Stop sending ten-million-euro villas over WhatsApp.
ARVENS is the digital vault for ultra-luxury real estate. 4K photographs, sealed by a digital NDA, traced in real time.
- Digital NDA
- Named audit
- Native 4K
I — The reality
A photograph on WhatsApp is three things: compressed, anonymous, untraceable.
You send Mr Arnault's villa to a buyer. The attachment is degraded to 200 KB, no confidentiality undertaking has been signed, and you have no idea whether it has been opened, forwarded, or screenshotted. It is the world's most demanding real-estate practice, on the world's least secure tool.
95% compression
WhatsApp brings an 80 MB photograph down to a few hundred kilobytes. The exceptional asset becomes an ordinary thumbnail.
No undertaking
No confidentiality clause is signed before the file is opened. You rely on a buyer's word. And in off-market, a word is not a deed.
No traceability
You don't know who opened the file, from which country, on which device. The photograph circulates, and you follow the silence.
II — The presentation
A twelve-million villa does not deserve a 200 KB thumbnail.
On generic tools, your photographs are compressed, cropped, stripped of their frame. ARVENS delivers exactly what came out of the camera — pixel for pixel, in a setting designed for the property.

Try ARVENSIII — The answer
Three principles: confidentiality, traceability, fidelity.
Digital NDA
Before the first image, the buyer reads and accepts a time-stamped, signed confidentiality agreement. No signature, no access. No access, no leak.
- Enforceable in French, English, Spanish and Arabic
- Time-stamped signature, archived for 10 years
- No documented leak since launch
Real-time audit
Every opening is timestamped, geolocated, signed. You see exactly who has viewed your dossier, from which city, at what time, on what device.
- IP, city, browser, device — on every opening
- Real-time notification on each acceptance
- Legal PDF report, downloadable 24/7
Native 4K
Your photographs arrive intact. No compression, no degradation. Pixel-perfect, exactly as your photographer delivered them.
- Native 4K photographs — zero compression
- Scenographed gallery worthy of the property
- Branded URL arvens.app — yours, not WhatsApp's
IV — How it works
Three minutes to turn a WhatsApp send into a legal proof.
- 01
Create a dossier
Buyer's name, NDA language, link expiration date. Drop your 4K photographs. ARVENS encrypts them and locks them in the vault.
- 02
Share the link
A unique, named, sealed link. Copy it, paste it on WhatsApp or in your usual buyer email. Same gesture as before. But protected.
- 03
Track in real time
The buyer signs the NDA, opens the dossier. You receive the timestamp, IP, city, browser. Download the legal PDF report at any moment.
See it in action
From sharing to enforceable proof.
An agent creates a dossier, the buyer signs the NDA, the gallery unlocks, and every view is logged. The full ARVENS flow, from sharing to legal proof.
