Work together. Stay unreadable to everyone else.
AKARUP brings together storage, messaging, video calls, secure local agentic AI and secure code execution, end-to-end encrypted with NIST-standardized post-quantum cryptography. Mobile apps, client workstations, servers, connected devices: one protection, across your whole chain. Your office and business software keeps working exactly as before.

post-quantum encryption
Blind Relay: confidential by construction
Each message is encrypted on your device and decrypted on the recipient's. In between, our Blind Relay architecture only carries opaque, uniform envelopes: the server can neither read your content nor tell a message from a file or a note. Confidentiality is not a promise — it is a property of the architecture.
Resilient against ransomware
No version is ever overwritten, only added. A file encrypted by ransomware erases nothing: the earlier version is still there, and a rollback is enough to recover it.
Your tools, unchanged
An AKARUP volume mounts like a disk. Your Word and Excel documents and your business software open and save them just as before. The encryption sits underneath, invisible in daily use.

Messaging
End-to-end encrypted conversations
Write to your contacts knowing only you and they can read the exchange. Messages are encrypted on your device before sending, and synchronized across your devices.
- →Validate a sensitive decision with your accountant without going through email.
- →Discuss a case covered by professional secrecy.
- →Alert the on-call team without exposing incident details.
Groups
The same protection, together
Group conversations enjoy the same cryptography as one-to-one exchanges. Creation, invitations, and member management go through the same encrypted channel as everything else.
- →A crisis channel limited to authorized people only.
- →The executive committee and its confidential exchanges.
- →A project team including an external subcontractor.

Drive
Your files, encrypted and synchronized
Create, open, rename, move, and delete your files from any of your devices. The tree and the contents are encrypted; multi-device synchronization is validated end to end.
- →Case documents consulted from the office and from the courtroom alike.
- →Plans and quotes opened right on the construction site.
- →Your accounting exports archived every night, out of reach of ransomware.

AKARUP FS
An encrypted disk, shared with your team
Mount an AKARUP volume like an ordinary disk. Your documents open and save from your usual software, with no plugin and no change of habit. Invite a group: the volume mounts on each member's machine, end-to-end encrypted.
- →A client file shared between the partners of the firm.
- →A project space opened to an external contractor for the duration of the engagement.
- →Accounting records made available to your accountant, without going through email.

Video calls
Meet without being overheard
Start an audio or video call from a conversation. The stream is end-to-end encrypted between participants, screen sharing included.
- →A crisis call with management, with no meeting room.
- →A remote consultation covered by professional secrecy.
- →A case review with an external partner.
Notes
A notepad that stays private
Take notes inside the app: they are encrypted and synchronized like your files, with no third-party app.
- →The minutes of a confidential meeting, taken on the spot.
- →The technical references for an intervention, at hand.
- →An idea jotted down between two meetings, found again at the office.
Media
Protected photos and documents
Send photos and documents in your conversations and keep them in the Drive, with the same encryption as everything else.
- →Photos of damage sent to the insurer.
- →An ID document exchanged without going through email.
- →Site photos kept and dated.

Automations
Code on your data, without exposing it
Write code, declaratively reference Drive files, and run it in your device's sandbox. The result comes with its fingerprint. This is the first building block of the Code-to-Data model.
- →Check that no duplicates slipped into a client export.
- →Compute totals on a statement without taking it out of the Drive.
- →Produce a summary with its fingerprint, ready to share.
Multi-profile
Multiple isolated accounts on one device
A single device can host several accounts, each with its own keys and its own encrypted space, strictly isolated. Ideal for shared workstations.
- →The front-desk tablet shared between practitioners.
- →The counter workstation used by three agents.
- →Work and personal use strictly separated on one phone.
Blind Relay
The server is a blind relay
Every feature — messages, groups, files, notes, media — travels through the same channel as encrypted envelopes, presented in a unified cryptographic format with no readable business content. That is the Blind Relay architecture: a server compromise does not, by itself, allow reading your end-to-end protected content. The technical metadata required to operate the service is documented on the Security page.
Unified format · content unreadable by the relay · documented metadata
