Hela din arbetsyta.
I en webbläsare flik.

uOS is a real desktop that opens in a tab. Chat, mail, files, documents, spreadsheets, boards, calendar and AI — fifteen applications sharing one file system and one identity, on any device, with nothing to install. Your messages, files and documents are end-to-end encrypted in your browser. Built and run in the European Union, and free forever for individuals and families.

01 Vad du gör med det

Dagens arbete, allt i ett fönster.

Sign in and your desktop is there — the same one, on your laptop, your phone, a borrowed machine. Nothing to install, nothing left behind when you close the tab.

Talk to your people

Message one-to-one or in groups, send voice notes and files, and jump into a video call — with automatic translation across 26 languages when you need it.

Chat and calls →

Handle your mail

A real inbox with folders, attachments, replies and search — plus contacts and a calendar that share the same address book, so scheduling never leaves the workspace.

Mail and calendar →

Keep your files

Folders, drag-and-drop upload, previews and sharing with read, write or admin rights per file — synced across every device you sign in on.

Files and storage →

Write and calculate

Documents and spreadsheets with real-time co-editing — you see who else is in the file, formulas work, and .xlsx files import and export cleanly.

Documents and sheets →

Run your projects

Kanban boards with cards, checklists, assignees and due dates, quick notes for anything you need to capture, and a task list that keeps the rest straight.

Boards, notes and tasks →

Put AI to work

An assistant that reads your documents and helps you write, and a builder that turns a plain-language description into a working internal tool — no server to set up.

AI and Studio →

03 suveränitet

Tre fastigheter du inte hittar tillsammans någon annanstans.

Var och en är en egenskap av hur systemet byggs, inte ett marknadsföringskrav.

01

Byggd och drivs i Europa

Infrastructure hosted in the European Union. GDPR-compliant by architecture. Source code, deployment, support — all European.

Varför detta är viktigt

Europeisk infrastruktur innebär att US CLOUD Act inte gäller. Ingen extraterritoriell åtkomst till dina data någonsin.

Ingen US CLOUD Act · Ingen extraterritoriell jurisdiktion

02

Zero cookies, noll spårning

No cookies. No trackers. No data resale. The server only stores public keys and encrypted blobs — it cannot read your content.

Varför detta är viktigt

Utan tredjepartsskript finns det ingen leverantörskedja attack vektor. Ingen tredje part kan profilera din läsning.

Server butiker chiffertext endast

03

Din AI, din modell

Embedded AI använder den leverantör du väljer: internt modell, privat molndistribution eller kommersiellt API på din egen nyckel.

Varför detta är viktigt

Dina uppmaningar och samtal används inte för att träna kommersiella modeller. AI slutsatsen förblir privat till ditt konto.

Ingen införd leverantör, någonsin

04 Engineering

Hur vi skyddar dina data.

If you are not an engineer, here is the idea: there are computers — quantum computers — that one day will be able to decrypt what is encrypted today. UltimaOS already uses the new generation of cryptography, NIST-standardized, designed to resist these quantum computers. This is the architectural choice, not a feature you can toggle off.

06 Ofta frågade

Frågor om post-quantum krypterad arbetsyta.

Vad är en post-quantum krypterad arbetsyta?

Kort svar

A workspace whose cryptography resists attacks by future quantum computers. UltimaOS uses the NIST-standardized post-quantum algorithms ML-DSA-65 (FIPS 204) for digital signatures and ML-KEM-768 (FIPS 203) for key exchange, layered with classical XChaCha20-Poly1305 symmetric encryption. Private keys never leave your device.

Är UltimaOS GDPR kompatibel?

Kort svar

Yes. Infrastructure is hosted in the European Union, our company is established in the EU, and the architecture is GDPR-compliant by design — we cannot read your data, we do not run advertising, and we set zero cookies. See the security page for details.

Vilka program inkluderar UltimaOS?

Kort svar

Fifteen applications today: Account, Contacts, uMeet, uFiles, uChat, uTodo, uStudio, uAI, uDoc, uSheet, Calendar, uBoards, uMail, uNotes, uLine — with uMarket and others on the roadmap. Chat, mail, files, notes, tasks, documents, spreadsheets and private boards are end-to-end encrypted in your browser; calendar events, AI conversation history and Studio app source are readable server-side today, and each application page says which applies.

Kan UltimaOS användas för företag?

Ja. uOS for Business offers European organizations a zero-knowledge workspace for their teams. Invite-bound membership, signed audit logs, bring-your-own-AI, managed single-tenant deployment, and EU-only data residency.

Vad gör UltimaOS annorlunda än Signal eller Proton?

UltimaOS is a full operating system — chat, mail, files, documents, boards, calendar, contacts — running in your browser with a single private key working across every app. It is post-quantum end-to-end, across every operation, with no fallback to classical primitives. And it is built and operated in the European Union under EU privacy law.

Hur skyddar post-quantum kryptografi mig idag?

A "store now, decrypt later" attack records encrypted traffic today and decrypts it once a sufficiently powerful quantum computer is available. Post-quantum algorithms defeat that attack vector. UltimaOS keys are rotated frequently, so even a quantum breach would yield only a narrow slice of historical data.

Var kan jag lära mig mer om kryptografiska val?

Our engineering pages document the exact cryptographic stack, with references to NIST FIPS 203, FIPS 204, and the relevant IETF RFCs. Those algorithms are public standards you can verify independently. The client ships to your browser as a standard single-page app, so the code that runs can be inspected directly in developer tools — inspectable today, with signed reproducible builds on the roadmap to make it mechanically verifiable. The backend is proprietary; you can query its behaviour from inside uOS, where uAI answers questions about how it works.
