Introducción
Todo tu espacio de trabajo.
En una pestaña del navegador.
uOS es un escritorio real que se abre en una pestaña. 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.

¿Qué haces con eso?
Un día de trabajo, todo en una ventana.
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 →

Tres propiedades que no encontrarán juntos en ningún otro lugar.
Cada uno es una propiedad de cómo se construye el sistema, no una reclamación de marketing.
01
Construido y operado en Europa
Infrastructure hosted in the European Union. GDPR-compliant by architecture. Source code, deployment, support — all European.
Por qué esto importa
La infraestructura europea significa que la Ley de CLOUD de EE.UU. no se aplica. No hay acceso extraterritorial a sus datos, nunca.
No Ley de la CLOUD de los Estados Unidos · No jurisdicción extraterritorial
02
Cero galletas, cero seguimiento
No cookies. No trackers. No data resale. The server only stores public keys and encrypted blobs — it cannot read your content.
Por qué esto importa
Sin scripts de terceros, no hay vector de ataque de cadena de suministro. Ningún tercero puede perfilar su lectura.
Servidor almacena ciphertext sólo
03
Tu IA, tu modelo
La IA incorporada utiliza el proveedor que elija: modelo interno, implementación de nube privada o API comercial en su propia clave.
Por qué esto importa
Sus indicaciones y conversaciones no se utilizan para entrenar modelos comerciales. La inferencia de AI se mantiene privada a su cuenta.
No hay proveedor impuesto, nunca

Ingeniería
Cómo protegemos sus datos.
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 ↓
| Layer | Algoritm | Estándar |

Preguntas frecuentes
Preguntas sobre el espacio de trabajo cifrado post-quantum.
¿Qué es un espacio de trabajo cifrado post-quantum?
Respuesta corta
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.
¿Es compatible UltimaOS GDPR?
Respuesta corta
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 página de seguridad para detalles.
¿Qué aplicaciones incluye UltimaOS?
Respuesta corta
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.
¿Se puede utilizar UltimaOS para negocios?
Sí. 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.
¿Qué hace que UltimaOS sea diferente de Signal o 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.
¿Cómo me protege la criptografía post-quantum hoy?
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.
¿Dónde puedo aprender más sobre las opciones criptográficas?
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.
¿Cómo puedo probar UltimaOS?
El acceso es gratuito durante la fase de acceso temprano, solo para invitados. Solicitar una invitación and the team will respond within a few days. Organizations can solicitud de acceso directo para un piloto extendido.
