintain. However, if Proton could offer Nextcloud integration directly alongside ProtonDrive - or alternatively implement something like CollaboraOnline as the productivity component - it would be an absolute game-changer.

There's a genuine market opportunity here that's expanding daily. It's not just the security-focused crowd anymore; ordinary Europeans are beginning to understand that entrusting their data to US services is no longer viable. Proton is perfectly positioned to capture this market with a user-friendly, complete office experience that actually respects user privacy.

The feature request mentions preventing downloads/copying, which aligns perfectly with European data protection principles. If Proton could deliver Google Workspace functionality with true zero-knowledge encryption and proper access controls, they'd have a winning formula.

This really should be a top priority.

Europe is in dire need of an alternative to the capabilities offered by Google Workspace and M365. Proton cloud fill this gap with a Proton Workspace!

Work together with Collabora to offer a full Office suite based on LibreOffice with enough storage and collaboration opportunities for Proton members.
This accelerates Proton's efforts for Proton Docs as well.

OnlyOffice is not permitted on EU government computers because of its ownership by P7-Office, a Russian company.

The UK, Singapore and Latvian companies are shell companies for P7-Office.

Better LibreOffice integration would be brilliant!

This should be a top priority for Proton Drive, along with a Linux app which weirdly still doesn't exist

Look into what Skiff was building before they were acquired. Their concept may be a good idea starter.

Its important. But its not important to reinvent the wheel. Collabora Online (online version of LibreOffice Online) works quite well together with Desktop app + Nextcloud integration. Collabora is also very robust and mature. Proton Docs is in a very rought state, and its only Docs that currently present. It must be better to use something else that works than burn a lot of R&D resources on something made in-house that takes years to get mature enough.

+1. Proton, as great as they are, don't have the bandwidth to develop a comprehensive office alternative. And arguably, they shouldn't, because great OSS solutions like collabora online exist.

This particular set of featurse is the only critical bit preventing me from mobing all my cloud services to a proton unlimited, making alternatives that do support collabora very appealing, even when the companies behind are not as good as proton.

This would be amazing. It would go a long way to making proton drive more competitive, and it would save Proton a lot of work.

The folks at Proton have known that users wanted apps for docs and sheets since at least 2016 and they finally delivered docs in 2024.

How long will we have to wait for sheets? I'm turning 60!!! Time's a wastin'!!!

Proton Docs / collaboration suite
(folders and docs similar to GoogleDocs)

Proton mail needs some collaborative word processor and spreadsheet in a drive where people can securely work on it but only the person who owns the files can keep them and no one can download them or copy them.

Libreoffice is robust and the Collabora version has been deployed within Nextcloud for years. Could be a nice partnership with Collabora Productivity.

EPIC: As an user of Proton Drive, I'd like the ability to have a series of online collaboration tools (similar to Google Drive) so that I can create, store, and access documents on the cloud AND migrate off of Google Workspace.

User Story 1: As a Proton Drive user, I'd like the ability to have a cloud-based spreadsheet tool (similar to Google Sheets) so that I can manage spreadsheets online.

User Story 2: As a user of Proton Drive, I would like the ability to be able to store cloud based notes, tasks, or lists (similar to Google Keep, Microsoft OneNote, or Evernote) so I can use one tool to manage my dad-to-day task.

Huge opportunity into integrating LibreOffice into peoton drive

Agreed!

I would finally be able to get out of Google drive completely, if this was possible.

On this take I see more people where they would like a take of proton on spreadsheet, word and more. Where I think that would be great and bring loads of safety and security with it I would love to see when something like that gets added a update to proton drive. Where we can work directly on spreadsheets in the drive and maybe collaborate at the same time with other proton users?
