Share.
Never surrender
control.

When you send a file via email or WhatsApp, you lose control over it: whoever receives it can save it, copy it, forward it to others. With CordaV it's different. The file reaches the recipient, but you always keep hold of the rope that tethers it. Lengthen it if you want to grant more time, tighten it to restrict access, cut it whenever you want the file to disappear. The recipient sees only what you permit — nothing more.

THE ROPE — HOW IT WORKS
You
ROPE · ALWAYS IN YOUR CONTROL
The file
limited access
The recipient

Lengthen it — extend the deadline or add more permitted views  ·  Tighten it — reduce permissions or bring the expiry forward  ·  Cut it — the file vanishes instantly from the recipient's device

Lengthen the rope
Want to give them more time? Extend the deadline or increase the number of permitted accesses. You can do this at any moment, even after sending.
Tighten the rope
Changed your mind? Reduce permissions, block the download you had previously authorised, or bring the expiry date forward. All remotely, in real time.
Cut the rope
Revoke access with a single tap. The file disappears immediately from the recipient's device — every device — even if it had already been opened.
Lawyer — Contract under negotiation
You send a draft with a maximum of 3 reads and a 48-hour expiry. The client reads, suggests changes, signs. After 48 hours the rope cuts itself: no stray copies, no document becoming a source of misunderstanding.
Photographer — Selection before payment
Share preview thumbnails: the client can browse but cannot download. They pick the photos they want. Only after payment do you authorise the high-resolution download — with a single tap. The rope only lengthens when you decide.
Designer — Presenting to the client
Show the final renders during the call. Screen recording blocked, no screenshots. If the deal falls through you cut the rope: the files vanish from the client's browser within seconds. Zero risk of leaks before the contract is signed.

// 02 — FOR PHOTOGRAPHERS & CREATORS

The client picks.
You decide
what they receive.

How many times have you shared an entire gallery hoping the client would choose — only to lose control over everything? With CordaV the workflow is different: you show, the client selects, you authorise. Only what you choose to unlock ever reaches the client's hands.

👁
View only
The client can browse watermarked previews. No download possible. Perfect for selection before payment.
Download authorised
Once the client has paid, you unlock the high-resolution download with a single tap — for individual photos or the entire selection.
Integrated paywall
Set a price directly on the gallery. The client pays by card or Apple Pay, you receive 95% immediately into your account. The download unlocks automatically after payment.

// 03 — CONTENT PROTECTION

Nobody walks away
with what is yours.

CordaV doesn't just encrypt files — it actively monitors every attempt to bypass your controls, in real time, on any device.

AI Anti-Photo

The front camera monitors in real time. If it detects someone photographing the screen with a second device, the content hides immediately and you receive an instant alert.

REAL-TIME DETECTION · IMMEDIATE ALERT
Screenshots & recordings blocked

Every attempt to capture the screen — screenshot, screen recording, third-party apps — is detected and blocked at the OS level, on both iOS and Android.

iOS + ANDROID · NATIVE BLOCK
Invisible & visible watermark

Previews display a watermark with the recipient's name, date and IP. If a file leaks, you know exactly where it came from. The watermark follows the content even outside the app.

NAME · DATE · IP · TRACEABLE
Programmable self-destruction

Set an expiry date, a maximum number of opens, or both. When the limit is reached, the file erases itself from every device automatically. No manual intervention required.

EXPIRY · MAX OPENS · AUTOMATIC
Immutable access log

Every open, every screenshot attempt, every access from a new device is recorded with time, location and event type. A log that cannot be altered — always visible to you.

9 TRACKED EVENTS · REAL-TIME LOG
Instant revocation

One tap and the file is gone. Not in a few hours — instantly. Works across all the recipient's devices, even if the file had already been opened, even if the user is offline when you revoke.

INSTANT · CROSS-DEVICE · NO WAITING

// 04 — BROWSER EXTENSION COMING SOON

Know the moment
your file appears
somewhere else.

CordaV's browser extension keeps a silent watch on the web. It monitors whether any file you have shared is being uploaded, republished, or used without your authorisation — and alerts you the instant it detects a match.

01
Fingerprint-based file tracking
Each file you share via CordaV receives a unique cryptographic fingerprint. The extension silently compares uploads and posted content across the web against your fingerprint database — without ever reading the actual file contents.
02
Upload monitoring on major platforms
The extension watches file-upload events on cloud storage services, social platforms, freelance marketplaces, and file-sharing sites. If a CordaV file fingerprint is detected during an upload, you receive an alert within seconds.
03
Instant in-browser alerts
A notification appears directly in your browser — no app required — with the file name, the site where it was detected, the time, and a one-click action to revoke access or flag the infringement.
04
Zero-knowledge architecture
The extension only transmits fingerprints — never file contents. CordaV servers cannot reconstruct your files from fingerprint data. Your privacy is protected even while you are protected.

HOW IT PROTECTS YOU

The extension does not read the contents of pages you visit. It only intercepts upload events and compares fingerprints. All analysis happens locally on your device — nothing is sent to CordaV servers except an anonymised fingerprint hash.

// 05 — PRIVACY & SECURITY

Not even we
can read
your files.

CordaV is built on a fundamental principle: your data belongs to you alone. Protection happens on your device, before any file reaches our servers. We don't have the keys to open them — by design, not by accident.

ZERO ACCESS
Our servers don't hold the keys

The keys to open your files are created on your phone and never leave it. CordaV servers store only already-encrypted data that they cannot decrypt. Even our own engineering team cannot access what you share.

Encryption performed on-device before any transmission
Keys stored in the phone's native secure enclave (iOS Keychain / Android KeyStore)
Each recipient receives a separate, non-shareable key
END-TO-END
Messages are encrypted on your side

The chat with your clients is encrypted on your device before it leaves. The server receives unreadable data, then adds a second layer of encryption. Two independent protection layers: if one is ever compromised, the other holds.

End-to-end encryption applied before sending
Second layer of encryption applied by the server to already-protected data
Messages delete automatically when the conversation is closed
GDPR
GDPR-compliant by design

We collect only the data that is strictly necessary. If you want to delete everything — account, files, messages — you do it with a tap and nothing remains. Servers are in Europe. For healthcare professionals: patients access records without registration, in line with regulatory guidelines.

Servers located in Europe — no data transfers outside the EU
Full deletion guaranteed: account, files, messages, logs
Explicit consent required for every feature that accesses the camera
LOCAL PROTECTION
Safe even if you lose your phone

PIN access to the app with automatic lock after inactivity. Personalised recovery phrase for reliable account recovery. Encrypted exportable backup. If your phone is lost or stolen, your data remains inaccessible.

PIN with configurable auto-lock
Recovery phrase — easy to remember, impossible to guess
Remote full wipe in case of theft

Three layers of
protection.
Nobody else has all three.

Every file you share is protected by three independent encryption systems applied in sequence on your device before any transmission. To breach one of your files, an attacker would need to defeat all three. No other service does this.

01
Military-grade encryption

The first layer uses the same encryption standard adopted by governments and financial institutions worldwide. Considered unbreakable with current technology.

GOVERNMENT STANDARD
02
Mobile-first encryption

The second layer is the same used by Signal and WhatsApp to protect private messages. Designed specifically for mobile devices, resistant to the most sophisticated attacks.

LIKE SIGNAL · LIKE WHATSAPP
03
CordaV proprietary encryption

The third layer is ours — developed in-house, patentable, unique in the world. An additional stratum that renders every CordaV file unintelligible even to someone who had already defeated the first two.

BUILT BY US · PATENTABLE
Blockchain-certified ownership
Keys generated solely on your device
Active protection even offline
GDPR and European regulations compliant

// 07 — FEATURES

Everything
you need.

Secure client chat

End-to-end encrypted messages with your clients, even without the app. Protected attachments up to 8 MB. Messages delete automatically when the conversation closes.

GUEST WITHOUT ACCOUNT · ENCRYPTED ATTACHMENTS
Content monetisation

Put a price on what you share. The client pays by card or Apple Pay, you receive 95% directly into your bank account. No unnecessary middlemen.

95% TO YOU · APPLE PAY · SETUP IN 90 SEC
Access without installing anything

The recipient doesn't need to download any app. They access via browser with a PIN or secure link. All protections remain active even in the web version.

NO APP · LINK + PIN ONLY
Certified proof of ownership

Every file you share receives a permanent ownership certificate on the Bitcoin blockchain. Proof that nobody can alter — valid before a notary or in court.

BITCOIN · OPENTIMESTAMPS · PERMANENT
Enterprise SSO (SAML)

For firms and companies: integration with corporate identity providers (Okta, Microsoft, Google). Users sign in with the same credentials they use every day.

OKTA · AZURE AD · GOOGLE WORKSPACE
MFA
Two-factor authentication

Two-step verification at login: password plus code via email or authenticator app. Even if someone discovers your password, they cannot get in.

EMAIL OTP · TOTP · RECOVERY CODES

Prove it's yours.
Forever.

Every file you share with CordaV receives a permanent ownership certificate on the Bitcoin blockchain. This proof never disappears — even if the file is deleted.

01
File fingerprint
Every file generates a unique cryptographic fingerprint — impossible to forge or reproduce.
02
Bitcoin registration
The fingerprint is permanently recorded on the blockchain. Zero cost, no intermediaries.
03
Verifiable certificate
A QR code that proves your ownership to anyone — notary, court, client in dispute.
04
Indestructible
Even if you delete the file, the certificate remains and automatically records when you chose to destroy it.

Write a message…

The client gets in.
You control
what they see.

No account required for the recipient. They access via browser with a secure link and a PIN. All protections remain fully active.

No app to install — the recipient opens a link in their browser. No registration, no waiting.
PIN or personal link access — you choose how to authenticate. You can set a different code for each recipient.
Protections active in the browser too — anti-photo, screenshot blocking, watermark and access log all work outside the app as well.
Integrated payment — the client pays by card or Apple Pay before content is unlocked. You receive 95% immediately.

// NEXT STEP — THE VISION

A trust infrastructure.
Built from scratch.

Today CordaV gives you control over your files. But the vision is broader: to build the infrastructure on which European professionals can exchange sensitive data without needing to trust any intermediary — not even us.

Two projects in development will reshape how content moves between professionals: a distributed certification network and a direct-transfer system with no central server.

// ROADMAP
TODAY
File control
Triple encryption, AI anti-photo, revocation, blockchain — all available in beta
PHASE 2
Certification blockchain
A distributed network for proof of ownership and content authenticity — independent of any platform
PHASE 3
P2P sharing
Files that travel directly between devices, without touching any server. Not even ours.
// PHASE 2 — IN DEVELOPMENT

A certification network
that depends
on nobody.

Today ownership certification uses Bitcoin as a public network. The next step is building a blockchain designed specifically for European professionals: faster, with predictable costs, and governed by clear data-privacy rules.

Certification independent of any platform
Proof of ownership recognised in legal proceedings
Open network — other services can integrate it
European governance, GDPR-compliant by design

// PHASE 3 — IN DESIGN

Files travel
directly.
No server in between.

In CordaV's final vision, a file passes through no server: it travels directly from your device to the recipient's, encrypted end to end. Our role shrinks to connecting the two devices — then disappearing from the transaction entirely.

No server touches the data during transfer
End-to-end encryption from source to destination
Large file transfers with no storage limits
Rope control remains even in P2P mode

// 12 — FREQUENTLY ASKED QUESTIONS

Have questions?
Answers here.

Can CordaV read my files?+
No. Files are encrypted on your device before they reach our servers. The keys to open them are held only by you — never by us. Even our own engineering team cannot access your content.
What happens to the certificate if I delete a file?+
The blockchain ownership certificate is permanent and cannot be deleted — that's the nature of the blockchain. If you delete a file, the certificate is updated with the date and time you chose to destroy it. The proof of prior ownership remains intact.
Does my client need to install an app?+
No. The recipient opens a link in their browser and enters the PIN you sent them. No registration, no app download. All protections — anti-photo, screenshot blocking, self-destruction — remain active even via the browser.
How does the browser extension detect uploads?+
The extension intercepts file-upload events in the browser and compares a cryptographic fingerprint of the file being uploaded against your CordaV fingerprint database. It never reads the content of web pages you visit and transmits only anonymised fingerprint hashes to CordaV servers — not your files.
How does photo selling work?+
You set a price on the gallery or on individual images. The client pays by card, Apple Pay or Google Pay. As soon as payment is confirmed, the download unlocks automatically. 95% of the amount arrives directly into your bank account.
When will the app be available?+
The private beta launches in the coming months. Those who reach out now receive priority access, the Pro plan at 50% off for the first year, and a direct channel with the team to shape the features in development.
