Zero-Log Architecture: How We Built It

RAM-only node operation means connection data never touches persistent storage. Here's the engineering behind our privacy promise.

The Problem with "No-Log" Claims

Most VPN providers claim they don't log. But their architecture tells a different story — they run traditional servers with persistent disks where logs *could* be stored, and you're trusting them not to enable logging.

Trust-based privacy isn't privacy. It's a policy decision that can change at any time.

Architectural Privacy

VynVPN takes a fundamentally different approach. We made logging user activity technically impossible through architectural decisions:

RAM-Only Node Operation

Our VPN nodes boot from a read-only image into RAM. There is no persistent disk attached to node servers. When a node reboots or shuts down, all runtime data — including any connection state — is permanently erased.

What This Means in Practice

  • Connection metadata exists only in volatile memory during an active session
  • No disk = no data to seize in a server raid
  • No disk = no data to recover forensically
  • Rebooting a node destroys all evidence of any connection

The API Layer Separation

Our billing and account management API runs on separate infrastructure from VPN nodes. The API stores:

  • Account email
  • Subscription status
  • Payment references
  • Configuration preferences

It does not store:

  • Connection timestamps
  • IP addresses
  • Bandwidth usage per session
  • Websites visited
  • DNS queries

Key Rotation and Forward Secrecy

Session keys are ephemeral. Each connection generates new cryptographic keys that are never written to disk. Even if an attacker could somehow capture memory at the exact moment of a session, they couldn't decrypt past or future sessions.

Third-Party Verification

We've engaged independent security auditors to verify our no-log claims through:

  1. Infrastructure inspection (confirming RAM-only operation)
  2. Traffic analysis (confirming no outbound logging streams)
  3. Forensic analysis (confirming no recoverable data post-reboot)

Australian Jurisdiction

Australia has no mandatory data retention laws for VPN providers. Combined with our architectural approach, this means there's no legal mechanism to compel logging and no technical capability to comply even if ordered.

Conclusion

Zero-log isn't a policy at VynVPN — it's physics. You can't log what you can't store.
