One-click Upload

Quickly send files with disposable, private links. No account required.

Drag & drop or click to choose

Files are uploaded and stored fully encrypted.

Max: 10 GB per transfer
Upload complete — link created
Expires in: 72h
Note: In a real deployment VDFN would never keep IP logs or map links to identities.

How VDFN protects your files

We designed VDFN to provide a minimal, auditable upload experience that prioritizes privacy. Below is everything users need to understand how files are treated.

No IPs, No Logs

VDFN does not record requester IP addresses, connection metadata, or persistent access logs. Session-level telemetry is ephemeral and used only for short-lived analytics, then discarded.

End-to-End Encryption

Files are encrypted client-side before any transfer (in a real setup). The recipient receives a single-use, random link containing the key. Without the link, the data cannot be decrypted.

Ephemeral Links

By default links auto-expire after a configurable window (e.g., 72 hours). You can set shorter lifetimes for extra safety — expired files are purged.

Data Deletion & Retention

Files are automatically purged after expiry. Retention logs (if any) are minimal and deleted within 48 hours unless legally required otherwise.

Technical overview

Below is a short, implementation-style description suitable for security-minded users and auditors.

  • Client-side encryption: Files are encrypted in the browser using a strong symmetric key derived per-upload. Encrypted blobs are what the server receives.
  • Zero-knowledge links: URLs contain the random decryption token; servers store only the encrypted blob and a pointer. Without the token, the blob is unreadable.
  • Stateless access: Download endpoints require the token in the request; no user accounts are required and there's no persistent session mapping.
  • Delete-on-expire: The storage backend runs secure deletion processes after expiry. For added assurance, overwriting strategies and cryptographically secure deletes are used where supported.

Frequently asked questions

Do you store my IP or identify me?
No. VDFN's default policy is to avoid storing IP addresses or user identifiers. Minimal, short-lived telemetry may be processed for system health, but is purged within 48 hours.
How secure are links?
Links are unguessable (high-entropy tokens). For maximum privacy, share links out-of-band and prefer short lifetimes.
Can you recover deleted files?
No — after expiry and secure deletion, files cannot be recovered. If you need longer retention, configure it before uploading (not available in this demo).
What about legal requests?
If compelled by lawful process, VDFN discloses only data we actually hold. Because we minimize logs and use encrypted storage, what we can provide is limited. Check the full Privacy Policy for details.
