Einleitung
Dein ganzer Arbeitsbereich.
In einem Browser-Tab.
uOS ist ein echter Desktop, der sich in einem Tab öffnet. 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.

Was du damit machst
Ein Tag Arbeit, alles in einem Fenster.
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 →

Souveränität
Drei Eigenschaften, die Sie nirgendwo sonst zusammen finden werden.
Jedes ist eine Eigenschaft, wie das System aufgebaut ist, kein Marketinganspruch.
01
Gebaut und betrieben in Europa
Infrastructure hosted in the European Union. GDPR-compliant by architecture. Source code, deployment, support — all European.
Warum das wichtig ist
Europäische Infrastruktur bedeutet, dass der US CLOUD Act nicht gilt. Kein extraterritorialer Zugriff auf Ihre Daten, niemals.
Kein US CLOUD Act · Keine extraterritoriale Rechtsprechung
02
Null Cookies, Null Tracking
No cookies. No trackers. No data resale. The server only stores public keys and encrypted blobs — it cannot read your content.
Warum das wichtig ist
Ohne Skripte von Drittanbietern gibt es keinen Supply-Chain-Angriffsvektor. Kein Dritter kann Ihre Lesung profilieren.
Server speichert nur Ciphertext
03
Ihre KI, Ihr Modell
Embedded AI verwendet den von Ihnen gewählten Anbieter: In-House-Modell, Private Cloud-Bereitstellung oder kommerzielle API auf Ihrem eigenen Schlüssel.
Warum das wichtig ist
Ihre Aufforderungen und Gespräche werden nicht verwendet, um kommerzielle Modelle zu trainieren. AI Inferenz bleibt privat auf Ihrem Konto.
Kein aufgezwungener Anbieter, niemals

Ingenieurwesen
Wie wir Ihre Daten schützen.
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.
For engineers — the cryptographic stack EXPAND ↓
| Schicht | Algorithmus | Standard |

UltimaOS is in active development. Access is free during the early access phase, invite-only. Organizations: direct access to the team building the system. Individuals: ask for an invite.

Häufig gefragt
Fragen zum post-quantum verschlüsselten Workspace.
Was ist ein Post-Quantum verschlüsselter Workspace?
Kurze Antwort
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.
Ist UltimaOS GDPR konform?
Kurze Antwort
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 Sicherheitsseite für Einzelheiten.
Welche Anwendungen enthält UltimaOS?
Kurze Antwort
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.
Kann UltimaOS für Unternehmen verwendet werden?
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.
Was unterscheidet UltimaOS von Signal oder 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.
Wie schützt mich die Post-Quanten-Kryptographie heute?
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.
Wo kann ich mehr über die kryptographischen Optionen erfahren?
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.
Wie kann ich UltimaOS ausprobieren?
Der Zugang ist während der Early Access-Phase kostenlos, nur auf Einladung. Einladung anfordern and the team will respond within a few days. Organizations can Direktzugriff beantragen Für einen verlängerten Piloten.
